To find the IP address of an HP printer, you can print a network configuration page directly from the printer. Press the "Setup" or "Menu" button on the printer control panel, then navigate to the "Network" or "Wireless" menu and select "Print Network Configuration" or "Print Wireless Configuration." The page that prints will include the IP address of the printer, as well as other network information. You can also find the IP address through the printer software on your computer.
