Easy on the capitals there, seriously. You're PUNCTUATING every other WORD and it makes it ANNOYING to READ. People are just trying to help, and you ain't being too nice about it.
Doing a quick search for USB to Centronics, I can find that there are some solutions on the market. These don't say they are specifically for printers, and are likely the same sort of bit banging people are talking about here, just built into a cable. Do I know this for sure? No. Read up a bit from people who have bought them, and see if they've tried to use them for anything besides printers. If it shows up as a regular parallel port, and is capable of all the regular communications, any protected/long mode driver or program should be able to make use of it, as modern operating systems have things called hardware abstraction layers, although older Windows programs may or may not be doing stupid shit, who knows.
Also, just because that annoys me slightly, no people aren't buying up old computers for the parallel interfaces, they /definitely/ sell PCI and PCIe solutions for Centronics that are fully compatible with modern operating systems. The reason is that old PC collecting is getting quite popular now, myself an especial buyer. Computers have had Centronics ports on them up until the early 2000's, and they have had motherboard headers up until quite recently. I wouldn't even be surprised if you could find a brand new board with one on it, I know my Z97 board has one. If the worry is getting an old shitbox just for the Centronics interface, find the nearest black box Dell machine from the early 2000's, they are barely even worth anything to collectors at the moment, I'll even give you mine if you happen to live near Albany, NY, maybe you can stick FreeBSD on it.
