Abstract

PURPOSE:To improve the availability of a memory area closing together the space parts, etc. produced in the latter half of a text line to hold continuously data by a buffer and showing the line divisions by the specific codes set between lines on the buffer or a means like a table showing the position of each line and the data length. CONSTITUTION:A processor 1 stores the print data covering the head of each line through the end of the valid data excluding the blanks, etc. of the rear part in a print buffer 10 with continuous lines in the print preprocessing of data on a page of a text. At the same time, the information of a prescribed style showing the divisions of each data between data of the buffer 10 is set to a division display means 11 in parallel with storage of the print data. Thus the processor 1 executes a line data output part 12 when the preprocessed text held by the buffer 10 is printed. The part 12 refers to the division informa tion of the means 11 to produce the print data out of the buffer 10 for each line and sends successively the print data to a printer 4 for printing.

Description

[Detailed Description of the Invention] [Overview] This is a processing method that reduces the buffer size when text is processed page by page and output to a printing device.

Fill in the blank space that occurs at the end of a line of text, hold the data continuously in the buffer, and use a specific code to separate the lines between the lines on the buffer, or specify the starting position and data length of each line. Indicate by means such as a table shown in the table. Please refer to this delimiter information.

Output row data sequentially from the file.

This method eliminates waste caused by two-dimensional buffers corresponding to pages of printed results.

[Industrial application field]

The present invention relates to a text print processing method for a system that processes text page by page and outputs it to a printing device.

When printing text, there are cases in which a processing device reads data for each page, performs processing such as arranging the layout within the page, and then outputs the data to a printing device.

[Conventional technology]

FIG. 4 is a block diagram showing an example of the configuration of a printing system.

By executing an appropriate program loaded into the main storage device 2, the processing device 1 reads the text to be printed, which has been separately created in advance and stored in the external storage device 3, for example, and executes the text required for printing. The data is pre-processed and output to the printing device 4 sequentially, for example, line by line.

The printing device 4 receives the sequentially sent data, holds the required number of lines of data in a buffer, and prints print characters, for example, one character at a time, while interpreting control symbols for the data on the buffer.

In a printing system with a relatively advanced print control function, processing such as so-called prohibition processing is performed, and page allocation is considered based on the result, and in order to move the heading so that it does not fall on the bottom line of the page, etc. In pre-printing processing, one page of data is expanded into the page buffer 5 of the main storage device 2 and processed.

FIG. 5 is a diagram showing an example in which one page of text data is arranged in the page buffer 5. As shown in FIG.

As conceptually shown in the figure, the page buffer 5 is configured as a so-called two-dimensional buffer area in which a fixed length area is allocated to each line in accordance with the line structure of the page to be actually printed. , text data is arranged as shown in the example in the figure.

[Problem that the invention seeks to solve]

Since the page buffer is taken as described above, as is clear from the example in the figure, in the spaces at the end of each line or completely blank lines that often occur in the text (indicated by = in the figure), There is a problem in that the storage area is used unnecessarily and the storage area is used inefficiently.

[Means for solving problems]

FIG. 1 is a block diagram showing the configuration of the present invention.

[For production]

In pre-processing for printing data for one page of text, the processing device 1 sequentially stores print data from the beginning of each line to the end of the print data, excluding trailing blanks, in the print buffer 10 for each line. .

In addition, in parallel with storing the print data, the delimiter display means II
In the print buffer 10, information in a predetermined format indicating the delimiter between each line of data is set.

In this way, when printing the preprocessed text held in the print buffer 10, the processing device 1 executes the line data output unit 12.

The data output unit I2 converts the print data line by line from the print buffer 10 by referring to the delimiter information of the delimiter display means 110, and sequentially outputs the mark and t11 data to the printing device 4 for printing.

With the above method, the recording tα area required to hold one page of print data is reduced.

C Embodiment) FIG. 2 is a diagram illustrating the configuration of the print buffer 1o and the delimiter display means 11 in one embodiment.

In FIG. 2, the same text data as in the example in FIG. 5 is arranged in the print buffer 2o, excluding the invalid portions in the latter half of each line and blank lines.

In the method of this embodiment, a specific delimiter code (shown particularly in the figure) is inserted at the end of each line of data to serve as a delimiter display means.

That is, the line data output unit 12 sequentially extracts character data from the beginning of the print buffer 20, checks whether it is a delimiter, and if not, outputs it to the printing device 4, and if the extracted character is written, Treated as the end of one line.

FIG. 3 is a diagram illustrating another embodiment, which includes a print buffer 21 and a management table 22.

In the print bar 21, data from the beginning of each line of text to the end of valid data is continuously stored as shown in the figure.

The management table 22 consists of entries corresponding to each line of the page to be printed, and each entry includes a start address field 23 that indicates the first character position of each line of data on the print buffer 21, and a length of the data for that line. It consists of a data length column 24.

In this case, the line data output unit 12 learns the position on the print buffer 21 of the line data to be output to the printing device 4 from the start address field 23 of the corresponding line in the management table 22, and from that position is specified in the data length field 24. The data for the number of characters is read from the print buffer 21 and output.

At this time, for example, it is checked whether the content of the data length column is 0, and if it is 0, the print buffer 21 is not read (and this line is treated as a completely blank line).

In the method shown in FIG. 2, a specific line cannot be accessed unless the print buffer 20 is read sequentially from the beginning, but in the method shown in FIG. This method has the advantage of directly accessing the required row data, but has the disadvantage of requiring additional storage space for the table in addition to the buffer.

Note that, if necessary, both methods may be used together.

With the method explained above, the amount of buffer required for preprocessing the print page is reduced by approximately 62% in the examples of Figures 5 and 2.
In general, it can be expected that the storage area usage efficiency will be improved.

〔Effect of the invention〕

As is clear from the above explanation, according to the great invention, there is no waste in the buffer that holds page data for printing 11 processing in the printing system, so it is a remarkable invention that the efficiency of storage area usage is improved. It has a positive effect.
