What personal info is printed in these yellow dots? Are they present if I print from Linux? Brother colour laser owner here.
Edit, from [1] posted in this thread it looks like date printed and printer serial number are printed. And if it's done by the printer firmware it wouldnt help to use OS drivers.

Not sure but I'd expect it's handled at the printer firmware level and not controllable from the OS. It would be pretty weird to let the user modify such a "feature" without even having to disassemble their printer.
You could add decoy dots or areas of negative yellow
