CONSTITUTION: A printing device(100) for an electronic element having a bidirectional printing function comprises first and second winding rollers(110,120), a printing unit(130), a drying unit(140), an idler(150), and a doctoring device. The first and second winding rollers are used as a winder or an unwinder. The printing unit comprises a pressing roller(131) and a printing roller(132). The pressing roller presses an object(1) to the printing roller. The printing roller prints the object. The drying unit dries the object passing through the printing unit. The idler is detachably arranged inside the drying unit and has first and second idlers(151,152) arranged on the front and rear of the printing unit. The doctoring device has first and second doctoring devices(D1,D2) arranged on the left and right of the printing roller.
