It says its On Hold, I printed this paper ages ago, and I can't delete it! I tried clicking the delete button, hitting delete on my keyboard, restarting, and the application won't Auto Quit anymore because of it! How do I get rid of it?😕😕😕😕😕😕😕
You could try pausing the printer, and then deleting the task.
In some circumstances, Apple advises users to delete the printer definition and add it back again (example). Perhaps a confused print queue is a circumstance where that would be the simplest solution. Even though if seems rather drastic, it might be the fastest fix!
