Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printing control method that allows Hangul characters to be printed more efficiently using a normal serial printer that performs a space operation after printing.

Hangul (Korean characters) is composed of a combination of a plurality of unit characters, and these unit characters are arranged at predetermined positions and determined to mean predetermined pronunciations.

FIG. 1 is an explanatory diagram showing the structure of Hangul characters, and FIG. 2 is a diagram showing the types of unit characters arranged in the corresponding blocks in FIG. 1.

In FIG. 1, the unit characters placed in block 1 represent initial sounds, the unit characters placed in blocks 2 and 3 represent vowels, and the unit characters placed in block 4 represent final sounds. The unit characters (graphemes) printed in each block are determined as shown in Figure 2, with 1 character in block 1, 9 characters in block 2, 5 characters in block 3, and 5 characters in block 4. It is a seed. One Hangul character is composed of two to four unit characters of different types.

Therefore, some blocks may not be printed depending on the characters. Figure 3 shows an example of a terminal device.

indicate data buffers, respectively.

When inputting Hangul characters using the keyboard KB, the Hangul characters are broken down into unit characters, and a key corresponding to each unit character is pressed. For example, the word ``Hangul'' is expressed in the Hangul alphabet as ``Lao tongue yo'', but when inputting the Hangul character ``R 廿YO'' on the keyboard, it is expressed as ``Rright''. J. It is broken down into unit characters 1to and 1Lyo, and keys corresponding to these unit characters are pressed. The input unit characters are encoded and transmitted to a printer, etc., but in order to indicate which part of the data is one Hangul character, there are characters! A delimiter (for example, a space or a specific code) is written.

In addition, to indicate that the data is in Hangul characters, the beginning of the data string in Hangul characters is
A character indicating a shift is attached. When printing Hangul character data with an ordinary printer, with conventional print control methods, it is not possible to judge in advance what unit characters will be transmitted, so each time a unit character is printed, the original Backspace (return) to print position
Was.

When Hangul character data in the order J is transmitted to the printer in the order of gu-to-L, the printer
The following operations are performed: old printing, one pressure instep-SP-1 toe printing, BSP, one pressure upper printing-SP-SP.

Note that BSP represents back space, and SP represents space operation. Further, the two space operations after printing RL are for moving to the printing position of the next character. As can be understood from the above description, the conventional printing control method requires many operation steps to print one Hangul character, and has the disadvantage that the printing speed of the printer cannot be increased. there was. The present invention is based on the above-mentioned consideration, and when printing Hangul character data inputted after being decomposed into unit characters by a serial printer with a space operation after printing, it is possible to print one Hangul character. It is an object of the present invention to provide a printing control method that controls the printing order of unit characters so that the number of operation steps required for printing is minimized.

Therefore, the printing control method of the present invention is a printing control method for a printing system that prints with a serial printer that receives Hangul character data consisting of a plurality of unit character data and performs a space operation after printing the character. a data memory for storing unit character data constituting the received Hangul character data, an area A1 for storing unit character data representing the initial sound, and an area for storing unit character data representing the vowel on the left side of the Hangul character. A3
a Hangul buffer having an area for storing unit character data representing a final sound, and an area for storing unit character data representing a vowel on the right side of a Hangul character; and unit character data output from the data memory. Hangul buffer writing control means for writing the Hangul buffer into the Hangul buffer, and a Hangul buffer reading device capable of reading unit character data from the Hangul buffer and sending it to the serial printer, and also sending backspace codes to the serial printer. control means, and the Hangul buffer write control means determines whether the unit character data output from the data memory represents an initial sound, a vowel on the left side of a Hangul character, and whether the unit character data output from the data memory Determine whether it represents a vocal sound or a vowel on the right side of Hangul characters, and use the above data according to the determination result.
The unit character data output from memory is converted into the above Hangul
Corresponding area A of the buffer (i is 1, 2, 3 or 4)
The Hangul buffer read control means is configured to write to areas Al, A3, and Hangul buffer of the Hangul buffer.
After reading the unit character data existing in A4 and sending it to the serial printer, and sending the unit character data in the areas Al, A3, and A4 to the serial printer, the unprinted units in the areas Al, A3, and A4 are read. Check whether there is character data, and if there is, send the backspace code to the above serial ● printer, and then write the above areas Al, A3, A.
The unprinted unit character data existing in 4 is converted to the above serial number.
If there is no character data, the unit character data existing in the above areas is sent to the serial printer. Hereinafter, the present invention will be explained with reference to the drawings. Figure 4 shows part 1 of the present invention.

