1. A printing apparatus, comprising:
a feeding unit configured to feed a printing medium wound in a roll form;
a conveyance roller configured to convey, in a conveyance direction, the printing medium fed from the feeding unit;
a printing unit configured to apply a liquid to adhere to the conveyed printing medium to perform printing;
a guide unit configured to come into contact with the printing medium to apply a tensile force;
a winding unit configured to wind the printing medium after printing; and
a control unit, wherein
the feeding unit, the conveyance roller, the printing unit, the guide unit, and the winding unit are disposed in this order from upstream in the conveyance direction,
the guide unit includes a first heater configured to heat a guide surface being a surface that comes into contact with the printing medium, and applies the tensile force to the printing medium after the printing while heating the printing medium through the guide surface by the first heater,
the control unit controls a winding force of the winding unit to adjust the tensile force applied to the printing medium by the guide unit,
the control unit controls the winding unit and the first heater to change the winding force of the winding unit and a heating temperature of the first heater in accordance with a type of the printing medium, a printing condition during printing, or an environmental condition,
when a receptive amount of a receptive layer of the printing medium is a predetermined receptive amount, the control unit sets the heating temperature of the first heater to a first heating temperature, and sets the tensile force applied by the guide unit to a first tensile force,
when the receptive amount of the receptive layer of the printing medium is greater than the predetermined receptive amount, the control unit makes the heating temperature lower than the first heating temperature, and makes the tensile force lower than the first tensile force, and
when the receptive amount of the receptive layer of the printing medium is smaller than the predetermined receptive amount, the control unit makes the heating temperature higher than the first heating temperature, and makes the tensile force greater than the first tensile force.
