Google is launching a great printing service for mobile documents and Gmail that will allow users to print directly from their mobile devices. You just need to connect your printer to Google Cloud Print, now only on Windows PC (this function will be available for Linux and Mac soon), and send your all needed Google Docs or emails in Gmail to print by pressing “Print” from the dropdown menu in the top right corner.
This great printing opportunity will be available for mobile users from today and will work on most devices running Android 2.1 or higher.
