Printing system and adjustment supporting method

An adjustment supporting method for supporting adjustment of a value of a print parameter in a printing apparatus provided with a conveyance mechanism configured to convey a print medium, a conveyance controller configured to control a conveyance speed at which the conveyance mechanism conveys the print medium, a printing unit configured to perform printing by ejecting ink onto the print medium being conveyed by the conveyance mechanism, a drying mechanism configured to dry the print medium after printing by the printing unit, and a drying controller configured to control a drying temperature at which the drying mechanism dries the print medium, the adjustment supporting method comprising:

• a printing condition input step of inputting, by an operator, a printing condition;
• and
• a recommended value output step of outputting, by a computer, a plurality of recommended values for at least one of a conveyance speed and a drying temperature as a print parameter on a basis of an input printing condition that is a printing condition inputted in the printing condition input step,
• wherein the recommended value output step includes
• a recommended candidate value search step of obtaining a plurality of recommended candidate values that are candidates for the plurality of recommended values on a basis of the input printing condition, using a recommended candidate value search model learned by machine learning, and
• a recommended candidate value evaluation step of selecting output targets as the plurality of recommended values from the plurality of recommended candidate values by evaluating each of the plurality of recommended candidate values.
