Usage

import EvolutePrinter from 'rn-evolute-printer';

// Initialize the printer with callbacks for success and error handling
const initialize = await EvolutePrinter.initiate(
  errorCallback,
  successCallback
);

// The printerName is retrieved using the react-native-ble-manager package.
// Connect to a specific printer using its name.
const connect = await EvolutePrinter.connect(
  printerName,
  errorCallback,
  successCallback
);

// Print data, with optional success and error callbacks
const print = await EvolutePrinter.print(data, errorCallback, successCallback);

Full Example

Here’s a complete example to guide you through each step from initializing the library to printing data.

import EvolutePrinter from 'rn-evolute-printer';

const initializePrinter = async () => {
  try {
    // Step 1: Initialize the Printer
    await EvolutePrinter.initiate(
      (error) => console.error('Initialization Error:', error),
      () => console.log('Initialization Successful')
    );

    // Step 2: Connect to a Printer
    const printerName = pairedDevices[0]?.name || 'YourPrinterName';
    const isConnected = await EvolutePrinter.connect(
      printerName,
      (error) => console.error('connect Error:', error),
      () => console.log('connect Successful')
    );

    if (isConnected) {
      console.log(`Connected to ${printerName}`);

      // Step 3: Print Data
      await EvolutePrinter.print(
        'Hello, this is a test print!',
        (error) => console.error('Print Error:', error),
        () => console.log('Print Successful')
      );
    } else {
      console.error(`Failed to connect to printer: ${printerName}`);
    }
  } catch (error) {
    console.error('Error:', error);
  }
};

// Initialize and run the example
initializePrinter();
