Description

Method for setting default font in image forming device}

The present invention relates to a font setting method of an image forming apparatus, and more particularly, to a font setting method for printing a document created by an application program having a single font in a font desired by a user.

In general, Microsoft's word programs, and document authoring programs like Hangah Hangul, have more than a dozen different fonts (for example, Gulim, Ming and Gothic). These fonts are installed when the document creation program is installed on a host such as a computer, and the user selects a font suitable for his or her taste, creates a document according to the selected font, and transmits it to an image forming apparatus such as a printer. You can print the document with. On the other hand, document writing programs used in Linux or DOS-based operating systems usually use only one font (for example, Myungjo or Arial). Document authoring programs such as the VI editor in the Linux operating system, or the ultra editor often used by computer programmers in the Windows operating system, can only use one or two fonts in the document. Can be. Such a program is faithful to the inherent purpose of writing a document and writing a program, and does not consider user convenience greatly. Conventionally, in order to solve such a problem, a method of setting a font by downloading a font to a printer has been disclosed. To download fonts to the printer, you need to obtain a separate program and file type font for downloading. If one of them is insufficient, you should use one or two fonts set in the printer. Accordingly, the present applicant is to provide a method for setting a reference font in the image forming apparatus to print a document created by a document creation program having a few internally embedded fonts in a font desired by a user.

As described above, the present invention is to provide a method for setting a reference font that can apply a font desired by a user to various document creation programs.

According to the present invention, in the font setting method of the image forming apparatus having at least one font, the step of setting the print data set and transmitted in the driver program provided in the host as a reference font, the reference Receiving a font from the host, and applying the reference font to the print data transmitted from the host to print.

The setting of the reference font may include creating a document in a predetermined font in the host, converting the document into print data by the driver program, and transmitting the converted print data to the image forming apparatus. It is preferred to include the step.

The step of creating the document is preferably created by a document creating application provided in the host.

The printing may include extracting a font from print data that is set as a reference font and applied to the image forming apparatus, and printing the print data transmitted from the host in correspondence with the extracted font. desirable.

The extracted font is preferably stored in a memory provided in the image forming apparatus.

Hereinafter, the present invention will be described in detail with reference to the drawings.

As shown, according to the present invention, the reference font setting method includes selecting a file (1.DOC) in which a font desired by a user is embedded in the host computer 100, and providing the file to the host computer 100. The program is transmitted to the image forming apparatus 200 through the program. The image forming apparatus 200 analyzes the file transmitted by the driver program to extract the font, and when the print data corresponding to the same letter, number and symbol as the extracted font is applied from the host computer 100, the extracted font Apply to print. At this time, a user-created file (1.DOC) is created by a word writing program of Microsoft Corp. or a document writing application program having various fonts embedded therein, such as Hangul Hangul. That is, a file (1.DOC) is created through a document creation application program in which a font desired by a user is embedded, and the created file is imaged through a driver program installed to drive the image forming apparatus 200 in the host computer 100. By applying to the forming apparatus 200 to set as a reference font, the user can print a document created by a document creation application program such as VI Editor or Ultra Editor in a desired font.

FIG. 2 shows an example of creating a file (1.DOC) shown in FIG.

As shown, the file (1.DOC) runs a document creation application (eg, Word, Haeah Hangul, etc.) with the font desired by the user, and prints the font desired by the user in the driven document creation application. Type letters, numbers, and symbols and save it as a file. For example, write alphabets, Korean consonants, Korean vowels, and numbers, such as 1 to 0, a to z, a to ㅎ, and ㅏ to ㅣ, and save the written characters, numbers, and symbols to a file (1.DOC). do. The file (1.DOC) includes letters, numbers, and characters to be printed in the image forming apparatus 200 when the document is created and printed in a document creating application (for example, an ultra editor, a VI editor, etc.) that the user wants to use. Letters, numbers, and symbols for symbols are entered. In the figure, only letters and numbers are shown, but in addition, various characters (characters in various forms such as half-width characters, embossed characters, ruled lines characters) and symbols may be included.

3 is a schematic block diagram of the image forming apparatus 200 illustrated in FIG. 1.

The illustrated image forming apparatus 200 is a block diagram of a laser printer, and includes an interface unit (I / F) 210, an image processing unit 220, an engine control unit 230, and an engine unit 240. .

