A printing apparatus includes a printing head; an airflow generating unit; a first flow path that includes a one-side end coupled to the airflow generating unit and an another-side end coupled to a first discharge port and through which the airflow passes; and a peeling unit configured to partially peel the label from the base sheet. When, the label partially peeled from the base sheet by the peeling unit, at least a portion of a peeled portion peeled from the base sheet is at a position not overlapping with the peeling unit in plan view and a non-peeled portion not peeled from the base sheet is in a state of overlapping with the peeling unit in plan view, the first discharge port is disposed at such a position that the airflow outputted from the first discharge port hits the back surface of the peeled portion.

Printing apparatus

A cleaning roller to be brought into contact with a medium includes a rotary shaft having a first end portion and a second end portion, and a sticky roller attached to the rotary shaft. A cleaning roller holder includes a first bearing portion configured to restrict a movement range of the first end portion and a second bearing portion configured to restrict a movement range of the second end portion. In a state where the first end portion is disposed at the first bearing portion and the second end portion is disposed at the second bearing portion, the cleaning roller holder positions the cleaning roller in a detachable manner. The center of gravity of the cleaning roller is shifted from the center of the cleaning roller in the longitudinal direction toward the first end portion, and is in a range where the sticky roller exists in the longitudinal direction.

Foreign material removing device and printing apparatus

A printer for printing on rolled paper includes an air pressure sensor that detects air pressure, a platen that has a suction hole and is installed on a transport path of the rolled paper, a suction fan that sucks the rolled paper via the suction hole, and a control section that performs control for changing a rotation speed of the suction fan according to a detection result of the air pressure sensor.

Printing apparatus and control method therefor

A printing apparatus includes a transport roller configured to transport a print medium in a transport direction, a print head configured to print on the print medium, a platen having first suction arrays each including at least a first suction hole having a first diameter and second suction arrays each including at least a second suction hole having a second diameter that is different from the first diameter, the first suction arrays and the second suction arrays being alternately arranged in a direction intersecting the transport direction, a suction fan configured to suck the print medium through frame portions each having one first suction array and one second suction array, and a shutter mechanism configured to open or close the frame portions stepwise.

Roll paper for printing maintains high bending resistance at the perforations without impairing the ease of separation at the perforation. The paper has perforationsA,A formed across the width of the paper at a specific interval lengthwise, and the perforationA,A have either a sawtooth shape or a wave shape. The roll paper also has a liner, and a plurality of labelsaffixed by adhesiveat an even interval along the length of the liner. The perforationA,A are formed in the linerbetween two adjacent labels
