Have you ever had one of those print jobs that you cannot cancel. You try cancelling it, switching off the printer, restarting the computer, and it still wants to print?
The following commands should solve the problem once and for all. They stop the print spooler, delete any print jobs, then restart the print spooler service.
net stop spooler del %systemroot%\system32\spool\printers\*.shd del %systemroot%\system32\spool\printers\*.spl net start spooler
You can download the commands in a handy batch file that you can simply double-click on to cancel all current print jobs at any time.
