How to Find the Printer's IP Address in Windows?

Go to 'Control panel' > Hardware & Sound > Devices and Printers.

In that window, you'll find all the printers available on your network. Now, simply right-click on any printer you want and select 'Printer properties' from the popped up menu.

Now go to 'General' tab in the properties window and in the Location box, you'll find your Printer's IP address.

P.S: In some cases, the Location box would be empty. Then, you can click on the 'Ports' tab in the properties window > highlight/select the port that is not checked > click the 'Configure port' button and on the next screen, you'll see the IP address of your printer in the text box titled 'Printer Name or IP Address'.
