Printer, printer control method and program

A printer for printing on a label continuous body including a plurality of labels temporarily attached to a belt-like liner at predetermined intervals, comprising:

• a feeding unit configured to feed the label continuous body in a feeding direction or in an opposite direction of the feeding direction;
• a printing unit configured to print the label;
• a first detecting unit configured to identify a printing start position of the label, the first detecting unit being disposed at upstream side of the printing unit in the feeding direction of the label continuous body;
• a second detecting unit configured to detect an end portion of the label, the second detecting unit being disposed at downstream side of the printing unit in the feeding direction;
• and
• a controller configured to control printing by the printing unit and feeding of the label continuous body, wherein
• the controller calculates a label pitch from a downstream end portion and an upstream end portion of a first label detected by the second detecting unit, and if the label pitch is smaller than a distance from the first detecting unit to the printing unit, feeds the label continuous body to a printing start position of a second label in the opposite direction of the feeding direction based on the label pitch.

A control method for a printer with a printing unit configured to print a label of a label continuous body including a plurality of labels temporarily attached to a belt-like liner at predetermined intervals,

• a feeding unit configured to feed the label continuous body in a feeding direction or in an opposite direction of the feeding direction,
• a first detecting unit configured to identify a printing start position of the label, the first detecting unit being disposed at upstream side of the printing unit in the feeding direction of the label continuous body, and
• a second detecting unit configured to detect an end portion of the label, the second detecting unit being disposed at downstream side of the printing unit in the feeding direction, wherein
• calculating a label pitch from a downstream end portion and an upstream end portion of a first label detected by the second detecting unit,
• feeding the label continuous body to a printing start position of a second label in the opposite direction of the feeding direction based on the calculated label pitch if the label pitch is smaller than a distance from the first detecting unit to the printing unit.

A computer-readable storage medium storing a program for causing a computer installed in a printer with a printing unit configured to print a label of a label continuous body including a plurality of labels temporarily attached to a belt-like liner at predetermined intervals, to execute a process, comprising:

• a feeding unit configured to feed the label continuous body in a feeding direction or in an opposite direction of the feeding direction,
• a first detecting unit configured to identify a printing start position of the label, the first detecting unit being disposed at upstream side of the printing unit in the feeding direction of the label continuous body, and
• a second detecting unit configured to detect an end portion of the label, the second detecting unit being disposed at downstream side of the printing unit in the feeding direction,
• to function so as to:
• calculating a label pitch from a downstream end portion and an upstream end portion of a first label detected by the second detecting unit,
• feeding the label continuous body to a printing start position of a second label in the opposite direction of the feeding direction based on the calculated label pitch if the label pitch is smaller than a distance from the first detecting unit to the printing unit.
