Question

found this function online, which works great… except I can’t figure out how to default it to print in landscape.

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

How does one actually set the default to print my wpf content to landscape mode?

Edit: Fixed variable name, mentioned by @SHIN JaeGuk

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