<p>A command packet (C2) including a version command for checking a profile is sent from a data transmitter (STB) to a data receiver (printer), and a response packet (R2) including the resulting profile information is sent from the data receiver to the data transmitter. The data transmitter sends the data receiver a data packet (S2) including the image data corresponding to the profile information. Thus, a controller can quickly check the state of a device to be controlled.</p> |
