Print Jobs do not Print, but the Windows Test Page does.
There are print jobs stuck in the print spooler. The Windows test page from the General tab on the driver can print because it bypasses the spooler. To free up the spooler and let print jobs through or allow for the print driver to be deleted, clear out the files in the spooler.
To delete the spool files in Microsoft Windows XP
Stop the spooler
Click Start, Control Panel, Performance and Maintenance, Administrative Tools, then Services.
Scroll down the list of services for Print Spooler.
Right click Print Spooler and Stop.
Delete the spool files.
Click My Computer.
Go to C:\WINDOWS\system32\spool\PRINTERS\ .
Delete all of the files inside this folder.
NOTE: If the spooler is working correctly, this folder should be empty when the computer is not printing. It normally deletes these files out of this folder after they have been sent to the printer. Deleting files that are stuck can free up the spooler and allow it to continue normal operation.
