It would be a shame if the printer left an identifiable mark on the page that allowed for the printer to be identified. https://computer-hardware.wonderhowto.com/how-to/view-your-printers-secret-dots-fingerprints-271717/
It's not a matter of black and white, but ink jet vs laser. If you have a color laser printer and print a black and white file it can still leave the yellow dots. As I understand it, most ink jet printers don't do fingerprinting. Monochromatic laser printers are incapable of leaving the yellow dots.
