Thank you for your detailed information. I had not heard of the
Stressprinter utility but it sounds very helpful.
I may have found part of the problem. I noticed in the spooler directory
there was a number of tmp files from 2007. I deleted them as soon as I
did the Citrix Print Manager Service started acting normal again
(starting and stopping from the MMC). I checked each server in the farm
and they all had old print files from 2007. I'm going to wait a few days
and see if the problem reoccurs and in the mean time test all our print
drivers with the Stressprinter utility. So far all the print drivers
tested have 0 errors but I will carefully go through each driver on the
server to ensure I don't miss any.
Again, thanks very much for your help.

Hi Matthew,
It's highly likely that you've got a problem introduced by one or more
print drivers.
THe main culrpit seems to be HP, and while they're starting to work hard
on fixing all new drivers, any driver older than about 12 months has to
be tested before you let it loose in your production environment. It
appears that in addition to code that can't handle multi-threaded
operation, the HP developers managed to produce some really badly
written drivers that cause memory corruption etc as well.
Use the addprinter or Stressprinter utilities (download from Citrix) to
test all your production drivers. DON'T do the testing on a production
server, backup the existing production printer environment with the
Microsoft print migrator tools (PrintMig 3) and restore it on to a test
machine (can be an XP workstation).
There are 2 populations of bad drivers, ones that crash the spooler
which obviously have to be replaced and ones that have a huge CPU
overhead in establishing printer queues, which should be replaced. The
next version of StressPrinter will hopefully give us a handle to the
high CPU drivers but until that happens addprinter may be more useful.
If and when Citrix finally get their UPD print gateway finished you will
be able to run your Citrix (XENApp? ;-) servers without installed
printer drivers. Until that happens you need to rigorously test every
printer driver used in your environment. Or use a third party UPD
product to do your printing (ThinPrint, Tricerat, Provsion Networks
etc).
regards,
Rick

Does the "Citrix Print Manager Service" failing to stop conclusively
indicate this is a printer related issue or is this just a symptom of
the problem? Any suggestions would be most welcome.
