Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to a document creating apparatus having a variable function of a print character size and a character spacing.

[Technical Background of the Invention and Problems] In recent document creation devices such as Japanese word processors,
In many cases, the print character size and the character spacing can be changed.

In this type of document creation device, generally, even if an enlarged character is specified for a character on the display screen, or if an interval between characters is specified, the document on the display screen is displayed in full-width characters. Therefore, the printed image cannot be confirmed without reflecting the actual size and position of characters.

Therefore, in the conventional document creation device, when a document in which the character size or the inter-character spacing is specified is printed, there is a problem that the print character is cut off in the middle or exceeds the specified horizontal print range. .

[Object of the Invention] The present invention has been made in view of the above circumstances, and its object is to solve the problem that when a character which does not fall within the print boundary or the specified print range occurs due to the designation of enlargement of the character size or the character spacing. Another object of the present invention is to provide a document creation device that can selectively prohibit printing of the corresponding character.

[Summary of the Invention] In the present invention, a first designating means for selectively designating one of a plurality of first inter-character space values in units of lines of document information to be output, and a plurality of units of document information in units of lines. Two designating means are provided, which is a second designating means for selectively designating one of the character magnifications. The first inter-character space value designated by the first designating means is the second
The conversion unit converts the second inter-character spacing value proportional to the designated magnification of the designation unit.

Further, according to the present invention, a print image storage means having a print image capacity for printing one line of full-width characters is provided. The writing start position of the character pattern for one print in the print image storage means is indicated by the first pointer, and the writing end position of the same pattern is indicated by the second pointer. The second pointer is set by the setting means based on the write start position indicated by the first pointer and the designated magnification of the second designating means. The writing end position indicated by the second pointer is compared with the final writing position of the print image storage means by the determination means to determine whether or not the character pattern can be written in the print image storage means. When the determination means determines that writing is possible and there is a next writing character pattern, the corresponding one printing character pattern is the second character pattern.
The pattern is expanded by the pattern expanding means at the specified magnification of the specifying means. The developed character pattern is written by the writing means in the area of the print image storage means starting from the position indicated by the first pointer. The first pointer is updated by the updating means based on the second pointer and the second inter-character space value in accordance with the writing operation of the writing means. On the other hand, the content of the print image storage means is printed when the determination means determines that writing is not possible, or when writing is possible but there is no next writing character pattern.

It has an area of ~ 63.

Referring again to FIG. 1, 31 is a keyboard interface (KB-IF) and 33 is a keyboard (KB). 35
Is a display controller (display CNT), and 37 is a display. The display device 37 is, for example, a liquid crystal display device of 1 row × 10 characters. The display pattern displayed on the display 37 is stored in the display dot memory 39.

41 is a printer interface (PRT-IF), 43 is C
A printer (PRT) that prints Chinese characters under the control of PU10. The printer 43 is, for example, a thermal transfer printer having a print head of 24 dots. Reference numeral 45 is a set interface (CMT-IF), and 47 is a cassette magnetic tape unit (CMT) used as a data recorder for storing documents and the like.

FIG. 3 is a diagram for explaining the structures of the document area 21 and the line modification area 22 provided in the RAM 20, and the document information (character code string) and the line modification information are stored in a state where they are associated with each other on a line-by-line basis. To be done. The line decoration information is a white flag that specifies the outline (and shadow) of the character, 3-bit rotation / italic information that specifies the form (rotation, italic) of the character, and 4-bit character size that specifies the character size. Information, a print stop flag that specifies a print stop during printing, 2-bit inter-character space information that specifies a character space, and 4-bit line pitch information that specifies a line pitch (line feed pitch).

The above-mentioned line modification information can be set interactively in units of lines by the operator operating the keyboard 33 while looking at the display screen of the display 37. For example, for setting character size information, a character size screen is displayed by key operation, and numbers 1 to 9 (actually 1 to 5 and 6 to
This can be done by specifying one of the two screens (9). The character-to-character interval information is set by displaying the character-to-character interval screen by key operation and designating one of the numbers 0 to 3 on this screen by the key. Similarly, to set the line pitch information, a line pitch screen is displayed by key operation, and one of the characters B, O, H, K, E, 1 to 3 (actually B, O, H It is carried out by designating keys (K, E, 1 to 3 screens).

