I have scripted DeleteAllPrintJobs.bat to delete all the print jobs in the queue.

Pending print jobs are located in the %systemroot%\system32\spool\printers folder, unless you moved it.

If you want to delete all the print jobs in the queue, run DeleteAllPrintJobs.bat, using any of the following:

Start / Run / DeleteAllPrintJobs / OK
Open a CMD.EXE window and type DeleteAllPrintJobs
Double-click a shortcut to DeleteAllPrintJobs.bat

DeleteAllPrintJobs.bat contains:

                              @echo off                              net stop spooler                              ping 127.0.0.1 -n 4 >nul                              del %systemroot%\system32\spool\printers\*.* /F /Q /S                              ping 127.0.0.1 -n 3 >nul                              net start spooler
