-;; About ps-print:
-;; --------------
-;; This package provides printing of Emacs buffers on PostScript
-;; printers; the buffer's bold and italic text attributes are
-;; preserved in the printer output. Ps-print is intended for use with
-;; Emacs 19 (Lucid or FSF) and a fontifying package such as font-lock
-;; or hilit.
-;;
-;; Installing ps-print:
-;; -------------------
-;; Place ps-print somewhere in your load-path and byte-compile it.
-;; Load ps-print with (require 'ps-print).
-;;
-;; Using ps-print:
-;; --------------
-;; The variables ps-bold-faces and ps-italic-faces *must* contain
-;; lists of the faces that you wish to print in bold or italic font.
-;; These variables already contain some default values, but most users
-;; will probably have to add some of their own. To add a face to one
-;; of these lists, put code something like the following into your
-;; .emacs startup file:
-;;
-;; (setq ps-bold-faces (cons 'my-bold-face ps-bold-faces))
-;;
-;; Ps-print's printer interface is governed by the variables ps-lpr-
-;; command and ps-lpr-switches; these are analogous to the variables
-;; lpr-command and lpr-switches in the Emacs lpr package.
-;;
-;; To use ps-print, invoke the command ps-print-buffer-with-faces.
-;; This will generate a PostScript image of the current buffer and
-;; send it to the printer. Precede this command with a numeric prefix
-;; (C-u), and the PostScript output will be saved in a file; you will
-;; be prompted for a filename. Also see the functions ps-print-
-;; buffer, ps-print-region, and ps-print-region-with-faces.
-;;
-;; I recommend binding ps-print-buffer-with-faces to a key sequence;
-;; on a Sun 4 keyboard, for example, you can bind to the PrSc key (aka
-;; r22):
-;;
-;; (global-set-key 'f22 'ps-print-buffer-with-faces)
-;; (global-set-key '(shift f22) 'ps-print-region-with-faces)
-;;
-;; Or, as I now prefer, you can also bind the ps-spool- functions to
-;; keys; here's my bindings:
-;;
-;; (global-set-key 'f22 'ps-spool-buffer-with-faces)
-;; (global-set-key '(shift f22) 'ps-spool-region-with-faces)
-;; (global-set-key '(control f22) 'ps-despool)
-;;
-;; Using ps-print with other Emacses:
-;; ---------------------------------
-;; Although it was intended for use with Emacs 19, ps-print will also work
-;; with Emacs version 18; you won't get fancy fontified output, but it
-;; should work.
-;;
-;; A few words about support:
-;; -------------------------
-;; Despite its appearance, with comment blocks, usage instructions, and
-;; documentation strings, ps-print is not a supported package. That's all
-;; a masquerade. Ps-print is something I threw together in my spare time--
-;; an evening here, a Saturday there--to make my printouts look like my
-;; Emacs buffers. It works, but is not complete.
-;;
-;; Unfortunately, supporting elisp code is not my job and, now that I have
-;; what I need out of ps-print, additional support is going to be up to
-;; you, the user. But that's the spirit of Emacs, isn't it? I call on
-;; all who use this package to help in developing it further. If you
-;; notice a bug, fix it and send me the patches. If you add a feature,
-;; again, send me the patches. I will collect all such contributions and
-;; periodically post the updates to the appropriate places.
-;;
-;; A few more words about support:
-;; ------------------------------
-;; The response to my call for public support of ps-print has been
-;; terrific. With the exception of the spooling mechanism, all the new
-;; features in this version of ps-print were contributed by users. I have
-;; some contributed code for printing headers that I'll add to the next
-;; release of ps-print, but there are still other features that users can
-;; write. See the "Features to Add" list a little further on, and keep
-;; that elisp rolling in.
-;;
-;; Please send all bug fixes and enhancements to me, thompson@wg2.waii.com.
-;;
-;; New in version 1.5
-;; ------------------
-;; Support for Emacs 19. Works with both overlays and text
-;; properties.
-;;
-;; Underlining.
-;;
-;; Local spooling; see function ps-spool-buffer.
-;;
-;; Support for ISO8859-1 character set.
-;;
-;; Page breaks are now handled correctly.
-;;
-;; Percentages reported while formatting are now correct.
-;;
-;; Known bugs and limitations of ps-print:
-;; --------------------------------------
-;; Slow. (Byte-compiling helps.)
-;;
-;; The PostScript needs review/cleanup/enhancing by a PS expert.
-;;
-;; ASCII Control characters other than tab, linefeed and pagefeed are
-;; not handled.
-;;
-;; The mechanism for determining whether a stretch of characters
-;; should be printed bold, italic, or plain is crude and extremely
-;; limited.
-;;
-;; Faces are always treated as opaque.
-;;
-;; Font names are hardcoded.
-;;
-;; Epoch not fully supported.
-;;
-;; Tested with only one PostScript printer.
-;;
-;; Features to add:
-;; ---------------
-;; Line numbers.
-;;
-;; Simple headers with date, filename, and page numbers.
-;;
-;; Gaudy headers a`la enscript and mp.
-;;
-;; 2-up and 4-up capability.
-;;
-;; Wide-print capability.

-with the standard bold, italic, and bold-italic faces, with font-lock's
-faces, and with the faces used by gnus and rmail.

-Courier-Oblique, and Courier-BoldOblique.

-
-"Generate and spool a PostScript image of the buffer.
-
-This function is essentially the same as function ps-print-buffer
-except that the PostScript image is saved in a local buffer to be sent
-to the printer later.
-
-Each time you call one of the ps-spool- functions, the generated
-PostScript is appended to a buffer named *PostScript*; to send the
-spooled PostScript to the printer, or save it to a file, use the command
-ps-despool.
