Trak is a tiny, bare-bones inkjet printer that sticks, limpet-like, to the back of a notebook computer. The bus powered peripheral has a detachable printer head which runs across the Trax like a monorail car. It's not apparent from the product shots just how you feed in the paper, but for low-throughput use (the occasional boarding pass, for instance) this might be small enough to be useful.
Our favorite part, though, is the accompanying rant from Yanko Design's Anthony James, who appears to share our views on inkjet printers:
Quite.
