Thanks for providing details of your concern, @karen243. I recognize the inconvenience this issue has caused you in completing your task in QuickBooks Online.

Please know that the glitch you're facing is due to the newly installed macOS version you've had or the Sonoma 14.0. We are aware that when using QuickBooks on the new macOS Sonoma, there can be issues when doing tasks like printing issues with your estimates. Intuit is currently working on compatibility patches for all of our supported versions of QuickBooks for Mac. 

That said, I recommend printing your estimates by saving them to your desktop and opening them in Acrobat or Word just like what you did. You can continue doing that in the meantime until the compatibility patch is available.

I've added this article for future use if you need help with common printing issues when using QuickBooks Online on a browser for Windows: Fix QuickBooks Online printing issues on browsers for Windows.

We appreciate your patience as we work to resolve this issue for you. Don't hesitate to come back if you have other questions or concerns. We'd be glad to help.