-
-If the variable ps-spool-duplex is non-nil, then the spooled PostScript
-is padded with blank pages, when needed, so that each printed buffer
-will start on a front page when printed on a duplex printer (a printer
-that prints on both sides on the paper). Users of non-duplex printers
-will want to leave ps-spool-duplex nil.
-
-The spooling mechanism was designed for printing lots of small files
-(mail messages or netnews articles) to save paper that would otherwise
-be wasted on banner pages, and to make it easier to find your output at
-the printer (it's easier to pick up one 50-page printout than to find 50
-single-page printouts).
-
-Ps-print has a hook in the kill-emacs-hook list so that you won't
-accidently quit from Emacs while you have unprinted PostScript waiting
-in the spool buffer. If you do attempt to exit with spooled PostScript,
-you'll be asked if you want to print it, and if you decline, you'll be
-asked to confirm the exit; this is modeled on the confirmation that
-Emacs uses for modified buffers.

+;;; Commentary:
+
+;; ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
+;;
+;; About ps-print
+;; --------------
+;;
+;; This package provides printing of Emacs buffers on PostScript printers;
+;; the buffer's bold and italic text attributes are preserved in the printer
+;; output. ps-print is intended for use with Emacs or Lucid Emacs, together
+;; with a fontifying package such as font-lock or hilit.
+;;
+;; ps-print uses the same face attributes defined through font-lock or hilit
+;; to print a PostScript file, but some faces are better seeing on the screen
+;; than on paper, specially when you have a black/white PostScript printer.
+;;
+;; ps-print allows a remap of face to another one that it is better to print,
+;; for example, the face font-lock-comment-face (if you are using font-lock)
+;; could have bold or italic attribute when printing, besides foreground color.
+;; This remap improves printing look (see How Ps-Print Maps Faces).
+;;
+;;
+;; Using ps-print
+;; --------------
+;;
+;; ps-print provides eight commands for generating PostScript images
+;; of Emacs buffers:
+;;
+;; ps-print-buffer
+;; ps-print-buffer-with-faces
+;; ps-print-region
+;; ps-print-region-with-faces
+;; ps-spool-buffer
+;; ps-spool-buffer-with-faces
+;; ps-spool-region
+;; ps-spool-region-with-faces
+;;
+;; These commands all perform essentially the same function: they
+;; generate PostScript images suitable for printing on a PostScript
+;; printer or displaying with GhostScript. These commands are
+;; collectively referred to as "ps-print- commands".
+;;
+;; The word "print" or "spool" in the command name determines when the
+;; PostScript image is sent to the printer:
+;;
+;; print - The PostScript image is immediately sent to the
+;; printer;
+;;
+;; spool - The PostScript image is saved temporarily in an
+;; Emacs buffer. Many images may be spooled locally
+;; before printing them. To send the spooled images
+;; to the printer, use the command `ps-despool'.
+;;
+;; The spooling mechanism was designed for printing lots of small
+;; files (mail messages or netnews articles) to save paper that would
+;; otherwise be wasted on banner pages, and to make it easier to find
+;; your output at the printer (it's easier to pick up one 50-page
+;; printout than to find 50 single-page printouts).
+;;
+;; ps-print has a hook in the `kill-emacs-hook' so that you won't
+;; accidentally quit from Emacs while you have unprinted PostScript
+;; waiting in the spool buffer. If you do attempt to exit with
+;; spooled PostScript, you'll be asked if you want to print it, and if
+;; you decline, you'll be asked to confirm the exit; this is modeled
+;; on the confirmation that Emacs uses for modified buffers.
+;;
+;; The word "buffer" or "region" in the command name determines how
+;; much of the buffer is printed:
+;;
+;; buffer - Print the entire buffer.
+;;
+;; region - Print just the current region.
+;;
+;; The -with-faces suffix on the command name means that the command
+;; will include font, color, and underline information in the
+;; PostScript image, so the printed image can look as pretty as the
+;; buffer. The ps-print- commands without the -with-faces suffix
+;; don't include font, color, or underline information; images printed
+;; with these commands aren't as pretty, but are faster to generate.
+;;
+;; Two ps-print- command examples:
+;;
+;; ps-print-buffer - print the entire buffer,
+;; without font, color, or
+;; underline information, and
+;; send it immediately to the
+;; printer.
+;;
+;; ps-spool-region-with-faces - print just the current region;
+;; include font, color, and
+;; underline information, and
+;; spool the image in Emacs to
+;; send to the printer later.
+;;
+;;
+;; Invoking Ps-Print
+;; -----------------
+;;
+;; To print your buffer, type
+;;
+;; M-x ps-print-buffer
+;;
+;; or substitute one of the other seven ps-print- commands. The
+;; command will generate the PostScript image and print or spool it as
+;; specified. By giving the command a prefix argument
+;;
+;; C-u M-x ps-print-buffer
+;;
+;; it will save the PostScript image to a file instead of sending it
+;; to the printer; you will be prompted for the name of the file to
+;; save the image to. The prefix argument is ignored by the commands
+;; that spool their images, but you may save the spooled images to a
+;; file by giving a prefix argument to `ps-despool':
+;;
+;; C-u M-x ps-despool
+;;
+;; When invoked this way, `ps-despool' will prompt you for the name of
+;; the file to save to.
+;;
+;; Any of the `ps-print-' commands can be bound to keys; I recommend
+;; binding `ps-spool-buffer-with-faces', `ps-spool-region-with-faces',
+;; and `ps-despool'. Here are the bindings I use on my Sun 4 keyboard:
+;;
+;; (global-set-key 'f22 'ps-spool-buffer-with-faces) ;f22 is prsc
+;; (global-set-key '(shift f22) 'ps-spool-region-with-faces)
+;; (global-set-key '(control f22) 'ps-despool)
+;;
+;;
+;; The Printer Interface
+;; ---------------------
+;;
+;; The variables `ps-lpr-command' and `ps-lpr-switches' determine what
+;; command is used to send the PostScript images to the printer, and
+;; what arguments to give the command. These are analogous to
+;; `lpr-command' and `lpr-switches'.
