You may face this situation many occasions .The print order is sent, suddenly the LAN connection dies. The job cannot be cancelled as usual through the print control. Now it is blocking all further printing attempts as well.
Using the usual dialog, you can actually delete those orders, which are still in progress. In order to get rid of the stuck print order and enable printing the queued orders, you must first manually stop the Printer Spooler service and then delete the file. For better control, start the commands in the command prompt.For that, open the command ‘Run’ in the ‘Start’ menu, then enter ‘cmd’ and then press ‘Enter’. In Vista, enter ‘cmd’ in the search box in the start menu, right click on this entry and select context command ‘Run as administrator’. Now use the following command
net stop spooler
and check, whether the print queue is gone. Then open Windows Explorer and navigate to the ‘C:\Windows\system32\spool\PRINTERS’ folder. There, delete all SPL files – they contain the affected print data. Now switch back to the still open command prompt. Enter the following here:
net start spooler
And the printing queue will start working smoothly again. After this, the command must be deleted, so that you can also use the printer again.
