Great question Dain! This feature is currently under construction, and should be available in the near future! We will make sure that you're added to the feedback request for this so you are notified of it's release, and let you know here on this post.

While you're waiting on this feature, a workaround is to export your calendar to a spreadsheet to print. Many users are doing this while we build the print functionality. Click Here for a guide to exporting your calendar, which creates a spreadsheet you can then print. 

Thanks for your post! Post again to let us and other users know if there are any other items we can assist with
