Hi,
From the Desktop, hold down the Windows key and press R. Into the Run window, type services.msc and hit enter. Browse down to the print spooler service, right click it and select Properties then click on the Stop button. Now browse to C:\Windows\System32\Spool\PRINTERS and delete the job inside this folder - You may need to click a prompt to gain the appropriate authority to open the PRINTERS folder.
Restart the computer and you should find the document(s) have been removed.
Regards,
DP-K
