Description

Detailed Description of the Invention

[0001]

The present invention relates to ECR, PC-POS.
For example, the present invention relates to a printer used for issuing receipts of a sales management system.

[0002]

2. Description of the Related Art Conventionally, in a receipt issuing printer used for printing an ECR, a PC-POS, a sales management system, etc., a receipt provided to a purchaser has so-called standard information other than the purchased item and its price. The company and distributor names, commercial messages, receipt end messages, etc. are printed. Such printing is performed based on output from the host computer side together with output information such as calculation results by the host computer.

[0003]

When such print data is output from the host computer, it is necessary for the host computer to store the print data in the storage means and repeatedly read the print data. When such standard print data is output from the host computer to the printer side, a storage means for the data is required on the host computer side, and the load on the host computer side such as the reading process becomes heavy. Further, when the print data is changed, the software on the host computer side and the print data must be changed as necessary.

By the way, in order to reduce the load on the host computer side due to such standard print data processing, a method of utilizing the RAM on the printer side can be considered. That is,
After the power is turned on, the print data is once transferred from the host computer to the printer, written in the RAM on the printer side, and the control code is sent from the host computer to the printer side, so that the RAM side prints each time the control code is received. This is a method of executing data. However,
In such a printing method, when the power is turned off, the data in the RAM is lost, so that the power cannot be turned off.
Further, when the power is turned off, after the power is turned on, the print data must be transmitted from the host computer to the printer. Therefore, in order to avoid loss of data in the RAM during non-printing, if power is supplied to the printer, power consumption will increase, and in the case of data transfer from the host computer to the printer, Since the processing is required, the load on the host computer side is still large and the load on the host computer cannot be reduced.

Therefore, according to the present invention, the standard print data can be arbitrarily written or changed on the printer side without changing the software on the existing host computer side, and the load on the host computer side is reduced. , It is intended to provide a printer capable of issuing a receipt.

[0006]

A printer of the present invention is a printer (4) used for issuing a receipt for printing print information from the host computer on a receipt paper in cooperation with a host computer (2), Storage means (R) for storing the standard print data to be printed on the receipt paper separately from the print information from the host computer.
An OM 43) and a means (CPU 40) for executing the print data stored in the storage means at the time of power-on or by a control code from the host computer side are provided to perform standard printing on the receipt paper. Characterize.

[0007]

The printer of the present invention is provided with the storage means for arbitrarily writing the standard print data without changing the software of the existing host computer. As standard print data in this storage means, print data such as page length, margin, line feed pitch, and other default set changes, and logos, commercial messages, receipt end messages, etc. that represent a fixedly set company name on receipts, etc. To store.

There is provided means for executing the data stored in the storage means when the power is turned on or by a control code from the host computer side, the print data is output from the storage means, and the print data is received. Printed on paper.

As described above, since the standard print data is output from the storage means on the printer side and printed, it is possible to reduce the load on the existing software on the host computer side and the load such as data transfer.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the embodiments shown in the drawings.

FIG. 1 shows an embodiment of the printer of the present invention. The host computer 2 is installed as a data processing device that executes data processing in the sales management system. In this host computer 2,
An input device (not shown) is connected to optically read a bar code or the like attached to a product, collect read data, issue a receipt, and perform various sales management. A printer 4 according to the present invention for issuing a receipt for issuing a receipt to a customer is connected to the host computer 2.

The printer 4 is provided with a central processing unit (CPU) 40 as a data processing means for exchanging data with the host computer 2 and performing original data processing. The host computer 2 is connected to the CPU 40 through an interface (I / F) 41, and control data and the like are added from the host computer 2 for standard printing. In this case, the CPU 40 performs print control, and in particular, constitutes a means for executing fixed-size print data by turning on the power or a control code from the host computer 2.

Further, the CPU 40 is linked with a RAM 42 as first writable storage means for temporarily storing data during data processing and a ROM 43 as second storage means for storing standard print data and programs. Has been done.

