Abstract
Ink permeation with respect to paper differs in accordance with the temperature of the paper. As the temperature increases, the permeation increases, thus the ink immediately permeates into the paper as soon as it is attached to the paper. Accordingly, in a color ink-jet printer, upon printing, a portion in a print line of the paper is heated in accordance with control information corresponding to area designation information which is separate from print information. As ink quickly permeates at the heated portion, after printing with ink of a color, subsequent ink of another color does not mix with the previous color ink, thus bleeding can be prevented. Further, an area of character or the like is not heated, so that ink does not quickly permeate, thus feathering of outlines can be prevented.
