Barcode printing Sato Lm 408e thermal SBPL

Question

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("<STX><ESC>A");         

sb.AppendLine("<ESC>H0001<ESC>V0001<ESC>XM45676567");         

sb.AppendLine("<ESC>Q1");         

sb.AppendLine("<ESC>Z<ETX>"); 

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

output.Replace("<STX>",((char)2).ToString());         

output.Replace("<ETX>", ((char)3).ToString()); 

if (result == DialogResult.OK)      

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