ABSTRACT:
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.
