Abstract
A printing apparatus which shuts off the power supply to the apparatus, if a state in which the power supply to the apparatus is meaningless continues for a predetermined period, to prevent wasteful electricity consumption. When a LBP has an abnormality, an error processor detects the abnormality, executes a predetermined processing such as notification of the occurrence of error, and outputs error information to a power controller. The power controller determines whether or not the abnormal state has continued for a predetermined period. If the power controller determines the continuation of the abnormality for the predetermined period, it outputs a power-off instruction to a power. The power shuts off the power supply to the respective elements of the LBP.
