Abstract

PURPOSE:To uniformize the size of surface block by applying preferential order to the em character in a text when the max. number of characters is larger than the possible max. number of characters to convert the em character to a half em character and contracting rule data in matching relation of a compressed character row by a surface contraction means. CONSTITUTION:When the number of characters at every line of a document is inputted, one em character is set to 2 and one half em character and one rule character are set to 1 to calculate the number B of characters. The number of characters printable on one line of a printer is set to A to be compared with the number B of characters and, at a time of A>=B, it is judged that printing is possible to execute a surface contraction means. At a time of A<B, it is judged that characters protrude at a time of printing and, when there is the mark of em in an inputted document, the em is converted to a half em and the number of characters is again calculated at every line. At the time of A>=B, it is judged that printing is possible and surface contraction control is executed and, at the time of A>=B, the alphabet, numeral or katakana of the em in the inputted document is converted to a half em and the number of characters is again calculated. At the time of A>=B, it is judged that printing is possible and surface contraction control is executed and, at the time of A<B, a warning message is displayed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document printing apparatus for printing a document consisting of a text character string on a printer, and more particularly to a character compression printing apparatus suitable for compressing and printing a table including ruled lines.

[0002]

2. Description of the Related Art In a conventional word processor or table creation program, when a text character string is written in a rectangular area (hereinafter referred to as a block) surrounded by a ruled line, the number of characters is different from the size of the block. In many cases, as a display method, the block is expanded by enlarging the table in the horizontal direction or the vertical direction, and the text character string is arranged and printed in the block.

As a reference for this type of technique, there is JP-A-63-75964.

[0004]

The above-mentioned conventional technique is
There is a problem that the table becomes large by widening the blocks, which may cause a line span or a page span of the table during printing.

When a person writes a character on a table block by handwriting, if the number of characters to be written in this table block is large with respect to the table block, the character is written small or the character interval is narrowed to make the table block. It is common to write to enter.

An object of the present invention is to focus on the above empirical facts, reduce a text character string to fit a table block,
An object of the present invention is to provide a character compression printing device that performs processing of printing by reducing the table itself according to this text character string and printing.

[0007]

SUMMARY OF THE INVENTION The above object is to calculate the number of characters in each line of a text character string in a document printing apparatus for printing a document consisting of a text character string and a table containing the ruled line data on a printer. Character count calculation means,
The maximum character number calculation means for calculating the maximum value of the number of characters for each line calculated by the character number calculation means, and the maximum printable character number of one line and the maximum character number calculated by the maximum character number calculation means are compared, and the maximum character number is When the maximum number of printable characters is exceeded, full-width characters existing in the document are converted into half-width characters according to a predetermined priority and a new document is generated, and a character compressed by the character conversion means. This is achieved by providing a table reducing unit that reduces the line data according to the columns and a unit that prints the newly generated document on the printer.

[0008]

According to the above, the character number calculating means calculates the maximum value of the number of characters calculated for each line of the input text, and when the character converting means determines that the maximum number of characters is larger than the maximum printable character number. Double-byte characters in the text are given priority and converted to half-width characters, the table reduction means reduces the line data according to the compressed character string, and the printing means prints the character string including the table. By doing so, the document is compressed and printed.

Therefore, even when the document is tabular data including a ruled line, the table can be reduced in size in accordance with the compression of characters and the size of the table block can be made uniform.

2, a symbol / character conversion step 403 for converting full-width symbol characters to half-width characters, and an alphanumeric kana character conversion step 4 for converting full-width alphabets, numbers, and kana characters to half-width characters
06, a protrusion control step 409 that performs a warning process and the like when a character is compressed, but a table reduction control step 410 that reduces the table according to the degree of reduction of the character, and the compression processing ends. And a print control step 411 for printing the document.

