In this week's Disruptors episode, I visit Zink in Waltham, Mass. Zink is a spin-off from Polaroid that has developed an inkless printing technology. The ink is in the paper in the form of special dye crystals that turn different colors when heated. By getting rid of the ink cartridges and associated printer heads, this will allow for the creation of compact, mobile printers that can be embedded into digital cameras, laptops, and even cell phones. Watch the video.
