51 ;; This package provides printing of Emacs buffers on PostScript
52 ;; printers; the buffer's bold and italic text attributes are
53 ;; preserved in the printer output. ps-print is intended for use with
54 ;; Emacs 19 or Lucid Emacs, together with a fontifying package such as
55 ;; font-lock or hilit.
57 ;; ps-print uses the same face attributes defined through font-lock or hilit
58 ;; to print a PostScript file, but some faces are better seeing on the screen
59 ;; than on paper, specially when you have a black/white PostScript printer.
61 ;; ps-print allows a remap of face to another one that it is better to print,
62 ;; for example, the face font-lock-comment-face (if you are using font-lock)
63 ;; could have bold or italic attribute when printing, besides foreground color.
64 ;; This remap improves printing look (see How Ps-Print Maps Faces).
70 ;; ps-print provides eight commands for generating PostScript images
74 ;; ps-print-buffer-with-faces
76 ;; ps-print-region-with-faces
78 ;; ps-spool-buffer-with-faces
80 ;; ps-spool-region-with-faces
82 ;; These commands all perform essentially the same function: they
83 ;; generate PostScript images suitable for printing on a PostScript
84 ;; printer or displaying with GhostScript. These commands are
85 ;; collectively referred to as "ps-print- commands".
87 ;; The word "print" or "spool" in the command name determines when the
88 ;; PostScript image is sent to the printer:
90 ;; print - The PostScript image is immediately sent to the
93 ;; spool - The PostScript image is saved temporarily in an
94 ;; Emacs buffer. Many images may be spooled locally
95 ;; before printing them. To send the spooled images
96 ;; to the printer, use the command `ps-despool'.
98 ;; The spooling mechanism was designed for printing lots of small
99 ;; files (mail messages or netnews articles) to save paper that would
100 ;; otherwise be wasted on banner pages, and to make it easier to find
101 ;; your output at the printer (it's easier to pick up one 50-page
102 ;; printout than to find 50 single-page printouts).
104 ;; ps-print has a hook in the `kill-emacs-hook' so that you won't
105 ;; accidentally quit from Emacs while you have unprinted PostScript
106 ;; waiting in the spool buffer. If you do attempt to exit with
107 ;; spooled PostScript, you'll be asked if you want to print it, and if
108 ;; you decline, you'll be asked to confirm the exit; this is modeled
109 ;; on the confirmation that Emacs uses for modified buffers.
111 ;; The word "buffer" or "region" in the command name determines how
112 ;; much of the buffer is printed:
114 ;; buffer - Print the entire buffer.
116 ;; region - Print just the current region.
118 ;; The -with-faces suffix on the command name means that the command
119 ;; will include font, color, and underline information in the
120 ;; PostScript image, so the printed image can look as pretty as the
121 ;; buffer. The ps-print- commands without the -with-faces suffix
122 ;; don't include font, color, or underline information; images printed
123 ;; with these commands aren't as pretty, but are faster to generate.
125 ;; Two ps-print- command examples:
127 ;; ps-print-buffer - print the entire buffer,
128 ;; without font, color, or
129 ;; underline information, and
130 ;; send it immediately to the
133 ;; ps-spool-region-with-faces - print just the current region;
134 ;; include font, color, and
135 ;; underline information, and
136 ;; spool the image in Emacs to
137 ;; send to the printer later.
143 ;; To print your buffer, type
145 ;; M-x ps-print-buffer
147 ;; or substitute one of the other seven ps-print- commands. The
148 ;; command will generate the PostScript image and print or spool it as
149 ;; specified. By giving the command a prefix argument
151 ;; C-u M-x ps-print-buffer
153 ;; it will save the PostScript image to a file instead of sending it
154 ;; to the printer; you will be prompted for the name of the file to
155 ;; save the image to. The prefix argument is ignored by the commands
156 ;; that spool their images, but you may save the spooled images to a
157 ;; file by giving a prefix argument to `ps-despool':
159 ;; C-u M-x ps-despool
161 ;; When invoked this way, `ps-despool' will prompt you for the name of
162 ;; the file to save to.
