I love my 932C. Works great. Cartridges are a little expensive, like all
HP inkjets, but it prints well.

Well, ifhp is smart enough to use ghostscript in order to get from
PostScript to PCL when it has to, but I don't think it can do what you want
directly. It has to be aware that it should be producing the color
superset of PCL 3 that the 932C speaks, and I'm not sure it can. I beat on
it for a while, then gave up and wrote a shell script to support the 932C.
I reproduce it below.

Yes, it's a hack. I'm certainly no great shakes at shell scripting... in
my defense, all I can say is that it works. This is more or less set up to
print pictures... letter size for my 932C and tabloid size for my 1120C. I
don't print text with them... that's what real PostScript laser printers
are for.

Forget it. The ghostscript documentation doesn't match the way hpijs works
now. Let me qualify that by saying that I'm specifically talking about gs
7.07 and hpijs 1.5 from unstable. The hpijs web site is your friend.
