Information processing system, image input/output apparatus, and data processing method

An image input/output apparatus capable of communicating with another image input/output apparatus via a communication medium, comprising:

• a receiving unit configured to receive a job handle before transfer of a job;
• an identifying unit configured to identify a job held by an image input/output apparatus of a transfer source of the job based on the job handle received by said receiving unit;
• and
• a control unit configured to perform control so that a manipulation of the job identified by said identifying unit will be performed before transfer of the job.

A data processing method for an information processing system in which a plurality of image input/output apparatus can communicate with one another via a communication medium, the data processing method comprising:

• transferring a job from a first image input/output apparatus to a second image input/output apparatus;
• and
• generating a job handle used to identify a job on the first image input/output apparatus from the second image input/output apparatus, the job handle allowing the job to be manipulated, wherein
• when the job is to be transferred at said transferring, the job handle generated at said generating is transmitted from the first image input/output apparatus to the second image input/output apparatus before transfer of the job.
