A system, a control apparatus, a control method and a computer program are provided which are configured to control a printing output in response to characteristics of a printing apparatus when a plurality of printing apparatuses has different characteristics. A host computer acquires apparatus information including characteristics information indicating the characteristics of a printer and thereby determines a priority order of printers in relation to the print data based on the characteristics information. The host computer then determines a printer to output the print data based on the determined priority order and outputs the print data to the determined printer.
