The brother printer my spouse has had for ages is finally running out of ink and a quick chedk shows that they don’t make cartridges for it anymore, you cant reset them, and you can only buy dubious 3rd party options on amazon for $150 each. For that kind of money id rathet find a printer that let’s me put of the scam, but im not finding a lot of options there. Does anyone have advice?

That must be a model-specific enshitification. If the tanks are refillable (as @orbituary@lemmy.dbzer0.com says), then why would it matter?
I have not used an ecotank, but my local dollar store type of place sells a full set of generic ecotanks (45ml per tank) for less than a Big Mac. So it seems the Ecotanks avoid the shenannigans.
The Ecotanks are efficient and in two years, I’ve filled mine exactly once… That was last week.
