Find IP address of ethernet printer when Location is “Home” I want to find the IP address of my home ethernet printer. When I follow instructions like here:
https://www.youtube.com/watch?v=rGK3DUbFz2c
in both cases, it says that the Location is Home. How do I do this?
A sure fire way to find the IP address of your printer (any device for that matter) is to ping the broadcast address.


Get your broadcast address:

ifconfig en0 | grep broadcast | awk '{ print $6 }'


Use en0 for wired ethernet and en1 if you are on wireless.  You will get output similar to the following:

 192.168.1.255

Ping the broadcast address

ping 192.168.1.255


Let it run for about 30 seconds or so....Then hit CtrlC  to stop it.

Alternatively, you can specify the time by adding it to the ping command:

ping -t 30 192.168.1.255

Type arp -a and look for your printer.  You will get output similar to what's shown below (IPs have been changed for security).

In my case, I have two  printers on my network - my HP CP2025dn and a Lexmark E260 with DNS/IPs as cp2025dn.home/192.168.1.25 and lex.home/192.168.1.55 respectively.

As for the "Location" field, this is something that is set up by the user or Sys Admin.  In my case, it's getting the information directly from the printer.  See printer Setting page below for my Lexmark printer.  What you saw in the YouTube video is misleading because the IP address had to be manually populated in this field.
