First of all, if you want to use a CPrintDialog object, you should create the object using the CPrintDialog constructor. You could set or modify any values in the m_pd structure to initialize the values of the dialog box's controls. After initializing the dialog box controls, you could call the DoModal member function to display the dialog box and allow the user to select print options.

Whether you have used CPrintDialog::m_pd to initialize the value of the dialog box control before calling the DoModal function?

For more details, I suggest you could refer to the Doc: https://learn.microsoft.com/en-us/cpp/mfc/reference/cprintdialog-class?view=msvc-160#remarks
