Abstract: A printing abnormality detection system includes a printer that prints an image on a printing medium based on image data, a reader that reads the image printed on the printing medium, a processing unit that detects an abnormal printed portion based on read image data from the reader, a storage unit that stores information of a display necessity determination criterion, and a display unit. The processing unit determines, based on the image data, the read image data, and the display necessity determination criterion, whether the abnormal printed portion is to be displayed on the display unit. When the processing unit determines that the abnormal printed portion is to be displayed, the processing unit executes a process of displaying, on the display unit, abnormal printed portion information including an image of the abnormal printed portion.
