Ethernet Setup - macOS
To be able to use your printer on a wired network with a Mac®, the Ethernet port on the printer must be activated. Next, connect one end of an Ethernet cable to the back of the printer. Then, connect the other end of the cable to your router. Finally, you'll need to download the setup file for your computer.
