We recently converted an office to iPrint printing. In this conversion we
did the following:

1) Removed all previous printers
2) Removed all standard TCP/IP ports
3) Removed all installed printer drivers
4) Installed the iPrint client
5) Installed the necessary iPrint printers

Steps 1-3 should give us a pretty clean environment, which should help avoid
problems with outdated driver files, corrupt drivers, etc. Steps 4 and 5
install only the printers and drivers that we want to have on the machines.

Everything seems to be working well, with one exception. There is an HP
LaserJet 4200tn that chokes whenever someone tries to print a PDF file. The
HP 4200 iPrint printer has a printer profile associated with it, uses XP
drivers (all workstations are on XP), and the configuration of the printer


where "aa.bbb.cc.ddd" represents the IP address of the printer, which has
been verified as correct.

When printing from Word, Excel, Outlook, or doing a test page from the
printer properties, it works fine. But PDF files cause problems. Often
times, just switching the selected printer to the HP 4200 inside Adobe
Reader causes Adobe Reader to stop responding.

At first, I thought that the problem was with the iPrint printer itself, or
the driver that it uses. However, I created two new iPrint printers--one
using the PCL 5e driver for XP and the other using the PS driver for XP--and
both of those printers exhibit the same behavior when trying to print a PDF
file. So as a test I setup the printer on a workstation using the standard
TCP/IP port (not going through iPrint) and that works just fine when
printing PDF files.

This made me think that the problem might be with Windows or Adobe. So I
checked the event logs on one of the PCs and found the following error in
the application log:

I've researched this error and found that it appears to be a generic kind of
error with no one obvious cause. I've tried all the recommended fixes for
this error that I could find, including removing Windows hot fix 908531,
deleting VERCLSID.EXE, creating a new value in the registry, and insuring
that the latest version of the Novell client is installed. None of these
measures has resolved the problem. Furthermore, this particular error does
NOT occur on all the machines that are having problems printing PDF files on
the HP 4200 printer. Most machines are currently running Adobe Reader
7.0.5. I updated one machine to Adobe Reader 7.0.7 but that did not make a

I have noticed that during these lock-ups caused by PDF files, the CPU
utilization is 100% and that most of that is accounted for by the spooler
service, but I don't know if that's the problem or just a symptom.

Has anyone else encountered problems printing PDF files through iPrint? Can
anyone recommend a way to solve my problem with this HP 4200 printer?
