Have the completed form save as a PDF that can be emailed or saved.
You can print to PDF in FORMS but it must be done manually and individually. Google forms sends the PDF form response which can then be saved, which is significantly more efficient than FORMS.
Yes, please allow Forms to create a PDF of the completed form with questions and answers. Google Forms allows you to select "email a PDF copy," and the participant receives a copy of their questions and answers as a PDF in their inbox.
Our organization could utilize Microsoft Forms if they had this function; right now we're stuck in Google Forms due to this feature.
