Hi @Iniobong Nkanga ,
Thank you for posting in this community.
Since we can't reproduce your situation, we need to narrow down the problem and try some things.
- If the same issue happens on multiple calendars from different sites?
- If the same issue happens on various browsers?
- If other users will see a same behavior when they try to print?
As a temporary workaround, you can connect the SharePoint calendar to Outlook (click the CALENDAR tab> Connect to Outlook), and then print the calendar.
We were unable to determine if the problem was caused by the update. We suggest you can create a new service request in M365 admin center as an admin, They have higher authority. And more professional will help you.
(Microsoft 365 admin center ->> Support ->> Help & support)
