In case of searching and outputting output information stored in a memory, it enables a user of the host computer to select the device of storing the output information, whereby the load in searching and outputting the information is reduced. To do so, when the host computer causes the printer to print the image based on the print data, the hard disk of the multifunctional device is selected from among the plural hard disks, as the storage destination to which the print data is stored and from which the stored print data can be searched and output. Then, the information representing the storage destination and the print data are transmitted to the printer so as to be printed, and the print data is also transmitted to the multifunctional device to be stored.
