Abstract
If an optional paper feeding deck or furnisher, or paper stacker, is connected to an image forming apparatus (such as a printer), such optional devices are to be controlled by connecting the paper conveyance control apparatus to control those options. Such an image forming apparatus has a video controller to convert the printer language sent from a high-order device such as a host computer, into bit map data and a printer engine to print the bit map data. Such a paper conveyance control apparatus, being electrically connected to the video controller, has a memory to be shared with the video controller. The video controller writes the job schedule in the shared memory. The paper conveyance control apparatus controls the optional device according to the written job schedule.
