Last year Google announced Google Cloud Print on PC based browsers and last month opening it up to the Chrome Notebook users. Today they announced that they were going to start rolling out in the next few days Cloud Print for Mobile Documents and Gmail. This will allow users to print from within their smartphone to a printer that must be set up in advance on a Windows PC. (Linux and Mac users will have to wait)
In the iOS version of Google Cloud Print, all you have to do is use the drop down box and select print or look for the “Print” option next to the attachment on certain files types. For now, Google Cloud Print only supports HTML5, such as devices running Android 2.1+ and iOS 3+.
