Don’t think this is just a traditional book. Once you flip the front cover, you will find more incredible functions, this is a book shaped portable printer.
The book styled printer is designed by Moonhwan Park, a designer from South Korea. The Book Printer measures 50 X 257 X 182 mm, and comes with Bluetooth technology, so you can conveniently connect your iPhone, iPad, and other Bluetooth-enabled devices with the printer. Whenever you want, you can pull out the portable printer and print out photos or documents.
Unfortunately, Book Printer is still a design concept. We have no idea whether the incredible compact printer will become reality.
