Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printing device, and more particularly to a printing device having eight printing character control mechanisms in an information processing peripheral device or the like.

[Conventional technology]

Conventionally, in printing devices that have a print character control mechanism and can change the character font and character font attributes (size, etc.) of the characters to be printed, when changing the character shape of the character to be printed, it is necessary to change the character shape. Each time, the character font information corresponding to the changed glyph shape is transferred from the computer etc. to the printing device,
It was necessary to change all character font information stored within the printing device to one that corresponds to the changed glyph shape.

So, for example, if the first page is printed in Gothic font and the second
When printing pages in Mincho font, all character font information compatible with Gothic fonts is transferred to the printing device before printing the first page, and Mincho font information is transferred before printing the second page. It was necessary to transfer all character font information corresponding to the font to the printing device.

[Problem to be solved by the invention]

Conventionally, as mentioned above, every time the glyph shape of a character to be printed was changed, all the character font information corresponding to the glyph shape to be printed had to be transferred to the printing device. If the character shape is changed during printing, printing performance will be degraded due to the time required to transfer the character font information.

An object of the present invention is to improve printing performance when printing by changing the shape of characters.

[Means to solve the problem]

In order to achieve the above object, the present invention includes character code data that specifies characters to be printed, character specification information that specifies characters whose glyph shape is to be changed, and character font information change data that includes glyph designation information that indicates the glyph shape after the change. a data reading means for receiving mixed print data; a character font information storage means for storing character font information; and a method for determining whether the data received by the data reading means is character code data or character font information change data. a character font information analysis means for analyzing the data determined by the data determining means to be character font information change data to obtain character designation information and glyph designation information; and the character font information storage. The character font information analysis means selects only the character font information corresponding to the character whose character shape is instructed to be changed based on the character designation information obtained by the character font information analysis means, out of the character font information stored in the character font information analysis means. character font information updating means for updating according to the obtained glyph designation information; and character font information stored in the character font information storage means and the data determined to be character code data by the data determining means. The printer is equipped with a printing means for printing.

[For production]

The data determining means determines whether the data received by the data reading means is character code data or character font information change data. The character font information analysis means analyzes the data determined to be character font information change data by the data discrimination means, and the character font information update means updates data to the character font information storage means based on the analysis result of the character font information analysis means. Only the character font information corresponding to the character whose character shape is instructed to be changed by the character designation information in the stored character font information is updated according to the character shape designation information. The printing means performs printing based on the data determined to be character code data by the data determining means and the character font information stored in the character font information storage means.

〔Example〕

Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, which is composed of a printing device 10, a computer 21, and a print data storage file 22. As shown in FIG. The printing device 10 has a data reading means 11 that receives data from the computer 21.
, a data determining means 12 for determining whether the received data is character font information change data or character code data, a character font information analysis means 13 for analyzing the character font information change data, and a character font information updating means. 14, character font information storage means 15, and page unit printing means 16.

FIG. 2 is a diagram showing an example of the contents of the print data storage file 22. As shown in FIG. Referring to the figure, the print data storage file 22 contains a series of print data..., 31°32, 33
．． 34. ... is stored. The print data 31 of the first page printed first is the character font information setting data (
This is data that specifies the type of character font information to be stored in the character font information storage means 15 at the start of printing, for example, a character font name given corresponding to the combination of character font and attribute is used) 35 is printed. The print data 32 on the second page is composed of character code data 36 that represents characters numerically, and the print data 32 on the second page is character font information change including the character code of the character whose font is to be changed, pattern data corresponding to the changed font, and attribute data. Consisting of data 37 and character code data 38, print data 33 on the third page
is composed only of character code data 39, and the print data 34 of the fourth page is composed of character font information change data 40 and character code data 41.

Next, the print data stored in the print data storage file 22..., 31.32.33.34. The operation when printing according to the following will be explained. The computer 21 sequentially reads the print data stored in the print data storage file 22 starting from the first page. When the character font information setting data 35 of the print data 31 of the first page is read, the computer 21 stores the character font information specified by this character font information setting data 35 in the character font information storage means 15, and thereafter stores the print data. Data read from file 22 36.37. ... are sequentially added to the printing device 10. Data added to printing device 10 36.37. ... is received by the data reading means 11, and the data determining means 12 determines whether the data received by the data reading means 11 is character code data or character font information change data, for example, by embedded in each data. The determination is made based on the identifier that is present.

When the data reading means 11 determines that the received data is character font information change data,
The data discriminating means 12 adds the above data to the character font information analyzing means 13. When the character font information analyzing means 13 receives the character font information change data from the data discriminating means 12, it analyzes the character of the character whose font is to be changed. A code, a character pattern indicating the character shape after the character shape change, and attribute data are obtained and added to the character font information updating means 14.

The character font information updating means 14 updates only the character pattern corresponding to the character specified by the information added from the character font information analyzing means 13 to the character font information analyzing means 1.
Change based on the information added from 3. That is, only part of the character font information stored in the character font information storage means 15 is changed.

Further, when the data determining means 12 determines that the data received by the data reading means 11 is character code data based on the identifier, the 0 page unit printing means 16 adds the received data to the page unit printing means 16. When the data is added, the character font information stored in the character font information storage means 15 is referred to and printing is performed on the print medium.

Therefore, now, for example, character font information change data 37
is an instruction to change the shape of the character rAJ to rAJ, and the character font information change data 40 is the character rAJ.
Assuming that the instruction is to change the character shape of AJ to rAJ, the print results for pages 1 to 4 when printing the print data shown in Figure 2 are 51 to 5 in Figure 3, respectively.
4.

〔Effect of the invention〕

As explained above, the present invention dynamically changes only the character font information corresponding to the character specified by the character font information change data of the character font information stored in the character font information storage means. Therefore, when changing the font of a character to be printed, all the character font information corresponding to the character whose font is to be changed can be transferred to the printing device, so every time the font of a character to be printed is changed, all the font information This has the effect of significantly improving printing performance, such as printing speed, compared to conventional devices, which require data to be transferred to a printing device.
