The rlprrc configuration file is consulted by the remote
printing commands (rlpr(1), rlpq(1), and rlprm(1))
to resolve a printqueue or a hostname. It can be used to either lookup
a printqueue (printer) for a given host, or a host for a given
printqueue. If both the printer and the printhost are known, this
file is never consulted.
Initially, the remote printing commands look for the file .rlprrc
in the users home directory. If that file cannot be found or does
not provide the information necessary to resolve the query, then
the system-wide /usr/local/etc/rlprrc is consulted (if present).
If resolution is still unsuccessful, the command fails.
There is one entry per line - each line has the format:
hostname: printer1 printer2 ... printerN
Which indicates that host hostname has printers printer1
printer2 ... printerN available. In the case where the remote
printing command knows the host to print to but does not know which
printer to use on that host, the first one (printer1 here) will
In the case where the remote printing command knows the printqueue
(printer) to print to but does not know what host has that queue, the
last host which has the specified printqueue is used. If this
behavior is not acceptable, you can force a certain host to always be
used for a certain printqueue by putting a ! after the
For example, an .rlprrc file containing:
foo.baz.org: litho laserjet4!
foo.bar.org: laserjet4 lineprinter
will always resolve the printqueue laserjet4 to
foo.baz.org no matter what other hosts have a printqueue named
The rlprrc file is only consulted in situations where a
printqueue or hostname needs to be resolved. It is provided only for
convenience and is not required.
