Thank you for joining the Community. I'd be happy to help get this taken care of today.
May I know the exact error message you get when trying to print or send the estimate? It can help me check if there's a reported issue related to your concern today.
In the meantime, let's try to perform some troubleshooting steps that can help isolate this. It's possible that this is a browser issue, which we can test for by trying to print and send the estimate in a private browser.
These steps will vary based on which browser you're using.
