This portable, wireless photo printer was judged The Best by The Hammacher Schlemmer Institute because it produced the most vibrant pictures and was easiest to use. Institute analysts printed identical smartphone photos on each test printer and The Best model consistently output pictures with vivid colors that most closely matched the original, unlike lesser units that produced blurry, washed out images with streaks. In about a minute, it prints vibrant, 300-dpi resolution 3 3/8" x 2 1/8" pictures using a special paper imbedded with colored dye crystals, with a protective coating that makes photos waterproof, fingerprint-proof, and fade-resistant. The pocket-size printer pairs easily with a smartphone without requiring a wireless network, and its free app lets users add creative filters and special effects. Its rechargeable battery provides 20 minutes of power on a 90-minute charge from the included microUSB cable. Includes photo cartridge that makes 8 prints. White. 1" H x 3" W x 6" L. (14 1/2 oz.)
