Follow-up Comment #3, bug #41737 (project gv):

$ 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.
