Hi Clem, why not implement RFC 1179? You wouldn’t need special software if this was an lpr network printer.

Hmmm… Challenge accepted!

Shouldn’t be that hard to implement since it exists since the dawn of the computer… er… almost… 1990.

I would give it a shot if only I could get my hands on a prototype

You can certainly give it a go!
Send me a DM with your adress , I have a spare PCB here that I could send to you. (you'd need to source the parts yourself though)

It's okay. I'll make my own. I'm sure someone else could benefit from your generous offer though. :-)
