You have to download the “PicKit Printer” app from the Google Play or Apple store in order to connect to your printer via WiFi. You will always have to use the app to connect to PIX’s WiFi. From there, you do not need to use the photo app with PIX if your phone has a Bluetooth® print option. If it has this option, you can just send the photo to the PIX Photo Printer and print directly from your photos. If your device does not have this option, you will need to use the app.
