摘要： A printer apparatus performs notification of an execution instruction for second calibration to a print server based on a result of first calibration, stores time information on the notification, and transmits the time information to the print server in response to a request from the print server. The print server performs a warning to prompt a user to execute the second calibration when the execution instruction for the second calibration notified from the printer apparatus is received. The print server acquires the time information from the printer apparatus when the print server is started, and performs the warning when the time information indicates a date and time later than a date and time indicated by previously acquired time information that has been stored in the print server.