Next, the operation of the character compression printing control of this embodiment having the above-mentioned configuration will be described. In the character number calculation unit 302, the keyboard 109, the external storage device 111,
The number of characters per line of the document input from 112 is input (step 401). One line from the beginning of the document or the character following the line feed code (0DH, 0AH) to the next line feed code. When calculating the number of characters, one full-width character is two, one half-width character is one and one line is one.
Calculate as The number of characters that can be printed on one line of the printer is determined by the printer. Therefore, since this number of characters does not change, either enter from the keyboard 109 or
Or is it input from the external storage device 111, 112?
Alternatively, the fixed value may be held in advance by the character compression printing control unit. Here, this value is A. Let B be the maximum value of the characters calculated for each line calculated in the line character number calculation step 401. Then, by comparing A and B, it is determined that printing is possible when A ≧ B (step 402), and the table reduction control (step 410) is executed. When A <B, it is determined that the character is projected during printing, and if there is a full-width symbol in the input document, it is converted into a half-width (step 40).
3).

Here, the full-width symbol characters are (Kanji space) ,! , ", #, $,%, &, ', (,), *,
+ ,,,-,. , /,:,;, <, =,> ,? ，
@, [, \,], ^, _ ,,, {, |,},
￣. , ",", And.

Next, the number of characters is calculated again for each line in the document after the full-width symbol characters are converted into half-width characters. Step 405 is the same process as step 402. Then, A is compared with B, it is determined that printing is possible when A ≧ B (step 405), and the table reduction control (step 410) is executed. When A <B, it is determined that printing will be overhanging, and if there are full-width alphabets, numbers, and katakana in the input document, they are converted to half-widths (step 406).

Here, the full-width alphabet is A,
B, C, D, E, F, G, H, I, J, K, L, M,
N, O, P, Q, R, S, T, U, V, W, X, Y,
Z, a, b, c, d, e, f, g, h, i, j, k,
l, m, n, o, p, q, r, s, t, u, v, w,
x, y, z, full-width numbers are 0, 1, 2, 3, 4,
5, 6, 7, 8, 9 and full-width katakana are
U, d, o, mosquito, ki, ku, ke, ko, sa, shi, su, se,
So, Ta, Chi, Tsu, Te, To, Na, Ni, Nu, Ne, No, Ha,
Hi, fu, he, ho, ma, mi, mu, me, mo, ya, yu, yo,
La, Li, Le, Le, Ro, Wa, N, Wo, A, I, U, E,
Let's say that In addition to this, full-width katakana includes dakuon characters and semi-dakuon characters. However, since the half-width characters corresponding to these are represented by the two characters of the syllabary character and the dakuten, or the syllabary character and the half-dakuten, one half-width character cannot be represented. Therefore, the double-byte kanji voiced characters and semi-voiced characters are not converted.

Next, the number of characters is calculated for each line again for the document after the full-width alphabets, numbers and katakana have been converted into half-width characters. Step 408, step 402
Is the same process as. A is compared with B, and when A ≧ B, it is determined that printing is possible (step 408), and table reduction control (step 410) is executed.

When A <B, it is determined that the toner will protrude during printing, and the protrusion control step 409 is executed. In step 409, even if the document is compressed by the conversion, a warning message is displayed to inform that the document will be protruded at the time of printing, and the printing is executed for the user who requests the printing. This process ends for users who do not request printing.

Details of the table reduction control step 410 are shown in FIG. First, a row pointer indicating the number of rows currently being processed is initialized (step 501). Next, it is searched whether or not the processing line has a vertical stroke (step 502). If there is no vertical bar, the row pointer is updated by incrementing the row pointer by 1 (step 506). When the vertical ruled line is found, the number of columns having the vertical ruled line is held for each row (step 503). If there are space characters immediately before the vertical stroke, all of them are deleted, and the number of deleted space characters is subtracted from the number of columns with vertical stroke held in step 503 to update the vertical stroke position (step 5).
04). If the next line still exists (step 50
5) The row pointer is updated by incrementing the row pointer by 1 (step 506) and the procedure returns to step 502. If the next line does not exist, the line pointer is initialized (step 507). The maximum number of columns of vertical grid lines held in step 503 is acquired (step 50).
8). Let it be M. Insert a space just before the vertical ruler until the vertical ruler position is this M (step 5).
09). If the next line still exists (step 51
0), the row pointer is updated by incrementing the row pointer by 1 (step 511), and the process returns to step 509. If the next line does not exist, the horizontal stroke lines of all the lines including the horizontal stroke line are deleted until the number of line characters reaches M (step 512). As described above, the table reduction control is completed, and then the print control step 411 is executed.

