Claim Text:
1. A control device comprises: a processor; and a memory storing computer-readable instructions therein, the computer-readable instructions, when executed by the processor, causing the control device to perform: acquiring image data representing a target image; creating print data by using the image data; and supplying the print data to a print performing unit, wherein the print performing unit comprises a print head configured to perform a main scanning operation of discharging ink while moving along a main scanning direction, the print head comprises K groups of nozzles (K being an integer equal to or more than 2) provided along a sub scanning direction being orthogonal to the main scanning direction, in the K groups of nozzles, a first type of nozzle group and a second type of nozzle group are alternately provided along the sub scanning direction, the first type of nozzle group comprising a first type of nozzle line including N pieces of nozzles (N being an integer equal to or more than 2) provided along the main scanning direction, the second type of nozzle group comprising a second type of nozzle line including N pieces of nozzles provided along the main scanning direction, a color of ink discharged by an n-th nozzle (n being each integer satisfying 1≦n<N) from a first side of the main scanning direction among the N pieces of nozzles included in the first type of nozzle line is identical to a color of ink discharged by an n-th nozzle from a second side of the main scanning direction among the N pieces of nozzles included in the second type of nozzle line, the creating of the print data includes selecting one printing method for printing the target image on a record medium from among a plurality of printing methods including a first printing method and a second printing method, the first printing method being a printing method for performing a color printing of the target image by the print head conducting both of a first main scanning operation and a second main scanning operation, the first main scanning operation including discharging ink while moving from the first side to the second side in the main scanning direction, the second main scanning operation including discharging ink while moving from the second side to the first side in the main scanning direction, the second printing method being a printing method for performing a color printing of the target image by the print head conducting only a specific main scanning operation which is one of the first main scanning operation and the second main scanning operation, and the creating of the print data includes:
