Hi there, @user16904 
We’ve got 2 custom solutions that let you hide or blur results until the form completion:
- Calculator: How to hide results until the form is submitted
- Calculator: How to blur results until the form is submitted
Would it work for you if the Print and Download button will also be hidden until the form completetion instead of triggering the form on the Print/Download button click?
Also could you please share a name of your Calculator widget, where you’d like to implement this customization?
