A non-transitory storage medium stores instructions executable by an information processing server communicable with a device capable of executing a print processing and a scan processing. A delivery address and a second surface image are to be printed on first and second surfaces of a delivery object. First feature information indicates a feature of the second surface image. The information processing server reads delivery address information and the first feature information associated with each other, when scan information is newly received. The information processing server extracts sample image information when the read delivery address information is the same as the delivery address information contained in the newly-received scan information. The sample image information is for displaying a sample image corresponding to the second surface image having a feature indicated by the first feature information associated with the read delivery address information.
