This ‘Little Printer’ thing is making the rounds today (right). It is a cute $259 (plus $30 shipping to U.S.) Cloud printer that prints on a receipt-size roll of paper from a smartphone using some special software.
I am not feeling it, but I imagine there will be some special use cases. As The Verge notes in an interview with Berg cofounder Matt Webb, you could put one of these at your grandma’s house and just send her black and white notes/receipts all day. You can even have it set up to print news on a smartphone-sized scroll of paper. :/
