Abstract
A client inquires service information or ability information which are peculiar to a plurality of or a single peripheral device, manages those information in a storage so that they can be updated, and requests a service to the peripheral device which can respond to a desired service request.
Claims41
An information processing apparatus for connection to a peripheral device, comprising:
- discrimination means for discriminating whether a change notice received from an external source indicates a change in service of the peripheral device or a change in ability of the peripheral device;
- and
- obtaining means for obtaining service information showing a service of the peripheral device or ability information showing an ability of the peripheral device in response to a discrimination result by said discrimination means.
An information processing apparatus for connection to a peripheral device comprising:
- a controller for discriminating whether a change notice received from an external source indicates a change in service of the peripheral device or a change in ability of the peripheral device, and for obtaining service information showing a service of the peripheral device or ability information showing an ability of the peripheral device in response to a discrimination result.
An information processing method for connection to a peripheral device, comprising the steps of:
- discriminating whether a change notice received from an external source indicates a change in service of the peripheral device or a change in ability of the peripheral device;
- and
- obtaining service information showing a service of the peripheral device or ability information showing an ability of the peripheral device in response to a discrimination result of the discriminating step.
A storing medium to store a control program which can be executed by an information processing apparatus and is used for connection to a peripheral device, wherein said program comprises the steps of:
- discriminating whether a change notice received from an external source indicates a change in service of the peripheral device or a change in ability of the peripheral device;
- and
- obtaining service information showing a service of the peripheral device or ability information showing an ability of the peripheral device in response to a discrimination result of the discriminating step.
An information processing system for obtaining information of a peripheral device, comprising:
- notification means for providing a notice indicating that a service or an ability of the peripheral device has changed;
- discrimination means for discriminating whether the notice provided by said notification means indicates a change in service of the peripheral device or a change in ability of the peripheral device;
- and
- obtaining means for obtaining service information showing a service of the peripheral device or ability information showing an ability of the peripheral device in response to a discrimination result by said discrimination means.
A peripheral device connected to an information processing apparatus, comprising:
- detection means for detecting a change in service or a change in ability of said peripheral device;
- and
- control means for sending a change notice to the information processing apparatus in response to the change detected by said detection means.
A control method of controlling a peripheral device connected to an information processing apparatus, comprising the steps of:
- detecting a change in service or a change in ability of the peripheral device;
- and
- sending a change notice indicating the change in service or the change in ability to said information processing apparatus in response to a detection in said detecting step.
A storing medium to store a control program of controlling a peripheral device connected to an information processing apparatus, wherein said control program comprises the steps of:
- detecting a change in service or a change in ability of the peripheral device;
- and
- sending a change notice indicating the change in service or the change in ability to said information processing apparatus in response to a detection in said detecting step.
A peripheral device connected to an information processing apparatus, comprising:
- a controller for detecting a change in service or a change in ability of the peripheral device and sending a change notice indicating the change in service or the change in ability to said information processing apparatus in response to the detected change.
A control program provided in a storage medium executed by an information processing apparatus for connection to a peripheral device, comprising the steps of:
- discriminating whether a change notice received from an external source indicates a change in service of the peripheral device or a change in ability of the peripheral device;
- and
- obtaining service information showing a service of the peripheral device or ability information showing an ability of the peripheral device in response to a discrimination made in said discriminating step.
