  \class QPrintDialog qprintdialog.h

  \brief The QPrintDialog class provides a dialog for specifying
  the printer's configuration.

  \internal

  \warning The use of this class is not recommended since it is not
  present on all platforms; use QPrinter::setup() instead.

  \omit

  (ingroup dialogs)

  THIS DOCUMENTATION IS Not Revised. It must be revised before
  becoming public API.

  It encompasses both the sort of details needed for doing a simple
  print-out and some print configuration setup.

  The easiest way to use the class is through the static
  function getPrinterSetup().  You can also subclass the QPrintDialog
  and add some custom buttons with addButton() to extend the
  functionality of the print dialog.
