Hello Michael!
Thanks for reaching out! Let me try to help you with that.
There is no built in way to achieve what you are looking for, but I did found a code snippet from Cliff that will add some css styles for a more print-friendly version of the month calendar. You can tweak it to suit your needs.
Try placing the following snippet into your theme’s functions.php file:

If you want to add a print button, you can do so by customizing the month templates using one of the methods described in our themer’s guide > https://theeventscalendar.com/knowledgebase/themers-guide/
Additionally, I found an article out there that explains how to add a print button > https://www.thoughtco.com/how-to-add-a-print-button-4072006
I hope that helps! Let me know if you have any follow up questions and I’d be happy to help.
Best,
Victor
