Abstract:
1. A communication system including a transmission apparatus configured to transmit output data and a reception apparatus configured to receive the output data, the transmission apparatus and the reception apparatus configured to communicate with each other, wherein the reception apparatus comprises: an output unit configured to execute an outputting procedure based on the output data received from the transmission apparatus; an abnormal state notification unit configured to transmit abnormal state notification data indicating the abnormal state when the output unit cannot execute the outputting procedure normally to the transmission apparatus; and a retransmission requesting unit configured to transmit retransmission request data requesting for retransmission of the output data if the outputting procedure is not executed normally, wherein the transmission apparatus comprises: an output data transmitting unit configured to transmit the output data to the reception apparatus; a transmission terminating unit configured to terminate transmission of the output data output by the output data transmitting unit if the abnormal state notification data is received from the reception apparatus; and an output data retransmitting unit configured to transmit the output data requested by the retransmission requesting unit to the reception apparatus when the retransmission request data is received; wherein the output unit is configured to print images corresponding to the output data on a recording medium, wherein the output unit is configured to start execution of the outputting procedure of the output data, while the reception apparatus is receiving the output data, and wherein the abnormal state notification unit is configured to transmit the abnormal state notification data to be received by the transmission terminating unit, when the output unit cannot execute the outputting procedure normally, while the reception apparatus is receiving the output data.
