NON-TRANSITORY COMPUTER-READABLE STORAGE MEDIUM STORING INSTRUCTIONS REALIZING SUPPORTING PROGRAM

原文（中国語）

A supporting program for a printer supports multiple sheet sizes. The supporting program, when executed by a controller of an information processing device, causes the information processing device to, in response to receiving a request from a universal printing program, obtain sheet size data representing a sheet size list including a first-type sheet size, and generate document size data including available document sizes including the first-type sheet size and a second-type sheet size. When the universal printing program receives a print instruction from an application program, the supporting program causes the information processing device to determine whether a document size of an image to be printed is included in the first-type sheet size; when the document size is not included in the first-type sheet size, scale the image to fit the first-type sheet size; and cause the printer to print the image to be printed or a scaled image.