+;;
+;; Make sure that they contain appropriate values for your system;
+;; see the usage notes below and the documentation of these variables.
+;;
+;; The variable `ps-printer-name' determines the name of a local printer for
+;; printing PostScript files.
+;;
+;; NOTE: `ps-lpr-command' and `ps-lpr-switches' take their initial values
+;; from the variables `lpr-command' and `lpr-switches'. If you have
+;; `lpr-command' set to invoke a pretty-printer such as `enscript',
+;; then ps-print won't work properly. `ps-lpr-command' must name
+;; a program that does not format the files it prints.
+;; `ps-printer-name' takes its initial value from the variable
+;; `printer-name'.
+;;
+;; The variable `ps-print-region-function' specifies a function to print the
+;; region on a PostScript printer.
+;; See definition of `call-process-region' for calling conventions. The fourth
+;; and the sixth arguments are both nil.
+;;
+;; If you're using Emacs for Windows 95/98/NT or MS-DOS, don't forget to
+;; customize the following variables: `ps-printer-name', `ps-lpr-command',
+;; `ps-lpr-switches' and `ps-spool-config'. See these variables documentation
+;; in the code or by typing, for example, C-h v ps-printer-name RET.
+;;
+;;
+;; The Page Layout
+;; ---------------
+;;
+;; All dimensions are floats in PostScript points.
+;; 1 inch == 2.54 cm == 72 points
+;; 1 cm == (/ 1 2.54) inch == (/ 72 2.54) points
+;;
+;; The variable `ps-paper-type' determines the size of paper ps-print formats
+;; for; it should contain one of the symbols: `a4' `a3' `letter' `legal'
+;; `letter-small' `tabloid' `ledger' `statement' `executive' `a4small' `b4'
+;; `b5'.
+;;
+;; The variable `ps-landscape-mode' determines the orientation of the printing
+;; on the page: nil means `portrait' mode, non-nil means `landscape' mode.
+;; There is no oblique mode yet, though this is easy to do in ps.
+;;
+;; In landscape mode, the text is NOT scaled: you may print 70 lines in portrait
+;; mode and only 50 lines in landscape mode. The margins represent margins in
+;; the printed paper: the top margin is the margin between the top of the page
+;; and the printed header, whatever the orientation is.
+;;
+;; The variable `ps-number-of-columns' determines the number of columns both in
+;; landscape and portrait mode.
+;; You can use:
+;; - (the standard) one column portrait mode.
+;; - (my favorite) two columns landscape mode (which spares trees).
+;; but also:
+;; - one column landscape mode for files with very long lines.
+;; - multi-column portrait or landscape mode.
+;;
+;; The variable `ps-print-upside-down' determines other orientation for printing
+;; page: nil means `normal' printing, non-nil means `upside-down' printing. The
+;; default value is nil (`normal' printing).
+;;
+;; The `upside-down' orientation can be used in portrait or landscape mode.
+;;
+;;
+;; Horizontal layout
+;; -----------------
+;;
+;; The horizontal layout is determined by the variables
+;; `ps-left-margin' `ps-inter-column' `ps-right-margin'
+;; as follows:
+;;
+;; ------------------------------------------
+;; | | | | | | | |
+;; | lm | text | ic | text | ic | text | rm |
+;; | | | | | | | |
+;; ------------------------------------------
+;;
+;; If `ps-number-of-columns' is 1, `ps-inter-column' is not relevant.
+;; Usually, lm = rm > 0 and ic = lm
+;; If (ic < 0), the text of adjacent columns can overlap.
+;;
+;;
+;; Vertical layout
+;; ---------------
+;;
+;; The vertical layout is determined by the variables
+;; `ps-bottom-margin' `ps-top-margin' `ps-header-offset'
+;; as follows:
+;;
+;; |--------| |--------|
+;; | tm | | tm |
+;; |--------| |--------|
+;; | header | | |
+;; |--------| | |
+;; | ho | | |
+;; |--------| or | text |
+;; | | | |
+;; | text | | |
+;; | | | |
+;; |--------| |--------|
+;; | bm | | bm |
+;; |--------| |--------|
+;;
+;; If `ps-print-header' is nil, `ps-header-offset' is not relevant.
+;; The margins represent margins in the printed paper:
+;; the top margin is the margin between the top of the page
+;; and the printed header, whatever the orientation is.
+;;
+;;
+;; Headers
+;; -------
+;;
+;; ps-print can print headers at the top of each column or at the top
+;; of each page; the default headers contain the following four items:
+;; on the left, the name of the buffer and, if the buffer is visiting
+;; a file, the file's directory; on the right, the page number and
+;; date of printing. The default headers look something like this:
+;;
+;; ps-print.el 1/21
+;; /home/jct/emacs-lisp/ps/new 94/12/31
+;;
+;; When printing on duplex printers, left and right are reversed so
+;; that the page numbers are toward the outside (cf. `ps-spool-duplex').
+;;
+;; Headers are configurable:
+;; To turn them off completely, set `ps-print-header' to nil.
+;; To turn off the header's gaudy framing box,
+;; set `ps-print-header-frame' to nil.
+;;
+;; To print only one header at the top of each page,
+;; set `ps-print-only-one-header' to t.
+;;
+;; The font family and size of text in the header are determined
+;; by the variables `ps-header-font-family', `ps-header-font-size' and
+;; `ps-header-title-font-size' (see below).
+;;
+;; The variable `ps-header-line-pad' determines the portion of a header
+;; title line height to insert between the header frame and the text
+;; it contains, both in the vertical and horizontal directions:
+;; .5 means half a line.
+
+;; Page numbers are printed in `n/m' format, indicating page n of m pages;
+;; to omit the total page count and just print the page number,
+;; set `ps-show-n-of-n' to nil.
