The development of this functionality has started on 20th august 2015 as it is written in the Customer Feedback :
I think that it will be available in a few month.
I hope I answered your question.
Thanks for your answer. Would you please send me a notice when it is ready. Many of my colleagues need this functionality.
The print button is going to be available really soon for On-Prem and O365. It has been requested for a really long time. You should keep an eye on the release notes for the few next versions!
