Has a function of winding a printed journal according to a command from the print storage control unit 30 or manually, and after winding, it can be removed from the printer 1 and stored.

Further, the cutter unit 114 has a function of cutting a printed receipt according to a command from the print storage control unit 30 or manually, which will be described later, and is configured so that the cut receipt can be handed to a customer. .

Next, the operation will be described. First, the normal operation will be described. The print storage control unit 30 analyzes a print command input from a higher-level device (for example, a central processing unit), causes the switching unit 40 to print the receipt print data by the receipt printer 100 via the control line C1, and prints the journal print data. To be printed by the receipt journal printer 1. On the other hand, the switching unit 40 causes the receipt print data to be input to the print data signal line D1 on the receipt printer 100 side and the journal print data to be input to the print data signal line D2 on the receipt journal / printer 1 side. Connect D1 and D2. Then, the connection completion is notified to the print storage control unit 30 via the control signal line C1.

As a result, the print storage control unit 3 is transferred from the host device.
The print data input to 0 is input to the switching unit 40 via the print data signal line D3, the receipt print data is printed by the receipt printer 100 via the switching unit 40, and the journal print data is also used as the receipt journal. It is printed by the printer 1.

Further, in the receipt printer 100, the receipt is cut out when printing of the receipt is completed in accordance with a command from the print storage controller 30.

On the other hand, the receipt journal printer 1
In this case, since the journal print data is printed, only the command for winding the journal in the winding unit 113 is output from the print storage control unit 30, and the receipt is cut by the cutter unit 114.
The command to cut with is not output.

Next, the case where a failure occurs will be described. This failure can be classified into a failure of the receipt printer 100 and a failure of the receipt journal / printer printer 1.

First, a case where a failure occurs in the receipt printer 100 will be described. The fault of the receipt printer 100 is divided into three types: a fault of the driver 101, a fault of the printing mechanism unit 102, and a fault of the cutter unit 103, and each device is provided with a sensor (not shown) that detects this fault. The detection signals of the sensors are input to the failure detection unit 20 via the detection signal lines S1 to S3, respectively.

Now, the driver 101 and the printing mechanism section 102
Alternatively, if a failure occurs in any of the cutter units 103, the failure detection unit 20 determines that a failure has occurred in the receipt printer 100, and notifies the print storage control unit 30 of the failure occurrence via the detection signal line S4.

Upon receipt of this notification, the print storage controller 30
The switching unit 40 is instructed via the control signal line C1 to print the receipt print data with the receipt journal printer 1 and store the journal print data in the non-volatile memory 10. On the other hand, the switching unit 40 causes the receipt print data to be input to the data signal line D2 on the receipt journal / printer 1 side, and the journal print data to be input to the data signal line D4 on the non-volatile memory 10 side. Connect D4. Then, the completion of switching is notified to the print storage control unit 30 via the control signal line C1.

As a result, the print storage control unit 3 is transferred from the host device.
The print data input to 0 is input to the switching unit 40 via the print data signal line D3, the receipt print data is printed via the switching unit 40 in the receipt journal printer 1, and the journal print data is non-volatile. Stored in the sex memory 10.

The receipt journal printer 1 is also used.
In this case, since the receipt print data is printed, the print storage control unit 30 outputs a command for cutting the receipt by the cutter unit 114, and does not output a command for winding the journal by the winding unit 113.

In this way, the receipt printer 100
Even if a failure occurs in the printer, the receipt can be printed by the printer 1 also serving as the receipt journal, and the journal can be stored in the non-volatile memory 10. Since the journal is reserved, it is sufficient to read it from the non-volatile memory 10 at the end of work.

Next, the printer 1 also serving as the receipt journal
A case in which a failure occurs will be described. The failure of the receipt journal / printer 1 is divided into four, that is, the failure of the driver 111, the failure of the printing mechanism section 112, and the failure of the winding section 113 and the cutter section 114. (Shown in the figure) is provided, and the detection signals of these sensors are detected signal lines S5 to S
It is input to the failure detection unit 20 via 8.

Now, the driver 111 and the printing mechanism section 11
2. When a failure occurs in either the winding section 113 or the cutter section 114, the failure detection section 20 determines that the failure has occurred in the receipt journal printer 1, and the failure is printed and stored via the signal line S4. Notify the control unit 30.

Upon receipt of this notification, the print storage controller 30
The switching unit 40 is instructed to store the journal print data in the non-volatile memory 10 via the control signal line C1. On the other hand, the switching unit 40 connects the data signal line D4 so as to input the journal print data to the data signal line D4 on the nonvolatile memory 10 side. Then, the completion of switching is notified to the print storage control unit 30 via the control signal line C1.

As a result, the print storage control unit 3 is transferred from the host device.
The print data input to 0 is input to the switching unit 40 via the print data signal line D3, and the journal print data is stored in the non-volatile memory 10 via the switching unit 40.

In this case, since the receipt printer 100 is operating normally, the print memory controller 30 causes the receipt printer 100 to print the receipt print data,
In addition, the receipt printer 100 is controlled so that the cutter unit 103 cuts the receipt.

In this way, the journal can be stored in the non-volatile memory 10 even when the receipt journal / printer 1 fails.
