Printer-based lpd Configuration
lpd/lpr is an implementation of the standard UNIX line printer daemon. It
lets you print across a TCP/IP network without needing to install software
on your workstation. All filtering and banners are done by the Network
Card. Remote printing uses the same commands (lpr, lpq, lpc) as local
printing.
An lpr request from a workstation references the remote (rm) entry in the
/etc/printcap file, where it finds the printer on a remote system. lpr opens
a connection with the network lpd/lpr process on the remote system, and
sends the data file to the remote printer. The printer-based lpd then filters
the data and prints the job in accordance with information contained in the
control file and its own printcap file.
The Network Card lpd recognizes the format of certain printer emulations
and filters the data, if possible, so it can be printed on the printer type you
specify. Either of the following two methods can be used to inform the Net-
work Card lpd of what type of printer is connected.
1. Using the default port setting (PCL, PostScript, etc.)
2. Using Telnet or the Network Card HTML settings page to change the
listed emulation types (Network Card HTML settings page can be ac-
cessed using MAP or a Web browser.)
The following sections describe how to give specific lpd/lpr setup instruc-
tions for various systems.
