I have a strange issue coming up at our school. We have about 60 HP Deskjet 6940 printers on Windows XP Pro. In the last week 9 teacher computers stopped being able to print to this model printer. When I delete the printer and plug it back in it does recognize the printer and installs the drivers for it fine. These computers can still print to networked printers fine. We have not made any changes to these systems which would cause this.
The error messages I get when trying to print:
-Notepad: "The handle is invalid"
-Test page: "Test page failed to print. Would like like to view the printer troubleshooter for assistance? Operation could not be completed."
-Word: "Windows cannot print due to a problem with the current printer setup"
I have done the following to try and diagnose the problem:
-Run antivirus check on the computer as well as on the drive itself from another computer
-Swapped with a known good printer of the same model(does not work)
-Swapped all cables with known good ones
-Run system file check
-Restarted spooler service
-Called HP level 2 support (they could not figure out the problem either, just had me repeat what I've already tried)
If anyone could shed light on this I would immensely appreciate it as I have lost sleep over it for the past week. Thanks!
