Then install the PrintX Pro program on your Android or iOS device from the Google Play Store or the Apple App Store, respectively.
Open the app and turn the printer on and print the QR code immediately.
The app prompts you to check the QR Code, which then pairs the two devices and the program with the printer via Bluetooth 4.0.

After locating and connecting to your printer, the PrintX Pro app opens to your home screen, ready to print.
