Abstract
A printing apparatus includes a printer engine and a network interface. A first controller communicates with the network interface, and a second controller controls power supply to the printer engine and the first controller. The first controller, when the printing apparatus makes a transition to a power-saving state, causes the network interface to be in a first sleep state or a second sleep state from the normal operation state and instructs the second controller to stop power supply to the first controller. The second controller supplies power to the first controller when the printing apparatus resumes from the first sleep state, and supplies power to the first controller and the printer engine when the printing apparatus resumes from the second sleep state.
Claims23
A printing apparatus comprising:
- a printer engine;
- a network interface which can change a link speed, and which receives data from an external apparatus;
- a first controller which controls communication with the network interface;
- a second controller which controls power supply to the printer engine and the first controller,
- wherein
- the first controller causes the printing apparatus to make a transition to a first sleep state or a second sleep state,
- the first sleep state is a sleep state in which the second controller stops power supply to the first controller and the printer engine, and the link speed of the network interface is a first link speed,
- the second sleep state is a sleep state in which the second controller stops power supply to the first controller and the printer engine, and the link speed of the network interface is a second link speed lower than the first link speed, and
- the second controller
- in a case where the printing apparatus is in the first sleep state, supplies power to the first controller by receiving data from the external apparatus, and
- in a case where the printing apparatus is in the second sleep state, supplies power to the first controller and the printer engine by receiving data from the external apparatus.
A control method of a printing apparatus, wherein the printing apparatus comprises:
- a printer engine;
- a network interface which can change a link speed, and which receives data from an external apparatus;
- a first controller which controls communication with the network interface;
- and
- a second controller which controls power supply to the printer engine and the first controller,
- the control method comprising the steps of:
- controlling the first controller to transition the printing apparatus to a first sleep state or a second sleep state,
- the first sleep state is a sleep state in which the second controller stops power supply to the first controller and the printer engine, and the link speed of the network interface is a first link speed,
- the second sleep state is a sleep state in which the second controller stops power supply to the first controller and the printer engine, and the link speed of the network interface is a second link speed lower than the first link speed,
- controlling the second controller, in a case where the printing apparatus is in the first sleep state, to supply power to the first controller by receiving data from the external apparatus, and
- controlling the second controller, in a case where the printing apparatus is in the second sleep state, to supply power to the first controller and the printer engine by receiving data from the external apparatus.
A non-transitory computer readable storage medium storing a program for causing a computer to perform a control method of a printing apparatus, wherein the printing apparatus comprises:
- a printer engine;
- a network interface which can change a link speed, and which receives data from an external apparatus;
- a first controller which controls communication with the network interface;
- and
- a second controller which controls power supply to the printer engine and the first controller,
- the control method comprising the steps of:
- controlling the first controller to transition the printing apparatus to a first sleep state or a second sleep state,
- the first sleep state is a sleep state in which the second controller stops power supply to the first controller and the printer engine, and the link speed of the network interface is a first link speed,
- the second sleep state is a sleep state in which the second controller stops power supply to the first controller and the printer engine, and the link speed of the network interface is a second link speed lower than the first link speed,
- controlling the second controller, in a case where the printing apparatus is in the first sleep state, to supply power to the first controller by receiving data from the external apparatus, and
- controlling the second controller, in a case where the printing apparatus is in the second sleep state, to supply power to the first controller and the printer engine by receiving data from the external apparatus.
