The Pringo P231 Portable Photo Printer delivers mobile printing for your smartphone by using WiFi connectivity for peer-to-peer networking with your devices. The wireless connection is made using a free smartphone application available for iOS and Android. The application also features photo editing functions, beautiful borders and colourful stamps allowing you to enhance your images before printing. In order to stay lightweight and portable, the Pringo printer uses a dye sublimation process to transfer ink. This is contained in a special ribbon assembly cartridge designed for the Pringo. The ribbon prints 10 borderless 2.1 x 3.4″ images before requiring replacement. The internal paper tray also holds 10 sheets. Each quality print features a resolution of 290 dpi and is created in approximately 65 seconds. The printer is powered by a re-chargeable 550mAh lithium-polymer battery. Your Pringo Printer will be delivered with a battery charger, 10 paper sheets and one dye ribbon cartridge.
