How to Find a Printer's MAC Address

By Ruri Ranbe

The ARP table lists the IP and MAC addresses of devices connected to your computer.

Most routers and security appliances allow administrators to restrict access to a local area network via Media Access Control address filtering, or MAC authentication. This feature prevents unauthorized equipment from logging on to the network; if the MAC address of the device isn't allowed through the filter, the appliance blocks the device from the LAN. If you've connected the printer to your network but need to know its MAC address to perform administrative changes, you can find the address via the address resolution protocol. If you need to configure a security filter to allow the printer access, however, finding the MAC address might be a little more difficult.

Network-Connected Printer

Press "Windows-X" and choose "Command Prompt (Admin)" from the menu that appears. Command Prompt opens.

Input the following into the console:

ping #.#.#.#

Replace each hash, or "#" symbol, with the appropriate octet. For example, if the IP address of the printer is, replace the first hash with the octet "192," the second hash with octet "168" and so on. Press "Enter."

Input the following into CMD and then press "Enter":

arp -a

Locate the IP address of the printer in the table. Review the information under the Physical Address field to find the printer's MAC address.

New Printer

Inspect the back and bottom of the unit for a product sticker. Check the label for a 12-digit address.

Navigate through the settings on the printer's control panel to find an option to print a configuration page. You can sometimes find the option in "Report Settings," "Network Setup," "Print Setup," "Self Test" or a similar menu.

Review the manual that came with the printer for instructions to locate the MAC address if you're unable to find the address following these steps.
