This is because a malicious third party can connect his terminal and the printing apparatus 10 to occupy the printing apparatus 10 or cause the printing apparatus 10 to print unexpected information. is there.
If an external device that is not permitted to communicate is prevented from being paired, the external device cannot be wirelessly connected to the printing apparatus 10, and the printing apparatus 10 can be prevented from being used maliciously by a third party.
Based on the above, the printing apparatus 10 according to the present embodiment executes the following processing regarding pairing.

FIG. 3 is a flowchart showing the operation of the printing apparatus 10.
At the start of the flowchart of FIG. 3, the printing apparatus 10 is not wirelessly connected to the control apparatus 11, and any external apparatus can make a pairing request to the printing apparatus 10.

As shown in FIG. 3, the control unit 20 of the printing apparatus 10 monitors whether there is a pairing request from an external apparatus (step SA1). The pairing request is made by transmitting a signal requesting pairing to the printing apparatus 10 in accordance with a predetermined protocol related to Bluetooth.
When there is a pairing request (step SA1: YES), the control unit 20 acquires the device name of the external device that has made the pairing request and the BD address (identification information uniquely assigned to the Bluetooth device). (Step SA2).
Here, when receiving a pairing request, the control unit 20 of the printing apparatus 10 communicates with the external apparatus that has made the pairing request according to a procedure according to a corresponding protocol, and acquires a device name and a BD address. To do.
The BD address corresponds to “identification information”.

Next, the control unit 20 refers to the non-permission list stored in the storage unit 22 (step SA).
3).
The non-permission list is a list in which BD addresses of external devices that do not permit pairing are registered by a method described later. The control unit 20 does not perform pairing even when there is a pairing request from an external device having a BD address registered in the non-permission list.

Next, the control unit 20 determines whether or not the BD address acquired in Step SA2 is registered in the non-permission list (Step SA4).
When the BD address is registered in the non-permission list (step SA4: YES), the control unit 20 does not perform pairing with the external device that has made the pairing request, and indicates that pairing has failed according to the protocol. A pairing confirmation signal including information is returned (step SA5).

If the BD address is not registered in the non-permission list (step SA4: NO), the control unit 20 determines whether the printing apparatus 10 is ready to perform printing (step SA6).
For example, printing cannot be executed when an error occurs in the transport mechanism or the printing mechanism, when the cover is open, or when the paper is out. Based on the input from the sensor unit 25, the control unit 20 determines whether or not the printing apparatus 10 is ready to perform printing.

When it is not in a state where printing can be performed (step SA6: NO), the control unit 20 performs a corresponding process without performing pairing (step SA7). For example, the control unit 20 informs that a predetermined unit is not in a state where printing can be executed and that pairing is not performed. The reason why pairing is not performed in a state where printing cannot be performed is that a pairing availability sheet described later cannot be issued.

On the other hand, when printing is possible (step SA6: YES), the control unit 20 issues a pairing availability sheet (step SA8).

FIG. 4 is a diagram illustrating an example of a pairing availability sheet.
The pairing availability sheet includes the device name of the external device that has made the pairing request, and B
The D address is printed. The pairing permission / inhibition sheet shows the user's operation when pairing is permitted with the external device that made the pairing request, and the user when pairing with the external device that made the pairing request is not permitted this time. The information indicating the operation performed by the user and the operation performed by the user when the pairing with the external device that has made the pairing request is not permitted in the future including this time is printed.
The pairing availability sheet illustrated in FIG. 4 has areas A1 to A3 as areas.
Has two areas.
In the area A1, the device name of the external device that has made the pairing request and the BD address are printed.
In the area A2, information indicating that three modes 1 to 3 can be selected is printed. In area A2, mode 1 is a mode that permits pairing,
Mode 2 is a mode in which pairing is not permitted this time, and information indicating that mode 3 is a mode in which pairing is not permitted in the future including this time is printed.
In the area A3, information indicating a procedure for selecting one of the modes 1 to 3 is printed. Specifically, when the mode 1 is selected, the feed switch 24 is selected.
2 (Feed button) is pressed once in less than 1 second, and then the feed switch 242 is pressed once in 1 second or longer (hereinafter referred to as “first operation”). When mode 2 is selected, after the feed switch 242 is pressed twice in less than 1 second, an operation of pressing the feed switch 242 once in 1 second or longer (hereinafter referred to as “second operation”) is performed. When selecting mode 3,
After pressing the feed switch 242 three times in less than one second, an operation of pressing the feed switch 242 once in one second or longer (hereinafter referred to as “third operation”) is performed.

By recognizing that the printing apparatus 10 has issued a pairing availability sheet, a user (for example, a cashier person in charge) can recognize that the external apparatus has made a pairing request to the printing apparatus 10.

It is possible to notify what operation should be performed when instructing permission / non-permission of pairing.

After printing the pairing availability sheet, the control unit 20 monitors whether any of the operations printed on the pairing availability sheet has been performed (step SA9).
When any operation is performed (step SA9: YES), the control unit 20 determines which one of the first operation to the third operation is performed (step SA10).

When the first operation is performed (step SA10: “first operation”), the control unit 20 performs pairing between the printing apparatus 10 and the external apparatus according to the corresponding protocol (step SA11). Next, the control unit 20 responds with a pairing confirmation signal including information indicating that the pairing was successful according to the corresponding protocol (step SA12). Thereafter, the external apparatus can communicate with the printing apparatus 10 through a communication link after wirelessly connecting to the printing apparatus 10.

When the second operation is performed (step SA10: “second operation”), the control unit 20 does not perform pairing with the external device (step SA13).
Next, the control unit 20 responds with a pairing confirmation signal including information indicating that pairing has failed according to the corresponding protocol (step SA14). As a result, pairing based on the pairing request received in step SA1 is not performed.

When the third operation is performed (step SA10: “third operation”), the control unit 20 does not perform pairing with the external device (step SA15).
Next, the control unit 20 responds with a pairing confirmation signal including information indicating that the pairing has failed in accordance with the corresponding protocol (step SA16).
Next, the control unit 20 registers the BD address (BD address of the external device that has made the pairing request) acquired in Step SA2 in the above-described disapproval list (Step SA17).
). As a result, even if there is a pairing request later from the external device that has made the pairing request, pairing based on the pairing request is not performed.
