List of Printers Which Do or Do Not Display Tracking Dots

It would be neat if there was a privacy printing app that added random yellow dots to a document to obscure the info.

Perhaps simply printing a single yellow dot through a few different printers would be enough to accomplish the same thing. Then using the resulting paper for "real" prints.

The more I think about it, this could even be a service. "Preprinted" paper that went though a bunch of printers, each adding their own unique identifier each time, then sold and distributed.

That or just paying cash for a printer.

I hate to be the security is not important if you aren't doing anything wrong guy.... but I use a printer to do things like print a picture for my kid to color. What the hack are you doing with you printer to need pre dotted paper?
