This feature will be rolling out today and tomorrow for English speaking users in the US and will work on most phones that support HTML5, such as devices running Android 2.1+ and iOS 3+. To get started, you’ll need to
connect your printer to Google Cloud Print. This step requires a Windows PC for now, but Linux and Mac support are coming soon. You can learn more at the
Google Cloud Print help center.
