Hello,
We have an interesting problem here where I work and all my search's have come up empty handed. Hoping someone else either has had this problem or can brainstorm a few ideas.
Operating System: Windows Server 2008 R2
Role: Print and Document Services
Printers affected: Any HP Universal Print Driver version
Problem: October-November Random HP printers that had an HP universal print driver installed would start printing out 'garbage' aka non-sense. This usually indicates a bad driver, but no driver changes had been made to the print server and nothing in the event log revealed bad driver, nor with the print queues in question.
It happens randomly and only on this printer server (we have 5 other print servers that are unaffected with varying OS's) and has happened to about 50 of our HP printers with at least 1-2 a day.
It doesn't matter what version of HP UPD was installed (we had 3 different versions, v5.2 v5.9 and the most recent).
Simply restarting the print spooler and/or restarting the print server has not assisted.
I am able to get the queues working in 1 of 2 ways which make me suspect a caching issue:
1) Delete and recreate the queue completely from scratch
2) Change the Driver to a NON Hp print driver, restart the spooler, change the driver back to an HP driver and restart the spooler again.
Any idea's what could be causing this?
Does any one know where the drivers are cached, not stored, but cached perhaps I can clear it out?