164 ;; Any of the `ps-print-' commands can be bound to keys; I recommend
165 ;; binding `ps-spool-buffer-with-faces', `ps-spool-region-with-faces',
166 ;; and `ps-despool'. Here are the bindings I use on my Sun 4 keyboard:
168 ;; (global-set-key 'f22 'ps-spool-buffer-with-faces) ;f22 is prsc
169 ;; (global-set-key '(shift f22) 'ps-spool-region-with-faces)
170 ;; (global-set-key '(control f22) 'ps-despool)
173 ;; The Printer Interface
174 ;; ---------------------
176 ;; The variables `ps-lpr-command' and `ps-lpr-switches' determine what
177 ;; command is used to send the PostScript images to the printer, and
178 ;; what arguments to give the command. These are analogous to
179 ;; `lpr-command' and `lpr-switches'.
181 ;; Make sure that they contain appropriate values for your system;
182 ;; see the usage notes below and the documentation of these variables.
184 ;; The variable `ps-printer-name' determine the name of a local printer for
185 ;; printing PostScript files.
187 ;; NOTE: `ps-lpr-command' and `ps-lpr-switches' take their initial values
188 ;; from the variables `lpr-command' and `lpr-switches'. If you have
189 ;; `lpr-command' set to invoke a pretty-printer such as `enscript',
190 ;; then ps-print won't work properly. `ps-lpr-command' must name
191 ;; a program that does not format the files it prints.
192 ;; `ps-printer-name' takes its initial value from the variable
199 ;; All dimensions are floats in PostScript points.
200 ;; 1 inch == 2.54 cm == 72 points
201 ;; 1 cm == (/ 1 2.54) inch == (/ 72 2.54) points
203 ;; The variable `ps-paper-type' determines the size of paper ps-print
204 ;; formats for; it should contain one of the symbols:
205 ;; `a4' `a3' `letter' `legal' `letter-small' `tabloid'
206 ;; `ledger' `statement' `executive' `a4small' `b4' `b5'
208 ;; The variable `ps-landscape-mode' determines the orientation
209 ;; of the printing on the page:
210 ;; nil means `portrait' mode, non-nil means `landscape' mode.
211 ;; There is no oblique mode yet, though this is easy to do in ps.
213 ;; In landscape mode, the text is NOT scaled: you may print 70 lines
214 ;; in portrait mode and only 50 lignes in landscape mode.
215 ;; The margins represent margins in the printed paper:
216 ;; the top margin is the margin between the top of the page
217 ;; and the printed header, whatever the orientation is.
219 ;; The variable `ps-number-of-columns' determines the number of columns
220 ;; both in landscape and portrait mode.
222 ;; - (the standard) one column portrait mode
223 ;; - (my favorite) two columns landscape mode (which spares trees)
225 ;; - one column landscape mode for files with very long lines.
226 ;; - multi-column portrait or landscape mode
232 ;; The horizontal layout is determined by the variables
233 ;; `ps-left-margin' `ps-inter-column' `ps-right-margin'
236 ;; ------------------------------------------
238 ;; | lm | text | ic | text | ic | text | rm |
240 ;; ------------------------------------------
242 ;; If `ps-number-of-columns' is 1, `ps-inter-column' is not relevant.
243 ;; Usually, lm = rm > 0 and ic = lm
244 ;; If (ic < 0), the text of adjacent columns can overlap.
250 ;; The vertical layout is determined by the variables
251 ;; `ps-bottom-margin' `ps-top-margin' `ps-header-offset'
254 ;; |--------| |--------|
256 ;; |--------| |--------|
260 ;; |--------| or | text |
264 ;; |--------| |--------|
266 ;; |--------| |--------|
268 ;; If `ps-print-header' is nil, `ps-header-offset' is not relevant.
