A mechanism in which whether or not a printing process can be executed in a user's desired format can be recognized by the user before a print output is executed from an application is provided. The application inquires of a printer driver about a restriction value of a printing apparatus in the case of executing the printing process by print setting designated by the user and obtains such a value. Whether or not the printing process can be executed is discriminated on the basis of the obtained print restriction value information and the number of pages of a print document. If it is determined that the printing process cannot be executed, a message showing that it is impossible to execute the printing process is displayed onto a displaying apparatus. If the printing process cannot be executed, the user is allowed to select available print settings.
