Wow I just found out that color printers add coded dots onto every page you print so that it can be traced back to where and when it was printed. Umm.... did anyone else know about this https://en.wikipedia.org/wiki/Machine_Identification_Code

A Fediverse instance for people interested in cooperative and collective projects.
