A non-transitory computer-readable storage medium stores computer-readable instructions for causing a terminal device to perform: generating first print data for creating a first print label having a first print object formed thereon; generating second print data for creating a second print label having a second print object formed thereon; generating, based on the first print data, outline data representing an outline of the first print object; generating, based on the outline data, alignment mark data representing an alignment mark used for aligning the first print label with the second print label when overlaying these labels; generating third print data by adding the alignment mark data to the second print data such that the alignment mark is added to a portion of the second print label that corresponds to the outline of the first print object; and transmitting the first and third print data to a label creating device.
