PRINTING SYSTEM, PRINTER, DATA TRANSMISSION DEVICE, PRINTING METHOD, AND DATA TRANSMITTING METHOD CAPABLE OF SPECIFIC HIGH-SPEED OPERATION WITH IEEE1394 INTERFACE

摘要

PROBLEM TO BE SOLVED: To obtain a necessary data transfer rate even when a bus is congested owing to the operation of other devices in a specific high-speed operation such as printing operation between adjacent devices and to perform printing operation without any waste of time, i.e., a wait for other devices to complete a communication and without lowering the resolution of printed matter. ;SOLUTION: It is judged whether or not the specific high-speed printing is possible between devices connected by IEEE1394 interfaces 21 and 22 and a specific bus reset output means outputs a specific bus reset signal to the IEEE1394 interfaces 21 and 22 connected to the devices which are unable to perform the specific high-speed printing to temporary suspend or stop a current communication. In this period, the high-speed printing is performed between the devices which are able to perform the specific high-speed printing and after the printing, the specific bus resetting is reset to restart the communication before the specific bus resetting.;COPYRIGHT: (C)2000,JPO
