The HP Photosmart 422 is a photo printing package that provides am all-in-one solution for instant taking and printing of photos. In addition to the printer itself the Photosmart 422 comes with an HP Photosmart M415 5.8 mega pixel digital camera, thus giving you a straight out of the box instant photo studio. As for the Photosmart 422 it is PC and MAC compatible and works standalone via the camera when placed in the docking port on top. The printer itself also can connect to your TV for picture viewing. You can directly print and edit from the camera and its 1.5 inch color LCD screen. The 422 also has an optional battery for on the go printing and the camera can also recharge when docked to the printer. The prints are surprisingly on par with quality non portable photo printers, although its still only borderless 4 x 6 color photos at 4,800 x 1,200 dpi. It does have a swift one and a half minute per 4 x 6 photo rate. The printer uses a single Tricolor HP 95 Vivera ink cartridge and accepts optional Gray Photo HP 100 Vivera ink cartridges for black and white printing. The only real drawback here is the lack of compatibility with any other camera but the included one for direct printing, but if that’s not an issue for you than the Photosmart 422 is an attractive package.
