Ethernet Interface Setup Guide
Ethernet terminology and default setup
For the printer to operate with Ethernet, a series of commands must be set within the printer. These commands can only be
set through the host computer and are not configurable through the printer configuration menu.
Default setup instructions and sample Ethernet diagnostic printout are on the following page. Note the differences between
an Ethernet and a standard RS-232C printout.
Ethernet Terminology
Before making command settings, review the following description of terms to fully understand their intended meaning.
MAC address
a unique hexadecimal serial number assigned to each Ethernet network device to identify it on the
network. Each printer communication board gets a unique number from TPG’s assigned range of numbers. TPG numbers
start with: 00:E0:70.
IP address
a unique number that identifies each node on a network and to specify routing information. Each node
must be assigned a unique IP address. The address is made up of two distinct parts: a network ID, which identifies the
network; and a host ID, which is typically assigned by the administrator. These addresses are typically represented in
dotted-decimal notation, such as 138.58.11.27. The default setting is: 192.0.0.192
Net mask
a series of bits designed to “mask” certain portions of an IP address and is used primarily for subnetting.
The standard netmask for a Class C network is 255.255.255.0, with the last octet (.0) directing the host to look there for the
machine number. The rest (255) is the network number. The default setting is 0.0.0.0. The net mask is used to determine if
a gateway is needed to reach an address.
Gateway
a hardware or software set-up that translates between two dissimilar protocols. A gateway, even when
the printer is on another subnet, is not always needed. The printer initiates no connection and obtains the gateway address
from the host packets. The default setting is 0.0.0.0 (none)
LP Daemon
an Ethernet protocol. The LP Daemon listens on port 515. Default is LP Daemon disabled.
Telnet Daemon a protocol for remote computing on the Internet. It allows a computer to act as a remote terminal on
another machine, anywhere on the Internet. This means that when you telnet to a particular host and port, the remote
computer (which must have a telnet server) accepts input directly from your computer (which must have a telnet client)
and output for your session is directed to your screen. The telnet server listens on port 23. The default setting is enabled.
Raw TCP/IP Port
enables the printer to listen for raw TCP/IP communications. Specifying this to zero will disable raw
TCP/IP connections. Default value is 9001 enabled.
BootP
a TCP/IP network protocol that lets network nodes request configuration information from a BOOTP
“server” node. Use BootP to obtain the IP address at power-up. Default setting is disabled.
DHCP
allows “leasing” of IP address for a limited time. If no IP address is found at start-up, the printer
waits for two more minutes. If no address is found after two minutes DHCP will automatically set the default IP address.
Default: enabled
