;; You can also set `ps-print-color-p' to 'black-white to have a better looking

+;; ps-print also detects if the text foreground and background colors are
+;; equals when `ps-fg-validate-p' is non-nil. In this case, if these colors
+;; are used, no text will appear. You can use `ps-fg-list' to give a list of
+;; foreground colors to be used when text foreground and background colors are
+;; equals. It'll be used the first foreground color in `ps-fg-list' which is
+;; different from the background color. If `ps-fg-list' is nil, the default
+;; foreground color is used.
