Abstract

A printing system includes a printing control apparatus and a printing apparatus. The printing apparatus includes a receiving unit that receives data transmitted from the printing control apparatus, and a power source control unit that causes the printing apparatus to enter a first power saving state or a second power saving state. The printing control apparatus includes an acquisition unit that acquires a power state of the printing apparatus, and a control unit that causes the printing control apparatus to enter an OFF state in a case where a acquired power state is the first power saving state, and causes the printing control apparatus to enter a power saving state where a wake-up packet for recovering the printing apparatus from the second power saving state can be transmitted in a case where the acquired power state is the second power saving state.

First claim

What is claimed is:

1. A printing system including a printing control apparatus which generates image data, and a printing apparatus which is able to connect to the printing control apparatus and performs printing by using the image data transmitted from the printing control apparatus,
wherein the printing apparatus comprises:
a first processing unit configured to control the printing apparatus;
a memory unit configured to store data processed by the first processing unit;
a first network interface unit configured to communicate with the printing control apparatus; and
a power source control unit configured to shift the printing apparatus to a first power saving state in which power is not supplied to the first processing unit and the first network interface unit and power is supplied to the memory unit,
wherein the first network interface unit is configured to, based on a first condition for shifting the printing apparatus to the first power saving state being satisfied, transmit first information to the printing control apparatus, and
wherein the printing control apparatus comprises:
a second network interface unit configured to receive the first information transmitted by the first network interface unit; and
a second processing unit configured to turn off the printing control apparatus in accordance with receiving the first information.

2. The printing system according to claim 1 , wherein the power source control unit shifts the printing apparatus to a second power saving state in which power is not supplied to the first processing unit and power is supplied to the memory unit and the first network interface unit,
wherein the first network interface unit does not transmit the first information to the printing control apparatus based on a second condition for shifting the printing apparatus to the second power saving state being satisfied.

3. The printing system according to claim 2 , wherein
the first network interface unit configured to, based on the second condition being satisfied, transmit second information to the printing control apparatus in order to shift the printing control apparatus to a third power saving state.

4. The printing system according to claim 3 , wherein the first network interface unit transmits third information in order to recover the printing control apparatus from the third power saving state when the printing apparatus recovers from the second power saving state.

5. The printing system according to claim 1 , wherein the memory unit stores working statuses of the printing apparatus in the first power saving state.

6. The printing system according to claim 1 , wherein the second processing unit performs shutdown processing for the printing control apparatus and then turns off the printing control apparatus.

7. The printing system according to claim 1 , wherein the printing apparatus further comprises a seesaw switch configured to be turned ON or OFF according to a user operation,
wherein, the first network interface unit transmits the first information based on the seesaw switch being turned OFF by the user operation, and then the power source control unit shifts the printing apparatus to the first power saving state.

8. The printing system according to claim 7 , wherein the printing apparatus further comprises a storage unit configured to store setting information indicating a power state to be shifted when the seesaw switch is turned OFF,
wherein, in a case where the seesaw switch is turned OFF by the user operation and the setting information indicates the first power saving state, the power source control unit shifts the printing apparatus to the first power saving state, and
in a case where the seesaw switch is turned OFF by the user operation and the setting information indicates a power off state, the power source control unit turns off the printing apparatus.

9. The printing system according to claim 1 , wherein the first network interface unit transmits second information in order to recover the printing control apparatus which has been turned off when the printing apparatus recovers from the first power saving state.

10. The printing system according to claim 1 , wherein the first processing unit is a main processor of the printing apparatus, and the memory unit is a main memory of the main processor.

11. The printing system according to claim 1 , wherein the first power saving state is a suspend state.

12. A printing control apparatus for generating image data, which is able to connect to a printing apparatus, wherein the printing apparatus has a printer unit configured to perform printing by using the image data, a first processing unit configured to control the printing apparatus, a memory unit configured to store data processed by the first processing unit, a first network interface unit configured to communicate with the printing control apparatus, and a power source control unit configured to shift the printing apparatus to a first power saving state in which power is not supplied to the first processing unit and the first network interface unit and power is supplied to the memory unit, and the first network interface unit is configured to transmit first information to the printing control apparatus based on a first condition for shifting the printing apparatus to the first power saving state being satisfied,
the printing control apparatus comprising:
a second network interface unit configured to receive the first information transmitted by the first network interface unit; and
a second processing unit configured to turn off the printing control apparatus in accordance with receiving the first information.

13. The printing control apparatus according to claim 12 , wherein the second processing unit performs shutdown processing for the printing control apparatus and then turns off the printing control apparatus.

14. A printing system including a printing control apparatus which generates image data, and a printing apparatus which is able to connect to the printing control apparatus and performs printing by using the image data transmitted from the printing control apparatus,
wherein the printing apparatus comprises:
a first processing unit configured to control the printing apparatus;
a memory unit configured to store data processed by the first processing unit;
a first network interface unit configured to transmit information to the printing apparatus; and
a power source control unit configured to shift the printing apparatus to a first power saving state in which power is not supplied to the first processing unit and the first network interface unit and power is supplied to the memory unit, and
wherein the first network interface unit transmits first information to the printing control apparatus based on a first condition being satisfied, and then the power source control unit shifts the printing apparatus to the first power saving state, and
wherein the printing control apparatus comprises:
a second network interface unit configured to receive the first information transmitted by the first network interface unit; and
a second processing unit configured to turn off the printing control apparatus in accordance with receiving the first information.

15. The printing system according to claim 14 , wherein the power source control unit shifts the printing apparatus to a second power saving state in which power is not supplied to the first processing unit and power is supplied to the memory unit and the first network interface unit,
wherein, based on a second condition being satisfied, the first network interface unit does not transmit the first i
