  • Publication number: 20050182622
    Abstract: A state of a system, such as a printer or wireless device set, is monitored and sound information corresponding to the state of the system is output. An output mode for output sound information can be set by a user to a mode (e.g., silent mode) in which the sound information output manner is controlled by the user. When the sound information corresponding to the operation state of the system is acquired, if the output mode for the sound information is set to the silent mode, the acquired sound information is silenced, and the silenced sound information is output.
