A verification system includes a printer which prints image on a recording sheet, a reader which reads an image printed on the recording sheet, and controllers to set a first print setting via a setting screen, cause the printer to print an image based on the set first print setting, cause the reader to read the printed image, and register the read image as a correct image. The controllers also set a second print setting via the setting screen, cause the printer to print an verification target image based on the set second print setting, cause the reader to read the printed verification target image, and verify the read image using the registered correct image, and control the setting screen for the second print setting so that a predetermined print setting included in the first print setting cannot be edited on the setting screen for the second print setting.
