Abstract: A roll sheet, in which a continuous sheet is wound in a roll form, is caused to rotate in a forward direction to supply the sheet to a printing unit. First and second sensors are arranged at positions facing an outer circumferential surface of the roll sheet and deviated in an axis line direction of the roll sheet. Outputs of the first and second sensors are changed in accordance with a distance to a sheet of the roll sheet. A rotation direction of the roll sheet is switched from a forward direction to a reverse direction on the basis of the outputs of the first and second sensors while the roll sheet is being rotated in the reverse direction.

Abstract: A printing method includes printing an image on a sheet with a printhead, detecting an edge of the printed image in a widthwise direction of the sheet, and performing borderless printing, based on the detection result, to make a margin amount in the widthwise direction become not more than a predetermined value so as to prevent the image from being formed outside of the sheet in the widthwise direction.

Abstract: A roll sheet with a continuous sheet wound in a roll form is rotated in a forward direction to supply the sheet to a printing unit. A sensor whose output is changed in accordance with a distance between the sensor and the sheet is used. A rotation direction of the roll sheet is switched from an opposite direction to the forward direction on the basis of the output of the sensor during rotation of the roll sheet in the opposite direction.

Abstract: Automatic sheet feeding of an installed roll is performed more reliably. To this end, a leading end of a sheet is detected on the basis of a change in an output value of a sensor while causing a roll to rotate in a winding direction using a sensor capable of detecting a distance to the sheet separated from the roll. After the detection, the roll is caused to rotate in a feeding direction, and a feeding state of the sheet is determined on the basis of a change in the output value of the sensor.

Abstract: A continuous sheet is conveyed in a first direction in a printing operation, cut with a cutter in a cutting operation, and then conveyed in a second direction opposite to the first direction. A conveyance amount of the continuous sheet in the second direction is changed based on an operation of the printing apparatus after the cutting operation.
