Unlike a network IP address, a Media Access Control -- or MAC -- address is assigned to your printer's network adapter by the device's manufacturer. This unique identifier can help you to secure the printer on your network by using your router's MAC address filtering feature. Once enabled, only a device with a MAC address on the filter list can access your network. To find your printer's MAC address, run the "arp" command using the Command Prompt utility. However, you will need your printer's IP address -- which is accessible through the Printer Properties utility -- before you run the command.
