Please somebody report this bug at http://bugs.ghostscript.com (I've entered there at http://bugs.ghostscript.com/createaccount.cgi my email but received no confirmation email). So I can't access bugs.ghostscript.com service.

$ pcal 03 2014 > ~/t/cal.ps
$ ps2pdf ~/t/cal.ps ~/t/cal.pdf
$ acroread ~/t/cal.pdf

Then I printed it in Acrobat Reader with its "Output Mode" setting being "Color" and "High Quality Grayscale". They outputted no gray regions at all or gray regions as VERY fade color which a man would have trouble to read.

But! When I've set Acrobat Reader to "Black Only Grayscale" it printed a high quality page with all needed degrees of gray.

It seems that we have a trouble with GhostScript confusing different "quality" settings.

$ pcal 03 2014 | gv -grayscale -

This outputs a colored window (PNG attached), despite of -grayscale argument.

It seems that -grayscale meaning is reverted. (Without -grayscale flag it looks like grayscale).
