Abstract

PURPOSE:To eliminate the need for providing a font data memory and a read mechanism in an output control device to reduce a cost, by a method wherein font data is read from a printer with a font data memory, edited, and outputted to an output device. CONSTITUTION:An output control device 20 connected to a printer 30 is provided with a font data read part 23. The printer 30 is provided with a font data transfer part 31. The font data read part 23 issues a character code 50 of output data together with a read instruction 60 to the printer 30. In the printer 30, the font data transfer part 31 reads corresponding font data 51 from a font data memory 11 and transfers it to the output control device 20. The transferred font data 51 is stored in a memory 22, thereafter being subjected to an edition processing for a proportional printing to be outputted to either the printer 30 or other output device such as a display part. In this manner, a font edition processing can be carried out without storing the font data 51 in the output control device 20, and the font data can be outputted to the other output device.

Description

[Detailed Description of the Invention] [Summary] The present invention relates to an output control method for glyph data, and aims to eliminate the need for a glyph data memory and its reading mechanism in an output control device. The output control device is provided with a glyph data reading unit that sends a character code to the printer along with a reading command, and causes glyph data corresponding to the character code to be transferred and stored in memory. A glyph data transfer unit is provided which reads the glyph data corresponding to the glyph data from the glyph data memory and transfers the glyph data to the output control device when the glyph data is received, reads the glyph data from the glyph data memory provided in the connected printer, edits the glyph data, and outputs the edited glyph data. Configure it as follows.

[Industrial application field]

The present invention relates to an improvement in a glyph data output control method.

Conventionally, the glyph (font) data of each character printed by an output device, such as a printer, is held by an output control device such as an electronic computer, and there is a method for giving it to the printer, and a glyph data memory (
There is a method in which a character pattern generator (CG) is included in the printer and the printer itself refers to it each time it prints.

The latter method, in which the printer owns the glyph data, was created because the former method requires a large amount of glyph data to be stored on the computer side and a large burden to transfer the glyph data to the printer.

However, for example, when performing proportional printing or displaying on a display unit that does not have glyph data, the computer still has to have the glyph data, and even the latter method does not reduce the burden on the computer, which is a problem. remains.

For this reason, there is a need for an output control method for glyph data that can be output processed without having glyph data on the computer side.

[Prior Art] FIG. 4 is an explanatory diagram of conventional output control, and FIG. 5 is an explanatory diagram of proportional printing.

FIG. 4 shows a block diagram of the computer system. When data processed by the computer 1 and stored in the file 3 is output to the printer 2, and when data is printed using the glyph data provided by the printer 2. edits the character code according to the output format and outputs it to printer 2,
The printer 2 side refers to the glyph data memory 11 based on the received character code, develops glyph patterns in, for example, a line buffer, and prints them in line order.

This glyph data memory 11 is a read-only memory ROM in which JIS 1st level, 2nd level, and user-defined characters are recorded, and all glyphs are, for example, 24
Since it is composed of a fixed number of dots such as 24, when characters with a narrow width are printed, the spacing between the characters appears wide, making it difficult to expect uniform printing.

In order to eliminate such defects, proportional printing is performed in which the white part is trimmed according to the character width, but this is done by electronic calculation [1 side checks the actual character width using glyph data and controls the character spacing. It determines how many lines can be printed on one line, performs editing processing, and outputs to a printer.

Figure 5 shows an example of proportional printing.
This is an example of cutting down the white parts on the left and right sides of .

In order to perform such proportional printing, it is necessary to have a character shape data memory 6 on the computer 1 side.
Also, when outputting to the display section, this glyph data memory 6 is referred to and output.

[Problem that the invention seeks to solve]

If the electronic computer, which is the output control device, has glyph data, the burden of recording rarely used kanji, user-defined characters, etc. will be heavy, so instead of having the glyph data in the computer, use the glyph data provided by the printer. If the configuration is such that printing is carried out, there is a problem that proportional printing or output to the display section cannot be performed.

[For production]

The glyph data reading unit 23 receives a read command (READ command) 6
0 and the character code 50 of the output data to the printer 30.
In the printer 30, the glyph data transfer unit 31 reads the glyph data 5I corresponding to the glyph data memo January 1 and transfers it to the output control device 20.

The transferred glyph data 51 is stored in the memory 22, and thereafter subjected to editing processing for proportional printing and output to the printer 30 or to an output device such as a display unit.

As described above, the glyph can be edited without having the glyph data 51 in the output control device 20, and the glyph data can be output to another output device.
