Text information processing apparatus having printer and printing dot signal generating apparatus for the same.

摘要

A laser beam printer comprises a frame memory (261) of one page part and a compression means (250) for compressing a dot data in the frame memory. The compression means compresses to make a compressed and encoded data. The laser beam printer (300) comprises further a memory operable for storing dividedly a plural page part of the compressed and encoded data and an extension means (250) for decoding and extending the encoded data in the memory in synchronism with a printing timing. The data compression in the frame memory and the decoding/printing of the dot data in the encoded data memory is carried out in parallel. Printing in the laser beam printer (300) can be realized at a high speed. <IMAGE>
