You may obtain a wxPrinterDC
device context from
a successfully dismissed print dialog.
Constructor. Pass a parent window, and optionally a pointer to a block of print
data, which will be copied to the print dialog's print data.
Destructor. If wxPrintDialog::GetPrintDC has not been called,
the device context obtained by the dialog (if any) will be deleted.
Returns the device context created by the print dialog, if any.
When this function has been called, the ownership of the device context
is transferred to the application, so it must then be deleted
Shows the dialog, returning wxID_OK if the user pressed OK, and wxID_CANCEL
otherwise. After this function is called, a device context may
be retrievable using wxPrintDialog::GetPrintDC
