This invention relates to a printing apparatus, printhead, and cartridge type discrimination method capable of achieving high-reliability, high-quality printing by effectively utilizing a memory element incorporated in the printing apparatus and dealing with an error by all the building components of the printing apparatus. According to this invention, in a printing apparatus which prints on a printing medium with an ink cartridge and inkjet printhead mounted on a carriage, mounting of the ink cartridge on the carriage is detected, identification information is read from the non-volatile memory of the ink cartridge, and it is discriminated on the basis of the identification information whether or not the mounted cartridge is a certified one for the printing apparatus.
