The Fujifilm Instax Square Link Smartphone Printer is designed to be used with Fujifilm Instax Square Instant Film. Your smartphone connects to the printer via Bluetooth 4.2 and also needs to be connected to the free-to-download Instax Square Link App. Within the app, you can choose from over 1600 graphics to add to your images prior to printing. These include frames, sketches, and stickers, or you can take advantage of Augmented Reality (AR) effects through a QR code printed on the film. Upon scanning the code, you'll be able to add birthday cakes, hearts, doodles, messages, and more to your print with your smartphone and the app. The Fujifilm Instax Square Link Smartphone Printer provides images with an 800 x 800 resolution and 256 colours for JPEG, PNG, HEIF, and DNG files.
