The present invention relates to a method of printing a Receipt & Journal (hereinafter referred to as R / J) printer in a point of sales system, and in particular, it shares the role of Hangul printing in a central processing unit and an R / J printer. The present invention relates to a method of improving printing speed.

In general, POS system used for merchandise sales management has an R / J printer that prints a receipt for customers and a business store audit sheet. The configuration is as shown in FIG.

That is, the central processing unit (1) to control the overall operation of the POS system as a whole, the ROM (3) to store various initial data and control programs, such as Hangul type and port data, and the data management and printing work according to product sales RAM 4 for temporarily storing various processing data according to the present invention, in-line and on-line boards 5 and 6 connected to the central processing unit 1, and various data and command keys for inputting the central processing. A key input unit 11 for transmitting to the device 1, a key input control unit 7 for controlling the operation of the keyboard 11 under the control of the central processing unit 1, and a display unit for displaying the state of the system (12), a display control unit (8) which controls the operation of the display unit (12) under the control of the central processing unit (1), and reads bar code information to the central processing unit (1). Optical Bar Code Reader 13 and the above to An optical bar code reader controller 9 for controlling the operation of the optical bar code reader 13 under the control of the angular processing apparatus 1, an R / J printer 14 for printing receipts and audit papers; An R / J print control unit 10 controlling the operation of the printer 14 under the control of the central processing unit 1, and the respective control units 7, 8, 9, 10 of the central processing unit 1; It consists of an input / output board 2 connected between them.

In the POS system having the above-described configuration, in order to print Korean characters during R / J printing, the following two methods were mainly used. In the first method, when the Hangul seconds, Chinese words, and the final words are transmitted to the central processing unit 1 through the key input unit 11, the key input control unit 7, and the input / output board 2, the central processing unit 1 uses the combined code. Was made and delivered to the R / J print control unit 10.

At this time, the R / J print control unit 10 analyzes the combination code to create a second, middle, and final font address for each type, and finds and combines the corresponding font to form the R / J printer 14. Hangul was printed on.

However, according to the above method, the R / J print control unit 10 analyzes data received from the central processing unit 1 and stores the data in a buffer so as to control printing according to the speed of the R / J printer 14. After that, printing was necessary. Therefore, there is a disadvantage in that the maximum speed of the printer with respect to the number of lines that can be taken per second is limited as much as required for the data analysis.

In the second method, when Hangul seconds, Chinese, and Jong-seong are passed to the CPU 1, the Hangul combination code is written by the CPU 1 and an independent address for all Hanguls to be taken by the R / J printer 14 is obtained. Was prepared and delivered to the R / J print control unit 10. In this case, the R / J print control unit 10 configures a Hangul port by using an address for each Hangul, and prints it on the R / J printer 14.

However, according to the second method, since the R / J print control unit 10 provides an address for all the Hangul characters so that the R / J print control unit 10 can immediately find and print a font, the CPU 1 Since the amount of interface data of the R / J print controller 10 is increased, the interface time is long, and since the R / J print controller 10 has to have all Korean fonts, there is a disadvantage in that the required ROM area is increased.

Accordingly, an object of the present invention is to provide a method for efficiently printing Korean characters by sharing roles in the central processing unit and the R / J print control unit.

Another object of the present invention is to provide a Korean printing method that can improve the printing speed of the R / J printer.

Another object of the present invention is to provide a Hangul printing method that can reduce the memory size by reducing the amount of interface data between the central processing unit and the R / J print control unit.

It will be described below with reference to the accompanying drawings of the present invention.

1 is a system block diagram to which the present invention is applied, and its configuration is the same as described above.

FIG. 2 shows that the central processing unit 1 receives the seconds, middle, and final characters of the Hangul from the keyboard 11, analyzes the Hangul types, and sends the seconds, middle, and bells to the R / J print control unit 10 according to each type. It is an illustration of the 1st and 6th table | surface of the table | storage which stores data.

FIG. 3 is an example of a buffer in which the central processing unit 1 analyzes the Hangul type and finds and stores data to be sent to the R / J print control unit 10 in a table according to each type.

FIG. 6 is an exemplary view of a buffer in which the controller 10 stores font data for one Korean character to be printed by combining font data.

