@override
Future<bool> printReceipt(String identifier, String interfaceType,
    Map<String, dynamic> printData) async {
  try {
    final bool result =
        await methodChannel.invokeMethod<bool>('printReceipt', {
              "identifier": identifier,
              "interfaceType": interfaceType,
              "printData": printData, // Pass the data for the receipt
            }) ??
            false;

    return result;
  } catch (e) {
    debugPrint("Error printing document: $e");