269 ;; The margins represent margins in the printed paper:
270 ;; the top margin is the margin between the top of the page
271 ;; and the printed header, whatever the orientation is.
277 ;; ps-print can print headers at the top of each column or at the top
278 ;; of each page; the default headers contain the following four items:
279 ;; on the left, the name of the buffer and, if the buffer is visiting
280 ;; a file, the file's directory; on the right, the page number and
281 ;; date of printing. The default headers look something like this:
284 ;; /home/jct/emacs-lisp/ps/new 94/12/31
286 ;; When printing on duplex printers, left and right are reversed so
287 ;; that the page numbers are toward the outside (cf. `ps-spool-duplex').
289 ;; Headers are configurable:
290 ;; To turn them off completely, set `ps-print-header' to nil.
291 ;; To turn off the header's gaudy framing box,
292 ;; set `ps-print-header-frame' to nil.
294 ;; To print only one header at the top of each page,
295 ;; set `ps-print-only-one-header' to t.
297 ;; The font family and size of text in the header are determined
298 ;; by the variables `ps-header-font-family', `ps-header-font-size' and
299 ;; `ps-header-title-font-size' (see below).
301 ;; The variable `ps-header-line-pad' determines the portion of a header
302 ;; title line height to insert between the header frame and the text
303 ;; it contains, both in the vertical and horizontal directions:
304 ;; .5 means half a line.
306 ;; Page numbers are printed in `n/m' format, indicating page n of m pages;
307 ;; to omit the total page count and just print the page number,
308 ;; set `ps-show-n-of-n' to nil.
310 ;; The amount of information in the header can be changed by changing
311 ;; the number of lines. To show less, set `ps-header-lines' to 1, and
312 ;; the header will show only the buffer name and page number. To show
313 ;; more, set `ps-header-lines' to 3, and the header will show the time of
314 ;; printing below the date.
316 ;; To change the content of the headers, change the variables
317 ;; `ps-left-header' and `ps-right-header'.
318 ;; These variables are lists, specifying top-to-bottom the text
319 ;; to display on the left or right side of the header.
320 ;; Each element of the list should be a string or a symbol.
321 ;; Strings are inserted directly into the PostScript arrays,
322 ;; and should contain the PostScript string delimiters '(' and ')'.
324 ;; Symbols in the header format lists can either represent functions
325 ;; or variables. Functions are called, and should return a string to
326 ;; show in the header. Variables should contain strings to display in
327 ;; the header. In either case, function or variable, the PostScript
328 ;; string delimiters are added by ps-print, and should not be part of
329 ;; the returned value.
331 ;; Here's an example: say we want the left header to display the text
337 ;; where we have a function to return "Moe"
339 ;; (defun moe-func ()
342 ;; a variable specifying "Larry"
344 ;; (setq larry-var "Larry")
346 ;; and a literal for "Curly". Here's how `ps-left-header' should be
349 ;; (setq ps-left-header (list 'moe-func 'larry-var "(Curly)"))
351 ;; Note that Curly has the PostScript string delimiters inside his
352 ;; quotes -- those aren't misplaced lisp delimiters!
354 ;; Without them, PostScript would attempt to call the undefined
355 ;; function Curly, which would result in a PostScript error.
357 ;; Since most printers don't report PostScript errors except by
358 ;; aborting the print job, this kind of error can be hard to track down.
360 ;; Consider yourself warned!
363 ;; PostScript Prologue Header
364 ;; --------------------------
366 ;; It is possible to add PostScript prologue header comments besides that
367 ;; ps-print generates by setting the variable `ps-print-prologue-header'.
369 ;; `ps-print-prologue-header' may be a string or a symbol function which
370 ;; returns a string. Note that this string is inserted on PostScript prologue
371 ;; header section which is used to define some document characteristic through
372 ;; PostScript special comments, like "%%Requirements: jog\n".
374 ;; By default `ps-print-prologue-header' is nil.