As the ROM 43, for example, an EPROM which can be arbitrarily written is used in order to allow the printer 4 to write fixed-size print data. As standard print data to be written in this ROM 43, by default change of set such as page length, margin, line feed pitch,
There are logos, company messages, receipt end messages, etc. that represent company names that are fixedly set on receipts.

Tables 1 and 2 show addresses and their stored contents in the ROM 43. That is, the ROM 43 stores printer initial settings, printer mechanism control programs, and standard print data to be executed when the power is turned on.

[0017]

[Table 2]

A driver 44 is connected to the CPU 40 as an output means for outputting print data, and a printer mechanism section 46 is connected to the output section of the driver 44. The printer mechanism unit 46 includes a print head, a print sheet feeding mechanism, and the like, receives print data output from the CPU 40, and prints on the print sheet. Further, a receiver 45 is connected to the printer mechanism section 46, and the receiver 4
Reference numeral 5 denotes a printer mechanism unit 46 that indicates the start and end of printing.
Data from the receiver 45
It is input to the PU 40.

Next, FIG. 2 shows an example of a receipt printed by the printer 4. The receipt 6 is, for example, for printing and issuing necessary items for each sale on a receipt paper in the form of a belt, and A and C are standard printing units,
B is an atypical printing portion. That is, the standard print parts A and C are
It is the printing part of company name, telephone number, commercial message, etc., and based on the fixed data stored in the ROM 43 on the printer 4 side, the printer 4 side can perform its own operation according to the power-on or the control code from the host computer 2. It is printed. The atypical printing portion B is a portion for printing variable data by exchanging data with the host computer 2, and is printed based on data input and calculation on the host computer 2 side.

Next, the standard printing operation will be described with reference to the standard printing program based on the control code shown in FIG.

When a control code arrives from the host computer 2, this fixed form printing program is executed. That is, in step S1, it is checked whether or not data has been received from the host computer 2 after the initial setting based on power-on. If the data has not been received, the process waits in step S1 to repeatedly monitor data reception. If data is received from the host computer 2, step S
2, the received data is ESC, “m”, n and 1 ≦
Check whether n ≦ 8.

In step S2, the received data is ESC, "
If m ″, n and 1 ≦ n ≦ 8, step S3
After setting the start address to the address of the print data, the process proceeds to step S4. In step S4, the data is fetched from the ROM 43 using the address of the print data, and the process proceeds to step S5.

In step S5, it is determined whether or not the data taken out from the address is FF _H. If it is not FF _H , the process proceeds to step S6 to perform printing processing of the taken out data. Then, in step S7, after incrementing the address of the print data, the process proceeds to step S4.

In step S2, ESC, "m", n
If it is determined that 1 ≦ n ≦ 8 is not satisfied, the process proceeds to step S8, and the received data is printed, and then the process returns to step S1. Also, when the data extracted in step S5 is FF _H , the process returns to step S1.

Standard printing is performed based on such program operation. In this standard printing, for example, as shown in FIG. 2, the company name “Starprint Co., Ltd.”, a telephone display and a telephone number are printed on the upper column side of the receipt 6. next,
After the sales amount and the like are printed based on the print information from the host computer 2, the host computer 2 again
Outputs the control code. Based on this control code, the standard print data is read from the ROM 43 on the printer 4 side, and in this embodiment, the standard message such as the commercial message "Thank you very much", business hours, etc. is printed. When the receipt 6 is issued, the standard print program is executed for each receipt issuing unit, that is, for each tabulation, and standard printing is performed.

In the embodiment, the host computer 2
The execution of the standard print data based on the output of the control code from the printer has been described. However, the CPU 40 is operated based on the power supply to the printer 4, and the standard print data stored in the ROM 43 is executed. You can

[0027]

As described above, according to the present invention, when the standard print data such as the company name, the telephone number and the commercial message is repeatedly printed on the receipt, the standard print data is printed each time the printer is turned on or the power is turned on. Since there is no need for the host computer to send data, the load on the host computer can be reduced, and control codes such as page length and left / right margin settings are written to the ROM instead of the standard print data and executed when the power is turned on. The default value can be changed, which is extremely useful in practice, and can contribute to the simplification of receipt issuance when the system such as the sales management system is executed.
