I've been trying to figure out a solution to a problem related to my day job. (and I did)
The Chrome printing feature is great. With window.print(); you can print whatever is on the page and style it with the print CSS media query.

SaaS Idea
What if you could copy-paste a short script into your website (think Google Analytics) that generates a Print button.
Once you press that Print button a real PDF (not a Screenshot) is generated from whatever content you have in front of you. Basically the Chrome PDF print feature as a server-side service.
I'm just throwing it out there... what do you think?
