Description

[Detailed Description of the Invention] Technical Field The present invention relates to a printing system, and in particular, has a character pattern data file in which predefined character information and character patterns corresponding to the character information are registered, and which corresponds to input character information. The present invention relates to a printing system that reads a character pattern from a character pattern file and prints it.

BACKGROUND ART Conventionally, in this type of printing system, a file is provided in which character information and character patterns corresponding to the character information are registered in advance. When information about characters to be printed is sent from the host device, the corresponding character pattern is read from the file and printed.

However, if the character information sent from the host device is undefined, the corresponding character pattern does not exist in the file, and there is a drawback that the printed character is not guaranteed, such as a space in that part. there were.

OBJECTS OF THE INVENTION The present invention has been made to solve the above-mentioned conventional drawbacks, and its purpose is to provide a printing system that guarantees printing results even for undefined characters.

Composition of the Invention The printing system according to the present invention has a character pattern data file in which predefined character information and character patterns corresponding to the character information are registered, and the character pattern corresponding to the input character information is registered in the character pattern. A printing system that reads data from a data file and prints the data, the system associates undefined character information with a predetermined character pattern among the character patterns in response to a registration command from an external device, and prints the data in the character pattern data file. It is characterized by having undefined character registration means for registering.

Example Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of a printing system according to the present invention. In the figure, the printing system of this embodiment is an editing means 1 of alternative character information for undefined characters.
and registration means 2 for registering alternative character information for undefined characters in the character pattern data file for the main language printer, and storage means 3 for storing alternative character information for the undefined characters in the wooden printer. A computer 10, a data file 4 of character patterns for Japanese printers, and a printing means 6 for printing alternative characters when printing undefined characters.
and a Japanese printer 5 including an undefined character management area 7.

Editing means 1 of substitute character information for undefined characters has a function of editing the character code of the information indicating the font of the character to be printed, together with the code of the character to be substituted for printing when the character is undefined. have It also has a function of registering the edited alternative character information in the data file 4 of character patterns for Japanese printers by means 2 of registering alternative character information for undefined characters in the data file 4 of character patterns for Japanese printers. .

A storage means 3 for storing alternative character information for undefined characters in the 11 Japanese printer stores undefined characters when expanding character dot-bang information from a character pattern data file 4 for Japanese printers onto the memory of the Japanese printer 5. It has a function of storing alternative character information in the alternative character management area 7 for.

The printing means 6 which performs substitute character printing when printing an undefined character has a function of printing a substitute character when a target character dot pattern does not exist when printing a character.

The printing system of this embodiment uses the above editing means 1, registration means 2, and storage means 3 to register undefined characters in association with other characters, that is, alternative character patterns, during system operation.

FIG. 2 is a flowchart showing the processing procedure in the editing means 1 for substitute characters for undefined characters.

First, the character type (number of points, etc.) and character code of the undefined character, and the code of the corresponding substitute character are acquired (step 21).

Next, it is checked whether the acquired codes of undefined characters and alternative characters are within a predefined valid character range (step 22). If it is outside the legal range of characters, it will be processed abnormally (
Perform step 23).

On the other hand, if the iIE is a valid character range, edit the character code of the information indicating the font of the character to be printed, along with the code of the character to be printed as an alternative if that character is undefined. hold (step 24).

FIG. 3 is a flowchart showing the processing procedure in the registration means 2 for registering character patterns for Japanese printers in the data file 4 of substitute character information for undefined characters.

First, in step 31), undefined character information and alternative character information, which are held as a pair, are transferred to a buffer in a format according to the records of data file 4 of character patterns for Japanese printers. Necessary information τj is added (step 32).

After that, preparations are made so that records can be output to data file 4 of character patterns for Japanese printers (step 33), and records of completed alternative characters are output to data file 4 of character patterns for Japanese printers. (Step 34) FIG. 4 is a flowchart showing the processing procedure in the storage means 3 for storing alternative character information for undefined characters in the Japanese printer.

First, all character dot pattern data of the type of character to be printed is extracted from the character pattern data file 4 for one-track printer (step 41). All of the extracted character dot pattern data is developed and stored in the memory of the Japanese printer 5 (step 42).

At that time, if an alternative character record exists in the pig file 4 of the character pattern for Japanese printers (step 43), the undefined character code on the alternative character record and the alternative character code corresponding to that code are Each character information is developed in the alternative character information storage memory in the Japanese printer (step 44).

On the other hand, if it does not exist in the data file 4, the process ends (steps 43→45).

FIG. 5 is a flowchart showing the processing procedure in the printing means 6 for printing substitute characters when printing undefined characters.

When printing a character in the Japanese printer 5, it is checked whether dot pattern data of the character to be printed exists in the memory (step 51).

If it exists, perform normal character printing (step 52)
. On the other hand, if it does not exist, it is further checked whether there is alternative character information corresponding to the character to be printed (
Step 53).

If the alternative character information does not exist in the memory, abnormality processing is performed as an invalid character printing (step 54). On the other hand, if alternative character information exists in the memory, a dot pattern of the corresponding character is developed from the alternative character code at the printing position (step 55). For undefined characters, substitute characters are printed instead.

Next, a specific example of registering undefined characters in the data file 4 will be described.

Assume now that the character to be printed is "■" and its dot pattern is not stored in the data file 4, that is, it is an undefined character. Therefore, even if you try to print it as is, printing is not guaranteed and the result will be "" (space).

Therefore, by registering the undefined character "■" and other characters in association with each other as described above, a substitute character will be printed. For example, if this undefined character "■" and "1" are associated and registered, "1" will be used instead of "■".
will be printed.

Furthermore, assuming that rIJ is also an undefined character, if this undefined character rIJ and "1" are registered in association with each other, "]" will be printed instead of rIJ.

Further, it may be registered in association with the kanji characters "-" and "ichi", but only one substitute character can be used for one undefined character.

DETAILED DESCRIPTION OF THE INVENTION As described in detail, the present invention registers arbitrary alternative characters in association with undefined characters, so that when printing with a Japanese printer, characters to be printed are undefined. However, there is no guarantee of printing, and the effect is that characters are automatically printed in place of the characters.
