}

Usage

import BluePrint from 'rn-bluprint-printer';

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

// Connect to a specific printer by its name
const connect = await BluePrint.connect(printerName);

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

// Retrieve a list of paired Bluetooth devices
const connectedDevices = await BluePrint.getPairedDevices();

Full Example

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

import { BluePrint } from 'rn-bluprint-printer';

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

    // Step 2: Get Paired Devices
    const pairedDevices = await BluePrint.getPairedDevices();
    console.log("Paired Devices:", pairedDevices);

    // Step 3: Connect to a Printer
    const printerName = pairedDevices[0]?.name || "YourPrinterName";
    const isConnected = await BluePrint.connect(printerName);

    if (isConnected) {
      console.log(`Connected to ${printerName}`);
      
      // Step 4: Print Data
      await BluePrint.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();
