I get multiple errors in the event log complaining about printers that are not installed on the computer.
"Driver Canon MP210 series Printer required for printer Canon MP210 series Printer is unknown. Contact the administrator to install the driver before you log in again."
Errors for several other printers as well. No printers are installed under "Printers and Faxes", and no applications are being run on this computer (it is essentially shared folder server for backups).
What could be requesting printers that don't exist?
