Controlling ejection of ink drops with a less number of temperature sensors than the number of print heads. [Solution] The present invention is an printing apparatus for printing by ejecting ink drops onto a print medium. The printing apparatus comprises N print heads, M temperature sensors, and an ejection controller. M temperature sensors are allocated in the printing apparatus. An ejection controller is configured to control the ejection of he ink drops from at least part of the N print heads in response to an output of the M temperature sensors. The integer M is smaller than the integer N.
