In an information processing apparatus, which can communicate with a first output apparatus having a copying function of printing based on a scanned document image, and a second output apparatus having a print function of printing image data transmitted from an external device in a predetermined format, and has a server function of managing output jobs in the first and second output apparatuses, first output job information of a copy job to be executed by the first output apparatus is acquired. During execution of an output job, occurrence of any obstacle that disturbs execution of a job is detected. When it is detected that an obstacle has occurred during execution of the output job in the first output apparatus, the second output apparatus is controlled to execute a substitution print process based on the first output job information. In this way, a printer having only a print function can execute an output job of a copying machine or facsimile apparatus other than a print function.
