;; 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
+;; 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.
;;
;; Using ps-print
;; --------------
;;
-;; The Commands
-;;
-;; Ps-print provides eight commands for generating PostScript images
+;; ps-print provides eight commands for generating PostScript images
;; of Emacs buffers:
;;
;; ps-print-buffer
;; 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
+;; 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
;; 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.
;;
;;
;; The Page Layout
;; Headers
;; -------
;;
-;; Ps-print can print headers at the top of each column or at the top
+;; 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
;; 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

+;;
;; 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:
+;;
+;; 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
;;
;; 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
+;; 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
+;; 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.
+;; 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
+;; nil No ASCII encoding. Any character is printed according the
;; current font.
;;
;; Any other value is treated as nil.
;; Characters TAB, NEWLINE and FORMFEED are always treated by ps-print engine.
;;
;;
-;; Printing Multi-Byte Buffer
+;; Printing Multi-byte Buffer
;; --------------------------
;;
-;; ps-print can print multi-byte buffer.
-;;
-;; If you are using only Latin-1 characters, you don't need to do anything else.
-;;
-;; If you have a japanese or korean PostScript printer, you can print ASCII,
-;; Latin-1, Japanese (JISX0208, and JISX0201-Kana) and Korean characters by
-;; setting:
-;;
-;; (setq ps-mule-font-info-database ps-mule-font-info-database-ps)
-;;
-;; At present, it was not tested the korean characters printing. If you have
-;; a korean PostScript printer, please verify it.
+;; See ps-mule.el for documentation.
;;
-;; If you use any other kind of character, you need to install intlfonts-1.1.
-;; So you can print using BDF fonts contained in intlfonts-1.1. To print using
-;; BDF fonts, do the following settings:
-;;
-;; (1) Set the variable `bdf-directory-list' appropriately (see bdf.el for
-;; documentation of this variable).
-;;
-;; (2) (setq ps-mule-font-info-database-ps ps-mule-font-info-database-bdf)
+;; See ps-print-def.el for definition.
;;
;;
;; Line Number
;; 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.
+;;
;; See also section How Ps-Print Has A Text And/Or Image On Background.

;; 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.
