    摘要: An apparatus and method to adjust an alignment between scanning lines of a laser printer. The apparatus may include a laser scanning unit having a plurality of laser diodes and an adjustment unit to adjust a plurality of video data using an integer part and a decimal fraction part to synchronize with synchronization signals from the plurality of laser diodes, the integer part and the decimal fraction part constituting a real number that is calculated by using a video clock for synchronizing with the plurality of video data and the synchronization signals from the plurality of laser diodes scanning the plurality of video data. The apparatus and method compensate for an error occurring between the scanning lines due to the location differences of the respective laser diodes.

    摘要: A data compression and decompression unit that can enhance a data throughput during compression and decompression of data by dynamically allocating the sizes of the input and output buffers to the compression and decompression sections in accordance with a compressibility of data. The data compression and decompression unit includes a compression section that receives bit map data from a terminal, compresses the bit map data with a predetermined compressibility, and generates compressed data, and a decompression section that decompresses the compressed data into an original format, and generates decompressed data. The data unit further includes a memory section that stores the bit map data, the compressed data, and the decompressed data, and a control section that controls the compression and decompression in accordance with the predetermined compressibility.
