If what V-2 said doesn't solve youre problem and the spooler service keeps shutting down do the following :
Delete the contents of the following folders :
C:\Windows\System32\spool\PRINTERS
and
C:\Windows\System32\spool\drivers
After you have done this disconnect youre printers and after a short while reconnect them again.
If this step goes wrong, delete and reconfigure the printer once more.
Hope this helps
