..However, as the HP lazer jet printer they have there seems to work with no issues at all...

Don't you just hate it when the competitions equipment doesn't have the problem? Well then, of course, the problem is with your copier!

I can't say as I know a "fix" for this but a few things to check are enable/disable SNMP in the printer port config., enable/disable SNMP at the copier, check firewall settings, or power management settings.

I've seen it a couple times now that the windows firewall blocks printing after a windows update. Since it happens almost immediately, I doubt the power management settings will make any difference but make sure it is set to never turn off the HDD's.

It sounds more like a SNMP issue. Try disabling it in the printer port config. and at the copier. Check that the copier and Win 7 SNMP community names match. As a last ditch effort I'd update the firmware on the copier, mostly just to say you've done everything you can at the copier end. Then ask them to do the latest windows update. GL

There was a firmware update (special not base) to resolve dropping off of the network. That may explain what is happening. Also which driver are they using? I only see the universal driver available and that is not my best friend.
