Abstract
Disclosed are recording method and apparatus for inputting recording information in page units, developing the recording information into bit-map information and recording the bit-map information. The bit-map information is corrected, before it is compressed by a compressing circuit, in dependence upon the compression ratio of the compressing circuit, the corrected bit-map information is then compressed by the compressing circuit and stored in a pixel memory. Recording is performed upon expanding the bit-map information stored in the pixel memory. As a result, the blurring of characters and fine lines by compression can be prevented. Further, it is determined whether the recording information is text data or image data. By compressing the text data at a compression ratio smaller than that used to compress the image data, a decline in the image quality of the text data recorded is prevented.
