I'd like to pipe data in and out to a lpt (parallel IEEE 1284) port on another machine, to remotely use a device. Can it be done in a common unix-y system? I have ubuntu 12.04. :)

I was thinking something like:

machine A, terminal 1:

nc -l 1234 > /dev/lpt0

machine B, terminal 1:

nc 192.168.1.100 1234 < /dev/lpt0

and on second terminals:

machine A, terminal 2:

nc 192.168.1.100 4321 < /dev/lpt0

machine B, terminal 2:

nc -l 4321 > /dev/lpt0

I don't know if this is a sound way to do this.

How to communicate with parallel ports remotely?

  • NOTE: I have not enough reputation to create the [parallel-port] tag, even if the description for [parallel] says it should be used.

  • Is there a reason why you don't use CUPS?

  • @SourceLab yes, it's me assuming that a cnc device wouldn't classify as a printer and thus unusable via cups.

Yes, it's posible - but not with the standard set of tools on a Linux installation. The simplest solution is to use the ppdev device driver and some custom code.
