If you are on a Windows PC, you can download FastStone Capture.
It is a screenshot tool that can automatically take a picture of an entire website, even if you have to scroll down multiple pages. It does that automatically.
I find it works best with IE, and worst with Firefox.
So what I did was I navigated to each page of the application and took a screenshot with this tool and saved it to a folder.
Took about 15 mins.
