;; About ps-mule
;; -------------
;;
;; Valid values for `ps-multibyte-buffer' are:
;;
-;; nil This is the value to use when you are printing
-;; buffer with only ASCII and Latin characters.
+;; nil This is the value to use the default settings which
+;; is by default for printing buffer with only ASCII
+;; and Latin characters. The default setting can be
+;; changed by setting the variable
+;; `ps-mule-font-info-database-default' differently.
+;; The initial value of this variable is
+;; `ps-mule-font-info-database-latin' (see
+;; documentation).
;;
;; `non-latin-printer' This is the value to use when you have a japanese
;; or korean PostScript printer and want to print
;;
;; The default is nil.
