Let's say you need to print an important email attachment on your way to work so that it's waiting for you when you walk in the door. With Gmail for mobile and Google Cloud Print — a service that allows printing from any app on any device, OS or browser without the need to install drivers — you can.
To get started, you'll first need to connect your printer to Google Cloud Print. For now, this step requires a Windows PC but Linux and Mac support are coming soon. Once you're set up, just go to gmail.com from your iPhone or Android browser and choose "Print" from the dropdown menu in the top right corner. You can also print eligible email attachments (such as .pdf or .doc) by clicking the "Print" link that appears next to them.
We're rolling this feature out in U.S. English over the next few days, so if you don't see it right away please check back. In the meantime, you can learn more in the Google Cloud Print help center.
