My office has 3 printers that currently are able to be accessed only by parallel interface. We'd like to keep our LAN simple if possible by hooking all of the printers to our RHEL4 machine so that we can run the printers with CUPS from there. The RHEL4 machine, though, has only a single parallel port available.

As I understand it, this situation calls for a device which can multiplex the parallel port as depicted here. My questions to the forum are these:
* Has anyone multiplexed or is anyone currently multiplexing a parallel port with the parport module successfully?
* If so, what is the manufacturer and model of the multiplexor device that you use?
