Image processor that generates image data used in printing

A non-transitory computer readable storage medium storing a printer driver executable by an image processor, the printer driver causing the image processor to perform:

• acquiring target image data representing a target image, the target image including a plurality of objects, the plurality of objects including a first object having a first object size and a second object having a second object size;
• selecting one of a first printing quality and a second printing quality, printing the target image with the second printing quality consuming more colorant than printing the target image with the first printing quality;
• controlling, in a case where the second printing quality is selected, a print executing unit to print the target image according to the target image data;
• setting, in a case where the second printing quality if selected, a scale factor for each of the plurality of objects, the scale factor being a ratio at which the each of the plurality of objects is reduced in size, a first scale factor indicating a ratio of a size of a reduced first object to the first object size, a second scale factor indicating a ratio of a size of a reduced second object to the second object size;
• generating, in a case where the second printing quality is selected, processed image data representing a processed image, the processed image including the size-reduced first object and the size-reduced second object;
• and
• controlling the print executing unit to print the processed image according to the processed image data.
