Can the customer print out their form after they've filled it out?

Yes, you can put a "PDF Link" in the Thank You page or in the Autoresponder Email. Here's how:

In Form Builder V4, click the "Settings" menu and then go to the "Thank You Page" section. In the Thank You Page Editor, click the "Form Fields" drop down and select the "PDF Link" option. This will generate a string {pdf-link}.

In the Autoresponder email, you can attach a PDF submission. Go to the "Emails" section and select the Autoresponder. Go to the "Advanced" tab and enable the "PDF Attachment" option.

After the user downloaded the PDF file, they can just print it.

Hope that helps. Thank you.

I tried the first way (putting a PDF LINK in the Thank You page).  This made the form not pop up

 when the cient clicked the link to fill out the form.

I cloned this form (https://www.jotform.com/70127488825160) and I can see that you haven't added the PDF link in the Thank You page.

Please share the the URL of the webpage where the form is embedded so that we can further check.

We'll wait for your reply. Thank you.
