Cancel the print job from the computer.
Windows
Double-click the printer icon on the task bar of your computer.
Select the print job you want to cancel, click the [Document] menu, and then click [Cancel].
Mac OS X
Start Print Center.
Select the name of the job you want to cancel.
Click the Pause icon, and then click the Trash icon.
If the printer is shared by multiple computers, be careful not to cancel the print job of another user.
If you cancel a print job that has already been processed, printing may continue for a few pages before being canceled.
If you cancel a Locked Print job, the machine might have already stored some pages of the job as a Locked Print file. If this happens, use the control panel to delete the Locked Print file.
It may take a while to cancel a large print job.
For details about deleting a Locked Print file, see Deleting a Locked Print file.
