Printers that don't use toner level chips?

Though they are not using Lexmark printers, I am pretty sure they are using a printer and cartridge combination that uses so-called toner level chips. These are discussed in http://en.wikipedia.org/wiki/Lexmark_Int'l_v._Stat ic_Control_Components. The chips allow manufacturers to lock users into using their cartridges, rather than using OEM or toner refill programs. Good for the manufacturer, bad for consumers and consumer choice. In my bumbling way I've tried locating more information, or even a list, of personal or small workgroup printers that use these manufacturer lock-in techniques, but wasn't able to find such a list. Any Slashdot readers have anecdotal suggestions or even a pretty-darn-sure list I could refer to?"
