Printer, printer control method, and program

A printer for printing on a label continuous body in which labels are releasably attached to a long liner sheet at a predetermined spacing, the printer comprising:

• a conveyance unit configured to convey the label continuous body;
• a printing unit configured to print on each of the labels;
• a first detection unit disposed upstream of the printing unit in a conveyance direction and configured to detect each of the labels;
• a second detection unit disposed downstream of the printing unit in the conveyance direction and configured to detect each of the labels;
• and
• a controller configured to control the printing on the label and the conveyance of the label continuous body based on detection results of the first detection unit and the second detection unit, wherein:
• the controller is configured to:
• perform the printing on the label by the printing unit while conveying the label continuous body, and measure, by the second detection unit, an arrangement length which is a spacing between a downstream end portion of the label on which the printing is performed and a downstream end portion of the label adjacent to the label on which the printing is performed,
• set a reference print start position of the label upstream of the printing unit based on the arrangement length, and
• correct the reference print start position using the arrangement length and an inter-unit distance between the printing unit and the first detection unit.

A printer control method for controlling a printer that comprises a printing unit configured to print on a label continuous body in which labels are releasably attached to a long liner sheet at a predetermined spacing, a conveyance unit configured to convey the label continuous body, a first detection unit disposed upstream of the printing unit in a conveyance direction and configured to detect each of the labels, and a second detection unit disposed downstream of the printing unit in the conveyance direction and configured to detect each of the labels, the printer control method being for controlling the printing on the label and the conveyance of the label continuous body based on detection results of the first detection unit and the second detection unit, the printer control method comprising:

• performing the printing on the label by the printing unit while conveying the label continuous body, and measuring, by the second detection unit, an arrangement length which is an spacing between a downstream end portion of the label on which the printing is performed and a downstream end portion of the label adjacent to the label on which the printing is performed;
• setting a reference print start position of the label upstream of the printing unit based on the arrangement length;
• and
• correcting the reference print start position using the arrangement length and an inter-unit distance between the printing unit and the first detection unit.

A non-transitory computer-readable recording medium including a program configured to cause a computer of a printer that comprises a printing unit configured to print on a label continuous body in which labels are releasably attached to a long liner sheet at a predetermined spacing, a conveyance unit configured to convey the label continuous body,

• a first detection unit disposed upstream of the printing unit in a conveyance direction and configured to detect each of the labels, and a second detection unit disposed downstream of the printing unit in the conveyance direction and configured to detect each of the labels, the program being for controlling the printing on the label and the conveyance of the label continuous body based on detection results of the first detection unit and the second detection unit, the program causing the computer to:
• perform the printing on the label by the printing unit while conveying the label continuous body, and measure, by the second detection unit, an arrangement length which is an spacing between a downstream end portion of the label on which the printing is performed and a downstream end portion of the label adjacent to the label on which the printing is performed;
• set a reference print start position of the label upstream of the printing unit based on the arrangement length;
• and
• correct the reference print start position using the arrangement length and an inter-unit distance between the printing unit and the first detection unit.
