How to Let Users Be Able to Print their Submission?

quiero que la gente que conteste el formulario pueda imprimirlo, como hago?

Hi Alexandro,

Thanks for reaching out to Jotform Support. Unfortunately, our Spanish Support agents are busy helping other Jotform users at the moment. I'll try to help you in English using Google Translate, but you can reply in whichever language you feel comfortable using. Or, if you'd rather have support in Spanish, let us know and we can have them do that. But, keep in mind that you'd have to wait until they're available again.

Now, let me help you with your question. You may include an action button on the thank you page so that your users can download and print the PDF. Let me show you how:

1. In Form Builder, scroll down to the bottom of the form, hover your cursor in the lowest portion of the form's last page, and click on Edit Thank You Page. 
2. Click the Action Buttons and select Download PDF.

You can also attach the PDF to their email by enabling the Attach PDF option in your Autoresponder. This guide will show you how to do that.

Give it a try and let us know if you have any other questions.
