Abstract:
1. A label printer, comprising: a conveying mechanism that conveys label paper, in which a plurality of labels including an RFID tag adhere to a long-length mount with a predetermined pitch along a longitudinal direction of the mount, along a conveying route; a printing unit that carries out printing with respect to the labels on the conveying route; an RFID reader and writer which is provided upstream of the conveying route in relation to the printing unit, and which carries out reading-in and writing-in of information with respect to the RFID tag included in each of the labels; a communication intensity information acquisition unit that acquires information indicating a communication intensity between each of a plurality of the RFID tags and the RFID reader and writer in correlation with identification information of each of the RFID tags, if communication with the plurality of the RFID tags occurs simultaneously in the RFID reader and writer while conveying the mount by the conveying mechanism along the conveying route; a maximum communication intensity position determination unit that determines a maximum communication intensity position, at which a communication intensity capable of being correlated with the identification information of each of the RFID tags becomes the maximum, on the basis of a tendency of a variation in the communication intensity of each of the plurality of RFID tags which accompanies the conveyance along the conveying route, the communication intensity being acquired by the communication intensity information acquisition unit, and a conveying distance of the mount by the conveying mechanism; and an optimal communication position calculation unit that calculates an optimal communication position with the RFID tags of the plurality of labels adhered to the label paper on the basis of the maximum communication intensity position determined by the maximum communication intensity position determination unit with respect to each of the plurality of RFID tags.
