A printer that receives requests to print on plural different media enables efficient system maintenance and system changes. A printer connected in a daisy chain to a host device or a first printer on one side and to a second printer on the other side has a communication unit that receives print request data from the host device or the first printer, and sends the print request data to the second printer; a print unit that interprets the received print request data and executes a printing control process based on the result of data interpretation; and a response unit that generates individual response data for the printer based on the result of the printing control process, generates unified response data from response data received from the second printer and the individual response data, and sends the unified response data to the host device or the first printer.
