Patent Number: 6,298,405

Title: Data communication system, printing system and data communication apparatus

Abstract: Disclosed are a data communication method whereby a first and a second node are directly connected so that they can exchange data directly, data communication apparatuses therefor, and a communication system that includes the apparatuses. A VTR and a printer are connected by an IEEE 1394 cable. When the printer requests the transmission of image data, the VTR transmits pertinent image data to the printer. Since the entry of a predetermined instruction at the operating unit of the VTR is inhibited during the transmission of image data, the occurrence of an obstacle to the transmission of image data can be prevented.
