How to print images via USB printer

[shinxxxxwon]

I followed your example and tried printing via USB. Text was fine. But the image is output as text and the layout is messed up.

Does it not support image output by any chance?

I am attaching my source.

connect

_connect(int vendorId, int productId) async {
    bool? returned = false;
    try {
      returned = await flutterUsbPrinter.connect(vendorId, productId);
    } on PlatformException {
      //response = 'Failed to get platform version.';
    }
    if (returned!) {
      setState(() {
        connected = true;
      });
    }
  }

getDevice

_getDevicelist() async {
    List<Map<String, dynamic>> results = [];
    results = await FlutterUsbPrinter.getUSBDeviceList();

    print(" length: ${results.length}");
    setState(() {
      devices = results;
    });
  }

print

_print() async {
    try {
      // var data = Uint8List.fromList(
      //     utf8.encode(" Hello world Testing ESC POS printer..."));
      final ByteData bytes = await rootBundle.load('assets/images/1-1.JPG');
      final Uint8List list = bytes.buffer.asUint8List();
      await flutterUsbPrinter.write(list);
    } on PlatformException {
      print('no printing.');
    }
  }

please take a look the example in link below:
https://github.com/kechankrisna/esc_pos_utils
it will demonstrate on how to get list to write in printer port.

Is the package available only for esc/pos printer? Can it be used with laser printers?
