Putting it behind the USB is adding a lot of overhead

A 2012 computer should have plenty margin for emulating a 1980's parallel port, despite some USB in between. Not that I have tried it. Give it a try, I really think it will work just fine.

You won't find a computer with a parallel port nowadays. The one I use is from 2005 and I keep it just for eventual firmware updates.

Reply #3 - 03/17/12 at 09:00:22 Thanks, I do have an old PC I can probably get running, I proudly made up the cable then pulled my PC away from the wall to plug in and .... ah, no printer port!
