Epson printers do not measure actual ink. They only go by counting the
number of shots of ink, and cleaning cycles performed. Usually they
are rather conservative and may still have 1/3 of the ink left, in
fact there is a class-action suit over that.

Canon printers us an optical system to determine when the ink is
actually low.
