PROBLEM TO BE SOLVED: To realize automatic processing of continuous print out by measuring the elapse of time informed from an informing process and transmitting a data at an interval of measured time when a print out data is delivered continuously from an information unit to a printer. SOLUTION: When print-out of a plurality of pages is requested from a digital still camera(DSC) 1 to a printer 2, the DSC 1 delivers a connection request protocol at first to the printer 2 and then delivers a data from the first page when a connection acceptance protocol is delivered to the DSC 1. The printer 2 calculates a time T1 required for printing from the communication rate, the output sheet size, or the like, included in the connection request protocol and the size or the number of colors of the print out data included in a print data delivery protocol before starting print out. Upon elapsing the time T1, the DSC 1 delivers the data of next page. |
