    What’s this? I’ve never seen yellow dots on stuff I print

    Edit: looked it up, intresting and definitely a bit disturbing from a privacy perspective. Particularly that it was kept secret until 2004.

      theyre microscopic. theyre typically used to track printers doing illegal stuff (e.g counterfeiting) and leak tracking if someone when to scan some document and post it somewhere it shouldnt be. Of course, this is antithetical to privacy. The yellow dots are microscopic throughout the page.
