How to connect a network printer to a device running MacOS. Devices connected via USB do not need to be added using this method.
Instructions
Open System Preferences and then open the Printers & Scanners button
Click the + button in the bottom left-hand side of the Printers field.
Select the IP option and enter the IP address of your printer. Some options will automatically fill.
Choose the Line Printer Daemon Protocol.
Enter your preferred name in the Name field.
Optional: Enter a room number in the Location field.
Click Add to add the printer.
If MacOS is unable to determine the exact configuration of your printer, it will ask you a few questions about what hardware configurations the printer has (tray options/duplex printing/etc.). Select the appropriate options. If you are unsure, you can leave the options unchecked.
