Select this option if you want AppWizard to generate the code to handle the print, print setup, and print preview commands by calling member functions in the CView class from the MFC library. (Available only for programs with the Doc View architecture.) AppWizard also adds commands for these functions to the program's menu. By default, programs have printing support.
