Hi ​@AnthonyKumnick 

thank you for posting and asking the question. We have seen an idea for this come up in the past, which you can view here: The ability to print / export to PDF Checklists | Nintex Ideas

There has not been much traction for this but please do vote the feature improvement and we will track on our side and see if interest for this grows as we start looking at new improvements. 

Hi ​@AnthonyKumnick - as a workaround to printing, I use an extension on the browser called GoFullPage that prints the entire browser window.  Once the browser has been captured, you then have the option to save in PDF/image format.
