/// <summary>
/// Print label using Command line

public void BarTenderCommandLinePrintLabel(string btwFilePath)
{
Process p = new Process();
p.StartInfo.FileName = bartenderPath;//bartender.exe path
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.UseShellExecute = false;

//p.StartInfo.Arguments = " /F=" + '"' + btwFilePath + '"' + " /D=" + '"' + dataFilePath + '"' + " /P/X";
//./P  Executes a print job, leaving the status of the Use Database check box of the Print dialog unchanged
//./F  Specifies a label format to load.
//./D="<path to data file>"
//./X  Specifies that, after all requested functions have been performed, BarTender will automatically exit,
//     but without saving any changes that may have occurred as a result of any command line actions
//     that were performed or data values that were incremented.

p.Start();
p.WaitForExit(30000);
p.StandardOutput.Close();
p.Close();
p.Dispose();
Thread.Sleep(1000);
