A printing apparatus and print control apparatus acquire apparatus information required to specify each other's apparatuses by exchanging them. An information processing apparatus determines with reference to a database which stores data to be set in a printer driver and information indicating acquisition source of the data in association with each other whether data to be set in the printer driver is acquired from the printing apparatus or print control apparatus. The information processing apparatus acquires data from the determined printing apparatus or print control apparatus and causes the acquired data to be reflected in the settings of the printer driver.
