I've never been a lover of adaptors for USB ports. The trouble with USB is that it tries to be 'all things to all men'. Most of the conversion work takes place in software and is prone to bugs and breakdowns. Parallel and serial ports were designed for specific purposes and trying to make them work like USB ports seems to me to be asking for trouble.
But that's just me. If they aren't to expensive it's worth a try.

Do you know that we're all in line for succession to the throne? Really?
Well, if forty-eight million, two hundred thousand, seven hundred and one people died I'd be Queen.
