ABSTRACT:
Efficient image transmission is performed upon determining, based upon information sent from a receiving side at the time of negotiation, whether the apparatus on the receiving side is capable of progressive build-up, pseudo-progressive build-up in stripe units, sequential build-up or more than one of these build-up methods. Examples of the information sent from the receiving side include an instruction entered on the receiving side, the type of printer, the stripe width if the printer is capable of stripe printing, the communication speed and the memory capacity, etc. It is possible to use information from a line or network as well. This arrangement makes it possible to transmit image data that has been coded efficiently. Outstanding effects are obtained in multiple-address communication.
