If your printer stops due to some error (e.g. paper or ink), OS X will usually stop all jobs for the printer. The result is a lack of printer operation even after you resolve the problem. You try printing something but nothing comes out.
- Turn off your printer, unplug its power cord, wait a few seconds, then replug and turn it back on. Many printers just won't reset unless you yank the cord. Don't trust that it really goes off when you push the button.
- Go to System Preferences : Print and Fax (Print and Scan, depending on your OS).
- Highlight the printer's name and click Open Print Queue.
