Print Almost Anything with the Cloud Print Beta App
"Android/Chrome (Windows): Google's Cloud Print setup is a little rough around the edges right now, but the possibilities are looking nice. An Android app, for example, uses Dropbox and Cloud Print to fling almost anything you see or open on your Android over to your (Windows-connected) printer."
I already had Google Cloud Print setup with my home PC, Chrome, and a HP Photosmart 6100C. I installed this "Cloud Print Beta" app and, after approving the Cloud Print permission and refreshing the list, it came up with my printer. It no longer requires that you use Dropbox, as my source mentions, but that's still an option. It looks like they've also increased what you can print and there is a list of things that are apparently coming soon including Mail, Facebook, and Picasa. You can use "sharing" from any app that supports that to try printing but your results may vary. If you have any need to print from Android you should definitely check this out! Let us know what you try printing and what the results are.
