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.
The -f option can be used to specify a different printer device, e.g.
/dev/usblp0.
The -i option can be used to specify binding to one address instead of
all interfaces which is the default.
The -b option turns on bidirectional copying.
The -v option shows the version number.
