Patent ID: 7145668

Claim:
A print system in which a printing apparatus prints by using print data which is sent by a printer driver which is made operative by an information processing apparatus, wherein said printer driver comprises: a structure information generation unit adapted to divide each page of print data to be sent into a plurality of data blocks and to generate structure information of each data block, the structure information including a color attribute of the data block; an information adding unit adapted to add the structure information generated by said structure information generation unit to each data block of the print data which is sent; and an information sending unit adapted to send the print data including the added structure information to said printing apparatus, wherein said printing apparatus comprises: a determination unit adapted to determine a number of nozzles of a print head to be used for each data block of the print data on the basis of the received structure information; and a print process unit adapted to execute a printing process of the data block of the print data by using the number of nozzles determined by said determination unit, wherein if data of a next page exists, during the print of a present page, said printer driver notifies said printing apparatus of a print mode and a data structure of the next page as said structure information by said information sending unit, and wherein if it is possible to confirm that a printing operation which is being performed at present can be continuously executed from said notified contents, said printing apparatus subsequently executes a process of the next page.
