6. UNIX System Network
6.1 Introduction
The print server is available for TCP/IP printing by Unix LPD (Line Printer Daemon) protocol. The LPD
protocol originated with Unix release is based on the BSD version of Unix and supported under most
versions of Unix.
This chapter explains how to configure the print server for TCP/IP operation, and how to modify
configuration files on your Unix system to allow printing to the print server. The configuration examples
in this manual follow the syntax for BSD based Unix systems.
Please refer to the related system documentation for the correct syntax of your systems.
To configure the print server for LPD printing, perform the procedures below:
1. Enable Print Server’s TCP/IP Support.
2. Set up Print Server’s IP address.
3. Verify Print Server’s IP Address.
4. Configure remote LPD printing on the host.
5. Print a test page.
In the next sections, we will describe these five procedures step by step.
6.2 Enable Print Server’s TCP/IP Support
The default configuration of the print server is with TCP/IP support enabled. Anyway, you can configure
the print server to enable TCP/IP support using the configuration program.
6.3 Setup Print Server’s IP Address
The print server must have a unique IP address in order to be recognized by the network.
You can set up the IP address on the various Unix systems using any one of the following methods:
1. DHCP (Dynamic Host Configuration Protocol)
2. BOOTP (Bootstrap Protocol)
The print server will use the last three methods to obtain its IP address automatically if its IP address is
configured as Auto (0.0.0.0).
6.3.1 DHCP
There are many Unix systems that support DHCP protocol, and the procedures to configure the DHCP
server database are different. This manual does not describe the DHCP server configuration on the Unix
systems. It is highly recommended that the DHCP server should be located on the same network as the
print server.
6.3.2 BOOTP
If you have the BOOTP daemon, bootpd, running on your UNIX system that is accessible by the print
server, you can use the BOOTP protocol to set up the IP address of the print server. We recommend that
the BOOTP server should be located on the same subnet as the print server. If you use Network
Information Services (NIS) in your system, you may need to rebuild the NIS map with the BOOTP services
before doing the following BOOTP configuration. To rebuild the NIS map, please refer to your system
documentation.