When the above key designation is not made (information), a preset standard set value is applied. This standard setting value is 24 (vertical) x 24 for character size.
(Horizontal) is 1 indicating a dot, and is 1 indicating 3 dots in the case of character spacing (character spacing based on the standard character size, that is, full-width character size in this example), and line pitch (in this example If the line pitch is based on full-width character size, then 30/120 inch (3 dots is 2/1
In this example, which is 20 inches, 45 dots)
(This value is a display character on the screen and is actually "010
0 ").

Next, the operation of the embodiment of the present invention will be described.

In this embodiment, the print control by the CPU 10 is performed according to the flowchart of FIG.

When the operator wants to print the input document (or the edited document), he operates the [Print] key (actually, [Function] key and [\] key) of the keyboard 33. If there is a key input, the CPU 10 checks whether or not a [print] key input has been performed (step S1), if NO, performs other key input processing (step S2), and if YES, executes step S3. To do. In step S3, the print line pointer K indicating the document line to be printed and the next print start line N indicating the first line of the document lines to be printed in the next print cycle are initialized to 1 respectively. It The next print start row N and print row pointer K are RAM
It is set in registers 51 and 52 secured in 20.

CPU10 will display a print menu, if step S3 is performed (step S4). In this state, the operator can specify left margin and vertical / horizontal printing. After this, select
When the key is operated by the key and the CPU 10 judges to that effect (step S5), the CPU 10 refers to the line modification information of the Nth line of the line modification area 22 secured in the RAM 20, and checks the print stop flag ( Step S6). And C
The PU 10 determines whether or not the print stop is designated by the print stop flag (step S7), and if NO, checks the document line in the document area 21 corresponding to the Nth line (step S8). Then, the CPU 10 determines whether or not there is no character code in the relevant document line, that is, whether or not it is the document END (step S9). If it is not the document END, the Nth line set as the next print start line is one of the document lines to be printed from now on, and is not (the first line of) the document line to be printed in the next print cycle. Therefore, the CPU 10 increments N by 1 to set a new next print start row N (step S10). When step S10 is executed, the process returns to step S6, and the above-described processing (determination of presence or absence of print stop designation, determination of document END) is performed for the newly set Nth line.

When the CPU 10 determines in step S7 that the Nth line printing stop is designated, or when the document END is determined in step S9, the CPU 10 calculates N-1 and prints in the current print cycle. The number of print lines M indicating the number of document lines (not the number of lines as a print result) is obtained (step S11). The number of print lines M is set in the register 53 secured in the RAM 20. Next, the CPU 10 determines whether M is 0 (step S12). If M = 0, the CPU 10 ends the print control (because there is no print line). On the other hand, if M = 0 is not satisfied, the CPU 10 first fetches the line modification information of the Kth line indicated by the print line pointer K from the line modification area 22 in preparation for printing (step S1).
3). Next, the CPU 10 executes step S14 to obtain the actual line feed amount T.

In step S14, first, based on the character size information in the line decoration information, the vertical dot number m and the horizontal dot number m'of the character of the size designated by the information are prepared in, for example, the ROM 12 in the character size table (Fig. 24 × 2 calculated from (not shown)
Magnification based on 4-dot double-byte characters (vertical magnification m / 2
4, lateral magnification m '/ 24) is obtained. Similarly, based on the line pitch information in the line modification information, the line feed amount (n / 120, unit: inch) based on the double-byte character specified by the information is provided in, for example, the ROM 12 line feed amount table (Fig. (Not shown). Then, by multiplying the line feed amount n / 120 by the vertical scale factor m / 24, the actual line feed amount T for the character string of the character of the designated character size (character scale factor) is obtained, and is stored in the register 54 secured in the RAM 20. Is set. At this time, the line feed amount T may be obtained by further multiplying by a certain proportional constant k.

The line feed amount indicated by the line pitch information is expressed in the format of n / 120 because the paper feeding unit of the printer 43 in this embodiment is 1/120 (inch). Therefore, n / 120 indicates paper feeding for n units. Similarly,
The line feed amount T (m · n / 24) / 120 indicates a line feed paper feed of (m · n / 24) unit in proportion to the designated magnification. However, since n / 120 and (m · n / 24) / 120 are not integers, the n part of n / 120 is actually
Only the portion (m · n / 24) of (m · n / 24) / 120 is the table in the ROM 12 and the register 54 in the RAM 20.
It will be remembered in. In this example,
n is a positive / negative indicating the line feed direction as is clear from FIG.
It has a minus sign. It should be noted that the above m, m ', n can be set in advance in the print control program instead of the table.

