<p>An ink jet recording apparatus includes a color ink recording head 6 having nozzle openings Nc arranged at pitch Pc in a paper feed direction as NXP (N is an integer of four or more being not a prime number) when pitch of dots required for print is P, and a black ink recording head 5 having m nozzle openings Nb1 (m is a divisor of two or more, of N) arranged at pitch Pb1 in the paper feed direction as P and nozzle openings Nb2 arranged at pitch Pb2 in the paper feed direction as äN-(m-1)üP. Paper feed is executed in units of mP and image data is printed by the color ink recording head 6 and text data is printed by the black ink recording head 5 at the same time. Accordingly, the text data and the image data existing in the same path can be printed at their respective optimum resolutions. <IMAGE></p> |