376 ;; ps-print always inserts the %%Requirements: comment, so if you need to insert
377 ;; more requirements put them first in `ps-print-prologue-header' using the
378 ;; "%%+" comment. For example, if you need to set numcopies to 3 and jog on
379 ;; requirements and set %%LanguageLevel: to 2, do:
381 ;; (setq ps-print-prologue-header
382 ;; "%%+ numcopies(3) jog\n%%LanguageLevel: 2\n")
384 ;; The duplex requirement is inserted by ps-print (see section Duplex Printers).
386 ;; Do not forget to terminate the string with "\n".
388 ;; For more information about PostScript document comments, see:
389 ;; PostScript Language Reference Manual (2nd edition)
390 ;; Adobe Systems Incorporated
391 ;; Appendix G: Document Structuring Conventions -- Version 3.0
397 ;; If you have a duplex-capable printer (one that prints both sides of
398 ;; the paper), set `ps-spool-duplex' to t.
399 ;; ps-print will insert blank pages to make sure each buffer starts
400 ;; on the correct side of the paper.
401 ;; Don't forget to set `ps-lpr-switches' to select duplex printing
405 ;; Control And 8-bit Characters
406 ;; ----------------------------
408 ;; The variable `ps-print-control-characters' specifies whether you want to see
409 ;; a printable form for control and 8-bit characters, that is, instead of
410 ;; sending, for example, a ^D (\004) to printer, it is sent the string "^D".
412 ;; Valid values for `ps-print-control-characters' are:
414 ;; 8-bit This is the value to use when you want an ASCII encoding of
415 ;; any control or non-ASCII character. Control characters are
416 ;; encoded as "^D", and non-ASCII characters have an
419 ;; control-8-bit This is the value to use when you want an ASCII encoding of
420 ;; any control character, whether it is 7 or 8-bit.
421 ;; European 8-bits accented characters are printed according
424 ;; control Only ASCII control characters have an ASCII encoding.
425 ;; European 8-bits accented characters are printed according
428 ;; nil No ASCII encoding. Any character is printed according the
431 ;; Any other value is treated as nil.
433 ;; The default is `control-8-bit'.
435 ;; Characters TAB, NEWLINE and FORMFEED are always treated by ps-print engine.
438 ;; Printing Multi-byte Buffer
439 ;; --------------------------
441 ;; See ps-mule.el for documentation.
447 ;; The variable `ps-line-number' specifies whether to number each line;
448 ;; non-nil means do so. The default is nil (don't number each line).
454 ;; Zebra stripes are a kind of background that appear "underneath" the text
455 ;; and can make the text easier to read. They look like this:
457 ;; XXXXXXXXXXXXXXXXXXXXXXXX
458 ;; XXXXXXXXXXXXXXXXXXXXXXXX
459 ;; XXXXXXXXXXXXXXXXXXXXXXXX
463 ;; XXXXXXXXXXXXXXXXXXXXXXXX
464 ;; XXXXXXXXXXXXXXXXXXXXXXXX
465 ;; XXXXXXXXXXXXXXXXXXXXXXXX
467 ;; The blocks of X's represent rectangles filled with a light gray color.
468 ;; Each rectangle extends all the way across the page.
470 ;; The height, in lines, of each rectangle is controlled by
471 ;; the variable `ps-zebra-stripe-height', which is 3 by default.
472 ;; The distance between stripes equals the height of a stripe.
474 ;; The variable `ps-zebra-stripes' controls whether to print zebra stripes.
475 ;; Non-nil means yes, nil means no. The default is nil.
477 ;; See also section How Ps-Print Has A Text And/Or Image On Background.
483 ;; ps-print has the following hook variables:
486 ;; It is evaluated once before any printing process. This is the right
487 ;; place to initialize ps-print global data.
488 ;; For an example, see section Adding a New Font Family.
490 ;; `ps-print-begin-page-hook'
491 ;; It is evaluated on each real beginning of page, that is, ps-print
492 ;; considers each beginning of column as a beginning of page, and a real
493 ;; beginning of page is when the beginning of column coincides with a
494 ;; paper change on your printer.
