Abstract
A printer switches between and uses plural communication units according to the operating mode, can switch the operating mode appropriately to the operating conditions, and can improve power conservation. The printer has a network control unit with a first communication unit configured to communicate in a first operating mode; and a main control unit having a second communication unit configured to communicate in a second operating mode. The main control unit limits the power supply to the first communication unit in the second operating mode; and the second communication unit determines whether or not to go to the first operating mode based on content of data received in the second operating mode.
Claims18
A control method of device printer configured to be able to communicate with an external device and to have a first communication unit configured to communicate with the external device in a first operating mode, and a second communication unit configured to communicate with the external device in a second operating mode, the control method comprising:
- limiting the power supply to the first communication unit in the second operating mode;
- and
- the second communication unit determining whether or not to go to the first operating mode based on content of data received in the second operating mode.
A printer comprising:
- a network control unit configured to be able to communicate with an external device and to have a first communication unit configured to communicate with the external device in a first operating mode;
- a main control unit having a second communication unit configured to communicate with the external device in a second operating mode;
- the main control unit limiting the power supply to the first communication unit in the second operating mode;
- and
- the second communication unit determining whether or not to go to the first operating mode based on content of data received in the second operating mode.
A storage medium storing a program causing a control device of a printer configured to be able to communicate with an external device and to have a first communication unit configured to communicate with the external device in a first operating mode, and a second communication unit configured to communicate with the external device in a second operating mode, to execute a process, the program causing the control device to execute steps of:
- limiting the power supply to the first communication unit in the second operating mode;
- and
- the second communication unit determining whether or not to go to the first operating mode based on content of data received in the second operating mode.
