A non-transitory computer readable storage medium storing a set of program instructions installed on and executed by a computer included in a label image generation device for generating a plurality of label images corresponding to respective ones of a plurality of labels, the plurality of label images being used for creating one or more composite labels, wherein in each of the one or more composite labels a label for a first layer created from a first printing medium and a label for a second layer created from a second printing medium are overlaid, the set of program instructions, when executed by the computer, causing the label image generation device to perform:
- a first generation process to generate a first label image for the first layer to be formed on the first printing medium;
- a second generation process to generate a second label image for the first layer to be formed on the first printing medium, the second label image being different from the first label image;
- a third generation process to generate a third label image for the second layer to be formed on the second printing medium;
- displaying a first composite image representing an image of a first composite label and a second composite image representing an image of a second composite label, wherein in the first composite image, the first label image and the third label image are overlaid, wherein in the second composite image, the second label image and the third label image are overlaid;
- and
- outputting a print instruction to a printing mechanism to print the first label image on the first printing medium for creating a first number of first labels for the first layer, to print the second label image on the first printing medium for creating a second number of second labels for the first layer, and to print the third label image on the second printing medium for creating a third number of third labels for the second layer, the third number being the sum of the first number and the second number, the print instruction including order information, the order information specifying an order of printing so that a combination of the first number of first labels and the second number of second labels is printed continuously.
