How do I send a Line Model control command to a Zebra printer?

Question

I have the following code, which I send after putting the printer in line mode, but it just prints the '51' after swallowing the [ESC]A

The command to change font is [ESC]A51

var hexValue = "1B"; // ESC char in HEX
var asciiValue = System.Convert.ToChar(System.Convert.ToUInt32(hexValue, 16));
var stringVal = new string(new char[] { asciiValue });
stringVal = stringVal + "A51"; // Smaller Font

data = Encoding.Default.GetBytes(stringVal + NewLine);

connection.Write(data);

What type of object is `connection`? – Lynn Crumbling Oct 07 '14 at 13:42 — Lynn Crumbling, Oct 07 '14 at 13:42
the `hexValue` is not correct write `hexValue = 0x1b;`? – Jones Jan 06 '15 at 09:44 — Jones, Jan 06 '15 at 09:44

Need some correct codes to normalize the output to printer.

var stringVal = new string(new char[] { System.Convert.ToChar(0x1b) /* ESC */, 
                                        'A', 
                                        System.Convert.ToChar(51) });
data = Encoding.Default.GetBytes(stringVal + NewLine);

connection.Write(data);

EDIT

In this case A51 need attention. If 51 is string, using '5', '1', or a char, using System.Convert.ToChar(51), the command is different way to pass.