496 ;; `ps-print-begin-column-hook'
497 ;; It is evaluated on each beginning of column, except in the beginning
498 ;; of column that `ps-print-begin-page-hook' is evaluated.
504 ;; ps-print now knows rather precisely some fonts:
505 ;; the variable `ps-font-info-database' contains information
506 ;; for a list of font families (currently mainly `Courier' `Helvetica'
507 ;; `Times' `Palatino' `Helvetica-Narrow' `NewCenturySchlbk').
508 ;; Each font family contains the font names for standard, bold, italic
509 ;; and bold-italic characters, a reference size (usually 10) and the
510 ;; corresponding line height, width of a space and average character width.
512 ;; The variable `ps-font-family' determines which font family
513 ;; is to be used for ordinary text.
514 ;; If its value does not correspond to a known font family,
515 ;; an error message is printed into the `*Messages*' buffer,
516 ;; which lists the currently available font families.
518 ;; The variable `ps-font-size' determines the size (in points)
519 ;; of the font for ordinary text, when generating PostScript.
520 ;; Its value is a float.
522 ;; Similarly, the variable `ps-header-font-family' determines
523 ;; which font family is to be used for text in the header.
524 ;; The variable `ps-header-font-size' determines the font size,
525 ;; in points, for text in the header.
526 ;; The variable `ps-header-title-font-size' determines the font size,
527 ;; in points, for the top line of text in the header.
530 ;; Adding a New Font Family
531 ;; ------------------------
533 ;; To use a new font family, you MUST first teach ps-print
534 ;; this font, i.e., add its information to `ps-font-info-database',
535 ;; otherwise ps-print cannot correctly place line and page breaks.
537 ;; For example, assuming `Helvetica' is unknown,
538 ;; you first need to do the following ONLY ONCE:
540 ;; - create a new buffer
541 ;; - generate the PostScript image to a file (C-u M-x ps-print-buffer)
542 ;; - open this file and find the line:
543 ;; `% 3 cm 20 cm moveto 10 /Courier ReportFontInfo showpage'
544 ;; - delete the leading `%' (which is the PostScript comment character)
545 ;; - replace in this line `Courier' by the new font (say `Helvetica')
547 ;; `3 cm 20 cm moveto 10 /Helvetica ReportFontInfo showpage'
548 ;; - send this file to the printer (or to ghostscript).
549 ;; You should read the following on the output page:
551 ;; For Helvetica 10 point, the line height is 11.56, the space width is 2.78
552 ;; and a crude estimate of average character width is 5.09243
554 ;; - Add these values to the `ps-font-info-database':
555 ;; (setq ps-font-info-database
557 ;; '((Helvetica ; the family key
558 ;; (fonts (normal . "Helvetica")
559 ;; (bold . "Helvetica-Bold")
560 ;; (italic . "Helvetica-Oblique")
561 ;; (bold-italic . "Helvetica-BoldOblique"))
563 ;; (line-height . 11.56)
564 ;; (space-width . 2.78)
565 ;; (avg-char-width . 5.09243)))
566 ;; ps-font-info-database))
567 ;; - Now you can use this font family with any size:
568 ;; (setq ps-font-family 'Helvetica)
569 ;; - if you want to use this family in another emacs session, you must
570 ;; put into your `~/.emacs':
571 ;; (require 'ps-print)
572 ;; (setq ps-font-info-database (append ...)))
573 ;; if you don't want to load ps-print, you have to copy the whole value:
574 ;; (setq ps-font-info-database '(<your stuff> <the standard stuff>))
575 ;; or, use `ps-print-hook' (see section Hooks):
576 ;; (add-hook 'ps-print-hook
577 ;; '(lambda () (setq ps-font-info-database (append ...))))
