  required String caption,
  BarcodeType type = BarcodeType.code128,
  int height = 100,
  int width = 2,
  bool showBarcodeText = true,
}) async {

    final barcodeResult = await printBarcode(
      data,
      type,
      height: height,
      width: width,
      alignment: Alignment.center,
      textPosition: showBarcodeText
          ? BarcodeTextPosition.below
          : BarcodeTextPosition.none,
    );

    if (!barcodeResult) {
      return false;
    }

    // Then print the caption (using imported PrinterText)
    return await PrinterText.printCenteredText(
      text: caption,
      fontSize: 20,
    );
  } catch (e) {
    print('Error printing barcode with caption: $e');
