Cancel a print job (Mac OS X)
If the print job is currently printing, cancel it by pressing the Cancel button on the product control
If the print job is too far into the printing process, you might not have the option to cancel it.
Pressing the Cancel button clears the job that the product is currently processing. If more
than one print job is waiting, pressing the Cancel button clears the print job that currently displays on
the product control panel.
You can also cancel a print job from a software program or a print queue.
Typically, a dialog box displays briefly on the computer screen, allowing you
to cancel the print job.
Mac print queue:
Open the print queue by double-clicking the product icon in the dock. Highlight
the print job, and then click Delete.
