Polaroid has unveilied its new Zero Ink mini-printer device for printing digital camera issues quickly on the move via USB or Bluetooth. The printer uses no ink whatsoever and prints out borderless 5 cm × 7 cm images with a sticky backing so pictures can be easily displayed.

 

The Zero Ink technology, dubbed ZINK, uses heat to produce an image on special paper, which Polaroid describes as “an advanced composite material with embedded yellow, magenta and cyan dye crystals, activated with 200 million heat pulses, in 30 seconds, in a single pass…With 100 billion crystals in a 2×3in (5 cm × 7 cm)  print, the paper is 100% inkless.”
