If you no longer use a printer, you can delete it from your list of available printers. To do so:
- Choose Apple menu > System Preferences, then click Printers & Scanners.
- Select the printer in the list, then click Delete (-).
Note: If you delete the printer that’s set as your default printer, OS X selects another printer as your default. To use a different printer as your default, choose it from the pop-up menu in Printers & Scanners preferences.
