    This class implements getter and setter functions that are used to
    customize settings shown in print dialogs, but it is not used directly.
    Use QPrintDialog to display a print dialog in your application.

    \class QPrintDialog

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

    \ingroup dialogs

    The dialog allows users to change document-related settings, such
    as the paper size and orientation, type of print (color or
    grayscale), range of pages, and number of copies to print.

    Controls are also provided to enable users to choose from the
    printers available, including any configured network printers.

    Typically, QPrintDialog objects are constructed with a QPrinter
    object, and executed using the exec() function.

    \code
        QPrintDialog printDialog(printer, parent);
        if (printDialog.exec() == QDialog::Accepted) {
            // print ...
        }
    \endcode

    If the dialog is accepted by the user, the QPrinter object is
    correctly configured for printing.

    </table>
    \endraw

    The printer dialog (shown above in Plastique style) enables access to common
    printing properties. On X11 platforms that use the CUPS printing system, the
    settings for each available printer can be modified via the dialog's
    \gui{Properties} push button.

    On Windows and Mac OS X, the native print dialog is used, which
    means that some QWidget and QDialog properties set on the dialog
    won't be respected. In addition, the native print dialog on Mac OS X does
    not support setting printer options, i.e. QAbstractPrintDialog::setEnabledOptions()
    and QAbstractPrintDialog::addEnabledOption() have no effect.
