What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
Could you please elaborate? Were you looking for a way to have a completed form simultaneously printed and submitted or did you just want to include a button to print the completed form?
In the latter case, clicking the submit button while in the form builder will reveal a tab containing buttons to change some of its properties. One of them is labelled Print Button:
If you click it a button to print the form will appear on the same line as the submit button.
To have the completed form automatically printed when it's submitted would require custom coding. Please see this thread.
