I have an old piece of a hardware that does diagnostics on medical equipment. It prints out results over a parallel port. Is there any way to have CUPS accept jobs from a parallel port and redirect them to the default printer?

Essentially I want CUPS to listen to /dev/lp0 for incoming jobs.

Reading about this problem a bit, would it be possible for me to capture the PCL data via the parallel port (cat /dev/lp0 > out.pcl) and then convert it to Postscript using pspc16 or somehow send the PCL to Ghostscript to interpret the PCL and dispatch to CUPS?

  Not clear on the question, are you saying the hardware has a parallel port, normally you would connect directly to a printer, but you would like to connect to a different machines parallel port and use the CUPS service on that machine?

  I think you need a special cable, parallel ports aren't wired symmetrically (I'm not sure a crossover cable would be enough: some pins aren't wired inside the computer). There are two parts to your problem: getting the data from the diagnostics equipment to your computer's parallel port, for which you'll find more expertise on Super User, and routing the data from the parallel port to CUPS, which this site should address best.

This is not possible with a PC alone the parallel port is not designed to act as a printer.

You will need some sort of hardware that emulates a printer and then relays the data to the computer.

This page describes the sort of product you need. I don't know anything about that specific company.

Another option option might be a parallel to serial converter and then connect that to your PC.

  Why can't the PC do this in software? There has to be some kind of project that tackled this, the technology is like 40 years old. I mean, you're telling me if I want to turn a Linux box into an LPT printer, I'm SOL? This sounds like a popular request.

  For the cable, see Laplink (null-printer) cable. For the software... I don't know but you will probably be operating on /dev/parport* (the raw parallel port device) instead of /dev/lp* (specifically made for talking to a printer, not pretending to be one)
