Welcome to your Expo app 👋

This is an Expo project created with create-expo-app.

Get started

1. Install dependencies

   npm install

2. Start the app

   npx expo start

In the output, you'll find options to open the app in a

• development build
• Android emulator
• iOS simulator
• Expo Go, a limited sandbox for trying out app development with Expo

You can start developing by editing the files inside the app directory. This project uses file-based routing.

sisilagip

SisiLagip 📸 SisiLagip is an offline photo booth app built for Android tablets. It lets you take photos, pick a fun template, and instantly print them as black-and-white receipt-style photos using a USB thermal printer. No internet needed. Just snap, pick a design, and print.

Test a USB thermal printer

Direct USB access uses the local Android module in modules/usb-thermal-printer, so it does not work in Expo Go.

1. Install the native Android build with npm run android.
2. Connect an ESC/POS-compatible thermal printer to the Android device using USB OTG.
3. Open a photo preview and press Print This!.
4. Allow the Android USB permission prompt.

The app composes the selected photo layout as a 384-dot black-and-white receipt, sends it with ESC/POS raster commands, and then cuts the paper.
