This printer performs printing on a print medium having an RFID, and comprises: a communication unit which has a communication part movably provided in a predetermined area along the transport surface of the print medium, and communicates with an IC chip of the RFID; and a detection unit which detects the print medium by means of detection light. The detection unit includes: a light emitting part that emits detection light; a light guide member that guides the detection light emitted from the light emitting part to the print medium; and a light receiving part that receives the detection light via the print medium.

A printer that allows selection of a plurality of types of print media includes, a control unit that stores a plurality of pieces of registration information, the registration information including one set of a plurality of printing setting items used for printing, the plurality of printing setting items include an item regarding the type of the print medium.

The controller executes the first process once and then executes the second process. The first process is a process for back-feeding the continuous body, writing information to the RFID inlet, and then forward-feeding the continuous body until the RFID medium reaches the print start position. The second process is a process for stopping printing on the RFID medium halfway and writing information to the subsequent RFID medium following the RFID medium under printing when the RFID inlet of the subsequent RFID medium reaches the position allowing the communication with the antenna, and then resuming and completing printing on the RFID medium, printing on which was stopped halfway.

A product sales data processing system includes: a sensor attached to a bulk food container of a product; and a weighing apparatus. The sensor includes: a sensor module that detects displacement of the sensor; a memory that stores a sensor ID that identifies the sensor; and a transmitter that transmits the sensor ID stored in the memory when the sensor module detects a predetermined displacement value. The weighing apparatus includes: a receiver that receives the sensor ID transmitted from the sensor; and a display that displays product information associated with the sensor ID.

The present invention relates to a medicinal product sales management method, a medicinal product sales management system, a computer program therefor, and a medicinal product information sheet. According to an aspect of the present invention, when a medicinal product, for which an order is placed by a pharmacy to a distributor, is delivered to the pharmacy and the inventory is managed, a single medicinal product information sheet, in which medicinal product price information printed in numbers, medicinal product management information printed in an optical code, and medicinal product management information encoded in a radio frequency identification (RFID) tag have been integrated, is used.
