A printer includes a printing mechanism, a printer BLT communicator, a printer device communicator capable of communicating with a customer display, and a printer processor for performing printing based on print data in a case where the print data is received and transmits display data to the customer display in a case where the display data is received, in which the printer processor temporarily stops wireless communication by shifting an operation mode of the printer BLT communicator to a Sniff mode to transmit a communication request to the POS terminal device at a communication request interval in a case where a period during which the print data or the display data is not received exceeds a shift period, and changes the communication request interval depending on whether or not the customer display is connected.
