Using Java Script to print limited content

Good day! I've been working on a way to print a specific part of one of my slides content while viewing in HTML. I've read a lot, but obviously not enough, web content to kill a brain and they all seem to do the same thing about printing an HTML screen. They use the 'window.print();' javascript line. While it works great for printing the whole screen, but I am trying to print only the text inside the scroll box. (See attached link)https://360.articulate.com/review/content/45a7519f-1409-47dc-a4e0-47d411000642/review  I've incorporated the user data behind the scene with the correct variables and it looks good when you scroll through the data on the screen. Now, I just want to be able to allow the user to print it off.  HELP!
