Image apparatus, recording apparatus, and recording system, and control method and program thereof

摘要

After applications installed in a DSC and PD printer establish a communication procedure, the DSC issues a request to the PD printer. A time required for data transfer involved in the request is predicted. An elapse time until a response is received from the PD printer in response to the request is estimated on the basis of the predicted time. If no response is returned from the PD printer within the estimated elapse time, the request is disabled.
