Abstract
A segmented heater resistor is provided for producing a variable ink drop volume in an inkjet drop generator. The segmented heater resistor includes multiple heater resistor segments to which a voltage may be selectively applied, resulting in a variable amount of energy dissipated by the segmented heater resistor, a variable amount of heat transferred to ink in the ink drop generator, and a variable ink drop volume expelled by the inkjet drop generator.
