FIELD: printing equipment.
SUBSTANCE: invention relates to printing devices. Information processing device includes a receiving unit configured to obtain a measurement result, obtained by measuring the characteristic value of the print medium by the measurement unit, wherein the print medium is to be printed by the printing unit, a decision unit, configured to select a candidate for a print medium type based on a measurement result of the print medium obtained by the acquisition unit, a reference characteristic value of each of the types of print media, predetermined to identify type of measured print medium, input unit configured to input information associated with type of printing medium to be printed by printing unit, a determination unit configured to determine whether to vary the reference characteristic value of the type of the print medium associated with the input by the input unit, based on measurement result of printing medium and type of printing medium associated with information input by input unit, and change unit, made with possibility, when determination unit determines to change reference characteristic value of type of printing medium associated with information input by input unit, changing the reference characteristic value of the type of the printing medium associated with the information entered by the input unit based on the measurement result of the printing medium.
EFFECT: technical result is accurate identification of type of printing medium.
