PROBLEM TO BE SOLVED: To provide a printing apparatus which hardly generates streak-like printing fluctuation on a recording medium. SOLUTION: The printing apparatus includes: p pieces of liquid delivering heads which are equipped with a liquid delivering hole group consisting of n pieces of liquid delivering holes and n pieces of pressing parts, and in which the liquid delivering holes are arranged two-dimensionally in one direction at equal intervals d; a conveying means for conveying a printing medium in a direction orthogonal to the one direction; and a controlling unit for controlling the pressing parts so that a pixel group arranged in one direction in parallel at equal intervals d with liquid droplets delivered from one liquid delivering head is formed, and pixel groups formed by p pieces of the liquid delivering heads are formed in one direction by shifting them d/p by d/p, to form one line consisting of the pixels parallel in one direction. P pieces of the liquid delivering heads are arranged in a direction orthogonal to one direction, and are arranged so that the integer part i when the amount to shift the mutual position in one direction is divided by d becomes either one of 1 to n-1.
