HP showed off a new color printer for iPads and iPhones coming to market soon, the HP Officejet Pro. It'll be targeted at education and small businesses. HP also came out with Live Photo, an augmented reality app. Here's how it works: An HP iPad or iPhone app looks at a specially printed picture via the camera, and that picture turns into a video on the iPad or iPhone screen. Hidden videos on printed documents sound like something out of a James Bond movie. HP Officejet Pro cost: sub-$1,000.
