Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a printing control device suitable for use in a system in which a printer to be connected is not specified as either a Kanji code system or a Kana code system.

[Prior art and its problems] Conventionally, in a system that can handle documents in a kanji code system, as a printout target,
When an alphanumeric printer is connected, since the Kanji code cannot be printed, there is a device that prints a space or the code itself in that part.

However, such conventional devices have a drawback in that when it is desired to print out a document containing a mixture of Chinese characters, the content cannot be printed out in an easily readable manner.

[Purpose of the invention] This invention is capable of printing out the document contents in an easily legible state even when the character encoding system of the document to be output does not match the character encoding system of the printer to be output. The purpose is to provide a printing control device that can perform the following functions.

[Key points of the invention] This invention is based on an input buffer that stores the character code string of the document to be printed, and an output receiving means for receiving a designation signal indicating whether the target printer is a Kanji code printer or a Kana code printer; and if the designation signal indicates a Kanji code printer, synchronizing the character code stored in the input buffer from the printer; control means for reading and outputting the data as is to the printer in accordance with a signal; and when the designated signal indicates a kana code printer, means for reading character codes stored in the input buffer character by character and determining the code system thereof; , code conversion for converting the character code into a kana code or a kana code string with a predetermined correspondence according to the code system of the output target printer when the code system of the character code determined by the discrimination means is not a kana code system; It is configured to print out a document of a specific code system in a character form that conforms to the code system of the printer to be output, so that the character code system of the document to be output is changed to the character code of the printer to be output. Even if the document contents do not match the code system, the document contents can be printed out in an easily readable manner.

[Example] (1) Configuration In Fig. 1, 11 inputs the character code string of the document to be output, converts the character code string into a character code string handled by the printer to be output, and then outputs the character code string to the printer. This is an output control circuit that controls print output by supplying data to the host device, and receives a print control signal (PC), print data (CD) consisting of a character code string, etc. from the host device, and the printer that is the output target receives the kanji code. A signal indicating whether the printer is a kanji printer that handles kanji characters or a kana printer that handles kana codes is received as a code conversion designation signal (CC), and the print data (PD) of the character code string corresponding to the printer to be output is sent to the same printer. Output to. Reference numerals 12 to 15 are access-controlled by the output control circuit 11, respectively: 12 is an input buffer, 13 is an output buffer, and 14 and 15 are first and second code conversion circuits. The input buffer 12 stores print data (CD) consisting of a print character code string input from the host device, and the output buffer 13 stores code-based print data (PD) handled by the output target printer. Further, the first code conversion circuit 14 converts the 2-byte kanji code received from the output control circuit 11 into a 1-byte kana code (or kana code string) associated with the output control circuit 11 in advance. 11, and the second code conversion circuit 15 converts the 2-byte kanji/alphanumeric/kana code received from the output control circuit 11 into a 1-byte alphanumeric/kana code (or (kana code string) and sends it to the output control circuit 11.

16 is a printer placed under the control of the output control circuit 11;

(2) Function The output control circuit 11 stores the print data (CD) received from the host device in the input buffer 12, reads out the characters one by one in the input order, and the character code is a 2-byte Kanji character code. or alphanumeric/kana code expressed in kanji code, 1
Determine whether it is Kana code with a byte structure.

Here, when the printer 16 to be output is a kana code system, a code conversion designation signal (CC) specifying kana conversion is input to the output control circuit 11. According to this code conversion designation signal (CC), the output control circuit 11 determines whether the result of the code discrimination is 1.
When the character code is a byte-structured Kana code, the character code read from the input buffer 12 is stored as it is in the output buffer 13, and when the result of the code discrimination is a 2-byte-structured Kanji character code,
The character code read from the input buffer 12 is converted into a 1-byte kana code (or kana code string) by the first code conversion circuit 14, and the converted character code is stored in the output buffer 13. When the result of code discrimination is a 2-byte kanji, alphanumeric, or kana code, the character code read from the input buffer 12 is transferred to a 1-byte alphanumeric or kana code by the second code conversion circuit 15. (alphanumeric/kana code string),
The converted character code is stored in the output buffer 13. For example, for each kanji character code of ``Ha'', ``Mei'', the code is ``Ha'', ``Tsu'', ``Me'', and ``I''.
are converted into each kana character code string and stored in the output buffer 13.

The input buffer 12 performs such code conversion processing.
All of the print data (CD) stored in the printer 16 is followed, and the converted character codes stored in the output buffer 13 are sequentially converted into print data (PD) according to the synchronization signal (SC) from the printer 16.
It is output to the printer 16 as .

Further, when the printer 16 to be output is a Kanji code system, a code conversion designation signal (CC) designating Kanji conversion is input to the output control circuit 11.
The output control circuit 11 sequentially reads out the print data (CD) stored in the input buffer 12 according to the code conversion designation signal (CC) without going through the output buffer 13 and according to the synchronization signal (SC) from the printer 16. and output it to the printer 16 as it is.

In this way, each character code of a document to be printed out is selectively converted into print data of a character code string corresponding to the code system handled by the printer 16 to be output, and the print data is sent to the printer 16. Therefore, even if the character code system of the document to be output does not match the character code system of the printer to be output, the content of the document can be printed out in an easily readable state.

In the above embodiment, kanji are selectively converted to kana characters and printed out. However, for example, kanji can be selectively converted to Roman characters, or kana can be selectively converted to Roman characters and output. is also possible.

[Effects of the invention] As detailed above, according to the printing control device of this invention, in a system where the printer to be connected is not specified as either the Kanji code system or the Kana code system, the input buffer can be improved. means for reading stored character codes character by character and determining the code system thereof; and when the code system does not match the output target printer, the code read from the input buffer is read out in a predetermined manner according to the code system of the output target printer; It is equipped with a code conversion table for converting into codes or code strings that have been mapped to Even when the character code system of a document does not match the character code system of a printer to be output, the content of the document can be printed out in an easily readable state.
