{
   try
   {
       PrintDocument fpd = new PrintDocument();

       string filePath = fileName;
       string printer = fpd.PrinterSettings.PrinterName; //获取默认的打印机
       ProcessStartInfo info = new ProcessStartInfo();
       info.Arguments = "\"" + printer + "\"";
       info.Verb = "PrintTo";
       info.FileName = filePath;
       info.CreateNoWindow = true;
       info.WindowStyle = ProcessWindowStyle.Hidden;

       Process p = new Process();
       p.StartInfo = info;
       p.Start();
       p.WaitForInputIdle();
   }
   catch (Exception ex)
