- 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
