Simply send a single HTTP request, and the receipt prints instantly—no drivers, no SDKs, and no custom client-side code.

Suitable for web-based POS applications, queuing systems, kitchen displays, and even e-commerce integrations that require printing receipts to a local thermal printer.

▣ HOW IT WORKS
The app runs a lightweight HTTP server on port 9000. Other devices on the same network (LAN/Wi-Fi) simply send a POST request to the server address to print a formatted receipt. The app forwards the printout to your thermal printer via Bluetooth, USB, or IP.

▣ CONNECTION OPTIONS (TRANSPORT)
• Bluetooth (SPP) — pair the printer once, ready to go
• USB — support for USB Printer class (class 7) printers
• IP / Network — direct connection to IP-based printers (default port 9100, RAW/JetDirect)

▣ RICH RECEIPT FORMATS
The receipt layout uses simple, row-based markup, making it easy to integrate:
• Alignment & columns: left [L], center [C], right [R] — ideal for item + price lines
• Text styles: bold, underline, double underline
• Multi-level font sizes: normal, wide, tall, large, up to 7x
• Images (PNG base64), barcodes (EAN-13, EAN-8, UPC-A, UPC-E, Code128), and QR Codes
• Adjustable spacing to fit receipts across printer models

▣ FLEXIBLE SETTINGS
• Paper width: 58 mm (32 columns) or 80 mm (48 columns)
• Section spacing 0–6 lines
• Auto-cut (on/off)
• Cash drawer open (on/off)
• All settings are automatically saved and remain active after the application is closed

▣ SIMPLE INTERFACE
• Displays server URL and LAN IP, complete with copy button
• Real-time printer connection status indicator
• Test Print button to ensure printer is ready
• Log panel to monitor and debug print activity

▣ HTTP API
• GET /health — check server status
• GET /status — current printer transport & connection info
• POST /print — send receipt for printing (cut, drawer open, and spacing can be set per print)
- Responses are in JSON format with clear error codes, making it easy for developers to integrate.

▣ PERMISSION NOTE
On Android 12+, the app requests Bluetooth permissions (BLUETOOTH_CONNECT & BLUETOOTH_SCAN) upon first launch. These permissions are required to use a Bluetooth connection. The app also requires local network access to run the server.

Turn one device into a receipt printing bridge for your entire system — lightweight, fast, and ready to go. ## Rankings - #2,907,236 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.ACCESS_WIFI_STATE` - `android.permission.BLUETOOTH_CONNECT` - `android.permission.BLUETOOTH_SCAN` - `android.permission.CHANGE_WIFI_STATE` - `android.permission.FOREGROUND_SERVICE` - `android.permission.FOREGROUND_SERVICE_CONNECTED_DEVICE` - `android.permission.INTERNET` - `android.permission.POST_NOTIFICATIONS` - `android.permission.RECEIVE_BOOT_COMPLETED` - `android.permission.WAKE_LOCK` - `com.google.android.gms.permission.AD_ID` - `com.ketant.mobile.printer.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` ## Similar extensions and apps - [Printer Server](https://chrome-stats.com/d/net.sinergics.helper.printer) — 5 users - [Cleanter: Thermal Printer BT](https://chrome-stats.com/d/id.cleancode.cleanter) — 951 users - [POS Printer–thermal print app](https://chrome-stats.com/d/com.phucynwa.mini.portable.bluetooth.pos.printer) — 350,291 users, 4.13 / 5 - [Printzen Mobile Print Services](https://chrome-stats.com/d/com.mobileprint.service) — 141 users - [Astos Printer](https://chrome-stats.com/d/com.astos.printservice) — 97 users - [Receipt Printer Driver](https://chrome-stats.com/d/me.shadura.escposprint.plus) — 126,449 users, 4.25 / 5 - [POS Printer](https://chrome-stats.com/d/com.coolerproyt.ecsposprinter) — 32 users - [Bitehubs Autoprint](https://chrome-stats.com/d/com.xninesolutions.bitehubs.autoprint) — 11 users - [Receipt Printer APP](https://chrome-stats.com/d/com.receiptprintapp.receipt_print_app) — 30 users - [Santa Printer Service](https://chrome-stats.com/d/com.santajsc.santaprinter) — 54 users - [mPrintServer](https://chrome-stats.com/d/com.bixolon.mprintserver) — 8,705 users - [Basic Receipt Printer Driver](https://chrome-stats.com/d/me.shadura.escposprint) — 37,657 users, 3.40 / 5 --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.ketant.mobile.printer)
