Printer

摘要

A label printer prints a QR code on print areas (labels) sequentially arranged along a sheet of paper while maintaining the QR code in a state in which its data can be restored. The label printer determines, in the course of separating the printed label and suspending and resuming movement of the paper and while printing on each label of the paper, whether or not both of two finder patterns aligned along one side of the QR code in a following print area are at a position to be printed when a boundary portion between a leading label that has been printed and the following label reaches a cut position. A print operation correcting control controls printing when both of two finder patterns aligned along one side of the QR code are in position to be printed, but not printed at the same time.

主权项

1. A printer for printing on print areas according to print data representing information to be printed, while sequentially moving a sheet of paper, along which the print areas are arranged at predetermined intervals, in a direction of an arrangement of the print areas, the printer comprising:
a print operation controller for controlling a print operation of the printer so as to stop movement of the paper to suspend printing on a print area and then to resume the movement of the paper and the printing on the print area; a determination device for determining if the print data includes data representing a QR code to be printed in a predetermined orientation with respect to the print areas, whether or not both of two finder patterns aligned along one side of the QR code in the print area for which the printing is suspended are at a position to be printed when movement of the paper is stopped; and a print operation correcting control configured for controlling the print operation, when the determination device has determined that both of the two finder patterns aligned along one side of the QR code in the print area for which the printing is suspended are at their positions to be printed when the movement of the paper is stopped, such that the two finder patterns of the QR code are not at respective positions to be printed at the same time.
