You can prevent the details of private appointments from appearing on printouts of your Outlook calendars.
To avoid printing private information, you must ensure that your private calendar items have been marked as private. To mark appointments and meetings as private, see Make an appointment or meeting private.
Items marked private appear with the description Private Appointment, but do show the subject, location, meeting organizer, or other details except for the start and end times. There is no option to print the calendar without the appointment or meeting appearing.
On the File menu, click Print.
Keyboard shortcut To print, press CTRL+P.
Under Printer, click Print Options.
In the Print dialog box, under Print Range, select the Hide details of private appointments check box.
Select any additional printing preferences.
