Claim of US Patent No. 9,288,355

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.
