Printer

A printer comprising:

• a conveying unit including a platen roller extending in a first direction across a conveying path of a medium to be printed with an image to convey the medium to be printed in a second direction orthogonal to the first direction through the conveying path;
• a printing unit extending in the first direction opposite to the platen roller with the conveying path interposed therebetween to print an image on the medium to be printed conveyed through the conveying path;
• a pressing unit including a plurality of pressing members which press the printing unit in a third direction toward the platen roller at a plurality of positions in the first direction;
• a supporting unit which supports proximal ends of the pressing members movably in the first direction in accordance with a width of the medium to be printed along the first direction;
• and
• a setting unit which sets a distance from the supporting unit to a plurality of pressure-receiving surfaces of the printing unit such that a pressing force applied to the medium to be printed by the platen roller and the printing unit is uniformed along the first direction and a pressing force per unit length along the first direction is made constant regardless of the width of the medium to be printed in a state that the pressure-receiving surfaces of the printing unit are provided along the first direction and allowed to be pressed in the third direction by distal ends of the pressing members whose proximal ends are supported by the supporting unit, and the pressing members are moved in the first direction in accordance with the width of the medium to be printed.
