摘要: A personal computer (20A) has a print image developing means (641A) and a data compression means (642A) including a fixed rate compression. A color printer (21A) has a data extension means (921A), a color correction means (922A), a gamma correction means (924A), a first halftoning means (925A), an image area segmentation means (926A), and a second halftoning means (927A). A transmission time of a print image can be shortened necessarily less than a constant time, and further since an enormous memory for an extension is unnecessary, a low cost printer can be provided.
