Someone mentioned something about in the US, this would be illegal due to DRM laws - not sure about the specifics of this, but regardless an open source printer seems like something we’ve needed for ages, as printers are something that always seem like way more of a headache then they need to be.

The cartridge is refillable
It’s been a while since I looked at it, but if I remember they specifically choose a pretty old model that is widely cloned.
