PRINTDLG& m_pd;
Remarks
A structure whose members store the characteristics of the dialog object. After constructing a CPrintDialog object, you can use m_pd to set various aspects of the dialog box before calling the DoModal member function. For more information on the m_pd structure, see PRINTDLG in the Win32 SDK documentation.
If you modify the m_pd data member directly, you will override any default behavior.
