| 摘要 |
A printing apparatus includes a first detection terminal and a second detection terminal which contact with respective two first terminals of each of printing material containers; a third detection terminal and a fourth detection terminal which contact with respective two second terminals of each of the printing material containers; a first detection unit detects a first detection signal from the first detection terminal via a first attachment detection path; and a second detection unit detects a second detection signal from the third detection terminal via a second attachment detection path. The first detection unit detects a short circuit occurring between the second detection terminal and the third detection terminal on the basis of the second detection signal, and the second detection unit detects a short circuit occurring between the first detection terminal and the fourth detection terminal on the basis of the first detection signal.
