Printers are notorious for failing frequently. A quick restart of the printer or the computer usually fixes most intermittent problems, but sometimes it is better to reset your print settings and completely reinstall the printer. Consider this as a last step in troubleshooting; it is best to try other options first. You can read our guide for troubleshooting printing problems on macOS for other potential solutions.
Reset the printing system
Search for "Printers" in Spotlight or open the "Printers and Scanners" settings in System Preferences.
The Printers and Scanners window displays a list of all connected printers. If you right-click on one of them, you can select "Reset Print System" from the context menu.
By choosing this command, all current settings are cleared and all printers deleted from the list (not just the one you clicked with the right mouse button). To prevent you from doing so by accident, you must enter your password.
Since it removes all printers from the settings, you will need to manually add them. Make sure your printer is plugged in and click the "+" button at the bottom of the list. You can view connected printers or add a wireless printer on the network.
Some printers can not be added from this dialog box. If you have problems reinstalling a printer, consult your printer's manual or search online for an installation program for your printer model.
