i wanted to clear more than 12000 Printer jobs in a Restaurants POS printer.
this happened because the users have turned off the Printer and print all the Transactions..
because of huge queue it does't show the Pending Jobs when open the Printer..
when they Turned on the printer it started to print all the pending printer jobs
so i wanted to find a way to delete all the jobs without Removing the printer..
Here we go i found a solution and wanted to share with you
.... in any case this happened to you just follow these simple steps. 
1. XP – click ‘Start’ then click ‘Run’ and in the Run window type CMD then press ‘OK’ – this opens a Command Prompt window. Now skip to Step 3
2. Vista/7 – click ‘Start’ and type Command in the search box. Right click on the ‘Command Prompt’ result in the search results above it and select ‘Run As Administrator’ – this opens a Command Prompt window
3. All version of Windows – in the Command Prompt window:
4. Type net stop spooler then press the Enter key
5. Type del %windir%\system32\spool\printers\*.* /q then press the Enter key (Note: the only spaces in this command are a single space between del and %, and a single space between * and /q)
6. Type net start spooler then press the Enter key
7. Type exit then press the Enter key to exit the Command Prompt window
