Google and printing threads

Ok sometimes when there are no new post to check I will check to see what members/google is doing.. And lots of times I will look over at it and see google is printing threads. I have seen this lots of times.. Do you really think google is printing the threads or do you think there just on the printing page.. I know there just bots but who knows they might be printing the page what do you think?

No i dont think they are printing the page
They are just on printing page

But wouldn't be so funny if they really were printing the thread? I bet there printer would be running 24/7.
