Barcode printing Sato Lm 408e thermal SBPL

I'm making an application that produce barcode labels. I'm using Sato LM408e thermal printer. In order to print i'm using sbpl command. I got no error but the printer doesnt print anything. Is there anyone who has experience printing with sato barcode printer? lm 408e to be more specific

My Code:

PrintDialog printDia = new PrintDialog();

printDia.PrinterSettings = new PrinterSettings();

DialogResult result = printDia.ShowDialog();

StringBuilder sb = new StringBuilder();

sb.AppendLine("A");

sb.AppendLine("H0001V0001XM45676567");

sb.AppendLine("Q1");

sb.AppendLine("Z");

String output = sb.ToString().Replace("", ((char)27).ToString());

output.Replace("",((char)2).ToString());

output.Replace("", ((char)3).ToString());

if (result == DialogResult.OK)

  {             RawPrinterHelper.SendStringToPrinter(printDia.PrinterSettings.PrinterName, output);         }
