Inkjet cartridges are only refillable a handful of times before components wear out if you don’t screw up the refill in the first place. I used to work at an ink refill franchise, it’s all trash.
A decent toner printer and a small business that will refill toner for cheap is the way to go.
Everyone else in the real world is human, everything else in the fantasy world is muppets.
Except Tim Curry.
