LPR UNIX Host Setup

3. TCP Socket Connections
The RapidPrint 500 supports direct TCP connections to its ports. These
connections provide 8-bit clean full-duplex data communication. They do
require that the user provide his or her own software. The RTEL software
includes an example program showing how to form these connections. Note that
the TCP Socket interface does not support queueing. If the resource is busy when
a connection attempt is made, the connection will be rejected.
10.2 LPR
LPR is supported on many machines, and is simple to configure for the RapidPrint 500. Add the
host print queue name into /etc/printcap, and then specify the remote nodename (the host name of
the RapidPrint 500) and the service name on the RapidPrint 500.
NOTE: There are slight variations in LPR configuration for AIX, HP, SCO UNIX,
Solaris, ULTRIX, and Windows NT hosts; after reading this section, refer to the
following sections for platform-specific configuration information.
NOTE: Windows 95 does not support LPR directly, but there are third-party solutions
available.
To add a print queue for a RapidPrint 500, add the RapidPrint 500’s name and IP address to the
host’s /etc/hosts file.
Edit the /etc/printcap file and add an entry of the following form:
Figure 10-1: Example printcap File Entry
Note that the punctuation shown is required, and whitespace should be avoided within each
option. The example above creates a queue named RP_PRT. The rm parameter is the name of the
RapidPrint 500 in the host’s address file, the rp parameter is the name of the service as it exists on
the RapidPrint 500, and the sd parameter specifies the name of the directory used to hold tempo-
rary spooling files.
Create the spooling directory using the mkdir command, and make sure it is world-writable.
Figure 10-2: Creating a Spooling Directory
The mx option may be used to allow unlimited size files to be printed, and the sh (suppress
header) option may be used to prevent header pages from being generated. See the host’s docu-
mentation or man pages for more information on the format of the printcap file and how to create
the spool directory.
