Abstract:
1. A print control device comprising: a processor; and a memory that stores a computer program that, when executed by the processor, causes the control device to function as: an acquiring unit configured to acquire image data representing an image including a plurality of pixels, the image data including a plurality of pixel data corresponding to the plurality of pixels, each of the plurality of pixel data including a gradation value; an executing unit configured to execute an error diffusion process on each of the plurality of pixel data, the executing unit including: an output unit configured to output print data determined by the dot value for each of the plurality of pixel data, wherein the first random number range corresponding to the gradation value smaller than the second threshold value includes a specific random number such that the first correcting unit corrects the gradation value included in the first range into the first corrected gradation value greater than the second threshold value by using the specific random number in the first random number range, the first range being greater than a first gradation value and smaller than the second threshold value, the first gradation value being greater than the first threshold value and smaller than the second threshold value.
