ABSTRACT:
An inkjet printhead comprises a plurality of nozzles; a supply of printing fluid in fluid communication with the plurality of nozzles; and a plurality of heater elements corresponding respectively to each of the nozzles, the heater elements for heating the printing fluid to form a gas bubble for ejecting a drop of printing fluid of a predetermined volume from the nozzle. Each of the heater elements has an area proportional to the predetermined volume. The area being such that an amount of energy generated by each heater element to form the gas bubble is substantially equal to or less than an amount of energy absorbable by a drop of printing fluid having the predetermined volume.
