The current business model for printer manufacturers is to sell printers at a loss to try and lock a consumer into a specific ink, and then make money on ink, which is crazy expensive. This leads to all sorts of ridiculous stuff like lawsuits on third-party ink manufacturers, date stamps on ink tanks, computer chips on ink cartriges to amke you buy more before you even use it all, etc.
If someone made a printer that was honestly built to just work well, and they opened the specifications to the ink formula and the ink tanks in order to ensure that the ink would always be cheaply available, and charged a real cost of manufacture + mild profit margin. Would they make any money? The market seems to indicate that the answer is no, if you assign any intelligence to the "ink as a revenue stream" business model. However, I have to say that I would be very tempted to spend twice as much or more on a printer from a company that honestly said "Hey, here's how much the thing really cots, and we won't rape you on ink."
