Disclosed is a data processing apparatus including an application execution unit that transmits job data; a print-request-source notification unit invoked by the application execution unit to report print-request-source information specifying a print request source; a virtual printer driver that is invoked upon receiving the job data, extracts job information specifying print settings from the job data, generates a work space for image conversion, and generates drawing data of a higher image format from the job data in the work space; and a transmission processing unit that is generated as a private instance for the job data, selects a printer driver corresponding to output-destination printer information associated with a client or a user of the client, instructs the selected printer driver to print the drawing data, and displays transmission destination information and/or print information determined for the job data on the print request source.
