You can get an HP printer's IP address by printing the network setup page, going to the printer's internal web server, or looking at the DHCP client list on your router. Press and hold the printer's wireless button until the wireless light begins flashing to print a network setup document. Enter the printer's IP address into a web browser to access the internal web server. Log into your router's web browser and search for the connected device's IP address to check the DHCP client list.
