# react-native-brother-print

A React Native module for printing labels on Brother printers via WiFi and Bluetooth. Supports QL series and other Brother label printers.

## Installation

```bash
npm install react-native-brother-print
```

or using yarn:

```bash
yarn add react-native-brother-print
```

### Brother SDK Setup (Android Only)

This library requires the Brother Print SDK, which must be provided by your application due to licensing requirements.

1. Visit [Brother's Developer Program](https://developerprogram.brother-usa.com/sdk-download)
2. Register/Login and download the Brother Print SDK for Android
3. Extract the .aar file from the SDK
4. Create a `libs` directory in your app's android directory:
   ```bash
   mkdir -p android/app/libs
   ```
5. Copy the Brother SDK .aar file to this directory
6. Add the following to your app's `android/app/build.gradle`:

```gradle
android {
    // ... your existing android config
}

repositories {
    // ... your existing repositories
    flatDir {
        dirs 'libs'
    }
}

dependencies {
    // ... your existing dependencies
    implementation files('libs/BrotherPrintLibrary.aar')  // Use the actual filename of your .aar file
}
```

7. (Optional) If you placed the Brother SDK in a different location, you can configure the path in your app's root `android/build.gradle`:

```gradle
buildscript {
    ext {
        // ... your other ext properties
        brotherSdkPath = "${rootProject.projectDir}/some/path/to/libs" // Adjust this if you placed the SDK somewhere else
    }
    // ... rest of your buildscript
}
```

### iOS Setup

Run pod install:

```bash
cd ios && pod install
```

## Usage

### Print via WiFi

```javascript
import { printImageViaWifi } from "react-native-brother-print";

try {
  const ipAddress = '192.168.1.100';  // Your printer's IP address
  const modelName = 'QL-820NWB';      // Your printer's model name
  const imageUri = 'file:///path/to/your/image.png';  // Local file URI
  
  await printImageViaWifi(imageUri, ipAddress, modelName);
  console.log('Print successful');
} catch (error) {
  console.error('Print failed:', error);
}
```

### Print via Bluetooth

```javascript
import { printImageViaBluetooth } from "react-native-brother-print";

try {
  const modelName = 'QL-820NWB';      // Your printer's model name
  const imageUri = 'file:///path/to/your/image.png';  // Local file URI
  
  await printImageViaBluetooth(imageUri, modelName);
  console.log('Print successful');
} catch (error) {
  console.error('Print failed:', error);
}
```
