[Detailed Description of the Invention] [Summary] A color display display format is provided for a color printer device that realizes color printing by overprinting three colors and has a black printer ribbon in addition to three colors of printer ribbons. When transferring data and performing color printing, the default color specified characters and ruled lines that are displayed in green on display devices are printed in black to improve print quality and speed up printing. It is something.

[Industrial application field]

The present invention provides a color printing control method in which characters and ruled lines specified in a default color are printed in black when a character string displayed on a color display screen is printed by a color printer device. It is related to.

[Prior art and problems]

In a color display device, when a default color is specified, the characters are displayed in green on the display screen, and the ruled lines are also displayed in green on the display screen. BACKGROUND ART Data in a color display format is sent to a color printer, and character strings and the like displayed on the color display screen are printed by the color printer. In the conventional color printing control system, characters and ruled lines specified by default color are printed in green. However, in a color printer, two colors of green are printed overlapping each other, which doubles the printing time and may cause color misregistration.

[Purpose of the invention]

The present invention is based on the above consideration, and an object of the present invention is to provide a color printing control method that makes it possible to print character strings on a display screen in an easy-to-read manner and efficiently.

[Means for solving problems]

Therefore, the color printing control method of the present invention includes a color display device, a color printer device having three color printer ribbons and a black printer ribbon, and a color printer device that controls the color display device and the color printer device. In the data processing system, when printing characters and ruled lines on the screen of the color display device with the color printer device, the processor described in - above prints the characters and ruled lines specified by the default color in black. The present invention is characterized in that it is configured to control the color printer device to cause it to print.

[Embodiments of the invention]

Hereinafter, the present invention will be explained with reference to the drawings. FIG. 1 is a diagram showing an example of a hardware configuration for implementing the present invention. In FIG. 1, 1 is a processor, 2 is a display memory, 3 is a printer buffer, 4 is a display control device, 5 is a color display, 6 is a printer control device, and 7 is a color printer. The processor 1 controls the entire system by executing a control program in a ROM (not shown). The display memory 2 stores display data and display attribute information. The printer buffer 3 stores one line of print data. The display control device 4 is
Color and color according to commands sent from processor 1.
This is to control the display 5. The printer control device 6 also controls the color printer 7 based on the command sent from the processor 1. It is for wholesale. Color Printer 7 II is a dot-ma-wax impact type printer, which has a yellow printer ribbon, a magenta printer ribbon, a cyan printer ribbon, and a black printer ribbon.

FIG. 2 is a diagram showing the configuration of the display memory. In FIG. 2, 8 indicates a character plane, and 9 indicates a flag memory. The display memory 2 has a character plane 8 and a flag memory 9.

The character plane 8 is a dot pattern memory and has the size of one screen, in which character strings to be displayed on the display screen are written in dot matrix format. The flag memory 9 has an information storage area corresponding to the character frame on the display screen, and the information storage area corresponding to the character frame in the i-th row and column contains color information for the character in the i-th row and column. , ruled line information, etc. are stored.

FIG. 3 explains the printer buffer,
The printer buffer 3 has the size of one line, and a character string to be printed by the color printer 7 is written in a dot matrix format.

FIG. 4 is a diagram showing the relationship among screen display, character plane, flag memory, and print result. In the example shown, the characters "GR" are displayed in green on the screen, and an underline is attached to these character strings. Also, the default color is specified for the character string "DEFF". These character strings are also marked with an underline.If you specify the default color, the characters will be displayed in green on the display screen, and the ruled lines will also be displayed in green on the display screen. In the character plane, character strings "GR" and "DEFF" are stored in a dot matrix format. In the flag memory, there is information indicating that the letter "G" is green with an old underline (lower ruled line), and that the letter "R" is green with an H underline (lower ruled line).
The information indicating that the character is underlined, and the character ")" is the default color specification, and the character ")" is the default color specification, and the character ")" is the default color specification. If the color printing control method of the present invention is implemented under such conditions, the character string "GR" will be printed in green, and the default color "" will be printed. The character string "def" is printed in black, and the ruled lines are also printed in black.

Note that there are several types of ruled lines, such as an upper ruled line, a lower ruled line, a right ruled line, a left ruled line, etc.

FIG. 5 is a diagram illustrating the display 1174 screen printing process performed by the processor. First, the yellow mark [i11 processing is performed. First, instruct the printer control device 6 to select the yellow printer ribbon.

Next, the color information and ruled line information in the flag memory corresponding to one line of character strings to be printed are read, and it is checked whether there is anything to be printed in yellow. If it exists, the character to be printed in yellow is extracted from the character plane 8 and written to the corresponding position in the printer buffer 3, and the printer startup instruction and the data in the printer buffer 3 are sent to the printer control device 6. After the yellow printing process is performed, a magenta (dark pink) printing process is performed in the same manner, and then a cyan (blue) printing process is performed. For example, green printing is accomplished by first printing yellow, and then overprinting cyan.

After performing the cyan printing process, the processor 1 instructs the printer control device 6 to select a black printer ribbon. Next, the color information and ruled line information in the flag memory corresponding to one line of character strings to be printed are read, and it is checked whether a default color designation or ruled line information exists. If there is a character designated with a default color, the character designated with the default color is extracted from the character plane 8 and written to the corresponding position in the printer buffer 3. After writing characters specifying the default color into the printer buffer 3, a ruled line pattern specified by the ruled line information is created and developed by ORing with the corresponding position in the printer buffer 3. After writing the ruled line pattern into the printer buffer 3, a printer startup instruction and the data in the printer buffer 3 are sent to the printer control device 6. After color printing for one line is completed, a line feed instruction is sent to the printer control device 6.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, when printing the screen of a color display device, since the characters and ruled lines specifying the defmelt color on the display screen are printed in black, easy-to-read printing is achieved. At the same time, the remarkable effect that the printing speed is improved is obtained.
