An image processing device of the invention converts a resolution of input image data into a preset recording resolution and generates print data. In the image processing device of the invention, multiple halftoning process modules are provided corresponding to multiple different aspect ratios of recording resolutions as resolutions for image recording to respectively perform different halftoning processes according to the different aspect ratios. The image processing device sets one recording resolution among multiple recording resolutions, which include at least two different recording resolutions having an identical aspect ratio, and converts the resolution of the input image data according to the set recording resolution to generate multi-tone data representing tone values expressed in respective pixels of the image data. The image processing device selectively activates one of the multiple halftoning process modules corresponding to an identified aspect ratio of the set recording resolution to perform the corresponding halftoning process and convert the multi-tone data into dot state data, and outputs the dot state data in a predetermined order as the print data. This arrangement desirably reduces the total required memory capacity.
