Network Connection
Theory
To connect your printer in a 
TCP/IP network environment, 
you must make sure that the 
internal network addresses in 
the printer have been set.

Making the Connection
Ethernet Interface
An RJ45 connector can be used as the Ethernet interface for this printer.
When connecting your printer to an Ethernet network, the tasks you perform 
depend on how you plan to set the printer’s IP (Internet Protocol) address.
Since the IP address for each PC and printer on your network must be 
unique, you usually need to modify this preset address so it doesn’t conflict 
with any other IP address or your network or any attached network. You can 
do this in one of two ways. Each is explained in detail in the following 
sections.
„Using DHCP
„Setting the address manually
Using DHCP
If your network supports DHCP (Dynamic Host Configuration Protocol), the 
printer’s IP address will be automatically assigned by the DHCP server when 
you turn on the printer. (For a description of DHCP, see the Network Printing 
section in the Phaser 6120 Reference Guide on the Software and 
Documentation CD-ROM.)
If your printer is not automatically assigned an IP address, verify that 
DHCP is enabled on the printer (
MENU > PRINTABLE PAGES 
MENU > CONFIGURATION
). If it is not enabled, you can enable it in 
the 
MENU > CONNECTION SETUP > NETWORK SETUP > 
TCP/IP > DHCP/BOOTP
 menu.
1Connect your printer to the network. 
Using an Ethernet cable, plug the RJ45 connector into the Ethernet 
interface port of the printer.
2Turn on your PC and printer.
3When the printer’s message window displays READY, install the printer 
driver and utilities.

Setting the Address Manually
You may also manually change the printer’s IP address, subnet mask, and 
gateway by using the following instructions. (For more information, see 
Understanding the Ethernet Configuration Menus in the Phaser
 6120 
Reference Guide on the Software and Documentation CD-ROM.) 
When the IP address is changed, add a new port or reinstall the 
printer driver.
CAUTION
You should always notify the network administrator before changing the 
printer’s IP address.
1Turn on your PC and printer. 
2When the printer’s message window displays READY, set the IP address.
aSelect Connection Setup, and then press the Menu/Select key.
bSelect Network Setup, and then press the Menu/Select key.
cSelect TCP/IP, and then press the Menu/Select key.
dSelect IP Address, and then press the Menu/Select key.
eUse the Up and Down keys to select the IP Address.
fUse the Right and Left keys to move to the next set of numbers.
gRepeat Steps e and f until you have selected the entire IP Address.
3If you do not need to set the subnet mask or gateway, go to step 5. 
 
To set the subnet mask, but not the default router, go to step 8. 
 
To set the default router, follow these steps.
aSelect Default Router, and then press the Menu/Select key.
bUse the Up and Down keys to select the Default Router numbers.
cUse the Right and Left keys to move to the next set of numbers.
dRepeat Steps and b and c until you have selected the entire Default 
Router number.

4If you do not need to set the subnet mask, go to step 5. 
 
To set the subnet mask, follow these steps.
aSelect Subnet Mask, and then press the Menu/Select key.
bUse the Up and Down keys to select the Subnet Mask numbers.
cUse the Right and Left keys to move to the next set of numbers.
dRepeat Steps and b and c until you have selected the entire Subnet 
Mask number.
5Save your configuration changes and make the printer ready for printing 
again.
6Press the Up key until the menu displays READY.
7Print a configuration page to verify that the correct IP address, subnet 
mask, and gateway have been set.
aSelect Printable Pages, and then press the Menu/Select key.
bSelect Configuration, and then press the Menu/Select key.
cPress the Menu/Select key.
8When the printer’s message window displays READY, install the printer 
driver and utilities.

Network Printing
The Phaser 6120 printer supports the following network protocols:
„BOOTP
„DHCP
„HTTP
„IPP
„LPD/LPR
„SLP
„SNMP
„Port 9100
„SMTP
This chapter defines each of these protocols and then explains how to print 
via IPP.
BOOTP
BOOTP (Bootstrap Protocol) is an Internet protocol that enables a diskless 
workstation to discover (1) its own IP address, (2) the IP address of a BOOTP 
server on the network, and (3) a file that can be loaded into memory to boot 
the workstation. This enables the workstation to boot without requiring a hard 
or floppy disk drive. 
DHCP
DHCP (Dynamic Host Configuration Protocol) is a protocol for assigning 
dynamic IP addresses to devices on a network. With dynamic addressing, a 
device can have a different IP address every time it connects to the network. 
In some systems, the device’s IP address can even change while it is still 
connected. DHCP also supports a mix of static and dynamic IP addresses. 
Dynamic addressing simplifies network administration because the software 
keeps track of IP addresses rather than requiring an administrator to manage 
the task. This means that a new computer can be added to a network without 
the hassle of manually assigning it a unique IP address.

HTTP
HTTP (HyperText Transfer Protocol) is the underlying protocol used by the 
World Wide Web. It defines how messages are formatted and transmitted, 
and what actions web servers and browsers should take in response to 
various commands. For example, when you enter a URL in your browser, this 
actually sends an HTTP command to the Web server directing it to fetch and 
transmit the requested web page. 
IPP
IPP (Internet Printing Protocol) is a protocol for end users’ most common 
printing situations over the Internet. It allows users to find out about a printer’s 
capabilities, submit print jobs to a printer, determine the status of the printer 
or print job, and cancel a previously submitted print job.
LPD/LPR
LPD/LPR (Line Printer Daemon/Line Printer Request) is a platform-
independent printing protocol that runs over TCP/IP. Originally implemented 
for BSD UNIX, its use has spread into the desktop world and is now an 
industry standard. 
SLP
Traditionally, in order to locate services on the network, users had to supply 
the host name or network address of the machine providing the desired 
service. This has created many administrative problems. 
However, SLP (Service Location Protocol) simplifies the discovery and use of 
network resources such as printers by automating a number of network 
services. It provides a framework that allows networking applications to 
discover the existence, location, and configuration of networked services.
With SLP users no longer need to know the names of network hosts. Instead, 
they need to know only the description of the service they are interested in. 
Based on this description, SLP is able to return the URL of the desired 
service.

Unicast, Multicast, and Broadcast
SLP is a unicast and a multicast protocol. This means that messages can be 
sent to one agent at a time (unicast) or to all agents (that are listening) at the 
same time (multicast). However, a multicast is not a broadcast. In theory, 
broadcast messages are heard by every node on the network. Multicast 
differs from broadcast because multicast messages are only heard by the 
nodes on the network that have joined the multicast group. 
For obvious reasons network routers filter almost all broadcast traffic. This 
means that broadcasts that are generated on one subnet will not be routed 
or forwarded to any of the other subnets connected to the router (from the 
router’s perspective, a subnet is all machines connected to one of its ports). 
Multicasts, on the other hand, are forwarded by routers. Multicast traffic from 
a given group is forwarded by routers to all subnets that have at least one 
machine that is interested in receiving the multicast for that group. 
SNMP
SNMP (Simple Network Management Protocol) is a set of protocols for 
managing complex networks. SNMP works by sending messages to different 
parts of a network. SNMP-compliant devices, called agents, store data about 
themselves in Management Information Bases (MIBs) and return this data to 
the SNMP requesters.
Port 9100
When printing through a network, TCP/IP port number 9100 can be used to 
send raw data.
SMTP
SMTP (Simple Mail Transfer Protocol) is a protocol for sending email.
This protocol was originally used to send email between servers; however, 
currently client email software uses it to send email to servers using POP.
