今天无意中退出gmail,返回gmail首页,看到其一项举动:打印你的邮件.Google负责相关的所有费用,他会在打印出的邮件背面印上广告,呵呵.不过我没有在我的gmail中看到这个按钮,可能是google判断我是Chinese吧.

详细可以看看Google的说明:
Is it free?
Yes. The cost of postage is offset with the help of relevant, targeted, unobtrusive advertisements, which will appear on the back of your Gmail Paper prints in red, bold, 36 pt Helvetica. No pop-ups, no flashy animations—these are physically impossible in the paper medium.
How about attachments?
All part of the deal. Photo attachments are printed on high-quality, glossy photo paper, and secured to your Gmail Paper with a paper clip. MP3 and WAV files will not be printed. We recommend maintaining copies of your non-paper Gmail in these cases.
Is there a limit?
You can make us print one, one thousand, or one hundred thousand of your emails. It’s whatever seems reasonable to you.
But what about the environment?
Not a problem. Gmail Paper is made out of 96% post-consumer organic soybean sputum, and thus, actually helps the environment. For every Gmail Paper we produce, the environment gets incrementally healthier.
4.1是什么节?
是不是还没反应过来?
Google adwords现在推出了一个真实的类似业务,google print ads,呵呵,也算是这个节目的扩展吧.不过现在还仅限US用户使用
