+;; sending, for example, a ^D (\004) to printer, it is sent the string "^D".
;;
;; Valid values for `ps-print-control-characters' are:
;;
-;; '8-bit printable form for control and 8-bit characters
-;; (characters from \000 to \037 and \177 to \377).

+;; 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.
+;;
+;; 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)
+;;
+;;
;; Line Number
;; -----------
;;
;; 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.
+;; of the font for ordinary text, when generating PostScript.
;; Its value is a float.

;; Similarly, the variable `ps-header-font-family' determines
