Abstract:
A printing apparatus for performing printing on a print medium with at least one mounted printhead having a plurality of print elements, comprising:a mounting portion in which the at least one printhead can be mounted; scanning means for reciprocally scanning the at least one printhead; detecting means for detecting a type and a number of printheads mounted; first determining means for determining a driving condition of the at least one printhead based on a result of detection by said detecting means; second determining means for determining a scanning speed of said scanning means based on the driving condition determined by said first determining means; a power supply, having a predetermined power capacity, for supplying electric power to drive the at least one printhead mounted in said mounting portion; and control means for controlling a print operation by driving the at least one printhead based on the driving condition determined by said first determining means, and by driving said scanning means based on the scanning speed determined by said second determining means, wherein the driving condition of the at least one printhead is determined based on the result of detection by said detecting means and the predetermined power capacity of said power supply.
