If you cancel a print job that has already been processed, printing may continue for a few pages before being canceled.
You can also open the print job queue window by double-clicking the printer icon in the [Printers] window.
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.
