To improve printing quality when printing an image on a body to be printed using an articulated robot.SOLUTION: A printer 10 performs printing while changing a relative position between a base material 20 and a print head 102 using an articulated robot 104. The printer includes a plurality of encoders 50 which measure movement amount along each movable shaft for each movable shaft of the articulated robot 104. In a chip 122 for distance calculation, a moving distance in a three-dimensional space of a work point of the articulated robot 104 is calculated on the basis of the movement amount measured by the encoders 50, and a pulse signal according to the moving distance is output. A print head driver 124 controls a printing operation by the print head 102 using the pulse signal together with shape information on a printing figure and printing position information.SELECTED DRAWING: Figure 7 【課題】多関節ロボットを用いて被印刷体に画像を印刷する際の印刷品質を向上させること。【解決手段】印刷装置１０は、多関節ロボット１０４を用いて基材２０とプリントヘッド１０２との相対位置を変化させながら印刷を行う。多関節ロボット１０４の移動軸毎には、それぞれの移動軸に沿った移動量を測定する複数のエンコーダ５０が設けられている。距離算出用チップ１２２では、エンコーダ５０で測定された移動量に基づいて、多関節ロボット１０４の作業点の３次元空間上の移動距離を算出し、移動距離に応じたパルス信号を出力する。プリントヘッドドライバ１２４は、印刷図形の形状情報や印刷位置情報とともに、パルス信号を用いてプリントヘッド１０２による印刷動作を制御する。【選択図】図７
