Printing apparatus and control method therefor

摘要

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.

主权项

1. A printing apparatus comprising:
a storage unit; a driving unit for driving the storage unit; a first determination unit configured to, in a case where first data that is not print data is received, determine whether or not access to the storage unit is required with reception of the first data; a control unit configured to cause the printing apparatus to execute transition from a sleep state to a first operation state in a case where the first determination unit determined that the access to the storage unit is required with reception of the first data, wherein power consumption of the first operation state is lower than power consumption of a normal operation state and the storage unit is turned on in the first operation state, and wherein power consumption of the sleep state is lower than power consumption of the first operation state; a reception unit configured to receive second data which requires access to the storage unit; a history information management unit configured to manage a first history information relating to time of reception of the first data and a second history information relating to time of reception of the second data; and an estimation unit configured to calculate an estimation time which is a period of time until a next reception of data that requires access to the storage unit, based on a difference between the first history information and the second history information, wherein the control unit causes the printing apparatus to execute 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 driving the driving unit, wherein power consumption of the second operation state is lower than that in the normal operation and the storage device is turned off in the second operation state, wherein the control unit causes the printing apparatus to maintain in the first operation state in a case where the estimation time does not exceed the threshold.
