Abstract

PURPOSE:To print by a picture memory for one line by taking out print data for 1 line from a buffer memory and developing the data to a dot image data with one line as a unit. CONSTITUTION:Data for 1 page consisting of character data 2, graphic data (vector data) 3 and attribute data 4 including print position information from an inputting section are stored in a buffer memory 5. A page controlling section 12 controls and derives information of data of line to be developed, the size of blank form 6, line pitch etc. on the space of imaginary blank form basing on attribute data 4. A developing process section 7 analyzes character data 3 according to indicative data of line position etc. from the page controlling section 12, and enlarges, rotates and inverts dot image data of character font read out from a character generator 10, and develops dot image data that can be contained in a line in a storage section 8. A printer controlling section 13 outputs dot image data for 1 line of the storage section 8 to a printer1 in line unit.

Description

[Detailed Description of the Invention] [Summary] 5. Case 2 of printing and outputting information currently consisting of characters and figures
Normally, it is necessary to prepare an image memory for one page, but the present invention is a printing method that allows printing with one line of image memo + 1.

[Industrial application field]

The present invention is an improved printing method for printing characters and figures.
A: Reduce the print memory capacity attached to the printer,
It is hoped that measures will be taken to reduce the price of splitters.

[Conventional technology]

A conventional example will be explained with reference to the drawings. FIG. 6 is a block diagram illustrating a conventional example.

When printing a mixture of characters such as Nagiji characters and isomorphic characters on one page, input data for one page consisting of character data 1, graphic data (vector data) 2, and attribute data 3 from input section 1. . These input data are stored in bar 7 memory (
5, which has a capacity of one page. Note that the nationality data 3 is position information that specifies the printing position on the paper 6.

The processing unit 7 sequentially takes out the input data in the buffer memory 5 and starts expanding it into the storage unit (image memory) 8. Character code 2 is obtained by extracting character pattern data 9 corresponding to the character from character generation L510. The memo 11 position specified by the attribute data 3 is stored in the storage section 81C. Further, as for the figure, image data of a dot configuration is stored in the storage unit 8 based on the vector data 2. As a result, a dot-structured character and graphic image pattern consisting of pit information is developed in the memory B8 as shown in the figure.

The image data in the storage section 8 is sent to the printer 11,
Paper 6) C is printed out.

The expansion processing unit 7 expands the data into dot-structured data 14 in line units and stores it in the storage unit 8, and the printer fIIIllllU unit 13 sends the line unit data 14 to the printer 11 and prints it on the paper 6. Print KM next.

〔Example〕

Hereinafter, the present invention will be explained with reference to the drawings. Figure 2.

4 and 5 are block diagrams explaining an embodiment of the present invention, and FIG. 3 is a flowchart explaining an embodiment of the present invention. , has a memory capacity for one line. That is, according to the present invention, one page of information consisting of N lines can be printed using one line's worth of image memory.

In Figure 2, character data l is input from input section l.

When data for one page consisting of graphic data (vector data) 2 and attribute data 3 is input, these input data are stored in a buffer memory (having a capacity for one page) 5Kl@. The procedures performed by the page management section 12 and the expansion processing section 7 will be explained below according to the flowchart IIN in Figure 3. The block diagrams shown in FIG. 4 and FIG. 5 are also used.

■ The page management unit 12 prints which line of data will be developed (and printed) in the virtual space (=virtual paper space) shown in the brush 4 diagram (al) based on the attribute data 3 in the buffer memory 5. Instruct the processing section to equalize the size of the paper 6.

Upon receiving this, the expansion processing unit 7 performs character addressing (positioning in virtual space). That is, character data consisting of kanji codes (codes representing characters such as A3A3H) and collateral codes (line breaks/column pitches, attributes, etc.) are analyzed, and the page management unit 12
The physical position is determined by determining whether the character will fit in the line position specified by .

For example, the case where the page W science department instructs to develop the third line will be explained using Figure 4 (blK). Figure 4 (b) shows the physical area (1 line)
shows. As shown in the diagram, the kanji characters ``A'' and ``I''.

This is print information that spans the third and fourth lines.

In this way, if the kanji on the fourth line is a vertically enlarged character, the upper half of the kanji will be on the third line, so it will be determined that it is a target character for expansion, and the base point (address) of each character font will be set.
In other words, the upper half of the vertically enlarged characters of the kanji "A" and "I" in the third line will be expanded, so the pattern of the famous character will be created. , which means that we have determined where the character box will be placed.

■ Next, the expansion processing unit 7 converts the vector data 3 into an image □Vector data string expressing a pie chart or line graph (information such as where to draw a line, what pattern to use for hatching, etc. Column) is analyzed, it is determined whether circle or line data should be developed at the row position specified by the page management f[112, and the Dovto Image VC is developed.

For example, as shown in Figure 4, when a part of the %n0th line graph (indicated by diagonal lines) is displayed, the m, pattern, etc. of this part are converted into dot image data.

■ Furthermore, the development processing B7 performs image processing of the character data.The character assignment of the 0 item is based on the information obtained in the processing, and the characters (for example, "A") are approximated from the character generator 10.
Extract the character pattern 9 of the character pattern 9 (and "Italy"), enlarge it (stretch the bits), designate rotated vertical writing, etc.), reverse @ (invert the pits), etc.

Therefore, dot image data as shown in FIG. Tdl in the storage section 8Kft%w14 is developed.

When the above processing is completed, the printer wJ section 13 prints image data (dot configuration data) 1 as shown in FIG.
4 is taken out from the storage section 8, sent to the printer 11, and printed out on paper 6. As shown in FIG.

Note that in order to speed up printing, image data development processing by the development processing section 7 and printing processing by the printer control section 13 are performed in parallel. In addition, in the case of color printing,
A storage section 8 is provided for each color (yellow, magenta, sheer black).

〔Effect of the invention〕

The present invention has the advantage that the capacity of the printing memo 11 can be reduced, making it easy to reduce the price of printers.
