According to the documentation, I need a print module in order to be able to print the event calendar. It says “This needs to be added to the download package or installed separately from a dedicated NPM package.”
But how do I add it to the download package? I don’t see any option for it on this page: https://download.mobiscroll.com/#/eventcalendar/jquery/ios/material/windows/uf76214/l-en
Hello @Vincent_Wansink 
The Print module is only available as an add-on for your current license.
As I see, you didn’t purchase it so, that’s the reason why you are not able to download it.
If you need the Print module, you can purchase it from your Account–>Licenses–>Addons–>Add the print module.
Thank you. Just a suggestion, it might be good to add a link to these add-ons in the documentation.

And also from the download page. At least to let me know these add-ons exist, and give me an easy way to find them and purchase them, cause I had no idea.
