Not a whole lot on this at the moment, on the google site [HERE], however definitely something to be watchful for. It is Google Cloud Print.
By connecting your printer with the Google Cloud you will be able to print to your printer from any computer or smart phone, regardless of where you are. Just activate the Google Cloud Print connector in Google Chrome and your printer will automatically be available to you from Google Cloud Print enabled web and mobile apps.
Appears this cloud app is currently in beta and can be tried and tested, if you desire, by downloading Chrome from the link indicated above. If you are currently running Chrome on your main PC, I would wait until it comes to you via the Chrome Updates. I am currently running the development versions of Chrome and I am not seeing this option in my browser, as of yet.
