I manage a network of about 20 workstations, 5 printers, and some other fun stuff.
Most of the workstations are windows based, and if I need to find out the IP address of one of my printers on the network I can easily go to print properties and see the port configuration… its not that easy on the MAC… atleast until I figured out the below. You see, Mac uses a unix based printing language called CUPS, and there is actually a neat little web interface for this if you enable it… with that you can see more (like the printer’s IP address).
So two steps, 1.enable cups web interface, and then 2. find the IP address of the printer you want.
1a. System Preferences -> Sharing -> Check off “Printer Sharing”
1b. Open Terminal, type the following: cupsctl WebInterface=yes
2a. Open the CUPS web interface with the following address in your safari browser http://127.0.0.1:631
2b. Click the tab Printers -> Then the click the name of the printer
It should display some basic info about this printer, one of the lines will have it’s local IP address
