You could just do ctrl + print screen and then paste and save the images using any imaging utility, such as
Irfanview. It might take several screens' worth, but it's the quickest way I can immediately think of.
Just press ctrl and print screen (top right on yr keyboard, above the numbers keypad), then open Irfanview, and click Edit, Paste, or ctrl+V. Save that image, scroll down on the web page and repeat as reqd.
