Many thanks to the responders to my problem with or new 1055CM plotter.
Suggestions for a fix included:

Print > Properties > Advanced > Process Document 'In Computer' ?  This
sometimes makes a difference...         The PS3_RTL driver doesn't have this
option. I was informed that HP has just recently posted a new driver
(October 2001). I'll evaluate this one.

Use ArcPress - I don't have ArcPress at the moment, but this is perhaps an
option. My question is: We already use Adobe Acrobat to produce printable
files. Will ArcPress provide enhancements beyond what I can get from
Acrobat? I have to justify another $300.

Others suggested that the problems seemed to arise from running out of
memory in the printer. Since Arcview tends to produce very large print
files, perhaps this is the problem. One suggested turning the printer &
computer off then powering up.  I did & still no joy.

I'm experience a strange, ArcView specific problem with our 6 month old
HP 1055CM plotter.
Symptoms:
        I print to the plotter using the HP DesignJet 1055Cm PS3_RTL driver.

Initially, this driver worked great with no problems.  Recently, however,
the print jobs will often result in an error message on the printer (not on
the
computer) and then a message stating there was a problem processing the
data, flushing
print job. Press <Enter>.  The printer then starts to spew out paper,
bringing about
frantic attempts to stop/cancel the job.  The sequence I've found successful
is to press the
<Cancel> then the <Enter> key to cancel the job. Arcview is the only
software causing this problem. I can produce an Adobe Acrobat file of the
layout & print with no problem.  I was having this problem consistently, but
recently it went away. A coworker has begun having this problem with
particular projects.  I am investigating whether a particular theme or layer
might be causing this problem. Has anyone had similar problems with this
printer, and have you been able to solve it?