Now, the number of dots of the print head of the printer 43 is 24, which corresponds to the number of vertical dots of the double-byte character. For this reason, a character string of a character having a vertical dot number of more than 24 dots, such as an enlarged character, cannot be printed by operating the print head for one line, and needs to be printed several times. Therefore, in this embodiment, the number of slices S of (the character pattern of) the print target character is calculated when the vertical 24 dots are one slice (step S15). This slice number S
Is calculated based on the specified character magnification and the character form. Here, for simplicity, the magnification is m / 2.
4 is required. However, when m / 24 is not an integer, an integer larger than that value and closest to the value is adopted. For example, if m = 32 (size 2 is designated), S = 2 is adopted. Step S
The number of slices S obtained in 15 is set in the register 55 secured in the RAM 20. When the step S15 is completed, the CPU 10 initializes the slice number pointer L indicating the slice to be printed in the print head driving operation for one line to 0. L = 0 indicates the first slice.

Next, the CPU 10 determines, based on the inter-character spacing information in the line modification information of the k-th line, the inter-character spacing (n 'dot) based on the double-byte character designated by the information, for example, the character prepared in the ROM 12. An actual inter-character spacing U (unit: dot) proportional to the magnification is obtained by multiplying n'by a lateral magnification m '/ 24 from a distance table (not shown) (step S1).
7). The inter-character space U is set in the register 61 secured in the RAM 20.

After executing step S17, the CPU 10 sets the number of characters of the character string of the Kth line (in the document area 21) indicated by the print line pointer K as the number of print characters of the Kth line V, and the register 57 in the RAM 20.
(Step S18). And the CPU 10 is the Kth
The Kth in-line character pointer P designating the character position (character digit) of the character to be taken out next from the character string of the line is initialized to 1 (first character digit) (step S19). The character pointer P is set in the register 58 in the RAM 20.

Next, the CPU 10 sets the character pattern of the slice L (L = 0) of the character (kth row, Pth column) designated by the print row pointer K and the character pointer P (P = 1) in the print image area 26 in the RAM 20. In order to write, the write start address Q in the print image area 26 is obtained in consideration of the left margin (step S20). This write start address Q (print image area
If the left margin corresponding to d dots is required, the relative address within 26 will be 3d, as will be understood from the configuration of the print image area 26 described below. The write start address Q is set in the register 59 in the RAM 20.

FIG. 5 schematically shows the structure of the print image area 26 corresponding to the print area (1 slice print area) in the print head driving operation for one line. As is clear from the figure, at addresses 0 to 3 of the print image area 26 (relative addresses in the print image area 26), 8 dots (1 byte) of the 0th dot row (24 dots) of the print area for one slice are used. ) Corresponds to each area divided into three. Generally, the print image area
26 3n, 3n + 1, 3n + 2 addresses (print image area
26 relative address) corresponds to each area obtained by dividing the n-th dot row (24 dots) of the printing area for one slice into three by 8 dot (1 byte) units. Therefore, if the left margin for d dots is required, the write start address Q is 3d as described above.

After executing step S20, the CPU 10 obtains the write end address R in the print image area 26 of the character pattern of the slice L of the character on the Kth row and the Pth column (step S21). The write end address R corresponds to the first 8 bits of the last dot row of the character pattern of the slice L. In this example in which the horizontal dot number is m ', the write start address Q is 3
It is obtained by adding (m'-1). The write end address R is set in the register 60 in the RAM 20.

When the CPU 10 obtains the write end address R, it compares the same address R with the last write address LE, and R is L.
It is determined whether it is larger than E (step S22). This write final address LE indicates the first 8 dots of the final dot row (that is, the print boundary) of the 1-slice print area, as shown in FIG. 5, for example. Therefore, from step S22, it can be determined in advance whether or not a part of the character pattern of the slice L of the character on the Kth row and the Pth column exceeds the printing boundary.

