FFS, How much do we trust Google
Cloud applications, cloud storage and now cloud printing.
Just hope "Do No Evil" never changes. I would hate for a serious commercially sensitive or security document to be snooped while it is passing through the Google print servers because someone knows no better about how their computer talks to their printer. Such information could be worth very large amounts of money.
An just think if a glitch ends up sending it to someone else's printer entirely!
