EFF seems to think that all modern laser printers have some form of tracking dots, whether or not they've actually been able to detect them [1].

They don't say anything about inkjet, though. Unclear if this is because of a fundamental limitation of inkjet printers, lack of interest, or just because inkjet printers kind of suck compared to laser. :P
