Thanks for the reply.  I reported in a later email that I tried the
following (with the resolution entry you described for the model):

===========
HPLJ4050-PCL5.default-printer-resolution: 600

... in /usr/X11R6/lib/X11/xserver/C/print/attributes/document
===========

But I still got the same error message and no print.  Maybe 600 is not
supported - I could try a different value, but I'd only be guessing at
what might be supported.  I didn't see any error messages about that
specifically, however, and didn't crack the source yet.

That said, I haven't looked to see if there have been updates in CVS
since I tried this in October.

I'll try the 'resolution' option to xphelloworld and report back how
that goes and maybe try alternate res. values.

That'll be nice.  Is there an active dialog with someone at HP about
this?
