'Selfle' might be the buzzword of the moment, but Canon's been using it to brand photo printers for a decade or so (albeit spelt differently). Like previous models, the Selphy CP910 is an extremely compact printer that's designed specifically for printing postcard or credit-card size photos, as well as mini stickers. It supports wireless networking, has a colour screen, and you can print without a computer simply by plugging in USB sticks or SD cards. The CP910 is unusual in that it prints using dye sublimation instead of laser or inkjet technology. In a dye-sub printer, a ribbon of solid dye is heated, turning the dye to a gas that solidifies again on the cool paper passing underneath. The paper passes through three times initially, taking on the yeEow, magenta and cyan dye to build up a finished image, before a clear protective coating is added on a fourth pass. It's a fast process and the results are completely free of grain, making it ideal for photos. However, there is a distinct a lack of sharpness when compared to high-quality inkjet prints and a greater propensity for fading compared to prints from high-end photo inkjets using pigmented inks.
