I know this has been around a while, but I have not seen it brought up in this forum. I found you can print directly to a printer with this. After you have enabled your printer on Google Cloud Print (or HP ePrint), you can print directly to the printer when you click the Send or Share button in the App. Just select the Cloud Print option. I have been able to print emails (I use K9), office docs from DocsToGo and QuickOffice, webpages, and pictures from Gallery.
I was always thought this was the biggest deficiency in Android. I just didn't know the capability was already there.