Regarding the significance of the above step S22, FIG. 6 and FIG.
A specific description will be given with reference to FIGS. Now, the character pattern of the character on the Kth row and the Pth column is an enlarged character pattern of a 48 × 48 dot configuration as shown in FIG. 6 by designating the row pitch information (size 5) in the relevant row decoration information. There is. Here, for example, the character pattern of slice 0 of the enlarged character pattern of FIG.
Consider the case of writing to. If the write end address R for the character pattern of slice 0 (same for the character pattern of slice 1) is not larger than the write end address LE, the storage state in the print image area 26 of the pattern is as shown in FIG. 7 (a). Next to the print image area 26
When the content of is printed, the above pattern does not cross the print boundary. On the other hand, if the write end address R for the character pattern of slice 0 (the same applies to the character pattern of slice 1) is larger than the write end address LE, the storage state in the print image area 26 of the pattern is as shown in FIG. 7 (b). As shown, when the contents of the print image area 26 are printed, a part of the above pattern crosses the print boundary, and thus a part of the character pattern is missing.
That is, in step S22, when the enlarged character pattern is unconditionally written in the print image area 26, it is determined in advance whether the pattern will be printed without missing. The final write address LE is not limited to the print boundary fixed to the apparatus as described above, but may be a print range specified by the operator such as the right margin. In this case, in step S22, when the enlarged character pattern is unconditionally written in the print image area 26, it is determined in advance whether or not the pattern is printed without exceeding the print range.

If the determination in step S22 is NO, the CPU 10 specifies the Kth row Pth designated by the print row pointer K and the character pointer P.
The character (character code) in the row is taken out from the document area 21 (step S23), and it is determined whether or not the character code is a line feed code (no pattern writing is required) (step S2).
Four). If it is not the line feed code, it is necessary to write the pattern. Therefore, after the character pointer P is incremented by 1 to advance to the next character position (step S25), the character pattern corresponding to the character code extracted in step S23 is stored in the ROM 12 It is taken out from the character pattern area 16 (step S26). The character pattern stored in the character pattern area 16 is
This is a full-width character pattern composed of 24 × 24 dots (72 bytes). The character pattern extracted from the character pattern area 16 is temporarily stored in a predetermined one-character storage area (not shown) in the RAM 20.

After executing step S26, the CPU 10 determines whether or not the change of the character size or the character form is requested by the line modification information of the Kth line, that is, whether the conversion of the character pattern is necessary (step S27). . If the pattern conversion is necessary, the CPU 10 sequentially converts the character pattern (that is, the original character pattern) in the one-character storage area into a character pattern of a specified size or form (step S28), and the pattern conversion is necessary. If not, the step S28 is skipped, and thereafter, the character pattern of the slice number (that is, the slice L) indicated by the slice number pointer L (if step S28 is skipped, it is a full-width character, so the character in the one-character storage area is Pattern) is written in the area starting from the relative address in the print image area 26 indicated by the write start address Q (step S29).

When the CPU 10 executes step S29, the write start address Q indicates the write start address of the next one character (one slice thereof) by adding the triple value of the intercharacter space U (dot) to the write end address R. Thus, the same address Q is updated (step S30). This realizes a U-dot spacing between characters. The inter-character spacing U is obtained in step S17 as described above, and is not the inter-character spacing based on double-byte characters specified by the character size information, but the specified inter-character spacing (specified by the character size information. It is obtained by multiplying by a magnification (horizontal magnification), that is, an actual intercharacter space proportional to the magnification. Therefore, in this embodiment, while the character spacing is specified by the image of full-width characters, the character spacing suitable for the actual character size is automatically realized.

After executing step S30, the CPU 10 decrements the number of print characters V by -1 (step S31), and determines whether V becomes 0 (step S32). If V is not 0, C
The PU 10 returns to step S21 on the assumption that an unprocessed character remains in the Kth line. On the other hand, if V = 0, then C
In PU10, all the characters in the Kth line are extracted and the corresponding character pattern (character pattern of slice L) is in the print image area.
Assuming that the data has been written in 26, the process proceeds to a process centered on the control of the printer 43 for printing the Kth line starting from step S33. Even if the process starting from step S33 is V =
Even if it is not 0, if the determination in step S22 is YES (that is, the write end address R is greater than the write end address LE), or if the determination in step S24 is YES (that is, the character code extracted from the document area 21 is In the case of a line feed code), that is, when the printing of the corresponding character in the Kth row and the Pth column is prohibited or unnecessary, it is executed.

The CPU 10 first determines whether or not the character pointer P indicates 1, that is, whether or not the step S25 for incrementing P by 1 has not been executed at all (step S33). If P
If = 1 is not satisfied, the CPU 10 determines that the first character of the Kth line is not a line feed code (that is, not a complete line feed),
That is, it is determined that the character pattern to be printed is written in the print image area 26, and the printer 43 is controlled to print the content of the print image area 26 (step S34).
Next, the CPU 10 clears the print image area 26 (step S35), and then subtracts the slice number S by -1 (step S36). Then, the CPU 10 determines whether or not the slice number S is 0, that is, whether or not the printing of the character string in the Kth row is completed (step S37).

