Network virtual printers

[bigwillyco]

I am working with an old legacy system (1980ish) that wants to print to a printer connected to an IP address. Basic Unix print stream nothing fancy. I would like to find a piece of software that would capture that incoming data and convert it into some sort of file (not too picky at this point, gif, tiff, txt, pdf). It must run autonomously, the software sending the print data just sends, no user interface to choose what printer, no way to prompt for output type.

Now to get really interesting and I may have to break out the Visual Net programming guide and make something to do this but who knows, someone might have built something like this already.

This software runs different reports to different IP addresses. In the days of single source paper printers the printing center would have different printers with different types of paper on each of the IP addresses. My initial idea was to put a PC on each of those IP addresses and run the capture software. I would love it if someone had a virtual server software that would simulate each of the IP's, run the data capture, create my files, and then dump them in a storage file for me to do with as needed.

Any ideas?
