Google has expanded its Google Cloud Print to work on mobile documents and Gmail for mobile. ­Last April, Google had launched a service that enables users to print documents from any device without having to install a dedicated printer driver in the computer.

To send a document to a printer, the user just need to open a document in Google Docs or an email in Gmail in their mobile browser and chooses “Print” from the dropdown menu in the top right corner. Users can also print certain kinds of email attachments (such as .pdf or .doc) by clicking the “Print” link that appears next to them.

This feature will be launching for English speaking users in the USA and will work on most phones that support HTML5, such as devices running Android 2.1+ and iOS 3+.

To get started, users will need to initially connect their printer to Google Cloud Print, which requires a Windows PC for the initial step. Thereafter, everything can work through the mobile phone.
