Well. Google has done it again. The “Cloud Print” feature they are developing for the Chrome OS, has migrated out to The Mobile Web Versions of Gmail and Google Docs for Android 2.1+, iOS 3.0+ and while not officially listed, it works great on WebOS 1.4.5 (tested it myself) You can print attachments as well as emails and Google Docs. Note that the attached PC is still required to be on, and you cannot yet share printers from one account to another, but that is all in the works…
I could see all kinds of great ministry use for this…
