-;; The variable `ps-landscape-mode' determines the orientation

-;; nil means `portrait' mode, non-nil means `landscape' mode.
+;; The variable `ps-landscape-mode' determines the orientation of the printing
+;; on the page: nil means `portrait' mode, non-nil means `landscape' mode.
;; There is no oblique mode yet, though this is easy to do in ps.
;;
-;; In landscape mode, the text is NOT scaled: you may print 70 lines
-;; in portrait mode and only 50 lignes in landscape mode.
-;; The margins represent margins in the printed paper:
-;; the top margin is the margin between the top of the page
+;; In landscape mode, the text is NOT scaled: you may print 70 lines in portrait

+;; the printed paper: the top margin is the margin between the top of the page
;; and the printed header, whatever the orientation is.
;;
-;; The variable `ps-number-of-columns' determines the number of columns
-;; both in landscape and portrait mode.
+;; The variable `ps-number-of-columns' determines the number of columns both in
+;; landscape and portrait mode.
;; You can use:
-;; - (the standard) one column portrait mode
-;; - (my favorite) two columns landscape mode (which spares trees)
-;; but also
+;; - (the standard) one column portrait mode.
+;; - (my favorite) two columns landscape mode (which spares trees).
+;; but also:
;; - one column landscape mode for files with very long lines.
-;; - multi-column portrait or landscape mode
+;; - multi-column portrait or landscape mode.
+;;
+;; The variable `ps-print-upside-down' determines other orientation for printing
+;; page: nil means `normal' printing, non-nil means `upside-down' printing. The
+;; default value is nil (`normal' printing).
+;;
+;; The `upside-down' orientation can be used in portrait or landscape mode.
;;
;;
;; Horizontal layout
;; The variable `ps-line-number' specifies whether to number each line;
;; non-nil means do so. The default is nil (don't number each line).
;;
+;; The variable `ps-line-number-step' specifies the interval that line number is
+;; printed. For example, if `ps-line-number-step' is set to 2, the printing
+;; will look like:
+;;
+;; 1 one line
+;; one line
+;; 3 one line
+;; one line
+;; 4 one line
+;; one line
+;; ...
+;;
+;; Valid values are:
+;;
+;; integer an integer that specifies the interval that line number is
+;; printed. If it's lesser than or equal to zero, it's used the
+;; value 1.
+;;
+;; `zebra' specifies that only the line number of the first line in a zebra
+;; stripe is to be printed.
+;;
+;; Any other value is treated as `zebra'.
+;; The default value is 1, so each line number is printed.
+;;
;;
;; Zebra Stripes
;; -------------
;; rebuilt when ps-print is invoked, set the variable
;; `ps-always-build-face-reference' to t.
;;
+;; If you need to print without worrying about face background color, set the
+;; variable `ps-use-face-background' which specifies if face background should
+;; be used. Valid values are:
+;;
+;; t always use face background color.
+;; nil never use face background color.
+;; (face...) list of faces whose background color will be used.
+;;
+;; Any other value will be treated as t.
+;; The default value is t.
