Abstract
A printing device includes: a printing material container that includes first and second short circuit detection terminals, first and second attachment detection terminals; a high voltage power supply that applies a high voltage to the first attachment detection terminal; a short circuit detector that detects a short circuit between at least one of the first and second short circuit detection terminals and at least one of the first and second attachment detection terminals; a high voltage application controller that blocks supply of the high voltage from the high voltage power supply when the short circuit detector detects the short circuit; a resistor element that is arranged between the high voltage power supply and the first attachment detection terminal; and an electrostatic capacitor element that is arranged between the detection node of the short circuit detector and a low-potential-side power supply node.
