ASCII CODE for Dot Matrix Printer for changing Ribbon in C# using Raw Printing

Question

I am printing receipts using Dot Matrix Printer in C#.

The printer works perfectly, prints characters in bold, large size etc.

The problem is dot matrix have ribbons in it (Black color, Red Color)

How can i specify which text is to be printed in black or red.

I am using BinaryWriter to pass string and ascii code to get desired output.

Example:

 bw.Write((byte)0);

 byte[] bytes = Encoding.ASCII.GetBytes(text);

 foreach (var by in bytes)
 {
    bw.Write((byte)by);

 }
