When building a string for sending to the printer RAW what encoding for the bytes of gif file should I use to convert to so that the printer understands what I am sending correctly ?

The target printer is a LP 2824

Here is the EPL we are trying to send:

Here is the QR Code image:

StringBuilder label = new StringBuilder();
            label.AppendLine("I8,A,001");
            label.AppendLine();
            label.AppendLine();
            label.AppendLine("Q204,024");
            label.AppendLine("q448");
            label.AppendLine("rN");
            label.AppendLine("S4");
            label.AppendLine("D7");
            label.AppendLine("ZT");
            label.AppendLine("JF");
            label.AppendLine("O");
            label.AppendLine("R21,0");
            label.AppendLine("f100");
            label.AppendLine("N");

            // QR Code
            var qrCode = "GW280,78,15,116,";

            var filePath = @"C:\Users\Greg\Downloads\Frame.png";
            byte[] bytes = new byte[1024];
            File.OpenRead(filePath).Read(bytes, 0, 1024);

            System.Drawing.Image image = System.Drawing.Image.FromFile(filePath);
            var rawBinaryString = ByteArrayToString(ConvertToRawBinary(image));

           qrCode += rawBinaryString;
            label.AppendLine(qrCode);

// Time of printing
            var timeLine = "A388,53,2,3,1,1,N,";
            timeLine += "\"" + DateTime.Now.ToShortTimeString() + " - " + DateTime.Now.ToShortDateString() + "\"";

            label.AppendLine(timeLine);

            // Product Short Name
            var shortName = "A264,183,2,4,1,1,N,";
            shortName += "\"ORing - 22MM\"";

            label.AppendLine(shortName);

            // Serial #
            var serialNum = "A262,119,2,1,1,1,N,";
            serialNum += "\"GHG6547324KL990656\"";

            label.AppendLine(serialNum);

            var labelToPrint = label.ToString();
            labelToPrint += "P1\n";

           // Send a printer-specific to the printer.
            RawPrinterHelper.SendStringToPrinter("zebra", labelToPrint);

This ends up sending this string to the printer:

I8,A,001

Q204,024
q448
rN
S4
D7
ZT
JF
O
R21,0
f100

But this results in a QRCode that does not resemble the actual image

Thanks !!
