  • Publication number: 20240092606
    Abstract: A device for generating processing job includes a processor and a non-transitory storage medium that stores a program for the processor to generate the processing job. The processor searches for at least one candidate for the cutting position based on layout information that is information regarding a position of the product disposed on the sheet. From among the at least one candidate for the cutting position, the processor selects a candidate that has a small number of cutting positions based on a maximum size of a first margin region between a contour of the sheet and a contour of the product in the first direction, and, a maximum size and a minimum size of the intermediate sheet in the first direction. The processor generates a processing job for performing processing at the selected cutting position.
