What exactly is a book printer? It’s basically a machine that’s capable of creating “a bound paperback copy of any book in its memory in a matter of minutes.” Video after the jump.
It works via the extraordinarily low-tech method of combining a couple printers with a conveyor belt, some hot glue, and maybe a miter saw. You can find the first commercial version at the New York Public Library’s Science, Industry and Business Library
