They sell printers at a loss and make the money back on ink sales. You can get printers with refillable ink tanks from all (three) major manufacturers, but they cost significantly more because they aren't subsidized by ink sales
And you have to search for them online or order from various strange places because no major stores where people actually go buy "computer stuff" carry them. Coincidence? I think not.
Worse, even the lot more expensive "office" printers (both laser and inkjets) have been sabotaged by such "driver update for your own good" shenanigans in the past. This isn't limited only to the cheapest disposable inkjet junkers.
