A printing apparatus that discharges liquid droplets onto a recording medium, includes a movable carriage; discharging units, which are installed on the carriage and include nozzles that discharge a liquid, pressure chambers that communicate with the nozzles, and piezoelectric elements provided for each of the pressure chambers; a first circuit substrate, which is installed outside of the carriage, and on which is installed a control signal supply unit that generates control signals; a second circuit substrate, which is installed on the carriage, and on which are installed a booster circuit that generates a plurality of voltages; in which a path length of the control wiring between the first circuit substrate and the second circuit substrate is longer than the path length of the wiring between the second circuit substrate and the piezoelectric elements. |
