Remove a printer on Mac
If you no longer use a printer, you can delete it from your list of available printers.
On your Mac, choose Apple menu > System Preferences, then click Printers & Scanners.
Select the printer in the list, then click the Remove button .
If you delete the printer that’s set as your default printer, macOS selects another printer as your default. To set a different printer as your default, choose it from the pop-up menu in Printers & Scanners preferences.
