Have you tried to print a document and not been able to? Perhaps there is a job in the print que holding things up.
Turn off the Print Spooler in Services under Administrative Tools.
Use Windows Explorer to go to System32\Spool\Printers to delete the offending jobs. Stopping the Print Spooler service Turn on the Fax Service, so turn it back on after Starting the Print Spooler again.
If this fails remove and reinstall the printer driver.
