JPH04220367A - High speed drive apparatus of language corresponding printer - Google Patents

Abstract

PURPOSE:To prevent the lowering of a printing speed generated when the alteration of a font is frequently performed and to solve such a problem that an unregistered font is not usable in a language corresponding printer. CONSTITUTION:The appearance frequency of the characters in document data is measured and the font of characters high in appearance frequency is registered in the memory of a printer. Further, characters are distributed corresponding to fonts and the distributed characters are sent out to the printer at every fonts. By this constitution, even when a font is altered and an unregistered font is used, high speed printing can be achieved.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for driving a language-compatible printer at high speed.

0002

2. Description of the Related Art When driving a language-compatible printer, document data stored in a storage medium such as a magnetic disk is read out by a word processor or a personal computer, and the retrieved document data is decoded and sequentially provided to the printer, mainly for printing. It drives a language-compatible printer that performs the following functions.

However, simply sending the decoded document data to the printer one after another requires that the fonts of each typeface to be used be registered in advance in the printer's memory, resulting in the disadvantage that unregistered fonts cannot be used. There is.

[0004] Furthermore, if the font is changed frequently,
The font registered in the printer's memory must also be changed, which has the disadvantage of reducing printing speed.

[0005]

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to solve the problem that printing speed decreases when fonts are changed frequently.

[0006] At the same time, it is an attempt to solve the problem that unregistered fonts cannot be used.

[0007]

[Means for Solving the Problems] The present invention measures the frequency of appearance of each character in document data, and registers the font of the character with high frequency of appearance determined based on this in the memory of a printer. Each character is distributed according to the font, and each distributed character is sent to the printer for each font,
This allows for faster printing even if the font is changed or an unregistered font is used.

[0008]

[Operation] Unregistered fonts can be used freely, and printing can be performed at high speed even if the font is changed frequently.

Embodiment FIG. 1 is a block diagram showing an embodiment of the present invention, including a document data decoding means (hereinafter referred to as DEC) 1, a frequency of appearance measuring means (hereinafter referred to as FCT) 2, and a font distribution means (hereinafter referred to as FCT) 2.
SDB) 3, character output means (hereinafter referred to as CAS) 4, ward code, character type appearance frequency table (hereinafter referred to as CCF) 5, and
The font registration means (hereinafter referred to as FRG) 6 constitutes a document processing device (hereinafter referred to as WPR) 7 such as a word processor or a personal computer, and the WPR 7 stores a document file (hereinafter referred to as WFL) on a recording medium such as a magnetic disk. 8 and a language compatible printer (hereinafter referred to as a PRT) 9, and drives the PRT 9 with document data taken out from the WFL 8.

[0010] Here, the document data read from WFL8 is decoded by DEC1, the frequency of appearance of each character is measured in FCT2, and this result is
Data are counted by S ward code, character type, and font.

[0011] The output of FCT2 is SDB3 and CCF
5, CCF5 creates a table of the frequency of appearance for each ward code and character type, and FRG6 selects a font for characters with high frequency of appearance according to the contents of this table, and stores this font in the memory of PRT9. register.

On the other hand, in the SDB 3, each character is classified and distributed by font, and the CAS 4 extracts each of the distributed characters for each font and sends them to the PRT 9.
As a result, the PRT9 is driven.

Therefore, the PRT 9 sequentially prints each font using the fonts registered in its own memory, and can print in a desired font at high speed even if the font is changed.

[0014]

As is clear from the above explanation, according to the present invention, the appearance frequency of each character included in document data is measured, and the font of the character with high appearance frequency is registered in the memory of the printer. By distributing each character in the data according to the typeface and sending each distributed character to the printer for each typeface, it is possible to use unregistered fonts freely, and the typeface can be changed frequently. Since printing is also performed at high speed, a remarkable effect can be obtained in driving a language-compatible printer.
