ABSTRACT:
A laser beam printer comprises a frame memory of one page part and a compression means for compressing a dot data in the frame memory. The compression means compresses to make a compressed and encoded data. The laser beam printer comprises further a memory operable for storing dividedly a plural pages part of the compressed and encoded data and an extension means for decoding and extending the encoded data in the memory by synchronizing with a printing timing. The data compression in the frame memory and the decoding/printing of the dot data in the encoded data memory carries out in parallel. A printing in the laser beam printer can be realized at a high speed.