8 is an exemplary diagram of a combined Hangul code table.

9 is an exemplary diagram of the upper address table for each Hangul type to be sent to the R / J print control unit 10.

The present invention will be described in detail based on the above configuration.

First, the role sharing of the central processing unit 1 and the print control unit 10, which are the main points of the present invention, will be described. The R / J print control unit 10 has a predetermined byte (9 bytes for the first type of first type): Six types of Hangul, Korean, Korean, Korean, and Korean fonts are built-in, and their start addresses are collected for each type. When the byte (higher address, initial start address, neutral start address, and final start address) is received, it is stored in the print control unit as the upper address (XX) and the initial or neutral or final start address (YY) according to the type without Hangul type analysis. Create a font start address (XXYY) for each type (if "is", as shown in Figure 5, "a" is 0610 and "ㅏ" is 0682) Print by eliminating the need for analysis of the type of Hangul. In addition, the central processing unit 1 may be configured as 2 bytes (first 1) as the initial, neutral, and final codes shown in FIG. 8 when the Hangul should be printed by the keyboard 11 or other input regardless of the operation of the print control unit 10. Bits 1 and the remaining 15 bits each have 5 bits of Hangul combination code of FIG. 8's initial, neutral, and final code), and 6 types of Korean characters are determined as shown in FIG. The upper address of the relevant type of the figure, the initial, neutral, final, and start address are read in the table of FIG. 2 stored in the CPU 1 according to each type using the initial, neutral, and final codes to correspond to a single Hangul character. A font address of 4 bytes (upper address, initial, start address, neutral start address, and final start address depending on the type) is formed and sent to the print control unit 10 (if 48 bytes when printing 12 Korean characters).

In this way, the print control unit 10 receives the font start address, not the Hangul code, and immediately reads the embedded font, and the central processing unit 10 prints the Hangul regardless of the print operation. When printing Korean characters continuously by making a font start address and sending it to the print control unit 10 in the same manner as described above, the print control unit 10 does not need to analyze the Hangul code so that printing can be performed as quickly as possible.

This process is described in more detail based on FIG. 7 as follows.

After the keyboard 11, the key input control unit 7, and the input / output board 2 are sealed and the Hangul, Chinese, and Jongsi are transmitted to the central processing unit 1, the central processing unit 1 proceeds to step (B). To make Hangul combination code. After completion of step (B), in step (C), each type is analyzed as follows based on the Hangul type shown in FIG. In other words, judging the presence of a consonant, if there is a consonant, the neutrality is examined.

If it is determined that the first neutrality (ㅏ, ㅑ, ㅓ, ㅕ, ㅣ) is a result of the test, the presence or absence of finality is determined. If the finality is present, the Hangul type is determined as the first type.

However, if it is determined that the neutrality test results in the second neutrality (ㅗ, ㅛ, TT, ㅠ, ㅡ), then check for the presence of finality, and if there is a finality, the Hangul type is determined as the fourth type. .

If it is determined that the neutral test results in the third neutrality, as described above, the presence or absence of the finality is checked, and if there is a finality, the Hangul type is determined as the sixth type.

When the analysis of the Hangul type is completed through the above process, the CPU 1 finds the second, middle and final fonts of each type in the table of FIG. 2 and stores them in the buffer of FIG. After the font storing is completed, the central display apparatus 1 proceeds to step (E) and inputs the Hangul type, the second, the middle, and the final address stored in the buffer of FIG. 3 in the R / J print controller 10 to the input / output board ( 2) to the R / J print control unit 10 through.

After performing step (E), in step (F), the R / J print control unit 10 has a portion indicating a third degree data Hangul type and a portion indicating seconds, middle, and finality, as shown in FIG. By forming a font start address for each type, the font data is read out from the ROM 3 and stored in a buffer as shown in FIG. 6 so that the R / J printer 14 can print it. The R / J printer 14 is controlled to perform a print operation.

As described above, the central processing unit analyzes data to be taken next to the R / J printer while printing and transmits the data to the R / J print controller so that the R / J printer can achieve the maximum printing speed. The amount of interface data between the central processing unit and the R / J print control unit can also be reduced, thereby reducing the efficiency.
