Can't delete a job in the printer queue

Hi,
if you have a problem with printing a document and you can't abort this print in the queue, you can do the following steps:
At first you should restart the spool service:
net stop spooler 
net start spooler

If it's not possible to remove the document from the queue after these step, you can remove the files in the following directory:
%WinDir%/System32/Spool/Printers
There are two files for each document in the printer queue which you can delete if you want for removing them from the printer queue.
