Cancel a printing job by using the physical controls on the printer or by removing the job from the printing queue. If Windows is slow to respond, turn the printer off, and then remove the job to save paper.
Most printers have Cancel or Stop buttons that are easy to identify. Pressing the button cancels the current printing job.
Alternatively, it is possible to remove a printing job from Windows. Click the Start button, and type "Devices and Printers" into the search box. Right click the printer that is currently printing, and select See What's Printing. Right click any item on the printing queue, and click Cancel to cancel the printing job.
The search box is next to the Start button in Windows 10. If using Windows 8 or 8.1, open the Start Screen and start typing to use the search function.
