I've got 5 HPLJ 1022n printers (wish I hadn't) on my network. They're managed by a W2K8-R2 print server. Test pages printed great yesterday, but today 3 out of the 5 print garbage characters on the test pages, to the right of the Windows logo. Additionally they print junk characters on a line or two on anything else they print.
I'm trying to understand why 3 out of 5 are doing this, when they're all using the same HP universal PCL5 driver. Since W2K8 is 64-bit, I can't get away with installing the 32-bit version of the HPUD. I'm stuck and don't know how to get out of this. I've restarted the print spooler service on each client, and they're all using the same printer mapping. It's bizarre, but I need an answer on how to fix this. Any takers?
