    • An image forming apparatus using a band buffering system and a printing method thereof prevents band overrun errors from being generated. The image forming apparatus includes: an interface unit for interfacing data transmitted between an external source and the image forming apparatus and a controller. The controller divides the data received by the image forming apparatus through the interface unit into a plurality of band blocks and estimates a conversion time for each one of the plurality of band blocks. The conversion time represents an amount of time required to convert the data corresponding to a respective one of the plurality of band blocks into bit map data. The controller reduces the speed of a motor that feeds paper during a printing operation when the conversion time for any one of the plurality of band blocks exceeds a standard time.
    • 使用带缓冲系统的图像形成装置及其打印方法防止产生频带超限错误。 图像形成装置包括:接口单元,用于在外部源和图像形成装置之间传输的数据和控制器进行接口。 控制器通过接口单元将由图像形成装置接收的数据划分成多个频带块,并且估计多个频带块中的每个频带块的转换时间。 转换时间表示将对应于多个频带块中的相应一个频带块的数据转换成位图数据所需的时间量。 当多个带块中的任一个的转换时间超过标准时间时,控制器降低在打印操作期间馈送纸张的电动机的速度。
