Full description

This application acts as a powerful print service driver, allowing any web-based application (POS, Inventory, Order Management) to communicate directly with ESC/POS thermal printers connected to your Android device via Bluetooth or USB. Key Features: - Universal Connectivity: Support for both Bluetooth and USB ESC/POS or StarPRNT thermal printers. - WebSocket Bridge: Runs a local WebSocket server (default port 22300) on your Android device. Your web app simply connects to ws://localhost:22300 (or the device IP) to send print jobs. - Background Service: The app runs as a robust background service, ensuring your connection stays active even when the screen is off or the app is minimized. - Image Printing: Optimized for printing Base64 encoded images. Perfect for receipts, barcodes, and QR codes generated by your web app. - Cash Drawer Support: Send commands to open the connected cash drawer. - Paper Cut Support: Supports auto-cut commands for compatible printers. - Live Status: Real-time connection status monitoring for both the WebSocket server and the printer. - Diagnostics: Built-in tools to test connection and print quality. How it Works: - Connect: Pair your Bluetooth printer or plug in your USB thermal printer. Start: Open the app and start the WebSocket service. - Integrate: In your web application, connect to the WebSocket server running on the Android device. - Print: Send Base64 image data or ESC/POS commands from your web app to print instantly. Ideal For: - Web-based Point of Sale (POS) systems running on Android tablets. - Kitchen Display Systems (KDS) needing to print tickets. - Inventory management apps requiring label printing. - Any developer needing a bridge between a browser and a hardware printer. Technical Details: Default Port: 22300 Protocol: WebSocket (ws://) Data Format: Base64 Encoded Images / Raw ESC/POS Bytes Requirements: Android 5.0+ Bluetooth- or USB OTG-capable device ESC/POS-compatible thermal printer (58mm or 80mm) Tested Devices: - SEIKO SII RP-F10 - SEIKO SII MP-B20 - EPSON TM-m30 - MUNBYN TM-m30III - Star Micronics Mc-Print3
