Image data transfer control device and image data transfer control method

An image data transfer control method comprising:

• acquiring image data transferred in predetermined units;
• selecting each divided image line group of a plurality of divided line groups including a predetermined number of divided image lines based on inclination correction data corresponding to an inclination of a print head configured to print an image based on the image data comprising a plurality of divided image lines;
• specifying first correction target image data included in a first divided image line group of the plurality of divided line groups and second correction target image data included in a second divided image line group of the plurality of divided line groups, based on correction position data indicating a correction position included in at least one divided image line among the predetermined number of divided image lines comprising each divided image line group;
• storing the first correction target image data corresponding to a data transfer of the first divided image line group;
• outputting the first correction target image data corresponding to the data transfer of the second divided image line group, and storing the second correction target image data;
• and
• outputting, to the print head, the second divided image line group including the first correction target image data output instead of the second correction target image data.

A non-transitory computer-readable medium configured to store instructions thereon, which instructions, when executed by a processor, cause a controller to perform operations comprising:

• acquiring image data transferred in predetermined units;
• selecting each divided image line group of a plurality of divided line groups including a predetermined number of divided image lines based on inclination correction data corresponding to an inclination of a print head configured to print an image based on the image data comprising a plurality of divided image lines;
• specifying first correction target image data included in a first divided image line group of the plurality of divided line groups and second correction target image data included in a second divided image line group of the plurality of divided line groups, based on correction position data indicating a correction position included in at least one divided image line among the predetermined number of divided image lines comprising each divided image line group;
• storing the first correction target image data corresponding to a data transfer of the first divided image line group;
• outputting the first correction target image data corresponding to the data transfer of the second divided image line group, and storing the second correction target image data;
• and
• outputting, to the print head, the second divided image line group including the first correction target image data output instead of the second correction target image data.
