A print system in which when a print driver can previously confirm data structure information during data generation, printing efficiency can be raised by using the structure information is provided. While the printer driver which is made operative by a host computer is generating print data, if the structure information of the print data can be confirmed, prior to sending the print data, structure information of the data is sent to a printer. For example, when the printer is notified of structure information showing that color/monochrome data continues for a predetermined number of rasters in the first block of the print data by a host computer, the printer selects the optimum printing method on the basis of the structure information without analyzing the print data.
