A control device may create and supply print data. The print data may include first edge print data and first central print data. The first edge print data may include data for causing a print performing unit to perform printing which satisfies: a print medium is transported along a first direction by a first transportation amount; a first type of main-scanning action is performed; a number of nozzles of a usage nozzle group is maintained to n; and the usage nozzle group is shifted toward an upstream side along the first direction. The first central print data may include data for causing the print performing unit to perform printing which satisfies: the print medium is transported along the first direction by a second transportation amount; a second type of main-scanning action is performed; and the number of nozzles of the usage nozzle group is maintained to n.
