This invention is directed at preventing unnecessary processing and CPU load of a PC when always printing via a printer driver, and avoiding the omission of a printer driver function when always performing direct printing. When using a printer having a direct printing function, which of printing via the printer driver and direct printing is to be done is determined in accordance with print settings of each print job, and then printing is executed. A function to be implemented by the driver among set functions is determined (S504). If there is a function to be implemented by the driver, it is determined whether to give priority to direct printing (S505). If no priority is given to direct printing, the driver is used; otherwise, direct printing is performed.
