A device for creating print data utilized by a printer is disclosed. The print data includes a coordinate at which a dot is to be formed on a print medium by the printer. The print data creating device is provided with a first device and a second device. The first device chooses a first coordinate from bit-mapped data. The bit-mapped data includes a plurality of combinations of the first coordinate and color information. The first device chooses the first coordinate based on the color information being combined with the first coordinate. The second device creates the print data by converting the first coordinate chosen by the first device into at least two second coordinates which are randomly chosen from at least three second coordinates located in the neighborhood of the first coordinate.
