If you are getting a message in CalPrint about calendar access or you can't see any events, then you need to check your device access settings.

If your calendar is not displaying in CalPrint, tap on the app settings cog button inside of CalPrint. Open the Calendar section - Calendars. Make sure your calendars are selected.

Also open the Apple iPad/iPhone "Settings" app > Privacy > Calendars > CalPrint. Check that CalPrint is set to "on".

Also tap into the Settings app > Scroll near the bottom and click on our CalPrint. Turn on "Calendars".
