ABSTRACT:
In a printing apparatus which must periodically execute maintenance operation after activation and has a timer that counts the time on the basis of power supplied from a battery and has a register in which a flag is written when an abnormality occurs in the battery, the internal time is so set as to be counted up on the basis of time read out from the timer. When the flag is written in the register upon activating the apparatus, information representing occurrence of the abnormality is written in a nonvolatile storage. Predetermined time is set as the internal time, the flag is cleared, and execution of maintenance operation is designated on the basis of the internal time.
