This is truly interesting. It's amazing how Mindstorms can be used to develop it. I'm not sure how practical it will be as the author has mentioned it's currently capable of printing 1 char/5-7 seconds. So that might be too slow. But kudos to him to develop a solution; to think out of the box. Kudos to Lego to offer a tool to let dreamers build.
