Abstract
A data transmission system where an image providing device and a printer are directly connected by a 1394 serial bus, a command is sent from the image providing device to the printer, then a response to the command is returned from the printer to the image providing device. Image data is sent from the image providing device to the printer based on information included in the response. The printer converts the image data outputted from the image providing device into print data. Thus, printing can be performed without a host computer by directly connecting the image providing device and the printer by the 1394 serial bus or the like.