+;;
+;; The amount of information in the header can be changed by changing
+;; the number of lines. To show less, set `ps-header-lines' to 1, and
+;; the header will show only the buffer name and page number. To show
+;; more, set `ps-header-lines' to 3, and the header will show the time of
+;; printing below the date.
+;;
+;; To change the content of the headers, change the variables
+;; `ps-left-header' and `ps-right-header'.
+;; These variables are lists, specifying top-to-bottom the text
+;; to display on the left or right side of the header.
+;; Each element of the list should be a string or a symbol.
+;; Strings are inserted directly into the PostScript arrays,
+;; and should contain the PostScript string delimiters '(' and ')'.
+;;
+;; Symbols in the header format lists can either represent functions
+;; or variables. Functions are called, and should return a string to
+;; show in the header. Variables should contain strings to display in
+;; the header. In either case, function or variable, the PostScript
+;; string delimiters are added by ps-print, and should not be part of
+;; the returned value.
+;;
+;; Here's an example: say we want the left header to display the text
+;;
+;; Moe
+;; Larry
+;; Curly
+;;
+;; where we have a function to return "Moe"
+;;
+;; (defun moe-func ()
+;; "Moe")
+;;
+;; a variable specifying "Larry"
+;;
+;; (setq larry-var "Larry")
+;;
+;; and a literal for "Curly". Here's how `ps-left-header' should be
+;; set:
+;;
+;; (setq ps-left-header (list 'moe-func 'larry-var "(Curly)"))
+;;
+;; Note that Curly has the PostScript string delimiters inside his
+;; quotes -- those aren't misplaced lisp delimiters!
+;;
+;; Without them, PostScript would attempt to call the undefined
+;; function Curly, which would result in a PostScript error.
+;;
+;; Since most printers don't report PostScript errors except by
+;; aborting the print job, this kind of error can be hard to track down.
+;;
+;; Consider yourself warned!
+;;
+;;
+;; PostScript Prologue Header
+;; --------------------------
+;;
+;; It is possible to add PostScript prologue header comments besides that
+;; ps-print generates by setting the variable `ps-print-prologue-header'.
+;;
+;; `ps-print-prologue-header' may be a string or a symbol function which returns
+;; a string. Note that this string is inserted on PostScript prologue header
+;; section which is used to define some document characteristic through
+;; PostScript special comments, like "%%Requirements: jog\n".
+;;
+;; By default `ps-print-prologue-header' is nil.
+;;
+;; ps-print always inserts the %%Requirements: comment, so if you need to insert
+;; more requirements put them first in `ps-print-prologue-header' using the
+;; "%%+" comment. For example, if you need to set numcopies to 3 and jog on
+;; requirements and set %%LanguageLevel: to 2, do:
+;;
+;; (setq ps-print-prologue-header
+;; "%%+ numcopies(3) jog\n%%LanguageLevel: 2\n")
+;;
+;; The duplex requirement is inserted by ps-print (see section Duplex Printers).
+;;
+;; Do not forget to terminate the string with "\n".
+;;
+;; For more information about PostScript document comments, see:
+;; PostScript Language Reference Manual (2nd edition)
+;; Adobe Systems Incorporated
+;; Appendix G: Document Structuring Conventions -- Version 3.0
+;;
+;; It is also possible to add an user defined PostScript prologue code before
+;; all generated prologue code by setting the variable
+;; `ps-user-defined-prologue'.
+;;
+;; `ps-user-defined-prologue' may be a string or a symbol function which returns
+;; a string. Note that this string is inserted after `ps-adobe-tag' and
+;; PostScript prologue comments, and before ps-print PostScript prologue code
+;; section. That is, this string is inserted after error handler initialization
+;; and before ps-print settings.
+;;
+;; By default `ps-user-defined-prologue' is nil.
+;;
+;; It's recommended to initiate and terminate the string with "\n".
+;;
+;; It's strongly recommended only insert PostScript code and/or comments
+;; specific for your printing system particularities. For example, some special
+;; initialization that only your printing system needs.
+;;
+;; Do not insert code for duplex printing, n-up printing or error handler,
+;; ps-print handles this in a suitable way.
+;;

+;; PostScript Language Reference Manual (2nd edition)
+;; Adobe Systems Incorporated
+;;
+;;
+;; PostScript Error Handler
+;; ------------------------
+;;
+;; ps-print instruments generated PostScript code with an error handler.
+;;
+;; The variable `ps-error-handler-message' specifies where the error handler
+;; message should be sent.
+;;
+;; Valid values are:
+;;
+;; none catch the error and *DON'T* send any message.
+;;
+;; paper catch the error and print on paper the error message.
+;; This is the default value.
+;;
+;; system catch the error and send back the error message to
+;; printing system. This is useful only if printing system
+;; send back an email reporting the error, or if there is
+;; some other alternative way to report back the error from
+;; the system to you.
+;;
+;; paper-and-system catch the error, print on paper the error message and
+;; send back the error message to printing system.
+;;
+;; Any other value is treated as `paper'.
+;;
+;;
+;; Duplex Printers
+;; ---------------
+;;
+;; If you have a duplex-capable printer (one that prints both sides of the
+;; paper), set `ps-spool-duplex' to t.
+;; ps-print will insert blank pages to make sure each buffer starts on the
+;; correct side of the paper.
+;;
+;; The variable `ps-spool-config' specifies who is the responsable for setting
+;; duplex and page size switches. Valid values are:
+;;
+;; lpr-switches duplex and page size are configured by `ps-lpr-switches'.
+;; Don't forget to set `ps-lpr-switches' to select duplex
+;; printing for your printer.
+;;
+;; setpagedevice duplex and page size are configured by ps-print using the
+;; setpagedevice PostScript operator.
+;;
+;; nil duplex and page size are configured by ps-print *not* using
+;; the setpagedevice PostScript operator.
