Abstract

PURPOSE:To make the best use of respective advantages possible, by a method wherein both a host computer and a printer have respectively character generators and the former is used for high speed printing and the latter for low speed printing. CONSTITUTION:The data analysis part 2 to which character code data, the determination of high speed and low speed, etc. are given from a soft data analysis part 1, sends the character code data as they are to a printer 8 via a printer control part 4 for the designation of high speed printing and sends the character code data to an image editing part 3 for the designation of low speed printing. The editing part 3 develops the character code data to a character dot pattern with the character generator therein and sends it to the printer 8 via the printer control part 4. When the character code data are sent, the printer 8 converts them into a character dot pattern to be printed with the character generator therein and when the dot pattern is sent, the printer 8 prints it as it is. Therefore, the good printing at a low speed or the high speed printing inferior in quality may be selected.

Description

[Detailed Description of the Invention] [Summary] In a data processing device that has character generators in both the main computer and the printer, the character generator of the main computer is used for high-speed printing, and the character generator of the main computer is used for low-speed printing. This is a printing speed control method that uses the printer's character generator.

[Industrial application field]

In the present invention, when low-speed printing is specified by the operator, the main body system computer develops the dot pattern and sends the dot pattern of the character from the main body extra 3'F to the printer, and high-speed printing is specified. This relates to a printing speed control method in which a character code is sent to a printer, and the character code is developed into a dot pattern on the printer side.

[Prior art and problems]

Printers are generally equipped with a character generator, but the printer cannot draw ruled lines or freely change the spacing between characters. Therefore,
A character generator is also installed in the main body computer to generate character dot patterns on the main body side and transfer them to the printer side. The main unit is highly intelligent, so it can generate dot patterns of ruled letters, and the spacing between letters can be changed freely.

A system that uses only a character generator on the printer side has the advantage of high printing speed, but has the disadvantage that ruled characters and character spacing cannot be freely changed. In addition, a method in which a character generator is installed in the main body computer to generate character dot patterns on the main body side, and the dot patterns are sent to the printer has the advantage of being able to print high quality characters. , has the disadvantage of slow printing speed.

[Purpose of the invention]

The present invention is based on the above consideration, and an object of the present invention is to provide a printing speed control method that can perform high-speed printing or low-speed printing according to an operator's instructions.

[Means to achieve the purpose]

Therefore, in the printing speed control method of the present invention, in a data processing device comprising a main body computer having a character generator, a printer, and an input means, information indicating whether high-speed printing or low-speed printing is selected from the input means. In addition to configuring the computer so that it can input data into the main computer, if low-speed printing is specified, the main computer can convert the print character string passed from the application program into its own characters.
The generator converts the character into a dot pattern and transfers it to the above printer, and if high-speed printing is specified, the print string passed from the application program is transferred to the above printer in the form of character code data. It is characterized by the following structure.

[Embodiments of the invention]

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

FIG. 1 shows the configuration of one embodiment of the present invention.

In FIG. 1, 1 is a software data analysis section, 2 is a data analysis section, 3 is an image editing section, 4 is a printer control section, and 5 is a data analysis section.
Reference numeral indicates an application program, 6 a keyboard, 7 a display, 8 a printer, and 9 a main computer. The area within the dashed-dotted line indicates the software configuration within the main computer 9, and the portions 4 through 4 are programs or firmware. The software data analysis section 1
The data passed from the application program 5 is displayed on the display 7.
Based on the print formant information sent from [1
It is something to do. The print format information includes the number of page lines, maximum number of print digits, line feed pitch, number of line feeds, character pinch, paper type, high speed/low speed, etc. The software data analysis section 1 passes character code data, high speed/low speed classification, etc. to the data analysis section 2. The data analysis section 2
If high-speed printing is specified, the character code/data is sent as is to the printer 8 via the printer control unit 4, and if low-speed printing is specified, the character code/data is sent to the image editing unit 3.
send to The image editing section 3 has an internal character generator (not shown), and this character generator
Use a generator to expand character code data into character dot patterns.

The character dot pattern created by the image editing section 3 is sent to the printer 8 via the printer control section 4. The printer control unit 4 converts data and commands into a form that the printer 8 can understand and transfers the data and commands to the printer 8.

Data input from the keyboard 6 is displayed on the display 7 and then taken into the computer 9. When the printer 8 receives character code data, it uses a character generator (not shown) inside the printer to convert the character code data into a character dot pattern and prints it. . Also, when a character dot pattern is sent, it is printed as is.

FIG. 2 is a diagram showing an example of a display screen. When the interrupt key or control key on the keyboard 6 is pressed, a processing screen as shown in FIG. 2 (al) is displayed.

Figure 2 (If you press function key PF14 while the al processing screen is displayed, the image in Figure 2)
The processing screen will be displayed. Print information (
print format information). At this time, high speed or low speed is selected at the same time.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, high-speed printing or low-speed printing can be performed according to the operator's request. In other words, when the operator instructs low-speed printing, the printing speed is slow but the quality is good, and when the operator instructs high-speed printing, the printing quality is lower than when the slow-speed printing is instructed, but the printing is faster. Can print.
