Abstract
A host computer is connected to a plurality of printers via an IEEE1394 bus. To make these printers print an identical image, the host computer assures a communication channel. The host computer then broadcasts print data to the printers to make them print images. In this case, the host computer starts transmission after it confirms that all the printers are ready to print and to receive print data. Upon receiving a busy response from any printer, the host computer pauses data transmission.
