A printhead is provided having corresponding nozzles, chambers and heaters. Each heater has a heater element and electrodes connecting current from a power source to the heater elements to heat, and form gas bubbles in, liquid within the chambers which causes ejection of the liquid from the nozzles. Each heater element has a cross section with a lateral dimension at least triple that of the thickness of that heater element and different than a lateral dimension of each other heater element of the corresponding chamber. The thickness of each heater element is less than 0.3 microns. The heater elements and associated electrodes are arranged so that the electrodes are non-coincident with the electrodes of the other heater elements.
