Not heard of this technology in black and white printers but that does not mean it does not exist in a different guise, yellow dots can be camouflaged in a colour document but would stand out in a black and white document so an alternative method quite possibly does exist and is used, some info on such printers here
Tracing a document back to a printer is one thing but determining who actually printed the document is another matter + keep in mind that unless a printer has been registered with the manufacturer for warranty purposes etc it may not be known who actually owns the printer that produced the said document.
NB: The technology is used for catching bad guys btw and the majority of people need not have any concerns about it
