  • Publication number: 20200361203
    Abstract: An information processing apparatus includes a storage that stores a machine-learned model, an accepting section, and a processor. In the machine-learned model, according to a data set in which an association is made between discharge failure factor information related to the factor of a discharge failure and printed image information that represents an image formed on a print medium, a prediction condition has been machine-learned for the discharge failure. The accepting section accepts the discharge failure factor information from a printing apparatus. The processor predicts the discharge failure in the print head according to the accepted discharge failure factor information and the machine-learned model.
