;; 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 or Lucid Emacs, together with a fontifying package such as
-;; font-lock or hilit.
+;; 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
;; The variable `ps-printer-name' determines the name of a local printer for
;; printing PostScript files.
;;
+;; The variable `ps-printer-name-option' determines the option used by some
+;; utilities to indicate the printer name, it's used only when
+;; `ps-printer-name' is a non-empty string. If you're using lpr utility to
+;; print, for example, `ps-printer-name-option' should be set to "-P".
+;;
;; 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'.
+;; `printer-name'. `ps-printer-name-option' tries to guess which system
+;; Emacs is running and takes its initial value in accordance with this
+;; guess.
;;
;; 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.
;;
+;; The variable `ps-manual-feed' indicates if the printer will manually feed
+;; paper. If it's nil, automatic feeding takes place. If it's non-nil, manual
+;; feeding takes place. The default is nil (automatic feeding).
+;;
+;; 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-printer-name-option', `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-landscape-mode' determines the orientation
-;; of the printing on the page:
-;; nil means `portrait' mode, non-nil means `landscape' mode.
+;; 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'.
+;;
+;; If variable `ps-warn-paper-type' is nil, it's *not* given an error if
+;; PostScript printer doesn't have a paper with the size indicated by
+;; `ps-paper-type', instead it uses the default paper size. If variable
+;; `ps-warn-paper-type' is non-nil, it's given an error if PostScript printer
+;; doesn't have a paper with the size indicated by `ps-paper-type'. It's used
+;; when `ps-spool-config' is set to `setpagedevice' (see section Duplex
+;; Printers). The default value is non-nil (it gives an error).
+;;
+;; 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.
+;;
+;; The variable `ps-selected-pages' specifies which pages to print. If it's
+;; nil, all pages are printed. If it's a list, the list element may be an
+;; integer or a cons cell (FROM . TO) designating FROM page to TO page; any
+;; invalid element is ignored, that is, an integer lesser than one or if FROM
+;; is greater than TO. Otherwise, it's treated as nil. The default value is
+;; nil (print all pages). After ps-print processing `ps-selected-pages' is set
+;; to nil. But the latest `ps-selected-pages' is saved in
+;; `ps-last-selected-pages' (see it for documentation). So you can restore the
+;; latest selected pages by using `ps-last-selected-pages' or by calling
+;; `ps-restore-selected-pages' command (see it for documentation).
+;;
+;; The variable `ps-even-or-odd-pages' specifies if it prints even/odd pages.
+;;
+;; Valid values are:
+;;
+;; nil print all pages.
+;;
+;; even print only even pages.
+;;
+;; odd print only odd pages.
+;;
+;; Any other value is treated as nil. The default value is nil.
;;
;;
;; Horizontal layout
;; To print only one header at the top of each page,
;; set `ps-print-only-one-header' to t.
;;
+;; To switch headers, set `ps-switch-header' to:
+;;
+;; nil Never switch headers.
+;;
+;; t Always switch headers.
+;;
+;; duplex Switch headers only when duplexing is on, that is, when
+;; `ps-spool-duplex' is non-nil (see Duplex Printers).
+;;
+;; Any other value is treated as t. The default value is `duplex'.
+;;
;; 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).
;; 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.

;; 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 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
+;;
+;; As an example for `ps-user-defined-prologue' setting:
+;;
+;; ;; Setting for HP PostScript printer
+;; (setq ps-user-defined-prologue
+;; (concat "<</DeferredMediaSelection true /PageSize [612 792] "
+;; "/MediaPosition 2 /MediaType (Plain)>> setpagedevice"))
+;;
+;;
+;; 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
;; ---------------
;;
;; See ps-mule.el for documentation.
;;
-;; See ps-print-def.el for definition.
-;;
;;
;; 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-stripe-height' inclusive.
+;;
+;; The default value is 1, so the line number of the first line of each interval
+;; is printed.
+;;
;;
;; Zebra Stripes
;; -------------
;; 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-gray' controls the zebra stripes gray scale.
-;; It should be a float number between 0.0 (black color) and 1.0 (white color).
-;; The default is 0.95.
+;; 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)).
+;;
+;; The variable `ps-zebra-stripe-follow' specifies if zebra stripe should
+;; continue on next page or restart on each page. If `ps-zebra-stripe-follow'
+;; is nil, zebra stripe is restarted on each page. If `ps-zebra-stripe-follow'
+;; is non-nil, zebra stripe continues on next page. Visually, we have:
+;;
+;; `ps-zebra-stripe-follow' `ps-zebra-stripe-follow'
+;; is nil is non-nil

+;;
+;; 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
;; -----------------------------
;; 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.
;;
;;
;;
;; The printing order is:
;;
-;; 1. Print zebra stripes
-;; 2. Print background texts that it should be on all pages
-;; 3. Print background images that it should be on all pages
-;; 4. Print background texts only for current page (if any)
-;; 5. Print background images only for current page (if any)
-;; 6. Print header
-;; 7. Print buffer text (with faces, if specified) and line number
+;; 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)
