Meet the droPrinter: a portable printer designed specifically for your phone. It connects to your smartphone via Bluetooth and lets you print shopping lists, notes, messages, images, and everything in between using thermal paper. The device does not need ink and can be set up easily.
Here is how the droPrinter works: the printer head heats the thermal paper to print what you want. Did we mention that the device serves as a smartphone charger? More information is available on Kickstarter.
