How can I print one submitted form at a time? I need a hard copy of each form submitted

You need to access your form submissions page, view the specific submission that you'd like to print and click the Print button on the page.

Another method would be to have the submission attach as a PDF in the notification email, so once you receive the submission, you can download the PDF and print it.
