A non-transitory computer-readable storage medium stores computer-readable instructions executable by a processor of an information processing device. The instructions support a general-purpose printing program incorporated in an operating system of the information processing device. The instructions, when executed by the processor, cause the information processing device to obtain, from a printer, main body information about sheet characteristics for each feed tray of the printer, obtain print settings from the general-purpose printing program, generate, based on the main body information, notification data including sheet information indicating the sheet characteristics for a feed tray set in the print settings, and provide the notification data to the general-purpose printing program, thereby enabling the notification data to be displayed on the print setting screen.
