In an external print controller added to an MFP, bit map data obtained by analyzing and developing received PDL data is once compressed and, subsequently, transferred via a PCI bus. In the compressed bit map data, the data in a compressed state is stored onto an HD in the MFP as it is. The compressed bit map data is read out from the HD, decompressed, and sent to a printer unit.

To provide data storage control apparatus and method capable of performing plural processes including processes that data are required to be processed in real time, without increasing cost and decreasing productivity, a RAM for storing data, a hard disk (HD) for storing data, a printer for printing an image, a scanner for reading an image, a facsimile for performing memory transmission/reception, and a CPU are provided. The CPU performs control to use the RAM if high speed is required and capacity is not so required, to use a high-speed accessible area in the HD if predetermined speed is required and capacity is required, and to use a low-speed accessible area in the HD if required speed may be low and capacity is required. In the control unit of a copying machine having the HD including plural storage areas of different access speeds, the predetermined storage area is selected from among these areas according to the purpose of image data to be stored in the HD, and the data is stored in the selected area. To increase the productivity of the process that the data are required to be processed in real time, the control unit performs control that a dummy access to the HD is automatically performed according as a second predetermined time shorter than a first predetermined time elapses from a time when the access to the HD terminates, so as to maintain rotation of the HD.

Each of input and output devices previously forms device profile, and a host computer acquires virtual input/output device information including a pair of ideal input and output devices on the basis of the device profiles of these devices. If the virtual input/output device information is acquired, the input device demands to acquire a transfer path profile included in the virtual input/output device information, and then demands if the transfer path profile is acquired the output device registered in the acquired transfer path profile to connect a line. If the line connection is established, the input device performs data inputting such that the acquired transfer path profile is reflected in the device setting, and then it transfers the input data to the desired output device.