+;;
+;; Any other value is treated as nil.
+;;
+;; The default value is `lpr-switches'.
+;;
+;; WARNING: The setpagedevice PostScript operator affects ghostview utility when
+;; viewing file generated using landscape. Also on some printers,
+;; setpagedevice affects zebra stripes; on other printers,
+;; setpagedevice affects the left margin.
+;; Besides all that, if your printer does not have the paper size
+;; specified by setpagedevice, your printing will be aborted.
+;; So, if you need to use setpagedevice, set `ps-spool-config' to
+;; `setpagedevice', generate a test file and send it to your printer;
+;; if the printed file isn't ok, set `ps-spool-config' to nil.
+;;
+;; The variable `ps-spool-tumble' specifies how the page images on opposite
+;; sides of a sheet are oriented with respect to each other. If
+;; `ps-spool-tumble' is nil, produces output suitable for binding on the left or
+;; right. If `ps-spool-tumble' is non-nil, produces output suitable for binding
+;; at the top or bottom. It has effect only when `ps-spool-duplex' is non-nil.
+;; The default value is nil.
+;;
+;; Some printer system prints a header page and forces the first page be printed
+;; on header page back, when using duplex. If your printer system has this
+;; behavior, set variable `ps-banner-page-when-duplexing' to t.
+;;
+;; When `ps-banner-page-when-duplexing' is non-nil means the very first page is
+;; skipped. It's like the very first character of buffer (or region) is ^L
+;; (\014).
+;;
+;; The default for `ps-banner-page-when-duplexing' is nil (*don't* skip the very
+;; first page).
+;;
+;;
+;; N-up Printing
+;; -------------
+;;
+;; The variable `ps-n-up-printing' specifies the number of pages per sheet of
+;; paper. The value specified must be between 1 and 100. The default is 1.
+;;
+;; NOTE: some PostScript printer may crash printing if `ps-n-up-printing' is set
+;; to a high value (for example, 23). If this happens, set a lower value.
+;;
+;; The variable `ps-n-up-margin' specifies the margin in points between the
+;; sheet border and the n-up printing. The default is 1 cm (or 0.3937 inches,
+;; or 28.35 points).
+;;
+;; If variable `ps-n-up-border-p' is non-nil a border is drawn around each page.
+;; The default is t.
+;;
+;; The variable `ps-n-up-filling' specifies how page matrix is filled on each
+;; sheet of paper. Following are the valid values for `ps-n-up-filling' with a
+;; filling example using a 3x4 page matrix:
+;;
+;; left-top 1 2 3 4 left-bottom 9 10 11 12
+;; 5 6 7 8 5 6 7 8
+;; 9 10 11 12 1 2 3 4
+;;
+;; right-top 4 3 2 1 right-bottom 12 11 10 9
+;; 8 7 6 5 8 7 6 5
+;; 12 11 10 9 4 3 2 1
+;;
+;; top-left 1 4 7 10 bottom-left 3 6 9 12
+;; 2 5 8 11 2 5 8 11
+;; 3 6 9 12 1 4 7 10
+;;
+;; top-right 10 7 4 1 bottom-right 12 9 6 3
+;; 11 8 5 2 11 8 5 2
+;; 12 9 6 3 10 7 4 1
+;;
+;; Any other value is treated as left-top.
+;;
+;; The default value is left-top.
+;;
+;;
+;; Control And 8-bit Characters
+;; ----------------------------
+;;
+;; The variable `ps-print-control-characters' specifies whether you want to see
+;; a printable form for control and 8-bit characters, that is, instead of
+;; sending, for example, a ^D (\004) to printer, it is sent the string "^D".
+;;
+;; Valid values for `ps-print-control-characters' are:
+;;
+;; 8-bit This is the value to use when you want an ASCII encoding of
+;; any control or non-ASCII character. Control characters are
+;; encoded as "^D", and non-ASCII characters have an
+;; octal encoding.
+;;
+;; control-8-bit This is the value to use when you want an ASCII encoding of
+;; any control character, whether it is 7 or 8-bit.
+;; European 8-bits accented characters are printed according
+;; the current font.
+;;
+;; control Only ASCII control characters have an ASCII encoding.
+;; European 8-bits accented characters are printed according
+;; the current font.
+;;
+;; nil No ASCII encoding. Any character is printed according the
+;; current font.
+;;
+;; Any other value is treated as nil.
+;;
+;; The default is `control-8-bit'.
+;;
+;; Characters TAB, NEWLINE and FORMFEED are always treated by ps-print engine.
+;;
+;;
+;; Printing Multi-byte Buffer
+;; --------------------------
+;;
+;; See ps-mule.el for documentation.
+;;
+;;
+;; Line Number
+;; -----------
+;;
+;; The variable `ps-line-number' specifies whether to number each line;
+;; non-nil means do so. The default is nil (don't number each line).
+;;
+;; The variable `ps-line-number-step' specifies the interval that line number is
+;; printed. For example, if `ps-line-number-step' is set to 2, the printing
+;; will look like:
+;;
+;; 1 one line
+;; one line
+;; 3 one line
+;; one line
+;; 5 one line
+;; one line
+;; ...
+;;
+;; Valid values are:
+;;
+;; integer an integer that specifies the interval that line number is
+;; printed. If it's lesser than or equal to zero, it's used the
+;; value 1.
+;;
+;; `zebra' specifies that only the line number of the first line in a zebra
+;; stripe is to be printed.
+;;
+;; Any other value is treated as `zebra'.
+;; The default value is 1, so each line number is printed.
+;;
+;; The variable `ps-line-number-start' specifies the starting point in the
+;; interval given by `ps-line-number-step'. For example, if
+;; `ps-line-number-step' is set to 3 and `ps-line-number-start' is set to 3, the
+;; printing will look like:
+;;
+;; one line
+;; one line
+;; 3 one line
+;; one line
+;; one line
+;; 6 one line
+;; one line
+;; one line
+;; 9 one line
+;; one line
+;; ...
