Some printers detect when cartridges have been refilled by the user and are programmed to stop working then.

This is absurd. I would like to hear how this benefits the consumer without attempting to talk about “quality” or something. This would be like my car not starting cause I didn’t use Shell gas.

What’s more upsetting is that printers are client side all the way. There is nothing about them that needs to teach or to the Internet to print pages. The printer itself handles the “letting you print.” So the thing sitting on your desk, that you own, is choosing this for you.
