So your working away on your PC and you send a print but it fails, your out of ink, out of paper or just plain unlucky. You restock your printer but the failed print wont clear in the Queue, the solution is simple:
1.Click "start" and go to "Run"
2.Type "services.msc" at the prompt which will open the Services
3.Scroll down the alphabetical list in the right window pane until you come
to the entry with the name "Print Spooler"
4.Right-click this entry, then select "stop". This will stop the computer
running the process that holds your print queues.
5.Leaving that window open for now, click again on "Start", and then click
"My Computer" to open a Windows Explorer window.
The usual path to the spool folder is
C:\WINDOWS\system32\spool\PRINTERS, but yours may be slightly
different. Your windows drive may have another name for instance, but this would
be uncommon. So click on your Windows drive (usually C), then double-click on
the Windows folder, and then find the System32 folder and double-click on
that. Windows may warn you that you are about to view system files, but click
"View files anyway" message and search out the "spool folder". Within the
Spool folder is your Printers folder, and you should open
7.Delete every file within this folder to empty the jammed print queue
(pressing the "ctrl" and "a" keys will select all files and then you can just
8.Close the explorer window now that we have emptied the cleared spool files,
and return to your Services window. we must re-start the Print spool
service, and do so by right-clicking the Print Spool entry and selecting
"Start" from the list. Close the services window and try printing again
