Control device and storage medium

A non-transitory computer readable storage medium storing a program for controlling a printing execution unit including:

• a printing head including a plurality of nozzles configured to discharge ink;
• a head drive unit configured to cause the printing head to discharge the ink and to form dots on a printing medium;
• and a movement unit configured to move the printing medium relative to the printing head in a moving direction, the program, when executed by a computer of a control device, causing the control device to perform:
• acquiring target image data;
• specifying a character region indicative of a character in a print image based on the target image data, and a non-character object region indicative of an object different from the character in the print image;
• and
• causing the printing execution unit to print the print image by using the target image data, the print image being printed by alternately executing, for a plurality of times, (i) a partial printing in which dots are formed by the printing head and (ii) moving of the printing medium by the movement unit, and the plurality of times of the partial printings including a first partial printing and a second partial printing,
• wherein, in a case where a first condition including a condition that the non-character object region is located at an upstream end, in the moving direction, of a partial region which is configured to be printed by the first partial printing is met, the printing execution unit is caused to print the print image by:
• executing the first partial printing;
• moving the printing medium by a first movement amount after the first partial printing has been executed;
• and
• executing the second partial printing after the printing medium has been moved by the first movement amount, wherein dots are formed in a first overlap region by both the first partial printing and the second partial printing, the first overlap region including the upstream end of the partial region,
• wherein, in a case where a second condition including a condition that the character region is located at the upstream end of the partial region is met, the printing execution unit is caused to print the print image by:
• executing the first partial printing;
• moving the printing medium by a second movement amount greater than the first movement amount after the first partial printing has been executed;
• and
• executing the second partial printing after the printing medium has been moved by the second movement amount, wherein the dots are formed in the partial region by the first partial printing and the dots are not formed in the partial region by the second partial printing.
