Deleting Jammed Print Jobs
Occasionally when you print a document from your computer it will get stuck in the print queue for one reason or another. Then if you print again it, your print job will back up after the first print job. You may have a printer icon with a red question mark in the taskbar by the clock. When you double click it, you will see your jammed print jobs. From there you can go to the Printer menu and select Cancel All Documents to clear them all out or you can highlight your print job and click on the Document menu and click on Cancel.
Many times the first print job that got stuck will not cancel no matter how many times you try to manually cancel it. Even if you reboot the computer, there is a good chance the job will still be in the print queue when it starts back up. The way to solve this problem is to stop the Print Spooler service. The Print Spooler service is software that takes print jobs and temporarily stores them in a buffer and then sends each to the printer when the printer is able to process it.
To stop the Print Spooler service, click on Start then Run and type in services.msc to open the local services running on the computer. From here, find the Print Spooler service, right click it and click on Stop. After that, reboot the computer which will restart the Print Spooler and hopefully clear out any leftover print jobs. You may have to do this a couple of times before it clears out.
