Logon to the print server with Administrative priviledges.

Close the Printers Folder.

In Control Panel / Services, browse to the Spooler service and stop it.. If you are using TCP/IP Printing Services, stop it also.

Delete the .spl and .shd files from %SystemRoot%\System32\Spool\Printers that have the approximate time and date of the print job causing the problem.

Restart the sevices that you stopped.

NOTE: In some cases, Windows NT may not allow the *.spl file(s) to be deleted or renamed. Renaming the *.shd file and restarting the spooler service may be enough to clear the problem.