The interface unit (I / F) 210 interfaces between the host computer 100 and the image processing unit 220. In general, the host computer 100 may be connected to the image forming apparatus 200 through a parallel port of the IEEE1284 standard, a universal serial bus (USB), and a LAN.

The image processor 220 converts the print data transmitted from the host computer 100 into data of a bit map method, and transmits the data to the engine controller 230. The engine control unit 230 is a bitmap printing data transmitted from the image processing unit 220 and mechanical units such as the fixing unit 241, the developing unit 242, and the LUS 243 that constitute the engine unit 240. Control the drive. In general, the engine controller 230 uses an application specific integrated circuit (ASIC) that generates pulses for driving a motor or an actuator constituting the engine 240 based on the bitmap data.

Preferably, the image processor 220 includes a flash ROM 221, a processor (CPU) 222, and a RAM 223. Flash 221 is a control program for controlling an image forming apparatus, an operating system, and print data applied through an interface unit (I / F) 210 from a host computer 100 in bitmap format. And a conversion program for converting to. The processor 222 generally controls the image forming apparatus 200, executes a control program stored in the flash ROM 221, or converts print data into a bitmap format. In addition, the print data sent by setting as a reference font in the driver program installed in the host computer 100 is not deleted when stored in the RAM 223 or the flash ROM 221, and the reference font is deleted. Extract fonts from embedded print data.

The RAM 223 provides temporary storage space required by the processor 222 to convert print data into a bitmap format or to drive a control program. The RAM 223 may store print data designated as a reference font.

The illustrated driver program includes a document option 110a, a print quality option 120a, and a reference font setting option 130a. Document option 110a is an option to set the number of pages printed per unit paper. If this number is high, multiple pages are printed on a unit paper (for example, A4 paper). Printed page by page. The print quality option 120a represents an option for adjusting the amount of toner (or ink) printed on the paper. The reference font setting option 130a indicates an option for transmitting the file 1.DOC selected by the user to the image forming apparatus 200. In the figure, a file (1.DOC) is selected. The reference font setting option includes a key 131a for finding a desired file, a selection key 132a for selecting a found file, and a cancel key 133a.

5 illustrates a preferred embodiment of a method for setting a reference font of the image forming apparatus according to the present invention.

First, the user drives a document creation application program having a font desired by the host computer 100 and types letters, numbers, and symbols through the driven document creation application program (S300). Next, the document created by the user is stored in the form of a file (S310), and the driver program installed in the host computer 100 is driven. The user selects a file (1.DOC) having a reference font from the driver program, and the driver program converts the file (1.DOC) selected by the user into print data in the form of a print command and data to form an image forming apparatus. S200 is transmitted to (S320). The processor (CPU) 222 of the image forming apparatus 200 temporarily stores a file (1.DOC) designated as a reference font in a RAM (223) and stores the file (1.DOC) in a temporary stored file. The RAM 223 is controlled so that the print data is not deleted. The processor 222 analyzes the print data stored in the RAM 223 and analyzes each character included in the print data (for example, a to z, 1 to 0, a to ㅎ, ㅏ to ㅣ etc.). Extract it (S330) and store it in the RAM (RAM) 223. At this time, the processor (CPU) 222 may store information on each character (for example, a to z, 1 to 0, a to ㅎ, ㅏ to ㅣ, etc.) stored in the RAM 223. The RAM 223 is controlled so as not to be deleted from the 223.

Next, when print data for a file not set as a reference font is applied from the host computer 100, the image forming apparatus 200 may store each character (for example, a to z,) stored in the RAM 223. 1 to 0, a to ㅎ, ㅏ to ㅣ and the like are compared with the print data, and the same characters (or numbers or symbols) are applied to the characters stored in the RAM (RAM) 223 for printing (S340). ). That is, a document written by a user through a writing application program such as VI Editor or Ultra Editor can be stored in the RAM 223 (for example, a-z, 1--0, a-h, b-h, etc.). ) To be printed, and the font set in the characters (for example, a to z, 1 to 0, a to ㅎ, ㅏ to ㅣ etc.) stored in the RAM 223 is applied. Accordingly, the user can print and view a document created by the user by applying a desired font in addition to the few fonts set in the document creation application program used by the user.

As described above, the present invention can allow a user to print a document created by a document creation application program having fewer embedded fonts in a font desired by a user.
