I just read this article on Mashable:
Google Cloud Print Reveals the Future of Printing
This could eventually be combined with Google maps and location-aware apps. Then, if I am on my mobile device and I need to print a document quickly I can pull up a map and find all the nearest public printers that I could use, such as from Kinko’s, Staples or other office type stores near my current location or my destination.
That would be sweet. I’m on my iPhone, get a document from a client that needs to be signed, I review it on my iPhone and then print the signature page near our meeting. I pick it up, sign it and deliver it on the spot. Cool!
