Inversely, the computer inquires the printer of color space and presence/absence of a color space conversion function. If the printer has the color space conversion function, the computer transmits color image data with parameters obtained from operation of parameters for converting the color space of the image data into the color space of the printer and the parameters received from the scanner.
