I have an app with an NRichTextView that loads and displays rtf files fine,  I've added a print button with this code:

txtnotes.Print();

and

txtNotes.Print(new Nevron.Nov.UI.NPrintDialog());

and

Nevron.Nov.UI.NPrintDialog printDialog = new Nevron.Nov.UI.NPrintDialog();
printDialog.EnableCurrentPage = true;
printDialog.NumberOfCopies = 1;
txtNotes.Print(printDialog);
(with and without a printDialog.PrinterName specified)

I've even tried

printDialog.RequestShow();

but whenever I click Print, nothing happens.  I've also checked the NOV Examples App and clicking Print does nothing there too.  Am I missing something or does it not work on OSX or Xamarin?
