How to Find a Printer's IP Address in a Mac
The Internet Protocol address of an electronic device identifies where the device is on a network, according to the Queensland Media Group. Mac computers use the CUPS Unix Printing System to manage printing tasks. This system is integrated with the printer menu in OS X and provides access to information like the printer’s IP Address. Only a networked printer or a printer server will have an IP address.
Go to the “Apple” menu and select the “System Preferences” option. Click “Print & Fax” from the menu.
Select the printer from the menu on the left and press the “Open Print Queue” button.
Open the “Printer” menu at the top of the screen and select “Print Test Page.”
Go to the “Device URI” on the CUPS text page and look towards the end of the string. The IP address appears after “ip=.”
