Google Cloud Print allows you to print on the go

Any phone that supports HTML5 can now use Google Cloud Print and a printer to print out documents and Gmail while on the go. Phones HTML5 enabled should be able to use the application, which hooks up to your Windows PC printer (support for Mac and Linux are coming soon).

Click activate to get the Google Cloud Print connector from Google Chrome and your printer will be available to you from Google Cloud Print enabled web of mobile apps. Once installed, simply navigate to your mobile browser and use the dropdown box on the right to select "print". Gmail users will be happy to know that ".pdf" and ".doc" attachments can also be printed using this application.

On the source link is a button to install a version of the Google Chrome browser that includes an early release of the application which "may have some rough edges". Google Cloud Print has been in beta for about a year before today's rollout
