Print Anything on Any Printer from Anywhere
Google Cloud Print was developed in fall 2009, thrown to developers in April 2010, and has been fully functional for some time. In theory it's perfect: print anything from anywhere. As usual, in practice things get trickier. What if you're on the road? Can you print a document at your office by pushing a button on your iPhone? Things like that get sorted out in articles like this one. In the meantime, if you don't already use Cloud Print I recommend giving it a try. Its easy, convenient, and can be a lifesaver.
