    ^GFa,b,c,d,data command, how calculate the parameters?

      Hi.

       

      I have .PNG file, which has 800x800 px size (it is monochrome). I want to print it.

       

      I use:

       

      string ConvertToHex(string inputFilePath)
      {
           var bytes = File.ReadAllBytes(inputFilePath);
           var hexString = string.Join("", bytes.Select(x => x.ToString("X2")));
           return hexString;
      }
      
      //...
      string hexBytes = ConvertToHex(@"TEST.png");
      int length = binaryData.Length;
      int length = binaryData.Length;
      int inRow = length / 16;
      string str = "^XA^FO0,0^GFA," + length + "," + length + "," + inRow + "," + hexBytes + "^XZ";
      

       

      but when I send it, it doesn't print corectly, it prints one cm of different pixels.

       

      How to calculate length of image and inRow bytes?

       

      Thanks Mike
