+
+	* ps-print.el: Problem with foreground and background color when
+	printing a buffer with and without faces.  Reported by Christian
+	Schlauer <cs-muelleimer-rubbish.bin@arcor.de>.
+	(ps-print-version): New version 6.7.5.
+	(ps-default-fg): Change default value to nil, so black color is used
+	when a face does not specify a foreground color.
+	(ps-default-bg): Change default value to nil, so white color is used
+	for background color.
+	(ps-begin-job): Fix code.
