My printer was printing a line every two minutes, someone suggested shaking the cartridges and it worked back to fast printing, HP Deskjet D1460, so when ink is low shake the cartridges.
We do that at work, we have HP lasers, useless heap of junk they are, not sure of the model numbers, but we have two different types and i know they get a lot of use but they go wrong so often.
We had a new brother all in one laser about 3 months back, a different kettle of fish, it is quiet, reliable at the moment and the print quality is so much better than the Hp.
but yeah the shaking of the cartridge seems to work when they are getting low
