Google Cloud Print is a service that enables any application (web, desktop, or mobile) on any device to print to any printer. The service is still under development, but we are making code and documentation public as part of the open-source Chromium and Chromium OS projects. We want to be as transparent as possible about all aspects of this design and identify the right set of open standards to make cloud-based printing ubiquitous. You can view our design docs and outlines here and we hope you stay tuned for updates.”]
