+;; 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 (\005) 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).
+;; 'control-8-bit printable form for control and *control* 8-bit characters
+;; (characters from \000 to \037 and \177 to \237).
+;; 'control printable form for control character
+;; (characters from \000 to \037 and \177).
+;; nil raw character (no printable form).
+;;
+;; 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.
+;;
+;;
;; Line Number

;; 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-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.
;; 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.

;; Automatic font-attribute detection doesn't work well, especially
