Well, won't take long to track these jackholes. Each printer has a unique fingerprint, with each page receiving a unique time-stamp. Match that up to any account that was logged into the computer that printed the document, and you have your guy.

Oops.

From WikiPedia:

Printer steganography is a type of steganography – "hiding data within data"[1] where tiny yellow dots are added to each page. The dots are barely visible and contain encoded printer serial numbers and timestamps. Unlike many forms of steganography, the hidden information is not intended to be available from a computer file, but to allow serial number and time of printing to be determined by close examination of a printout.
