Complete walkthrough for downloading, pairing, and configuring the miniprt companion app on smartphones and tablets for first-time users.
Before You Start
Ensure your miniprt portable mini printer is fully charged. A full charge takes about 90 minutes via USB-C and supports printing 10+ rolls of thermal paper. Check that your phone runs iOS 12+ or Android 8+ with Bluetooth 4.0 or higher.
Step 1: Download the App
Search for "miniprt" in the Apple App Store or Google Play Store. The app icon shows a white printer on a blue background. File size is approximately 45 MB. Download over WiFi to avoid mobile data charges.
Step 2: Power On and Pair
Press and hold the power button on your mini printer for 3 seconds. The LED indicator flashes blue. Open your phone's Bluetooth settings and look for a device named "miniprt-XXXX". Tap to pair. Default PIN is 0000 if prompted.
Step 3: Connect in the App
Open the miniprt app. Tap the Bluetooth icon in the top-right corner. Your paired printer should appear in the device list. Tap it to connect. A green "Connected" status confirms successful pairing.
Step 4: Load Thermal Paper
Open the paper compartment by sliding the top cover. Insert a roll of 57mm x 30mm thermal paper with the printable side facing up. Pull out about 1cm of paper and close the cover firmly until it clicks.
Step 5: Test Print
In the app, tap the "Test Print" button in Settings. The printer should feed paper and print a test pattern showing the connection status, battery level, and firmware version.
Troubleshooting Common Issues
- Printer not found: Ensure no other app is connected to the printer. Close all Bluetooth apps and restart the pairing process.
- Faint print: Check that you are using high-quality thermal paper rated for 200+ DPI printing. Cheap paper produces lighter output.
- Paper jam: Open the cover, remove the roll, check for torn paper bits, and reload.
