Abstract:
A printing apparatus comprising a storage unit having a driving unit, determines whether or not access to the storage device is required with reception of data; determines whether or not a predetermined period of time has elapsed after transition to a first operation state; in a case where the predetermined period of time has elapsed, obtains, as an estimation time, a period of time until next reception of data that requires access to the storage device based on history information; and causes the printing apparatus to transition from the first operation state to a second operation state in a case where the estimation time exceeds a threshold of a period of time decided based on an amount of power consumption for when the driving unit is driven, and maintain the printing apparatus in the first operation state in a case where the estimation time does not exceed the threshold.
