For these jobs, files are ranging anywhere from 3 to 20 pages. One of
them used a Japanese font. The one that I was able to print later in
the day from the original document was an excerpt from a journal, mostly
text with a few simple B&W figures. I haven't examined the others yet.
I'll post an update here in a bit.

In our case, setting up the printer via samba on Mac clients seems to
work the best. It's the easiest for the user to do, anyway. Otherwise,
they have to do a bit of manual setup on the local (to their machine)
cups server. And if it takes more than two steps, it's too much for
them to deal with.

Reproducing problems easily is good.

I'll keep playing with this, see if I can find anything out there.
Thanks again.
