Benefits of technology

The present invention is about a way to automatically switch the communication mode of a device based on its own operation. This means that even if someone has forgotten to switch the mode, the device will automatically return to the default mode, which prevents another user from being unable to use the device in that mode.

Problems solved by technology

However, such a printing apparatus has a problem in that if a given user forgets to return the communication mode to the infrastructure mode after temporarily using Wi-Fi Direct, other users who have been using the printing apparatus in the infrastructure mode will be rendered unable to use the printing apparatus.
In such a situation, there is a problem in that a user who is using the printing apparatus through wireless communication in the infrastructure mode will be rendered unable to use the printing apparatus.

first embodiment

[0070]A first embodiment describes a case where the operation state of the printing apparatus 100 shifts from the normal power state (a non-power saving state) to a power saving state (for example, a sleep state) in which the printing apparatus 100 consumes a lower amount of power than in the normal power state. In the present embodiment, the normal power state (a first state) is the non-power saving state, and corresponds to a normal operation state in which power is supplied to a plurality of devices provided in the printing apparatus 100. On the other hand, the power saving state (a second state) corresponds to a state in which the power consumed by the printing apparatus 100 is reduced by supplying power only to some of the stated plurality of devices.

[0071]Hereinafter, a process for switching the communication mode according to the present embodiment, executed by the printing apparatus 100, will be described with reference to the flowchart shown in FIG. 5. Note that the printin...

second embodiment

[0087]If, for example, a power switch (not shown) is switched off while the printing apparatus 100 is operating in a state where the communication mode is set to the second wireless communication mode (Wi-Fi Direct), the printing apparatus 100 shifts from an activated state to a shut down state. In this case, if the power switch of the printing apparatus 100 is then turned on, the printing apparatus 100 will be activated in a state in which the communication mode is the second wireless communication mode (Wi-Fi Direct). In other words, a situation can arise in which a user who has connected to and is using the printing apparatus 100 in the first wireless communication mode is rendered unable to use the printing apparatus 100 until the communication mode of the printing apparatus 100 is returned to the first wireless communication mode from the second wireless communication mode.

[0088]Accordingly, a second embodiment describes an example in which the communication mode is automatical...

third embodiment

[0099]As described above, the printing apparatus 100 includes an authentication function for permitting the printing apparatus 100 to be operated by a user whose login authentication has succeeded. Normally, only users whose login authentications have succeeded can operate the console 211 of the printing apparatus 100 and, by extension, the printing apparatus 100 itself. When the user completes a desired task using the console 211 and a logout process is performed for that user, that user is once again rendered unable to operate the console 211. Such login authentication is carried out by, for example, providing a card reader in the printing apparatus 100 and using card-based authentication, accepting the input of a username and a password, or the like.

[0100]In the case where the printing apparatus 100 includes such an authentication function, the user can log into the printing apparatus 100, switch the communication mode of the printing apparatus from the first wireless communicati...

Abstract

A communication apparatus (a printing apparatus 100) according to an aspect of the present invention controls communication with an external apparatus in one of a first wireless communication mode (or a wired communication mode) and a second wireless communication mode. In the case where the communication mode is set to the second wireless communication mode, the printing apparatus 100 switches the communication mode to the first wireless communication mode (or the wired communication mode) when an operation state of the printing apparatus 100 shifts to another state such as a power saving state.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to communication apparatuses capable of wireless communication with an external apparatus such as a mobile terminal, a PC, or the like, and to control methods thereof, printing apparatuses, and storage media.[0003]2. Description of the Related Art[0004]Recent years have seen an increase in printing apparatuses, such as multifunction peripherals, printers, and the like, that include wireless LAN functionality. A printing apparatus that includes wireless LAN functionality can connect wirelessly to an access point as a client using an infrastructure mode. Meanwhile, by using the infrastructure mode to communicate with the printing apparatus via the access point, PCs, mobile terminals, and the like can cause the printing apparatus to execute printing by sending print data thereto, and the PCs, mobile terminals, and the like can then be used to manage the printing apparatus by receiving device i...
