Network Basics 56
TCP/IP and IP Addresses
If your computer is on a large network, contact your network administrator for the appropriate TCP/IP
addresses and additional system settings information.
If you are creating your own small Local Area Network or connecting the printer directly to your
computer 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 that
the addresses are similar, but not the same; only the last digit needs to be different. For example, your
printer can have the address 192.168.1.2 while your computer has the address 192.168.1.3. Another
device can have the address 192.168.1.4.
Many networks have a Dynamic Host Configuration Protocol (DHCP) server. A DHCP server
automatically programs an IP address into every computer and printer on the network that is
configured 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 IP
addressing.
