;; --------------
;;
-;; This package provides printing of Emacs buffers on PostScript
-;; printers; the buffer's bold and italic text attributes are

+;; 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
;; --------------
;;
-;; The Commands
-;;

;;
;; ps-print-buffer
;; 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
;; 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
;; 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-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.
+;; 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 lignes in landscape mode.
-;; The margins represent margins in the printed paper:
-;; the top margin is the margin between the top of the page
+;;
+;; 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.
+;; 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
+;; - (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
+;; - 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
;; Headers
;; -------
;;
-;; Ps-print can print headers at the top of each column; 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 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').
;;
;; 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
+;; 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
;;
;; 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.
+;;
+;; For more information about PostScript, see:
+;; 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.
-;; Don't forget to set `ps-lpr-switches' to select duplex printing
-;; for your printer.
+;; 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:
;;
-;;
-;; Font managing
+;; 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
;; -------------
;;
-;; 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.
-;;
-;; 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.
-;; The variable `ps-header-title-font-size' determines the font size,
-;; in points, for the top line of text in the header.
-;;
-;;
-;; Adding a new font family
+;; 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,

+;; 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
;; ------------------------

-;; For example, assuming `Helvetica' is unkown,
+;; 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)
+;; - 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'
;;
;; - Add these values to the `ps-font-info-database':
;; (setq ps-font-info-database
-;; (append
-;; '((Helvetica ; the family name
-;; "Helvetica" "Helvetica-Bold" "Helvetica-Oblique" "Helvetica-BoldOblique"
-;; 10.0 11.56 2.78 5.09243))
-;; ps-font-info-database))
+;; (append
+;; '((Helvetica ; the family key

+;; (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
;; (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, if you can wait until the `ps-print-hook' is implemented, do:
-;; (add-hook 'ps-print-hook '(setq ps-font-info-database (append ...)))
-;; This does not work yet, since there is no `ps-print-hook' yet.
+;; 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
-;; "Courier-Bold" "Helvetica"
-;; "Zapf-Chancery-MediumItalic" "NewCenturySchlbk-BoldItalic"
-;; 10.0 10.55 6.0 6.0)
+;; (my-mixed-family
+;; (fonts (normal . "Courier-Bold")

+;; (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,
+;; The PostScript file should be sent to YOUR PostScript printer.
+;; If you send it to ghostscript or to another PostScript printer,

;; 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 or
-;; italic, no matter what font they are displayed in, by setting the
-;; variables `ps-bold-faces' and `ps-italic-faces'. These variables
-;; contain lists of faces that ps-print should consider bold or
-;; italic; to set them, put code like the following into your .emacs
-;; file:
+;; 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-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

;; 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.
+;; 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
+;; 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 grayscale.
+;; 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
+;;
+;;
