They're not going to do it for business-class printers, because businesses aren't going to put up with it. They do it with consumer-class printers because consumers are dumb and want the cheapest thing they can find and don't print a lot, but businesses need printers that can print a lot of pages without maintenance. There's plenty of competition in the business printer market, so it'd be pretty stupid for mfgrs to pull too many shenanigans there.
