This invention makes it possible to provide an image forming apparatus capable of causing an information processing apparatus to install a driver desired by a user by selecting an appropriate PDL and presenting device information to the information processing apparatus, and increasing the convenience for the user, a control method for the apparatus, and a program. To accomplish this, image forming unit-specific log information associated with a plurality of image forming units of the image forming apparatus is stored in a storage device. On the basis of the log information, a priority image forming unit is decided from the plurality of image forming units. Identification information containing an identifier of the decided image forming unit is transmitted in response to an information request transmitted from the information processing apparatus.
