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.
\snippet doc/src/snippets/code/src_gui_dialogs_qabstractprintdialog.cpp 0
If the dialog is accepted by the user, the QPrinter object is
correctly configured for printing.

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.
The native print dialog on
Mac OS X does not support setting printer options, i.e.
QAbstractPrintDialog::setEnabledOptions() and
QAbstractPrintDialog::addEnabledOption() have no effect.
In Qt 4.4, it was possible to use the static functions to show a sheet on
Mac OS X. This is no longer supported in Qt 4.5. If you want this
functionality, use QPrintDialog::open().
