Abstract
A printhead mainly includes at least two ink supply holes on a single semiconductor substrate, a first signal processing circuit laid out at at least one corner of the semiconductor substrate to arbitrarily select a heater for heating the ink, and a second signal processing circuit, other than the first signal processing circuit for arbitrarily selecting a heater, that realizes a function without dividing an arrangement. The lengths of signal lines are minimized to realize a printhead free from any malfunction.
