Abstract: A printing system has a printing apparatus and a host apparatus. Print data or control data is transferred between the printing apparatus and the host apparatus in accordance with at least two transfer methods. Upon detecting that a specific state has passed, the printing apparatus or the host apparatus predicts a change of the transfer method when (or immediately after) the specific state has passed. An analysis is conducted to determine whether the transfer method has been changed for the data subsequently transferred. If it is found that the transfer method used in the printing apparatus or the host apparatus has been changed, the other apparatus accordingly changes the transfer method. On the other hand, if the transferred data is based on the currently used method, the method is not changed, but is maintained.

Abstract: There is provided a data communication system capable of effectively executing multi-polling communication. In case of multi-polling communication between a polling-transmitter and a polling-receiver, the polling-transmitter declares the presence or absence of the multi-polling transmission function by a DIS signal, and the polling-receiver informs, by a DTC signal, whether polling reception of different information is requested in succession to the previously designated information. In response, the polling-transmitter is adapted, after the transmission of a document designated by a SEP signal, to transmit an EOS signal in case the polling reception of different information is requested, but to transmit an EOP signal in case such polling reception of different information is not requested.