579 ;; You can create new `mixed' font families like:
581 ;; (fonts (normal . "Courier-Bold")
582 ;; (bold . "Helvetica")
583 ;; (italic . "Zapf-Chancery-MediumItalic")
584 ;; (bold-italic . "NewCenturySchlbk-BoldItalic")
585 ;; (w3-table-hack-x-face . "LineDrawNormal"))
587 ;; (line-height . 10.55)
588 ;; (space-width . 6.0)
589 ;; (avg-char-width . 6.0))
591 ;; Now you can use your new font family with any size:
592 ;; (setq ps-font-family 'my-mixed-family)
594 ;; Note that on above example the `w3-table-hack-x-face' entry refers to
595 ;; a face symbol, so when printing this face it'll be used the font
596 ;; `LineDrawNormal'. If the face `w3-table-hack-x-face' is remapped to
597 ;; use bold and/or italic attribute, the corresponding entry (bold, italic
598 ;; or bold-italic) will be used instead of `w3-table-hack-x-face' entry.
600 ;; Note also that the font family entry order is irrelevant, so the above
601 ;; example could also be written:
604 ;; (fonts (w3-table-hack-x-face . "LineDrawNormal")
605 ;; (bold . "Helvetica")
606 ;; (bold-italic . "NewCenturySchlbk-BoldItalic")
607 ;; (italic . "Zapf-Chancery-MediumItalic")
608 ;; (normal . "Courier-Bold"))
609 ;; (avg-char-width . 6.0)
610 ;; (space-width . 6.0)
611 ;; (line-height . 10.55))
613 ;; Despite the note above, it is recommended that some convention about
614 ;; entry order be used.
616 ;; You can get information on all the fonts resident in YOUR printer
617 ;; by uncommenting the line:
618 ;; % 3 cm 20 cm moveto ReportAllFontInfo showpage
620 ;; The PostScript file should be sent to YOUR PostScript printer.
621 ;; If you send it to ghostscript or to another PostScript printer,
622 ;; you may get slightly different results.
623 ;; Anyway, as ghostscript fonts are autoload, you won't get
627 ;; How Ps-Print Deals With Faces
628 ;; -----------------------------
630 ;; The ps-print-*-with-faces commands attempt to determine which faces
631 ;; should be printed in bold or italic, but their guesses aren't
632 ;; always right. For example, you might want to map colors into faces
633 ;; so that blue faces print in bold, and red faces in italic.
635 ;; It is possible to force ps-print to consider specific faces bold,
636 ;; italic or underline, no matter what font they are displayed in, by setting
637 ;; the variables `ps-bold-faces', `ps-italic-faces' and `ps-underlined-faces'.
638 ;; These variables contain lists of faces that ps-print should consider bold,
639 ;; italic or underline; to set them, put code like the following into your
642 ;; (setq ps-bold-faces '(my-blue-face))
643 ;; (setq ps-italic-faces '(my-red-face))
644 ;; (setq ps-underlined-faces '(my-green-face))
646 ;; Faces like bold-italic that are both bold and italic should go in
649 ;; ps-print keeps internal lists of which fonts are bold and which are
650 ;; italic; these lists are built the first time you invoke ps-print.
651 ;; For the sake of efficiency, the lists are built only once; the same
652 ;; lists are referred in later invocations of ps-print.
654 ;; Because these lists are built only once, it's possible for them to
655 ;; get out of sync, if a face changes, or if new faces are added. To
656 ;; get the lists back in sync, you can set the variable
657 ;; `ps-build-face-reference' to t, and the lists will be rebuilt the
658 ;; next time ps-print is invoked. If you need that the lists always be
659 ;; rebuilt when ps-print is invoked, set the variable
660 ;; `ps-always-build-face-reference' to t.
663 ;; How Ps-Print Deals With Color
664 ;; -----------------------------
666 ;; ps-print detects faces with foreground and background colors
667 ;; defined and embeds color information in the PostScript image.
668 ;; The default foreground and background colors are defined by the
669 ;; variables `ps-default-fg' and `ps-default-bg'.
670 ;; On black-and-white printers, colors are displayed in grayscale.