+;;
+;; The values for `ps-line-number-start':
+;;
+;; * If `ps-line-number-step' is an integer, must be between 1 and the value
+;; of `ps-line-number-step' inclusive.
+;;
+;; * If `ps-line-number-step' is set to `zebra', must be between 1 and the
+;; value of `ps-zebra-strip-height' inclusive.
+;;
+;; The default value is 1, so the line number of the first line of each interval
+;; is printed.
+;;
+;;
+;; Zebra Stripes
+;; -------------
+;;
+;; Zebra stripes are a kind of background that appear "underneath" the text
+;; and can make the text easier to read. They look like this:
+;;
+;; XXXXXXXXXXXXXXXXXXXXXXXX
+;; XXXXXXXXXXXXXXXXXXXXXXXX
+;; XXXXXXXXXXXXXXXXXXXXXXXX
+;;
+;;
+;;
+;; XXXXXXXXXXXXXXXXXXXXXXXX
+;; XXXXXXXXXXXXXXXXXXXXXXXX
+;; XXXXXXXXXXXXXXXXXXXXXXXX
+;;
+;; The blocks of X's represent rectangles filled with a light gray color.
+;; Each rectangle extends all the way across the page.
+;;
+;; The height, in lines, of each rectangle is controlled by
+;; the variable `ps-zebra-stripe-height', which is 3 by default.
+;; The distance between stripes equals the height of a stripe.
+;;
+;; The variable `ps-zebra-stripes' controls whether to print zebra stripes.
+;; Non-nil means yes, nil means no. The default is nil.
+;;
+;; The variable `ps-zebra-color' controls the zebra stripes gray scale or RGB
+;; color. It should be a float number between 0.0 (black color) and 1.0 (white
+;; color), a string which is a color name, or a list of 3 numbers which
+;; corresponds to the Red Green Blue color scale.
+;; The default is 0.95 (or "gray95", or '(0.95 0.95 0.95)).
+;;
+;; See also section How Ps-Print Has A Text And/Or Image On Background.
+;;
+;;
+;; Hooks
+;; -----
+;;
+;; ps-print has the following hook variables:
+;;
+;; `ps-print-hook'
+;; It is evaluated once before any printing process. This is the right
+;; place to initialize ps-print global data.
+;; For an example, see section Adding a New Font Family.
+;;
+;; `ps-print-begin-sheet-hook'
+;; It is evaluated on each beginning of sheet of paper.
+;; If `ps-n-up-printing' is equal to 1, `ps-print-begin-page-hook' is never
+;; evaluated.
+;;
+;; `ps-print-begin-page-hook'
+;; It is evaluated on each beginning of page, except in the beginning
+;; of page that `ps-print-begin-sheet-hook' is evaluated.
+;;
+;; `ps-print-begin-column-hook'
+;; It is evaluated on each beginning of column, except in the beginning
+;; of column that `ps-print-begin-page-hook' is evaluated or that
+;; `ps-print-begin-sheet-hook' is evaluated.
+;;
+;;
+;; Font Managing
+;; -------------
+;;
+;; ps-print now knows rather precisely some fonts: the variable
+;; `ps-font-info-database' contains information for a list of font families
+;; (currently mainly `Courier' `Helvetica' `Times' `Palatino' `Helvetica-Narrow'
+;; `NewCenturySchlbk'). Each font family contains the font names for standard,
+;; bold, italic and bold-italic characters, a reference size (usually 10) and
+;; the corresponding line height, width of a space and average character width.
+;;
+;; The variable `ps-font-family' determines which font family is to be used for
+;; ordinary text. If its value does not correspond to a known font family, an
+;; error message is printed into the `*Messages*' buffer, which lists the
+;; currently available font families.
+;;
+;; The variable `ps-font-size' determines the size (in points) of the font for
+;; ordinary text, when generating PostScript. Its value is a float or a cons of
+;; floats which has the following form:
+;;
+;; (LANDSCAPE-SIZE . PORTRAIT-SIZE)
+;;
+;; Similarly, the variable `ps-header-font-family' determines which font family
+;; is to be used for text in the header.
+;;
+;; The variable `ps-header-font-size' determines the font size, in points, for
+;; text in the header (similar to `ps-font-size').
+;;
+;; The variable `ps-header-title-font-size' determines the font size, in points,
+;; for the top line of text in the header (similar to `ps-font-size').
+;;
+;;
+;; Adding a New Font Family
+;; ------------------------
+;;
+;; To use a new font family, you MUST first teach ps-print
+;; this font, i.e., add its information to `ps-font-info-database',
+;; otherwise ps-print cannot correctly place line and page breaks.
+;;
+;; For example, assuming `Helvetica' is unknown,
+;; you first need to do the following ONLY ONCE:
+;;
+;; - create a new buffer
+;; - generate the PostScript image to a file (C-u M-x ps-print-buffer)
+;; - open this file and find the line:
+;; `% 3 cm 20 cm moveto 10 /Courier ReportFontInfo showpage'
+;; - delete the leading `%' (which is the PostScript comment character)
+;; - replace in this line `Courier' by the new font (say `Helvetica')
+;; to get the line:
+;; `3 cm 20 cm moveto 10 /Helvetica ReportFontInfo showpage'
+;; - send this file to the printer (or to ghostscript).
