I think every release of Outlook had at least one printing bug slip though the beta testing phase because so few people print calendars and Outlook 2013 kept up the tradition. This time around, the bug is with the Calendar details style: Appointments are duplicated in the print out.
Microsoft is aware of the problem and is investigating. At this time, the only workaround is to use a different format, as the Calendar Printing Assistant for Outlook does not work with Outlook 2013.
