;; 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 (Lucid or FSF) and a fontifying package such as font-lock
-;; or hilit.
+;; Emacs 19 or Lucid Emacs, together with a fontifying package such as
+;; font-lock or hilit.

;; Installing ps-print
;; -------------------
;;
-;; 1. Place ps-print.el somewhere in your load-path and byte-compile
-;; it. You can ignore all byte-compiler warnings; they are the
-;; result of multi-Emacs support. This step is necessary only if
-;; you're installing your own ps-print; if ps-print came with your
-;; copy of Emacs, this been done already.
-;;
-;; 2. Place in your .emacs file the line
-;;
-;; (require 'ps-print)
-;;
-;; to load ps-print. Or you may cause any of the ps-print commands
-;; to be autoloaded with an autoload command such as:
-;;
-;; (autoload 'ps-print-buffer "ps-print"
-;; "Generate and print a PostScript image of the buffer..." t)
-;;
-;; 3. Make sure that the variables ps-lpr-command and ps-lpr-switches
-;; contain appropriate values for your system; see the usage notes
-;; below and the documentation of these variables.
+;; Make sure that the variables ps-lpr-command and ps-lpr-switches
+;; contain appropriate values for your system; see the usage notes
+;; below and the documentation of these variables.
;;
;; Using ps-print
;; --------------
;; 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
+;; then ps-print won't work properly. ps-lpr-command must name
;; a program that does not format the files it prints.
;;
;;
;; formats for; it should contain one of the symbols ps-letter,
;; ps-legal, or ps-a4. The default is ps-letter.
;;
-;;
-;; New in version 1.6
-;; ------------------
-;; Color output capability.
-;;
-;; Automatic detection of font attributes (bold, italic).
-;;
-;; Configurable headers with page numbers.
-;;
-;; Slightly faster.
-;;
-;; Support for different paper sizes.
-;;
-;; Better conformance to PostScript Document Structure Conventions.
-;;
;;
;; Known bugs and limitations of ps-print:
;; --------------------------------------
+;; Automatic font-attribute detection doesn't work will, especially
+;; with hilit19 and older versions of get-create-face. Users having
+;; problems with auto-font detection should use the lists ps-italic-
+;; faces and ps-bold-faces and/or turn off automatic detection by
+;; setting ps-auto-font-detect to nil.
+;;
;; Color output doesn't yet work in XEmacs.
;;
-;; Slow. Because XEmacs implements certain functions, such as
-;; next-property-change, in lisp, printing with faces is several times
-;; slower in XEmacs. In Emacs, these functions are implemented in C,
-;; so Emacs is somewhat faster.
+;; Still too slow; could use some hand-optimization.
;;
;; ASCII Control characters other than tab, linefeed and pagefeed are
;; not handled.
