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.
