If you are getting a message in Print 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 Print, tap on the app settings cog button inside of Print. Open the Calendar section - Calendars. Make sure your calendars are selected.

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

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