Printer Connection and Software Installation 74 TCP/IP and IP AddressesIf your computer is on a large network, contact your network administrator for the appropriate TCP/IPaddresses and additional system settings information.If you are creating your own small Local Area Network or connecting the printer directly to yourcomputer using Ethernet, follow the procedure for automatically setting the printer’s IP address.Computers and printers primarily use TCP/IP protocols to communicate over an Ethernet network.With TCP/IP protocols, each printer and computer must have a unique IP address. It is important thatthe addresses are similar, but not the same; only the last digit needs to be different. For example, yourprinter can have the address 192.168.1.2 while your computer has the address 192.168.1.3. Anotherdevice can have the address 192.168.1.4.Many networks have a Dynamic Host Configuration Protocol (DHCP) server. A DHCP serverautomatically programs an IP address into every computer and printer on the network that isconfigured to use DHCP. A DHCP server is built into most cable and Digital Subscriber Line (DSL)routers. If you use a cable or DSL router, see your router’s documentation for information on IPaddressing.
