How to export Google Forms responses to PDF

Why a how-to for printing another product's responses is not reproduced here, and how this product turns a submission into a PDF.

The page this one stands in for explains three manual ways to get a PDF out of a Google Forms response, then presents a form builder that does it in one step.

Tinyform does not write guides for other products, so that walkthrough has no counterpart here. The feature it leads up to does exist: a submission can be turned into a PDF, and an email notification can carry one as an attachment. /help/create-a-pdf-from-form-responses describes both, and /help/email-notifications covers the notification side.
