People say that, but...
I had a Canon Pixma ip5000 back in the day that had ink cartridges with no electronics in them. For ink level sensing there was an LED and photodiode built into the carriage that the cartridges went into, in the printer itself. Not in the cartridges. They were transparent plastic, so the machine could just shine through and determine when ink was running low. For its usage gauge, it just calculated it based on print output vs. the volume of a new cartridge, assuming you put a full cartridge into it when you told it so. Yes, this meant you could also fool it by telling it you'd installed a new cartridge when you hadn't, but it would still figure it out right away if you put a truly empty one in.
And this worked just fine. No problems at all with that system. I used and abused that printer for years, doing volume printing for work with it (it could do 8.5x11 borderless!) until it just plain wore out. Probably after hundreds of thousands of pages.
So no, I really don't think having chips running arbitrary code in a goddamn ink cartridge is actually necessary in any way.
Crazy idea here: How about not monitoring the ink at all?
Why does the printer need to know? It's not like it's going to explode from not having fresh ink anyway. Just put the ink in a visible container where the user can look and see if it being empty is the cause of a shitty print.
I'd buy any printer that doesn't attempt to monitor the ink.
Actually with some print heads they will be damaged if there is no ink
