You can try something like the following below should work for you

public void CustPrinting() 
{
   try 
     {
       strPrint = new StreamReader (filePath);
     try 
       {
         printFont = new Font("Arial", 10);
         PrintDocument pd = new PrintDocument(); 
         pd.PrintPage += new PrintPageEventHandler(pd_PrintPage);
         pd.PrinterSettings.PrinterName = printer;
         // Set the page orientation to landscape.
         pd.DefaultPageSettings.Landscape = true;
         pd.Print();
       } 
     finally 
     {
       strPrint.Close() ;
     }

     MessageBox.Show(ex.Message);
