See full text

A printing device includes a printing material container, a controller and a voltage applying unit. The printing material container has a storage device, a plurality of terminals for the storage device, and first and second attachment detection terminals. The storage device stores information of the amount of a printing material. The controller is connected to the plurality of terminals for the storage device and controls reading or writing of data from or in the storage device. The voltage applying unit applies a voltage for detection of attachment to the first attachment detection terminal. When the voltage applying unit applies the voltage for the detection of the attachment to the first attachment detection terminal, the controller sets the terminals for the storage device to a high impedance state.
