If you switch to or sync with Google calendar, you can print from the web version of the Google calendar. By printing, I mean you can also print/save to PDF. Why do you need to save/export a calendar? Because it's electronic, it lives in history. Google Calendar has the added advantage of being accessible anywhere, on any device. If you really love Samsung Calendar, you can still do your calendar entries in that app, all your events will appear on both calendars, regardless of which one you add them to. You don't even have to download Google Calendar to your phone if you don't want to, it will still sync with Samsung Calendar.
