When a first device is connected as an external device, the control section transmits, to the first device, information indicating that the POS peripheral device operates as a communication device. When a second device is connected as the external device, the control section transmits, to the second device, information indicating that the POS peripheral device operates as a storage that stores information in the storing section. ## Claims ### Claim 1 A POS peripheral device comprising: a storing section configured to store setting information; and a control section configured to control the storing section, wherein when a first device is connected as an external device, the control section transmits, to the first device, information indicating that the POS peripheral device operates as a communication device and, when a second device is connected as the external device, the control section transmits, to the second device, information indicating that the POS peripheral device operates as a storage that stores information in the storing section. ### Claim 2 (depends on 1) The POS peripheral device according to claim 1, further comprising a display section configured to display an image indicated by image information, wherein when the first device is connected as the external device, after transmitting, to the first device, the information indicating that the POS peripheral device operates as the communication device, when receiving first image information indicating a first image from the first device, the control section causes the display section to display the first image. ### Claim 3 (depends on 2) The POS peripheral device according to claim 2, wherein the setting information includes image information indicating an image that the control section can cause the display section to display. ### Claim 4 (depends on 2) The POS peripheral device according to claim 2, wherein the first image information is information received by the first device from an information processing device connected to the first device. ### Claim 5 (depends on 1) The POS peripheral device according to claim 1, wherein, when the second device is connected as the external device, after transmitting, to the second device, the information indicating that the POS peripheral device operates as the storage, when receiving the setting information from the second device, the control section causes the storing section to store the setting information received from the second device. ### Claim 6 (depends on 1) The POS peripheral device according to claim 1, wherein, when the POS peripheral device is connected to the external device, the control section determines whether communication with the external device is communication in a first mode or communication in a second mode different from the first mode and, when determining that the communication with the external device is the communication in the first mode, determines that the first device is connected as the external device and transmits, to the first device, the information indicating that the POS peripheral device operates as the communication device and, when determining that the communication with the external device is the communication in the second mode, determines that the second device is connected as the external device and transmits, to the second device, the information indicating that the POS peripheral device operates as the storage. ### Claim 7 (depends on 6) The POS peripheral device according to claim 6, wherein, when the POS peripheral device is connected to the external device, the control section starts to operate as the communication device and, thereafter, determines whether the communication with the external device is the communication in the first mode or the communication in the second mode. ### Claim 8 (depends on 7) The POS peripheral device according to claim 7, wherein, when the POS peripheral device is connected to the external device, the control section starts to operate as the communication device and, thereafter, determines whether the communication with the external device is the communication in the first mode or the communication in the second mode and, when determining that the communication with the external device is the communication in the second mode, determines that the second device is connected as the external device, blocks the communication with the second device, stops operating as the communication device, and then starts to operate as the storage and resumes the communication with the second device. ### Claim 9 (depends on 1) The POS peripheral device according to claim 1, wherein the POS peripheral device is a customer display. ### Claim 10 (depends on 1) The POS peripheral device according to claim 1, wherein the first device is a printing device, and the second device is an information processing device. ### Claim 11 A control method for a POS peripheral device including a storing section configured to store setting information, the control method comprising: when a first device is connected as an external device, transmitting, to the first device, information indicating that the POS peripheral device operates as a communication device; and when a second device is connected as the external device, transmitting, to the second device, information indicating that the POS peripheral device operates as a storage that stores information in the storing section.
