Zusammenfassung:	To suppress impact in an ink discharge direction because of heat transfer inside a head due to ink.SOLUTION: A temperature condition of a liquid discharge head is detected while ink circulation means performs ink circulation so that a discharge head reaches a predetermined temperature, thereby pressure control means adjusts pressure and an ink circulation amount per time is controlled.SELECTED DRAWING: Figure 10 【課題】インクによるヘッド内の熱の移動によるインクの吐出方向への影響を抑える。【解決手段】インク循環手段によりインク循環を行いつつ液体吐出ヘッドの温度状態の検知を行い、吐出ヘッドが所定の温度に達するように、圧力制御手段の圧力調整を行い時間当たりのインクの循環量の制御を行う。【選択図】図１０
