[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention includes an optional unit connected to an image processing apparatus that controls an image processing apparatus that can connect any one of a plurality of optional units that execute predetermined function processing to an engine unit. The present invention relates to an image processing apparatus and a unit control method in an image processing system, a computer-readable storage medium, and a program.
[0002]
[Prior art]
Conventionally, various image processing systems connectable to a network have been proposed. These are defined in advance at the time of designing what kind of configuration is possible for the entire system, and by designing an image processing apparatus for processing PDL data based on Page Description Language (page description language), a PDL dedicated to black and white is designed. Assuming a case in which a device is designed and connected, or a sorter device and a finisher device are selected and connected, the operation procedure when the sorter device is connected in advance and the operation procedure when the finisher device is connected are described below. It is also incorporated in the design of the PDL controller device, using sorter control software when the sorter device is actually connected, and selecting and operating the finisher control software when the finisher is connected. , Which paper output device is connected Operation was designed to be.
[0003]
[Problems to be solved by the invention]
However, in the above-described control method using the optional connection device, it is necessary to previously incorporate software corresponding to all combinations of systems into the PDL device. Therefore, a new paper ejection device (such as a finisher or a stacker) that is not initially supposed to be used. ) Was created, it was necessary to recreate the software of the PDL controller.
[0004]
In addition, since the number of combinations of devices that need to be handled is extremely large, there is a problem that a memory capacity required for software is increased and a cost is increased.
[0005]
In addition, the printer driver which is software on the client side also needs to design a printer driver corresponding to all possible configurations, which is very troublesome.
[0006]
To avoid some of these problems, create a definition file for each system configuration with the controllable information of the entire system as a PPD file in order to stop creating different printer driver software for each system configuration. Attempts have been made to use a single printer driver in various systems. Note that the PPD file is a generic name of a file name developed by Adobe Inc. for using a general-purpose printer driver in various systems.
[0007]
However, the PDL for controlling the system needs to be designed in advance so as to correspond to all possible configurations of the system. In consideration of all possible configurations of the PPD file, a PPD file corresponding to each of them must be created in advance. In advance, the user needs to select and specify a PPD file that matches the image forming system that he / she wants to output. However, in the design of the PDL and the PPD file, it is necessary to assume all configurations. It took a long time to develop.
[0008]
Further, in order to cope with a combination of systems not expected at the beginning of the design, it was necessary to redesign the software of the PDL and create a PPD file suitable for a new system configuration.
[0009]
As a method of creating a PPD file, a user selects a system configuration of a system used by a user from a driver setting screen by creating a PPD file corresponding to all combinations of system configurations and incorporating the PPD file in a printer driver. In addition, there is also proposed and used an implementation method that enables selection of optional print functions that match the system configuration, but in any case, when designing a PDL or PPD, It was necessary to predetermine and design the configuration information related to the system combination.
[0010]
As such a proposal, there is a patent document US Pat. No. 6,196,559 B1 (Configuration Description Language system of EFI) and the like.
[0011]
Due to the above problems, it has not been possible to use a controller that has been designed in the past in combination with various configurations of engines and paper ejection options that were not originally designed. There is a problem that a typical OpenIF controller cannot be created.
[0012]
