Yeah I badly want revenge on the whole industry, or at least a way of banishing them from my life forever, but the local maximum I've attained thus far is to buy bottles of ink, drill small holes in the top of the cartridges, inject ink and cover the holes. The printer still complains of low ink (i.e. it's lying and probably always was), but you can suppress the warning. So it costs me one sheet of paper to find out the truth about my ink levels, and I haven't bought a cartridge in years. I have two color & two black, so I can swap a full one in and refill the empty one at my convenience.
