Re: Hacking the Xaar 128 printhead
Well, since we all have spent so much time on stupid print heads, I have decided to reverse engineer the protocol of an industrial printhead. Sure, it's 200 Euros for a single head in a single color at only 200 dpi, but these babies are industrial strength, giving them supposedly a much longer life...
