This document is for HP printers with an OS X operating system.
The printer cannot print from the Mac computer because a print job is stuck in the print queue. The stuck print job cannot be deleted or cancelled and prevents further print jobs from printing. The Delete Job button is grayed out and does nothing when clicked.
Figure : Example of a print job stuck in the print queue
A variety of reasons, such as a power outage, can cause this issue, but it always involves the printing process.
