Electronic device and method for printing based on information written by an external device in a power-off state

摘要

An electronic device comprises: a management unit configured to manage device information of the electronic device by storing the device information in a first storage unit; a communication unit configured to communicate with an external device according to short distance wireless communication; a storage control unit configured to control, when the electronic device transits from a power-on state to a power-off state, to write the device information stored in the first storage unit in a second storage unit; and a control unit configured to control, upon receiving a read request or write request of the device information from the external device via the communication unit, to read or write the device information stored in the second storage unit when the electronic device is in the power-off state.

1. An electronic device comprising:
a first communication unit configured to perform short distance wireless communication with an external device for performing a read or write operation on a first storage unit with information for acquiring print data by the external device even when said electronic device is in a power-off state, wherein the first communication unit operates in a card emulation mode for communicating with the external device that operates in a reader/writer mode; a second communication unit configured to acquire print data; a printing unit configured to print the print data acquired by said second communication unit; and a control unit configured to control said second communication unit to acquire the print data in accordance with the information for acquiring the print data and said printing unit to print the print data acquired by said second communication unit when said electronic device transits from a power-off state to a power-on state and the information for acquiring the print data has been written in the first storage unit by the external device via said first communication unit during the power-off state, wherein at least one of the units is implemented by a CPU executing computer-executable code stored in a non-transitory computer-readable memory.