Data sent from the keyboard KB or the communication line is temporarily stored in the data memory 1.

A strobe pulse is attached to the end of the data.
For example, the key input procedure or the structure of the received message when printing 1 Na fortune, such as J right LSP Yuki SPJ, at the end of each data of J and RuJ, as mentioned above, the data. A delimiter code (strobe pulse SP) is attached to determine which part is one Hangul character. When the timing control unit 2 receives the strobe pulse, it notifies the data memory 1 that the transmission of a series of data sequences has been completed, and also sends a notification to the busy FF 3.
is set to send a busy signal to the outside. The function distributor 4 receives and distinguishes functional characters such as Hangul shift, alphanumeric shift, and line feed, and sends out signals corresponding to each functional character. Hangul FF5 is set for Hangul shift. Hangul column selection section 6
As shown in FIG. 8, for example, the system is configured with a ROM, and each input unit character data (unique code assigned to each unit character) is first read with reference to FIGS. 1 and 2. This is to determine which of blocks 1 to 4 of the Hangul characters that the code belongs to and to detect the delimiter SP. As a result of the determination, for example, if the code belongs to block 1, the output terminal of the Hangul column selection unit 6 connected to the AND circuit 14-1 is set to logic r1,
If the code belongs to block 2, AND circuit 1
The output terminal of the Hangul column selection unit 6 connected to 4-2 is set to logic RlJ. The same applies when codes belonging to block 3 and block 4 are input. As mentioned above, one Hangul character is written in block 1.
A delimiter SP is attached next to the last unit character data (unit character code) that is composed of two to four unit characters belonging to blocks 4 to 4 and constitutes one Hangul character. When the output 5-ram selection section 6 detects this delimiter SP, it sends the detection output to the Hangul buffer control section 7 as a print start signal.
The Hangul buffer 8-1 is divided into four areas, the first area stores unit character data belonging to block 1, the second area stores unit character data belonging to block 2, and the second area stores unit character data belonging to block 2. Unit character data belonging to block 3 is stored in the area 3, and unit character data belonging to block 4 is stored in the fourth area. The same applies to the Hangul buffer 8-2. The Hangul buffer control unit 7 controls which of the Hangul ● buffer 8-1 or the Hangul ● buffer 8-2 stores unit character data. The Hangul/buffer space selection section 9 controls the sending of unit character data stored in the Hangul buffer 8-1 or 8-2, the sending of back space codes, and the like. The busy control section 10 receives a machine ready (machine busy) signal and sends out a busy signal. Machine Ready signal MR
Accordingly, it can be known whether the printer PR has printed one character or one signal, or has not printed one character or signal. FIG. 5 shows the print head 16, in which 16-a is alphanumeric type, 16-1 is a unit character type group arranged in block 1 of FIG. 1, and 16-2 is a group of unit characters arranged in block 2. 16-3 is a unit character type group placed in block 3, and 16-4 is a unit character type group placed in block 4.

Next, the operation of the apparatus shown in FIG. 4 will be explained.

Function - When the distributor 4 detects a Hangul shift, the Hangul FF5 is set, and the output signal of the logic r1 is applied to the AND circuits 14-1 to 14-4.
supplied to When the unit character data is sent out from the data memory 1, the Hangul column selection unit 6 determines which block the unit character data belongs to and outputs a logic r1yo signal to one of the corresponding output lines. do. for example,
If the unit character data belongs to block 1, the Hangul column selection unit 6 sends a logic R to the AND circuit 14-1.
Send lJ. The Hangul buffer control unit 7 receives the activation signal from the Hangul column selection unit 6 and selects either the Hangul buffer 8-1 or 8-2. It is now assumed that Hangul Batsufu 5A8-1 has been selected. The unit character data is stored in the Hangul buffer 8-1 via the signal line 11, signal line 12, and AND circuits 14-1 to 14-4. When all of the unit character data constituting one Hangul character is read out from the data memory 1, the Hangul column selection unit 6 detects a character delimiter.

