Do you have any 32 bit Windows 7 machines and do they show the symptoms?
I’m wondering if it is because to are using Win 2003 GPO against Win 7.
Has this problem shown up in any non Win 7 machines
First off, this is not really an answer above….WIN 2003 is built to support all GPO’s for WIN 7. I have this exact same problem across the board. Multiple models of printers. I use the PCL drivers for my networked printers and host 3 different brands/models. All printers have the same issue. Sometimes this issue will go away for weeks at a time. Then it comes back for 7 or 8 days straight….then it goes away. I still have not found a concrete answer as to why this happens. I have uninstalled / reinstalled printers multiple times and this just seem to be a very random, common problem when upgrading to Win 7. Only machines that i HAVE NOT seen this on are clean factory Win 7 machines that we order from Dell. But when i UPGRADE, i am faced with this problem.