In step 411, printing is executed using the BIOS, which is an I / O control program prepared on the computer side. It can also be realized by directly outputting a document which is print data to a printer output port.

According to the above-mentioned embodiment, the character compression printing is performed as follows. FIG. 6 shows an example of the printing. 7 (a), (b), and (c) are diagrams showing how the characters in the table of FIG. 6 are converted, and the characters are moved as they move to (a), (b), and (c). Are successively reduced.

First, assume that a table as shown in FIG. 6 is input. Since 13 double-byte characters have been entered, the number of characters is (number of double-byte characters) * 2 + (number of vertical strokes) = 13 * 2 + 2 =
28 (step 401). If the printer can print 28 or more characters per line (step 402), the table reduction control (step 410) is executed. If it is less than 28, full-width symbol characters are converted to half-width characters (step 403). Among the characters that have been input, the full-width symbol characters are ",,,? Since they are converted to half-width characters. Focusing on the characters, they are converted as shown in Fig. 7 (a). The characters are 9 double-byte characters,
Converted to 4 single-byte characters, the number of characters is (number of double-byte characters) * 2 + (number of single-byte characters) + (number of vertical strokes)
= 9 * 2 + 4 + 2 = 24 (step 404). If the number of characters that the printer can print in one line is 24 or less (step 405), the table reduction control (step 410).
To execute. If it is less than 24 characters, full-width alphabets, mathematics, and katakana are converted into half-width characters among the full-width characters of the input character (step 406). That is, full-width M, O, J, I, 4, K, and N in the input characters are converted into half-width M, O, J, I, 4, K, and N, respectively (Fig. 7 (c)). The entered characters are converted into 2 full-width characters and 11 half-width characters, and the number of characters is (number of full-width characters) * 2 + (number of half-width characters) + (number of vertical strokes)
= 2 * 2 + 11 + 2 = 17 (step 407). If the printer can print 17 or more characters per line (step 40)
8) The table reduction control (step 410) is executed. 17
If it is less than the character, the protrusion control (step 409) is executed. In step 409, even if the document is compressed by the conversion, a warning message is displayed to inform that the document will be protruded at the time of printing, and the printing is executed for the user who requests the printing. Also, (the number of characters after conversion) -M is calculated, and the number of characters protruding is displayed. It becomes easy for the user to refer to the number of characters protruding and make a decision that the paper size larger than that currently set in the printer should be used. This process ends for users who do not request printing.

In the table reduction control (step 410), first, the row pointer is set to 1 (step 501). Since the first line in FIG. 6 has no vertical ruled line (step 502),
The row pointer is incremented by 1 (step 502). Second
The vertical stroke except the beginning of the line is in the 18th column (step 503). There is one single-byte space immediately before the vertical bar in the 18th column, and this is deleted (step 5
04). As a result, the number of characters in this line is (the number of converted characters) + (the number of vertical strokes) − (the number of deleted space characters) = 16 + 2-1 = 17 characters. This is stored for each row. This is repeated until there is no next row (step 505). Next, the row pointer is set to 1 (step 507). The maximum value of the number of characters in the previously stored line (position of vertical stroke line column) is calculated (step 508). This maximum value is 20. Next, the vertical stroke position is 20 for the line with characters.
A space character is inserted immediately before the vertical stroke so that it becomes the column eye (step 509). This is repeated until there is no next row (step 510). The horizontal stripes are deleted until the number of characters in the row having the horizontal stripes becomes 20 (step 512). Then, the process returns to the character compression printing control, the printing control (step 411) is executed, and the printing is output to the printer.