When the character delimiter is detected, the Hangul column selection section 6 issues a Hangul ● buffer switching command to the Hangul buffer control section 7. At the same time, a character delimiter code is sent to the buffer/backspace selection unit 9 via a signal line (not shown). The Hangul buffer control unit 7 selects the Hangul buffer 8-2, so that the Hangul character composition signal data is stored in the Hangul buffer 8-2. While character data in the Hangul buffer 8-1 is being extracted and sent to the printer PR, unit character data can be stored in another Hangul buffer 8-2. Similarly, while extracting the unit character data in the Hangul buffer 8-2 and sending it to the printer,
Hangul●It is possible to store unit character data in buffer 8-1. Needless to say, if both the Hangul buffers 8-1 and 8-2 are used, no data will be accepted. The buffer/backspace selection unit 9 senses the contents of the Hangul buffers 8-1 and 8-2 and selects the unit character data node so that the operation steps required to print one Hangul character are minimized. It controls the transmission and backspace code transmission. 6th
The figure explains the operation of the buffer/backspace selection section 9, in which A1 is an area where unit character data belonging to block 1 is stored, A2 is an area where unit character data belonging to block 2 is stored, and A3 is an area where unit character data belonging to block 2 is stored. is the area where unit character data belonging to block 3 is stored, A4 is block 4
Each indicates an area in which unit character data belonging to is stored.

Note that during the Hangul shift, logic r1 is sent to the signal line 13. Further, the signal line 14 is composed of three lines and is used to select any one of the AND circuits 15-1 to 15-3. First, the selection unit 9 sends unit character data stored in areas Al, A2, or A3 from the Hangul ◆ buffer 8-1.
Note that if all unit character data in areas 8, , A2, and A3 are stored, data in area A1 takes priority. The unit character data from buffer memory 8-1 is 0.
R circuit 12-1, AND circuit 15-1 and 0R circuit 13
The data is then sent to the printer PR. The printer PR performs printing based on this data. The printer PR is an ordinary serial printer in which the print head 16 moves by one character (in this case, one unit character) when one printing operation is performed. The area where the data was sent is cleared. Now, assuming that unit character data in area A1 has been sent, it is checked whether unit character data is stored in the remaining area A3 or A4, and if unit character data exists, the next time the backspace code is sent. It will be done. The backspace code is sent when the printer PR side notifies the completion of the printing operation. The backspace code is sent out from the Hangul/backspace selection unit 9, and is sent to the 0R circuit 12-1, AND circuit 15-1, 0
It is sent to the printer PR via the R circuit 13. During this time,
Areas A3 and A4 are checked. If unit character data is stored in area A3, when the completion of the backspace operation is notified, the above unit character data will be stored in printer P.
Sent to R. When unit character data no longer exists in areas Al, A (3, A1, check whether unit character data exists in area ~. If it exists, this unit character data is transferred to the printer PR side after the printing operation is completed. The unit character data in the Hangul buffer 8-2 is also sent to the printer PR in the same way.FIG. 7 shows the printing operation order according to the present invention and the printing operation order by the space cut type printer. It is.

In the figure, 1 to 4 indicate printing operations for unit characters arranged in blocks 1 to 4, BSP indicates a backspace operation, and SP indicates a space operation. In general serial printers, a space is automatically created when a single character is printed, but with a space-cut printer, there is no space even when a single character is printed. This is a type of space that is only printed after receiving a space code to print. 7A shows the order of printing operations according to the present invention, and the opening of FIG. 7 shows the order of printing operations by a space-cut type printer. As can be seen from this figure, according to the present invention, one Hangul character can be printed with the same number of operation steps as when using a space-cut printer, and the printing speed is also space-cut. The printing speed can be made equal to the printing speed when using a printer of this type. As is clear from the above description, the present invention temporarily stores a plurality of unit character data constituting Hangul character print data in a Hangul buffer, and stores unit character data belonging to the left column of Hangul characters first. ●Hangul data is extracted from the buffer and sent to the printer with a backspace code added, and then the unit character data belonging to the right column of the Hangul character is extracted from the Hangul buffer and sent to the printer, so there is no need to use a special printer. This has the effect of allowing characters to be printed at high speed.
