Which 2007 Google prank offered to print Gmail messages and mail them?

The 2007 Google prank that offered to print and mail Gmail messages was Gmail Paper.

Google presented Gmail Paper as a fictional add-on to its webmail service. Users were supposedly able to place messages in a “Paper Archive,” after which Google would print them and send them through traditional mail. The mock service even promised glossy paper for image attachments and colorful advertising on the reverse side to cover the cost.

The joke played on the contrast between Gmail’s digital identity and an old-fashioned physical archive. Google claimed that the service was free and used environmentally themed language, including a deliberately absurd description of the paper. Audio attachments were not supposedly printed, adding another layer of mock product detail.

Gmail Paper was not a real Google service and should not be confused with Gmail’s ordinary printing function, which lets users print messages themselves. It was one of several Gmail-themed April Fools concepts, alongside later jokes such as Gmail Motion and Shelfie.
