Google Calendar, like most products in Google Workspace, has lots of little features that are often overlooked. Just because those features are overlooked doesn’t mean that they’re not useful. For example, you can print a guest list from an event on any of your Google Calendars. In the short video that is embedded below I demonstrate
how to print guest lists for Google Calendar events. 

I use printed guest lists for meetings because it’s often faster for me to take attendance on paper than it is to toggle between tabs or screens (especially when hosting virtual meetings).