When the determination in step S37 is NO, the CPU 10 determines that the printing of the Kth row is not completed, first increments the slice number pointer L by 1, and specifies the slice number of the slice to be printed next ( Step S38). And CP
The U10 controls the printer 43 so that the next slice is connected to the slice printed in step S34 (that is, the interval between slices becomes 0), and the print paper is divided into print head portions (vertical dot portions of full-width characters). ) Is fed in the forward direction (step S39). As described above, the paper feeding unit of the printer 43 is 1/120 (inch), the dot composition of the print head is 24 dots, and the three dots are 2/120 inches. Therefore, the CPU 10 causes the printer 43 to perform forward paper feed of 16/120 (inch) in step S39. After executing step S39, the CPU 10 returns to step S18 and performs the process for printing the next slice for the same character string in the Kth row as the previous time.

On the other hand, if the determination in step S37 is YES, that is, if the printing of the character string in the Kth row is completed and the slice number S becomes 0, the CPU 10 realizes the line feed indicated by the line feed amount T.
The value obtained by multiplying L by 16/120 (that is, the paper feed amount required for printing the character string in the Kth row) is T, that is, (m · n / 24) / 12.
It is subtracted from 0, and the result is again set as the line feed amount T (step S40). The absolute value of the newly calculated line feed amount T is
The paper feed amount (inch) for the line feed paper feed to be performed after the printing of the Kth line is shown, and the same sign (plus / minus sign) shows the paper feed direction. As is apparent, when the K-th line is full-width character designation (size 1), L remains 0 (that is, the printing paper feed of step S39 is not executed), so the newly obtained T is It matches the T found in S14.

When the CPU 10 executes step S40, or step S40
When YES (P = 1) is determined in 33, it is determined whether or not the line feed amount T is 0 or more (that is, whether or not the paper is fed in the forward direction) in order to determine the paper feeding direction (step). S4
1). When the determination in step S33 is YES, the execution of printing in step S34 is skipped because the first character of the Kth line is a line feed code, which is a complete line feed. If T ≧ 0, the CPU 10 causes the printer 43 to perform T-inch forward paper feeding (step S42), and
If <0, the printer 43 performs reverse paper feed for the absolute value of T.
(Step S43). As a result, the actual line feed pitch is the line pitch (line feed pitch) based on the ratio between the line feed pitch and the character size (the number of vertical dots) of the print character on the Kth line based on the double-byte character specified by the line pitch information. Is expressed so as to match the ratio of the vertical dot number of the full-width character. That is, in this embodiment, it is possible to realize a line pitch proportional to a character of a size designated by the character size information while designating a line pitch (line feed pitch) with respect to a double-byte character. If the determination in step S33 is YES (that is, in the case of complete line feed), printing is not executed, so T obtained in step S14 is used as it is.

Now, in this embodiment, as the row pitch information, B, O,
Nine kinds of H, K, E and 1 to 4 are prepared (see FIG. 3).

The line feed B (reverse line feed, back line feed) specifies that a line feed is made in the reverse direction by 8/120 (inch) based on the double-byte character. In this case, the paper feed amount after printing the character string of the Kth row is the line pitch (minus value) for the character string of the specified character size obtained by multiplying -8/120 (inch) by the vertical magnification, and the same character string is obtained. Is the absolute value of the value obtained by subtracting the paper feed amount required to print (the total paper feed amount of the paper feed performed for printing the same character string), and the subtraction result is negative for that paper feed direction. Therefore, it is the opposite direction. Therefore, when the line feed B is designated, a backward line feed of 1/2 character of the character size designated by the character size information is realized.

Line feed O (line pitch 0) specifies a line feed amount of 0. In this case, the paper feed amount after printing the character string in the Kth row is equal to the paper feed amount required to print the same character string (total paper feed amount of paper feed performed for printing the same character string). It matches the absolute value and the paper feed direction is opposite. Therefore, when the line feed O is designated, the line pitch 0 (0 line feed) is realized regardless of the character size designated by the character size information. When the number of vertical dots is 24, the total paper feed amount during printing is 0, so the paper feed amount after printing is also 0.

Line feed H (half line feed, half line feed) specifies that a line feed is made in the forward direction by 8/120 (inch) based on the double-byte character. In this case, the paper feed amount after printing the character string in the Kth row is +8/120 (inch) multiplied by the vertical magnification, and the same character string is printed from the line pitch for the character string of the specified character size. It is the absolute value of the value obtained by subtracting the required paper feed amount (total paper feed amount of paper feed performed for printing the same character string), and the paper feed direction is the sign of the subtraction result (normal /
Negative) is the direction indicated. Therefore, when the line feed H is specified, 1 of the character size specified by the character size information
A forward line feed (half line feed) of only two characters is realized.