In this way, in the process of converting full-width characters, the conversion priority is set according to the type of full-width characters,
Character compression printing can be easily performed by reducing the scale line according to the length of the converted character string.

The size of paper determines the number of characters that can be printed in one line. By holding the number of characters for each size of this paper in advance, these values and the number of characters after conversion are sequentially compared, and (the number of printable characters of the paper size)> (the number of characters after conversion) is obtained. Determine the paper size. By displaying this paper size, the user can easily determine which size of paper should be used to print without overflowing.

The above-described embodiment is a process for one block (portion surrounded by a dashed line) vertically arranged in one line. Next, an example of a plurality of blocks will be described.

FIG. 8 is a diagram showing a table of plural column blocks. A (i, j) (1 ≦ i ≦ m, 1 ≦ j ≦ n,
i, j, m, and n are positive integers) are character strings including full-width characters and half-width characters. In the case of such a table, the first column is first compressed and then the second column using the process described in the previous embodiment.
This can be realized by compressing columns and sequentially compressing up to the nth column.

In the above-mentioned embodiment, the compression processing is realized by paying attention to the number of characters. The length of one line can be further compressed by focusing on the number of dots.

FIG. 9 is a flowchart focusing on the number of dots in one line. The number of dots in one half-width character is d1, and the number of dots between characters is d2. The number of dots D1 in a line is D1 = (character length) * d1. Here, the character length is the number of dots of only characters excluding the number of dots between characters. Therefore, (character length) = (number of half-width characters + number of full-width characters * 2) * d1. Further, the inter-character dot number D is D = (character number−2) * d2. The total number of dots in the row is D + D1 (step 901). Assuming that the maximum number of dots that can be printed in one line is M, if M ≧ D + D1, then it is determined that printing does not occur (step 90).
2) The table reduction control (step 913) is executed. If M <D + D1, it is determined that the protrusion occurs during printing, and the full-width symbol is changed to a half-width character (step 903). Step 903 is Step 4
The same process as 03 is performed. The number of dots D + D1 in the row is calculated again (step 904). If M ≧ D + D1, it is determined that no protrusion occurs during printing (step 90).
5) The table reduction control (step 913) is executed. In the case of M <D + D1, it is determined that the protrusion occurs during printing, and full-width alphabets, numbers, and kana are changed to half-width (step 906). Step 906 performs the same process as step 406. The number of dots D + D1 in the row is calculated again (step 907). If M ≧ D + D1, it is determined that no protrusion occurs during printing (step 90).
8) The table reduction control (step 913) is executed. In the case of M <D + D1, it is determined that the toner will protrude during printing, and the inter-character compression control is executed (step 909). In step 909, the number of dots D1 excluding the spaces between the characters is obtained and the number of dots between the characters is calculated. That is, the inter-character dot number d2 = (M−D1) / (number of characters) is calculated. The integer part of d2 is the number of inter-character dots to be obtained.

Next, when d2 <0, it is set as d2 = 0 though it is projected at the time of printing even if the character space is compressed. Number of dots between characters d
Since 2 is determined, the total number of dots in one row, D + D1, is determined.

If M ≧ D + D1, it is determined that no protrusion occurs during printing (step 91).
1) The table reduction control (step 913) is executed.

If M <D + D1, it is determined that the toner will protrude during printing, and the protrusion control (step 912) is executed. Step 913 is the same process as step 409. Further, step 913 is the same process as step 410. In print control, the number of inter-character dots is set to the value of d2 obtained in step 909 and output to the printer.

[0034]

As is apparent from the above description, according to the present invention, in the process of converting a full-width character into a half-width character, the full-width symbol character is converted into a character when converting first. By prioritizing priorities, it is possible to compress the document while balancing the character sizes.

Further, even when the document is tabular data including a ruled line, there is an effect that the table can be reduced and the size of the table block can be made uniform in accordance with the compression of characters.