+;; You should read the following on the output page:
+;;
+;; For Helvetica 10 point, the line height is 11.56, the space width is 2.78
+;; and a crude estimate of average character width is 5.09243
+;;
+;; - Add these values to the `ps-font-info-database':
+;; (setq ps-font-info-database
+;; (append
+;; '((Helvetica ; the family key
+;; (fonts (normal . "Helvetica")
+;; (bold . "Helvetica-Bold")
+;; (italic . "Helvetica-Oblique")
+;; (bold-italic . "Helvetica-BoldOblique"))
+;; (size . 10.0)
+;; (line-height . 11.56)
+;; (space-width . 2.78)
+;; (avg-char-width . 5.09243)))
+;; ps-font-info-database))
+;; - Now you can use this font family with any size:
+;; (setq ps-font-family 'Helvetica)
+;; - if you want to use this family in another emacs session, you must
+;; put into your `~/.emacs':
+;; (require 'ps-print)
+;; (setq ps-font-info-database (append ...)))
+;; if you don't want to load ps-print, you have to copy the whole value:
+;; (setq ps-font-info-database '(<your stuff> <the standard stuff>))
+;; or, use `ps-print-hook' (see section Hooks):
+;; (add-hook 'ps-print-hook
+;; '(lambda ()
+;; (or (assq 'Helvetica ps-font-info-database)
+;; (setq ps-font-info-database (append ...)))))
+;;
+;; You can create new `mixed' font families like:
+;; (my-mixed-family
+;; (fonts (normal . "Courier-Bold")
+;; (bold . "Helvetica")
+;; (italic . "Zapf-Chancery-MediumItalic")
+;; (bold-italic . "NewCenturySchlbk-BoldItalic")
+;; (w3-table-hack-x-face . "LineDrawNormal"))
+;; (size . 10.0)
+;; (line-height . 10.55)
+;; (space-width . 6.0)
+;; (avg-char-width . 6.0))
+;;
+;; Now you can use your new font family with any size:
+;; (setq ps-font-family 'my-mixed-family)
+;;
+;; Note that on above example the `w3-table-hack-x-face' entry refers to
+;; a face symbol, so when printing this face it'll be used the font
+;; `LineDrawNormal'. If the face `w3-table-hack-x-face' is remapped to
+;; use bold and/or italic attribute, the corresponding entry (bold, italic
+;; or bold-italic) will be used instead of `w3-table-hack-x-face' entry.
+;;
+;; Note also that the font family entry order is irrelevant, so the above
+;; example could also be written:
+;; (my-mixed-family
+;; (size . 10.0)
+;; (fonts (w3-table-hack-x-face . "LineDrawNormal")
+;; (bold . "Helvetica")
+;; (bold-italic . "NewCenturySchlbk-BoldItalic")
+;; (italic . "Zapf-Chancery-MediumItalic")
+;; (normal . "Courier-Bold"))
+;; (avg-char-width . 6.0)
+;; (space-width . 6.0)
+;; (line-height . 10.55))
+;;
+;; Despite the note above, it is recommended that some convention about
+;; entry order be used.
+;;
+;; You can get information on all the fonts resident in YOUR printer
+;; by uncommenting the line:
+;; % 3 cm 20 cm moveto ReportAllFontInfo showpage
+;;
+;; The PostScript file should be sent to YOUR PostScript printer.
+;; If you send it to ghostscript or to another PostScript printer,
+;; you may get slightly different results.
+;; Anyway, as ghostscript fonts are autoload, you won't get
+;; much font info.
+;;
+;;
+;; How Ps-Print Deals With Faces
+;; -----------------------------
+;;
+;; The ps-print-*-with-faces commands attempt to determine which faces
+;; should be printed in bold or italic, but their guesses aren't
+;; always right. For example, you might want to map colors into faces
+;; so that blue faces print in bold, and red faces in italic.
+;;
+;; It is possible to force ps-print to consider specific faces bold,
+;; italic or underline, no matter what font they are displayed in, by setting
+;; the variables `ps-bold-faces', `ps-italic-faces' and `ps-underlined-faces'.
+;; These variables contain lists of faces that ps-print should consider bold,
+;; italic or underline; to set them, put code like the following into your
+;; .emacs file:
+;;
+;; (setq ps-bold-faces '(my-blue-face))
+;; (setq ps-italic-faces '(my-red-face))
+;; (setq ps-underlined-faces '(my-green-face))
+;;
+;; Faces like bold-italic that are both bold and italic should go in
+;; *both* lists.
+;;
+;; ps-print keeps internal lists of which fonts are bold and which are
+;; italic; these lists are built the first time you invoke ps-print.
+;; For the sake of efficiency, the lists are built only once; the same
+;; lists are referred in later invocations of ps-print.
+;;
+;; Because these lists are built only once, it's possible for them to
+;; get out of sync, if a face changes, or if new faces are added. To
+;; get the lists back in sync, you can set the variable
+;; `ps-build-face-reference' to t, and the lists will be rebuilt the
+;; next time ps-print is invoked. If you need that the lists always be
+;; rebuilt when ps-print is invoked, set the variable
+;; `ps-always-build-face-reference' to t.
+;;
+;; If you need to print without worrying about face background color, set the
+;; variable `ps-use-face-background' which specifies if face background should
+;; be used. Valid values are:
+;;
+;; t always use face background color.
+;; nil never use face background color.
+;; (face...) list of faces whose background color will be used.
+;;
+;; Any other value will be treated as t.
+;; The default value is t.
+;;
+;;
+;; How Ps-Print Deals With Color
+;; -----------------------------
+;;
+;; ps-print detects faces with foreground and background colors
+;; defined and embeds color information in the PostScript image.
+;; The default foreground and background colors are defined by the
+;; variables `ps-default-fg' and `ps-default-bg'.
+;; On black-and-white printers, colors are displayed in gray scale.
+;; To turn off color output, set `ps-print-color-p' to nil.
+;;
+;;
+;; How Ps-Print Maps Faces
+;; -----------------------
+;;
+;; As ps-print uses PostScript to print buffers, it is possible to have
+;; other attributes associated with faces. So the new attributes used
+;; by ps-print are:
+;;
+;; strikeout - like underline, but the line is in middle of text.
