DESCRIPTION:=A small non-spooling printer server.\\\
|
||||||
|
p910nd is a small daemon that copies any data received on \\\
|
||||||
|
the port it is listening on to the corresponding printer \\\
|
||||||
|
port. It is primarily intended for diskless Linux hosts \\\
|
||||||
|
running as printer drivers but there is no reason why it \\\
|
||||||
|
could not be used on diskful hosts. Port 9100 is copied \\\
|
||||||
|
to /dev/lp0, 9101 to /dev/lp1 and 9102 to /dev/lp2. The \\\
|
||||||
|
default is port 9100 to /dev/lp0.