The line feed K (line feed for a ruled line, line feed for one character) specifies that a line feed is made in the forward direction by 16/120 (inch) based on a double-byte character. In this case, the paper feed amount after printing the character string of the Kth row is the same as that for printing the character string from the line pitch for the character string of the specified character size obtained by multiplying +16/120 (inch) by the vertical magnification. A value obtained by subtracting the required paper feed amount (total paper feed amount of paper feed performed for printing the same character string), that is, 16/120 (inch), and the subtraction result is positive for the paper feed direction. It will be the forward direction. When the vertical magnification is an integer, the specific paper feed amount at this time is a character size with a magnification of 1, that is, 16/120 (inch), which is a fixed amount. On the other hand, when the vertical magnification is not an integer, the forward paper feed amount is the character size of the magnification indicated by the fractional part of the vertical magnification. Therefore, when the line feed K is designated, a line feed of only the characters of the character size designated by the character size information, that is, a line feed with a line spacing of 0 is realized.
Since this line feed K can set the line spacing to 0 as described above, that is, the first character string of the first character size and the second character string of the second character size following the same character string. Since they can be connected without any gaps, it is suitable when, for example, an enlarged ruled line (especially a vertical ruled line) is created. In addition,
When a horizontal ruled line is created, the character spacing may be set to zero.

In addition, line feed E (English line feed) specifies that the line feed is 20/120 (inch) in the forward direction based on full-width characters, and line feeds 1, 2, 3, 4 are based on full-width characters. 30/120, 40/120, 45/120, 60
Specifies forward paper feed of / 120 (inch).

FIGS. 8 to 10 show the above specific examples.

FIG. 8 shows a document printing example in which the same value is specified for the character spacing and the line pitch (line feed amount) and different values are specified for the character size for each document character string. This is shown corresponding to the contents (a part) of the line modification area 22. In FIG. 8, character size 1,
The line feed pitches L1, L2 and L3 of the character strings of 2 and 3 are values proportional to the character size (vertical magnification) even if the same line feed amount (line feed 1) is designated. Similarly, the inter-character intervals P1, P2, P3 of the character strings of character sizes 1, 2, 3
Is a value proportional to the character size (horizontal magnification) even if the same character spacing of 2 (6 dots) is designated.

FIG. 9 shows a print example corresponding to the contents (a part) of the document area 21 and the line modification area 22 when a line feed O is used to shade half-width characters and quadruple-width characters. In this example,
The shaded pattern is independently prepared as one character. In this case, the character code A is prepared in the first row and the first column in the document, and the shaded code is prepared in the second row and the first column.
For example, if line feed O is specified on the first line for the line pitch and double-byte characters are specified for the line size on the first line and the second line, the line A of the same size is superimposed on the character A printed by the printing on the first line. The shaded pattern is printed by printing the second line.
If shading is applied to a large number of character strings, a string of shading codes may be input and the spaces between the characters may be set to zero.
The same applies to the case of enlarged characters such as quadruple characters.

FIG. 10 shows a print example when a superscript character and a subscript character (in full-width characters) for a quadruple-width character is created by using line feed B, line feed H, etc. ).

When the CPU 10 executes the paper feed of step S42 or step S43, the number of print lines M is reduced by -1 (step S4
4), it is determined whether M becomes 0 (step S4)
Five). If M is not 0, there are still document lines to be printed, so the CPU 10 increments the print line pointer K by 1 to advance to the next document line (step S46), and then step S46.
Return to step 13. On the other hand, if M is 0, the CPU
In step S47, it is determined whether the print stop is designated by the line modification information of the Kth line (step S47). If the print stop is designated, the CPU 10 returns to the process of step S4,
Display the print menu. This allows the operator
The printing ribbon used for printing by the printer 43 can be exchanged to change the color type, the left margin value, and the vertical / horizontal printing settings can be changed. On the other hand, if the print stop is not designated, the CPU 10 determines the print end of the document in the document area 21 and ends the print control.

[Effects of the Invention] As described in detail above, according to the present invention, when a character that does not fall within the print boundary or the specified print range occurs due to the designation of enlargement of the character size or the character-to-character spacing, the corresponding character is printed. Can be selectively prohibited.
