ABSTRACT:
Disclosed is an image recording apparatus which records received printing data as n-tone image data under ordinary conditions but which is capable also of recording the data as m-tone (m<n) image data. When the tone image based upon the received printing data is recorded on a recording medium, the memory capacity usable for recording the image is compared with the memory capacity needed for recording, and it is decided, based upon the comparison, whether to record the image in n tones or m tones.