+;; overline - like underline, but the line is over the text.
+;; shadow - text will have a shadow.
+;; box - text will be surrounded by a box.
+;; outline - print characters as hollow outlines.
+;;
+;; See the documentation for `ps-extend-face'.
+;;
+;; Let's, for example, remap `font-lock-keyword-face' to another foreground
+;; color and bold attribute:
+;;
+;; (ps-extend-face '(font-lock-keyword-face "RoyalBlue" nil bold) 'MERGE)
+;;
+;; If you want to use a new face, define it first with `defface',
+;; and then call `ps-extend-face' to specify how to print it.
+;;
+;;
+;; How Ps-Print Has A Text And/Or Image On Background
+;; --------------------------------------------------
+;;
+;; ps-print can print texts and/or EPS PostScript images on background; it is
+;; possible to define the following text attributes: font name, font size,
+;; initial position, angle, gray scale and pages to print.
+;;
+;; It has the following EPS PostScript images attributes: file name containing
+;; the image, initial position, X and Y scales, angle and pages to print.
+;;
+;; See documentation for `ps-print-background-text' and
+;; `ps-print-background-image'.
+;;
+;; For example, if we wish to print text "preliminary" on all pages and text
+;; "special" on page 5 and from page 11 to page 17, we could specify:
+;;
+;; (setq ps-print-background-text
+;; '(("preliminary")
+;; ("special"
+;; "LeftMargin" "BottomMargin PrintHeight add" ; X and Y position
+;; ; (upper left corner)
+;; nil nil nil
+;; "PrintHeight neg PrintPageWidth atan" ; angle
+;; 5 (11 . 17)) ; page list
+;; ))
+;;
+;; Similarly, we could print image "~/images/EPS-image1.ps" on all pages and
+;; image "~/images/EPS-image2.ps" on page 5 and from page 11 to page 17, we
+;; specify:
+;;
+;; (setq ps-print-background-image
+;; '(("~/images/EPS-image1.ps"
+;; "LeftMargin" "BottomMargin") ; X and Y position (lower left corner)
+;; ("~/images/EPS-image2.ps"
+;; "LeftMargin" "BottomMargin PrintHeight 2 div add" ; X and Y position
+;; ; (upper left corner)
+;; nil nil nil
+;; 5 (11 . 17)) ; page list
+;; ))
+;;
+;; If it is not possible to read (or does not exist) an image file, that file
+;; is ignored.
+;;
+;; The printing order is:
+;;
+;; 1. Print background color
+;; 2. Print zebra stripes
+;; 3. Print background texts that it should be on all pages
+;; 4. Print background images that it should be on all pages
+;; 5. Print background texts only for current page (if any)
+;; 6. Print background images only for current page (if any)
+;; 7. Print header
+;; 8. Print buffer text (with faces, if specified) and line number
+;;
+;;
+;; Utilities
+;; ---------
+;;
+;; Some tools are provided to help you customize your font setup.
+;;
+;; `ps-setup' returns (some part of) the current setup.
+;;
+;; To avoid wrapping too many lines, you may want to adjust the
+;; left and right margins and the font size. On UN*X systems, do:
+;; pr -t file | awk '{printf "%3d %s\n", length($0), $0}' | sort -r | head
+;; to determine the longest lines of your file.
+;; Then, the command `ps-line-lengths' will give you the correspondence
+;; between a line length (number of characters) and the maximum font
+;; size which doesn't wrap such a line with the current ps-print setup.
+;;
+;; The commands `ps-nb-pages-buffer' and `ps-nb-pages-region' display
+;; the correspondence between a number of pages and the maximum font
+;; size which allow the number of lines of the current buffer or of
+;; its current region to fit in this number of pages.
+;;
+;; NOTE: line folding is not taken into account in this process and could
+;; change the results.
+;;
+;; The command `ps-print-customize' activates a customization buffer for
+;; ps-print options.
+;;
+;;
+;; New since version 1.5
+;; ---------------------
+;;
+;; Color output capability.
+;; Automatic detection of font attributes (bold, italic).
+;; Configurable headers with page numbers.
+;; Slightly faster.
+;; Support for different paper sizes.
+;; Better conformance to PostScript Document Structure Conventions.

+;; Known bugs and limitations of ps-print
+;; --------------------------------------
+;;
+;; Although color printing will work in XEmacs 19.12, it doesn't work
+;; well; in particular, bold or italic fonts don't print in the right
+;; background color.
+;;
+;; Invisible properties aren't correctly ignored in XEmacs 19.12.
+;;
+;; Automatic font-attribute detection doesn't work well, especially
+;; with hilit19 and older versions of get-create-face. Users having
+;; problems with auto-font detection should use the lists
+;; `ps-italic-faces', `ps-bold-faces' and `ps-underlined-faces' and/or
+;; turn off automatic detection by setting `ps-auto-font-detect' to nil.
+;;
+;; Automatic font-attribute detection doesn't work with XEmacs 19.12
+;; in tty mode; use the lists `ps-italic-faces', `ps-bold-faces' and
+;; `ps-underlined-faces' instead.
+;;
+;; Still too slow; could use some hand-optimization.
+;;
+;; Default background color isn't working.
+;;
+;; Faces are always treated as opaque.
+;;
+;; Epoch and Emacs 19 not supported. At all.
+;;
+;; Fixed-pitch fonts work better for line folding, but are not required.
+;;
+;; `ps-nb-pages-buffer' and `ps-nb-pages-region' don't take care
+;; of folding lines.
+;;
+;;
+;; Things to change
+;; ----------------
+;;
+;; Avoid page break inside a paragraph.
+;; Add `ps-non-bold-faces' and `ps-non-italic-faces' (should be easy).
+;; Improve the memory management for big files (hard?).
+;; `ps-nb-pages-buffer' and `ps-nb-pages-region' should take care
+;; of folding lines.
