I have several old computers. It's fun to print something with them. But printers are getting old too, and old printers are more likely to be thrown away than old computers.
I would like to use an arduino (Uno) to emulate and capture computer-to-printer output, and send it to a modern computer (via USB) in any useful format. That could be plain text, formatted text, or a real printstream than can be redirected to a modern printer. Doesn't matter, that's interpreting the byte-stream and programming as good as you can.
The difficulty is the first step, the hardware: capturing a parallel signal over different wires, and turning that back again into byte-data.
Obviously, I'm not the first one to think about that. And I have done some looking around. I've seen several questions and several answers, but so far, I haven't seen a finished project. (I might have missed it) I have seen a commercial product, but +€200 seems to be over the top.
- IS there a finished project, documented, that I can build ?
- if not, I'm open to suggestions.
My knowledge of electronics is minimal, but I'm pretty good in breadboardin.
