ABSTRACT:
According to the invention, whether a print head of, for example, the thermal jet system has been capped or not is informed to the user, thereby preventing that the user turns off the power source when the head is not capped. Even when the user turns off the power source in spite of the fact that the head is not capped yet, the capping status is checked before the power source is turned off. After the head was capped, the power source is turned off. Due to this, it is prevented that the print head is left while the head is not capped yet. The choking of the nozzles can be prevented.
