During CES 2014 which ended a week ago, Fujifilm introduced the instax SHARE SP-1 – a small portable instant printer which connects to your mobile device and allows you to print small Polaroid-like prints.
Luke Westaway from CNET had this very quick look at the instax SHARE during the show which can print up to 20 images using a replaceable cartridge which will cost between $15-$20 to replace (so we are looking at $1 or less per print). The unit itself will cost just under $200.
