;; 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.
;;
+;; 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

+;;
+;; 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' determine 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 Page Layout
;; 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:
;; 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
+;;
+;;
;; 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
+;; 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.
;;
-;;
-;; Font managing
+;;
+;; 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).
+;;
+;;
+;; 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.
+;;
+;; 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-page-hook'
+;; It is evaluated on each real beginning of page, that is, ps-print
+;; considers each beginning of column as a beginning of page, and a real
+;; beginning of page is when the beginning of column coincides with a
+;; paper change on your printer.
+;;
+;; `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.
+;;
+;;
+;; 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.
-;;
-;; 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.

+;;
+;; The variable `ps-header-title-font-size' determines the font size, in points,

+;;
+;;
+;; Adding a New Font Family
;; ------------------------
;;
;; To use a new font family, you MUST first teach ps-print
-;; this font, ie add its information to `ps-font-info-database',
+;; 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 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
+;; (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
;; (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 () (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")
+;; (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,
+;; 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.
;; 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
+;; 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.
;; 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.
;;
;;
;; 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'.
;; 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 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
+;;
