Abstract
A printer includes a platen roller conveying a label sheet, a first motor rotating the roller, a print head facing the roller and printing on a label of the sheet, a discharge port, a winding roller for winding the sheet from which the label has been detached, a second motor rotating the winding roller, a drive train by which a rotational force can be transmitted from the second motor to the winding roller, and a processor controlling the motors to rotate in a first direction to convey the sheet in a forward direction and controlling the head to print on a first label of the sheet, and after the label is discharged, controlling the motors to rotate in a second direction opposite to the first direction. The drive train disengages the winding roller from the second motor when the second motor is controlled to rotate in the second direction.
Claims18
A printer for printing on a label sheet including a plurality of detachable labels, comprising:
- a platen roller configured to convey the label sheet;
- a first motor connected to the platen roller to rotate the platen roller;
- a print head facing the platen roller and configured to print on a label of the label sheet;
- a discharge port through which the printed label is discharged and detached;
- a winding roller for winding the label sheet from which the printed label has been detached;
- a second motor;
- a drive train by which a rotational force can be transmitted from the second motor to the winding roller;
- and
- a processor configured to:
- control the first and second motors to rotate in a first direction to convey the label sheet in a forward direction along a conveyance path and control the print head to print on a first label of the label sheet, and
- after the printed first label is discharged, control the second motor to rotate in a second direction that is opposite to the first direction while the first motor is controlled to rotate in the first direction, and then control the first motor and the second motor to rotate in the second direction, wherein
- the drive train disengages the winding roller from the second motor when the second motor is controlled to rotate in the second direction.
A method carried out by a printer that includes:
- a platen roller configured to convey a label sheet,
- a first motor connected to the platen roller to rotate the platen roller,
- a print head facing the platen roller and configured to print on a label of the label sheet,
- a discharge port through which the printed label is discharged and detached,
- a winding roller for winding the label sheet from which the printed label has been detached,
- a second motor, and
- a drive train by which a rotational force can be transmitted from the second motor to the winding roller, the method comprising:
- controlling the first and second motors to rotate in a first direction to convey the label sheet in a forward direction along a conveyance path and controlling the print head to print on a first label of the label sheet;
- discharging the printed first label through the discharge port;
- and
- controlling the second motor to rotate in a second direction that is opposite to the first direction while the first motor is controlled to rotate in the first direction, and then controlling the first motor and the second motor to rotate in the second direction, wherein
- the drive train disengages the winding roller from the second motor when the second motor is controlled to rotate in the second direction.
