If I'm understanding correctly what you've written, it seems to me
that your problem may not be ghostview. I think you might want to
try specifying different drivers for your printer to see if others
might work better.
You might also want to provide a bit of information about your system.
I run Debian testing on all of my systems, and I recently had to
switch from hpijs drivers to CUPS+Gutenprint on all of my HP
LaserJet printers for a similar problem. (They weren't dithering or
shading properly, but simly printing black& white.)
Note that while Gutenprint has excellent support for Epson, Canon
and other colour inkjects, PCL-based HP deskjets are (AFAICT) only
supported in black and white. Good for monochrome lasers where
the fine dithering can greatly improve quality, but not so good for
inkjets, so if this is the case, you might wasnt to look at hplip
instead.
There currently isn't a maintainer for the PCL driver to add
colour support. If someone took the time, it would probably add
significant quality improvement over hplip/hpijs, since it would
make use of the more advanced dithering and colour handling of
gutenprint.

Thank you very, very much for this information. It fits with what I've
seen. And I'm just in the process of adding a couple of inkjet-based HP
MFPs to the mix here, so this is very very timely bit of data for me.
Regards,
Gilbert
