ABSTRACT:
An apparatus for decoding a coded image into a pixel image and printing the pixel image at an essentially constant speed without using decoding means which decodes the coded image faster than a printing speed and pixel memory means for storing at least one page of pixel information. Decoding amount calculation means for calculating the decoding amount of the code to be decoded is provided, and compare means monitors whether the decoding amount exceeds the printing amount of the pixels to be printed and the code is converted to other code depending on the comparison result. The decoding means needs only receive the converted code from the code memory means and decode it to the pixel information. Thus, the constant speed printing apparatus is attained without high speed decoding means and one-page memory.
