C# – How to send control codes to Epson dot matrix printer from Windows

This is technically possible by putting the printer in graphics mode and sending pixel data. You'll have to create a monochrome bitmap in your program, the Bitmap and Graphics classes can get the job done. You'd use Graphics.DrawText with a Font initialized with Arial to get the text the way you want it. Encoding the bitmap pixels into printer commands is the non-trivial part, be sure to have a decent programming manual for the printer.

This is otherwise exactly what the printer driver does. It will be just as slow.

Thank you very much Hans. Now I can send Paper cut command by using Microsoft RawPrinterHelper class. I've been seeking this solution for six days. Here is what I've done.

string GS = Convert.ToString((char)29);
string ESC = Convert.ToString((char)27);

string COMMAND = "";
COMMAND = ESC + "@";
COMMAND += GS + "V" + (char)1;

PrintDialog pd = new PrintDialog();
pd.PrinterSettings = new PrinterSettings();
if (DialogResult.OK == pd.ShowDialog(this))
{
RawPrinterHelper.SendStringToPrinter(pd.PrinterSettings.PrinterName,  COMMAND);
}
