WPF: How do you print in landscape mode?

found this feature on the internet that works fine ... except that I can't figure out how it prints in landscape orientation by default.

private void PrintClick(object sender, RoutedEventArgs e)
{
  PrintDialog dialog = new PrintDialog();
  if (dialog.ShowDialog() == true)
  { dialog.PrintVisual(_PrintCanvas, "My Canvas"); }
}

How to really set a default value for printing my wpf content in landscape mode?

    { 
==>     printDialog.PrintTicket.PageOrientation = PageOrientation.Landscape;
        dialog.PrintVisual(_PrintCanvas, "My Canvas"); 
    }
}

Edit:

It looks like there is a problem with PrintTicket and print rendering, check: The same question on MSDN

private void PrintClick(object sender, RoutedEventArgs e)
{
   PrintDialog dialog = new PrintDialog();
   if (dialog.ShowDialog() == true)
      { 
         dialog.PrintTicket.PageOrientation=System.Printing.PageOrientation.Landscape;
         dialog.PrintVisual(this, "First LandScape"); 
      }
 }

You need to add a link to ReachFramework.dll and System.Printing.dll each.
