Code128 Barcode is not rendering correctly

[jchathu]

If we print the code 128 barcode as same as using this method printer.Code128("123456789");
It will print wrong barcode. It will print something like this "495051525354555657" after scanning the printed barcode

Is there anyway to decode this or how can we correct his for Code128 barcodes?

I just extracted this from here and it works for me

    private byte[] BarcodeBytes(string barcode)
        {
            byte type = 0x49; //CODE128
            byte gs = 0x1D;
            byte printBarcode = 0x6B; 
            byte code = 0x42; //CODE_B

            barcode = barcode.Replace("{", "{{");
            barcode = $"{(char)0x7B}{(char)code}" + barcode;

            var command = new List<byte> { gs, printBarcode, (byte)type, (byte)barcode.Length };
            command.AddRange(barcode.ToCharArray().Select(x => (byte)x));
            return command.ToArray();
        }

Use it with

var printer = new USBPrinter.Printer("printer-name", "utf-8");
printer.Append(BarcodeBytes("123456789"));
