If you’re on a Windows computer, this is how you can find the IP address of a network printer.
1. In Windows 7, From Start menu type "Devices and Printers."
2. Right-click on the appropriate printer in the list and select “Printer Properties.” In the location box under the General tab, you should see the IP address of the printer.
If the location box happens to be empty, click on the “Ports” tab in Printer Properties, highlight/select the port that is checked off (there should just be one) and click the “Configure Port…” button. In the next window, you should see the IP address in the “Printer Name or IP Address” text box
