Example

Make sure to check the Ionic Angular example in the example folder.

1. Import the plugin

import { CapacitorThermalPrinter } from 'capacitor-thermal-printer';

2. Connect to printer

CapacitorThermalPrinter.addListener('connected', () => {
  console.log('Connected!');
});
await CapacitorThermalPrinter.connect({
  address: 'XX:XX:XX:XX:XX:XX',
});

You can also use the startScan method to discover nearby devices.

• On Android, only printers will be discovered.
• On iOS, all bluetooth devices will be discovered.

CapacitorThermalPrinter.addListener('discoverDevices', (devices) => {
  console.log('Discovered devices list:', devices);
});

await CapacitorThermalPrinter.startScan();

3. Print sample receipt

await CapacitorThermalPrinter.begin()
  .align('center')

  .image('https://raw.githubusercontent.com/Malik12tree/capacitor-thermal-printer/main/assets/Logo-Black.png')

  .bold()
  .underline()
  .text('The amazing store\n')

  .doubleWidth()
  .text('RECEIPT\n')
  .clearFormatting()

  .text('Item 1: $10.00\n')
  .text('Item 2: $15.00\n')

  .align('right')
  .text('Total: $25.00\n')

  .align('center')
  .qr('https://example.com')
  .barcode('UPC_A', '123456789012')
