You can reset the printing system as a final step when other steps for resolving printer issues don't succeed. Resetting the printing system causes all printers and scanners—including their custom settings—to be removed from the Printers & Scanners pane of System Preferences. All queues and jobs are also removed. Afterward, you'll need to set up your printers and scanners again.
- Choose System Preferences from the Apple menu.
- Click Printers & Scanners.
In some versions of OS X, this preference is named Print & Scan or Print & Fax.
- Control-click anywhere in the list of devices on the left, then choose “Reset printing system” from the shortcut menu that appears.
