Secret Printer ID Codes May Be Illegal In the EU
I Don't Believe in Imaginary Property writes "In response to a query from a member of the EU Parliament, an EU commissioner issued an official statement (.DOC) saying that, while they do not violate any laws, secret printer tracking dot codes may violate the human right to privacy guaranteed by the EU's Convention of Human Rights and Fundamental Freedoms. If you don't remember what these are, Slashdot has discussed the issue before. In short, most color printers print small yellow dots on every sheet in a code that identifies the printer and, potentially, its owner. The EFF is running an awareness campaign, and a couple of years back made a start on deciphering the yellow dot code."
No, it's definetly a hardware level process, you get them even with internal printer status/info pages (assuming they are color).
On the bright side, most color lasers do not insert the yellow dots on black and white pages, though a few models from various manufactures DO tag every single page.
This signature is lame.
