Just for completeness sake, there was also a successful RailsConf Europe in London, and a well-received Rails Underground too. I therefore assume that 'full scale' must mean something quite specific. Anyway, as I said, orthogonal.
I'm aware of and not fan of the gravitational well that London influences, and definitely agree that it would be great to have events all over the UK. It's a shame that BritRuby isn't going ahead, whatever the reasons.
If you look at the Arduino code (https://github.com/freerange/printer/blob/master/printer.ino), all it does is download a stream of bytes, doing some very rudimentary validation (Content-length), and then sending the bytes out on a serial port.

There's also some fairly comprehensive documentation on the github wiki, including an architectural overview, and building your own printer: http://github.com/freerange/printer/wiki
