Hi Giuliano,
Thanks for checking out our plugins! I’m sorry for the delay, we’ve had a high volume of threads in the forums this week.
Printing and favoriting events are not currently features of Events Calendar Pro. For printing, you might be able to integrate with a third-party plugin to get a more printer-friendly version of some of the events pages. You may be able to find a third-party plugin that would allow you to favorite events (which are the tribe_events custom post type) as well.
If these are features that you would like to see added in the future, please do let us know over in our Feature Ideas Forum! This is what we use to gauge user interest in new features and help guide future development efforts.
Let me know if you have any other questions!
