DATA TRANSMITTING/RECEIVING DEVICE, DATA TRANSMITTING/RECEIVING METHOD AND PROGRAM

PROBLEM TO BE SOLVED: To improve throughput of a data transmitting/receiving device. SOLUTION: In a RAM, a buffer area is secured which is composed of a header area having the size of a header and a data area coupled to the header area (step S100). In the data area, received printing data are stored and a header is created in the header area (steps S110, S120). As transmission data, data immediately after the header area up to a predetermined size therein are transmitted together with the created header (step S130). If untransmitted printing data exists, a header area is secured just before the untransmitted printing data and a header is created in the header area (step S150). Until no untransmitted printing data remains, processes of the step S130 through step S150 are repeated. Thus, the throughput can be improved as compared with another device which copies same data more than once until received printing data are transmitted. COPYRIGHT: (C)2007,JPO&INPIT