671 ;; To turn off color output, set `ps-print-color-p' to nil.
674 ;; How Ps-Print Maps Faces
675 ;; -----------------------
677 ;; As ps-print uses PostScript to print buffers, it is possible to have
678 ;; other attributes associated with faces. So the new attributes used
681 ;; strikeout - like underline, but the line is in middle of text.
682 ;; overline - like underline, but the line is over the text.
683 ;; shadow - text will have a shadow.
684 ;; box - text will be surrounded by a box.
685 ;; outline - print characters as hollow outlines.
687 ;; See the documentation for `ps-extend-face'.
689 ;; Let's, for example, remap font-lock-keyword-face to another foreground color
690 ;; and bold attribute:
692 ;; (ps-extend-face '(font-lock-keyword-face "RoyalBlue" nil bold) 'MERGE)
694 ;; If you want to use a new face, define it first with `defface',
695 ;; and then call `ps-extend-face' to specify how to print it.
698 ;; How Ps-Print Has A Text And/Or Image On Background
699 ;; --------------------------------------------------
701 ;; ps-print can print texts and/or EPS PostScript images on background; it is
702 ;; possible to define the following text attributes: font name, font size,
703 ;; initial position, angle, gray scale and pages to print.
705 ;; It has the following EPS PostScript images attributes: file name containing
706 ;; the image, initial position, X and Y scales, angle and pages to print.
708 ;; See documentation for `ps-print-background-text' and
709 ;; `ps-print-background-image'.
711 ;; For example, if we wish to print text "preliminary" on all pages and text
712 ;; "special" on page 5 and from page 11 to page 17, we could specify:
714 ;; (setq ps-print-background-text
717 ;; "LeftMargin" "BottomMargin PrintHeight add" ; X and Y position
718 ;; ; (upper left corner)
720 ;; "PrintHeight neg PrintPageWidth atan" ; angle
721 ;; 5 (11 . 17)) ; page list
724 ;; Similarly, we could print image "~/images/EPS-image1.ps" on all pages and
725 ;; image "~/images/EPS-image2.ps" on page 5 and from page 11 to page 17, we
728 ;; (setq ps-print-background-image
729 ;; '(("~/images/EPS-image1.ps"
730 ;; "LeftMargin" "BottomMargin") ; X and Y position (lower left corner)
731 ;; ("~/images/EPS-image2.ps"
732 ;; "LeftMargin" "BottomMargin PrintHeight 2 div add" ; X and Y position
733 ;; ; (upper left corner)
735 ;; 5 (11 . 17)) ; page list
738 ;; If it is not possible to read (or does not exist) an image file, that file
741 ;; The printing order is:
743 ;; 1. Print zebra stripes
744 ;; 2. Print background texts that it should be on all pages
745 ;; 3. Print background images that it should be on all pages
746 ;; 4. Print background texts only for current page (if any)
747 ;; 5. Print background images only for current page (if any)
749 ;; 7. Print buffer text (with faces, if specified) and line number
755 ;; Some tools are provided to help you customize your font setup.
757 ;; `ps-setup' returns (some part of) the current setup.
759 ;; To avoid wrapping too many lines, you may want to adjust the
760 ;; left and right margins and the font size. On UN*X systems, do:
761 ;; pr -t file | awk '{printf "%3d %s\n", length($0), $0}' | sort -r | head
762 ;; to determine the longest lines of your file.
763 ;; Then, the command `ps-line-lengths' will give you the correspondence
764 ;; between a line length (number of characters) and the maximum font
765 ;; size which doesn't wrap such a line with the current ps-print setup.
767 ;; The commands `ps-nb-pages-buffer' and `ps-nb-pages-region' display
768 ;; the correspondence between a number of pages and the maximum font
769 ;; size which allow the number of lines of the current buffer or of
770 ;; its current region to fit in this number of pages.
772 ;; NOTE: line folding is not taken into account in this process and could
773 ;; change the results.
