Issue: Similarly named printers on MacOS
SPM can’t differentiate between multiple printers if the first characters of the name are the same.
Solution: Rename the printers.
On your Mac, choose Apple menu > System Preferences, then click Printers & Scanners.
Select the printer in the list on the left.
Click Options & Supplies, then click General.
Type the new name and click OK.
You can also rename a printer by Control-click a printer in the Printers list in Printers & Scanners preferences, choose “Rename printer” from the shortcut menu, enter a name and location, then click OK.
