I wouldn't have given it a try EXCEPT I got the new Chrome Notebook and wondered how I would print from it when the time came.
The instructions built into the notebook spoke about it, but I decided to give it a shot- sweet moses, I am about sold.
It was super simple. Go to the computer connected to the printer. Log into your Chrome and go "under the hood." You will scroll to the bottom and find the Cloud print. It will recognize ANY printers connected to the computer and wham you are set!
I logged back into my notebook and was able to print. Took about 3 minutes total.
I understand this will work for mobile including tablets!
