Abstract
A control apparatus including a power supply unit configured to supply electric power, comprises: a capacitor connected to a power supply line extending from the power supply unit to a printhead; a discharge circuit configured to release charge stored in the capacitor; and a control unit configured to control a current value during a discharge operation by the discharge circuit, such that the current value increases as a voltage value of the capacitor decreases.
