    • An image processing apparatus is controlled in accordance with the status of an interface and the contents of data. Specifically, so long as the number J of jobs, which are executed by the copier system at the same time, and the number N of channels, which are required by a target job during one cycle, are obtained, dynamic paper feeding timing Wd can be acquired from ideal paper feeding timing Ws, while taking delay time X into account. The preceding paper feeding is performed using paper feeding timing Wd. Further, based on predicted data, a check is performed to determine whether image transmission will be successful without a buffer memory being used. When it is determined that the buffer memory is not required for the image transmission, image data are received without the buffer memory being obtained. When it is determined that the buffer memory is required for the image transmission, an adequate buffer memory is acquired for the reception of image data. In addition, a check is performed to determine whether the height of an obtained bandwidth is satisfactory. When it is determined that the height of the bandwidth is satisfactory, a printer engine is so controlled that it performs printing at the maximum process speed (minimum paper interval).
    • 根据接口的状态和数据的内容来控制图像处理装置。 具体地说,只要在一个周期内同时由复印机系统执行的作业数J和目标作业所需的通道数N被获得,则动态供纸定时Wd可以 从理想的纸张馈送计时Ws中获取,同时考虑延迟时间X. 使用送纸定时Wd进行前一个送纸。此外,基于预测数据,执行检查以确定在不使用缓冲存储器的情况下图像传输是否成功。 当确定图像传输不需要缓冲存储器时,在没有获得缓冲存储器的情况下接收图像数据。 当确定图像传输需要缓冲存储器时,获取足够的缓冲存储器用于接收图像数据。此外,执行检查以确定所获得的带宽的高度是否令人满意。 当确定带宽的高度令人满意时,打印机引擎被如此控制,以最大处理速度(最小纸张间隔)进行打印。
