A recording system for relatively easily and rapidly performing a registration adjustment in a recording device having a plurality of recording units which record divided recording images on the same recording medium. The recording system causes each of recording units (A-F) to record a registration adjustment pattern. Based on the recorded pattern, an inter-unit adjustment that is a registration adjustment among the plurality of recording units and an intra-unit adjustment that is a registration adjustment among the plurality of recording heads in each recording unit are performed.

Registration adjustment value determination method, recording system, and registration adjustment method

This invention provides a printing apparatus and an information processing apparatus which can process precise information on the number of pixels printed by nozzles of the print head without degrading throughput and properly manage the service life of the print head. To this end, a plurality of nozzles of the print head are divided into a plurality of blocks and a nozzle in each of the blocks which prints a maximum number of pixels in a predetermined unit print volume is taken to be a representative nozzle. In each of the blocks, the numbers of pixels printed by the representative nozzle for every unit print volume are accumulated and managed.
