<p>PROBLEM TO BE SOLVED: To solve the problem that, when a linear velocity on a roll body side is made faster, a difference in transportation linear velocity between both becomes too large and causes increase of drive load and deviation between a transportation part and a print medium.SOLUTION: In control of pullback operation, a speed difference between a rotational direction linear speed of a roll body 4 and a rotational direction linear speed of a transportation rotating body (transportation roller 22) is assumed as Va, until a peeling position of a print medium 2 from a roll body 4 is before the transportation roller 22 and becomes a tangent direction of the roll body 4, for transportation, and when it is the tangent direction, control is made for switching so that a speed difference between the rotational direction linear speed of the roll body 4 and that of the transportation rotating body (transportation roller 22) becomes Vb (Va>Vb).</p> |
