how to obtain ip address for a network printer To obtain an IP address for your printer, plug your printer into an Ethernet connection via a router or other connection. The printer will automatically obtain the first available IP address in the DHCP pool. The best way to know the IP address is to get the printer to tell you what the address is by printing out a network configuration printer report. You can even look at the DHCP server itself to quickly see the IP address of the Pinter.
