1. A setting device for a print engine including a print head provided with a plurality of head unit including a first head unit provided with N1 first nozzles, N1 being an integer of 4 or more, located at positions different from each other in a specific direction and a second head unit provided with N2 second nozzles, N2 being an integer of 4 or more, located at positions different from each other in the specific direction, wherein:
the first head unit and the second head unit are located at positions different from each other in an intersecting direction intersecting with the specific direction,
a first range includes a first overlapping range and a first non-overlapping range,
the first overlapping range overlaps with a second range in the specific direction,
the first non-overlapping range does not overlap with the second range in the specific direction,
the N1 first nozzles are located in the first range,
the N2 second nozzles are located in the second range,
the N1 first nozzles and the N2 second nozzles are nozzles that eject ink of the same color,
the N1 first nozzles include two or more nozzle groups being at positions different from each other in the intersecting direction, and
the N2 second nozzles include two or more nozzle groups being at positions different from each other in the intersecting direction,
wherein the setting device is configured to:
cause the print engine to print a specific image, the specific image including a first image to be printed using at least some of the N1 first nozzles and a second image to be printed using at least some of the N2 second nozzles;
receive relative position information determined based on the printed specific image, the relative position information including information indicating a positional deviation amount in the specific direction between the N1 first nozzles and the N2 second nozzles; and
set, based on the relative position information, use nozzles to be used for printing and non-use nozzles not to be used for printing among the first nozzles and the second nozzles within the first overlapping range.
