Description

PAPER SELECTION PRINTING METHOD OF ECR}

The present invention relates to a recording paper selective printing method of a cash register, and more particularly, to a recording paper selective printing method of a cash register which can reduce unnecessary consumption of the recording paper by selectively outputting the receipt and audit paper.

A cash register is a device that processes various data accompanying product sales and informs a user of the result so as to facilitate information management. Cash registers range from simple sales offices to point-of-sales systems that can comprehensively manage the distribution economy, such as market research and inventory research.

1 is a block diagram of a general cash register. As shown in FIG. 1, the electrical configuration of the cash register includes a key input unit 20 for generating various key codes for mode designation and money registration, and a cash input according to a key code input while kissing the key input unit 20. The central processing unit 10 for designating the mode of the register and performing various functions in the designated mode, the ROM 30 storing a system operation program, and storing various data generated during a program or a transaction set by the user. Printer 40 for displaying various types of information visually under the control of the RAM 40, the central processing unit 10, and a printer for printing various processing results into documents such as resin or audit paper under the control of the central processing unit 10. (70), the buzzer unit (80) for alarming the malfunction or abnormal operation of the device, and receives the commercial AC power is converted into various types of DC power required to drive the cash register And the interface unit 50 for relaying data to and from the power supply unit 90 supplied to each part of the circuit including the central processing unit 10 and the printer 70, the display unit 60, and the like.

In a conventional cash register having the above-described configuration, when a user registers a transaction history of a product, the contents are printed according to a predetermined universal receipt form.

By the way, the conventional cash register is not able to use the cash register itself unless the registration details are printed after the transaction details are registered.

Therefore, when the transaction details are registered, even if unnecessary, all receipts and audit papers should be printed at all times, so that the consumption of the recording paper increases from the user's point of view.

Accordingly, the present invention has been made in order to solve the above-described problems, the recording paper selective printing method of the cash register to reduce the unnecessary consumption of the recording paper by selectively outputting the receipt and audit paper when the transaction history is registered The purpose is to provide.

The present invention for achieving the above object comprises the steps of determining whether a printing command for the transaction details is input in a state in which the control key code value for selectively printing the receipt or audit paper is set in advance; Waiting for input of a factor control keycode value when a printing command for transaction details is input as a result of the determination in the step; And if the print control keycode value is input, analyzing the value and executing the output according to the corresponding recording paper output scheme.

In the printing control key code value waiting step, if the printing control key code value is not input for a predetermined time, it may be preferable to output the printing paper printing method.

The outputting of the recording paper may include outputting the resin control paper and the audit paper when the print control key code value is an output value of the resin control and the non-audit paper, and the print control key code value is the resin paper. And if the audit paper is output at the same time, both the resin and the audit paper are output, and if the control keycode value is the resin output value, only the receipt is output, and if the print control keycode value is the audit paper output value, only the audit is output. do.

It may be desirable to skip the printer initialization routine if the print control keycode value is an unprinted and non-audit value.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

2 is an exemplary key configuration diagram of a cash register according to the present invention. In practice, arrangement and number (functions) of keys may be changed or added according to the height or ease of use of a model.

As shown in Fig. 2, the key configuration of the cash register includes a mode selection switch 21 used for designating a desired operation mode among various operation modes, and a number of items or various numbers required for inputting a product name requiring temporary change. , Letter / digit key group 27, letter item group 25 used to designate a desired item, and function key group 23 used to execute a desired function.

The function key group 23 defines four 'factor control keys 23a to 23d' required by the present invention. Each print control key 23a to 23d is defined corresponding to the print control keycode value input by the user.

3 is a view showing a printing control table according to the printing of the control key code value according to the present invention, each of the control key code values ('00', '10', '01', '11') by the user Input will be specified. As shown in Fig. 3, the control key code values are '00' for printing the resin and audit paper at the same time, '10' for printing only the receipt, '01' for printing only the audit, and '11' for the resin. And not to print all of the audit paper.

Figure 4 is a flow chart for explaining the recording paper selective printing method of the cash register according to the present invention.

First, the user has to set the factor control keycode value through the key input unit 20 to set in advance, the order of the first 'keycode value 1' using the numeric key 27 in the program mode After that, the four keystroke control keycode values are set in such a manner that the keycode value 2 is input and then the corresponding print control keys 23a to 23d are input.

Subsequently, in step S40, when a printing message is input as in step S42 while a general function of the cash register, for example, driving of a display unit, key input, and performing a function according to the input key, is performed. It waits whether the printing control keys 23a to 23d are input.

Subsequently, when the factor control keycode is input, the input keycode value is analyzed and the output of the receipt or audit paper is determined according to the result of the analysis to execute the output of the transaction details.

That is, in step S44, it is determined whether the value of the input control keycode value is '11'. As a result of the determination in this step S44, if the value is '11', the process proceeds to step S46 and the printer After skipping the printer initialization routine such as inspection of abnormality or inspection of recording paper, the process proceeds to step S48 to display transaction details and open the cash drawer.

On the other hand, as a result of the determination in step S44, if the value is not '11', the process proceeds to step S50 to execute the printer initialization routine. Subsequently, in step S52, it is determined whether the printing control keycode value is '00'. If the determination result in this step 52 is '00', the flow advances to step S54, and the receipt and auditing are performed. After outputting the transaction history using all the papers, the process proceeds to step S48.

On the other hand, as a result of the determination in step S52, if the control key code value is not '00', the process proceeds to step S56 to determine whether the value is '01'. As a result of the determination in this step S56, if the key code value is '01', the process proceeds to step S58, after printing the transaction details only in the receipt, the process proceeds to step S48.

On the other hand, as a result of the determination in step S56, if the key code value is not '01', that is, '10', the process proceeds to step S60 to print the transaction details only as an audit. Next, the process proceeds to step S48.

The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the technical idea of the present invention.

According to the present invention as described above, it is possible to selectively output the receipt and audit paper, thereby reducing the unnecessary consumption of the recording paper.
