Abstract

PURPOSE:To permit different sizes of letters to be printed on the same line and also expanded letters to be lap-printed by feeding papers to the opposite directions corresponding to printed letter sizes on the printed line. CONSTITUTION:The number of printing dots of a printer is 24 dots which coincide with the vertical dot number of em-letters. If the pattern of letters in the P row of K line is expanded letter pattern composed of 48X48 dots, in case vertical 24 dots are one-sliced, CPU is set up intially to slice number 0 for printing by by operation of printing head for one-line. The slice number is then set to +1, and printing paper is sent forwardly only for vertical dots of em-letters so that between slices becomes 0. When printing of letter row of K line is ended, line feeding of line feeding amount T is realized by CPU. When T<0, reversely directed paper feeding for the absolute value of T is made for printer. Line feeding of a line interval of 0 can thus be realized and the first letter row and the second letter row can be connected without space.

).

Next, the operation of one embodiment of the present invention will be explained.

In this embodiment, print control by cpu io is as follows:
This is carried out according to the flowchart shown in FIG.

When the operator wants to print the input document (or edited document), the operator presses the [mark M] key (actually [mark]) on the keyboard 33.
[Function] key and [\] primary key. CPU 10
If the key is manually operated, it is checked whether or not the [Print] key was manually operated (step S1); if no, other key manual processing (step 82) is performed; if YES, step S3 is executed. In this step S3, a print line pointer K indicating the document line to be printed from now on.

And the next middle a start line N indicating the first line of the document lines to be printed in the next print cycle is initialized to 1, respectively. Next middle start line N, print line pointer is R
It is set in registers 51 and 52 secured in AM20.

When CPU IO executes step S3, it displays a print menu (step S4). In this state, the operator can specify the left margin and [/horizontal printing. After this, the [Select] key is operated, and the CPU 10
(step 85), the CPU 10 uses the RAM
The line modification information of the Nth row of the row modification area 22 secured in the row modification area 20 is referred to, and the printing stop flag is checked (step 86). Then, the CPU 10 determines whether or not printing stop is specified by the print stop flag (step 87).
The document line within 1 is checked (step S8). Then, the CP Ll 10 determines whether or not the corresponding document line has no character code, that is, whether or not it is the document END (step 89). If the statement is not 5END, 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. From, CP LJ 1
0 increases N by 1 and sets a new next print start line N (
Step 510). When step S10 is executed, the process returns to step S6, and the above processing is performed for the newly set Nth line (determination of presence or absence of print stop designation, determination of document END)
will be carried out.

Now, if the CPU 10 determines in step s7 that printing stop of the Nth line is specified, or in step S
When the document END is determined in step 9, an operation of N-1 is performed,
The number of print lines M indicating the number of lines of the document to be printed in the current print cycle (note that this is not the number of lines as a print result) is determined (step $11).

This number of print lines MG is set in a register 53 secured within the tRAM 20. Next, the CPU 10 determines whether M is 0 (step 812), and M-0
If so (because there are no print lines), the CPUIO ends print control. On the other hand, if it is not M-0, CP
In order to prepare for printing, the U 10 first extracts the line modification information of the first line indicated by the print line pointer from the line modification area 22 (step 813). Next, cpuio executes step 814 to determine the actual line feed amount T.

In step 814, based on the character size information in the line modification information, the number of vertical dots m and the number of horizontal dots m' of a character of the size specified by the information are determined, for example, from a character size table prepared in the ROM 12 (see Fig. (not shown), 24
Magnification based on double-width characters of x24 dots (vertical magnification m/
24. The lateral magnification m-/24) is determined. Similarly, based on the line pitch information in the line modification information, line feed amount (n/120. unit; inch) based on the full-width character specified by the same information.
For example, the line feed amount table prepared in ROM 12 (
(not shown). Then, by multiplying the line feed amount n/120 by the vertical magnification m/24, the actual line feed I for the character string of the specified character size (character magnification)
T is determined and the register 54 is secured in the RAM 20.
is set to At this time, line break IT may be determined by further multiplying by a proportionality constant k.

Note that the reason why the line feed amount indicated by the line pitch information is expressed in the format n/120 is because the paper feeding unit of the printer 43 in this embodiment is 1/120 (inch).

Therefore, n/120 indicates paper feed by n units. Similarly, the line feed amount T (m·n/24)/120 indicates line feed paper feeding by (m−n/24) units proportional to the designated magnification. However, n/120. (m-n/24)/120 is not an integer, so actually the n part of n/120,
Only the (m-n/24) portion of (m-n/24)/120 is stored in the table in the ROM 12 and the register 54 in the RAM 20.

In this embodiment, n has a plus/minus sign indicating the line feed direction, as is clear from FIG.

Note that the above m, m-, and n can be set in advance in a print control program instead of in a table.

Now, the number of dots in the print head of the printer 43 is 24 dots, which corresponds to the number of vertical dots in a full-width character.

For this reason, character strings such as enlarged characters having more than 24 vertical dots cannot be printed by driving the print head for one line, and must be printed in several batches. Therefore, in this embodiment, the number S of slices of the character (character pattern) to be printed is determined, assuming that 24 vertical dots are one slice (step 515). This number of slices S is determined based on the specified character magnification and furthermore, the character form, but here, for simplicity, it is assumed that it is determined from the magnification m/24. However, m/
If 24 is not an integer, the integer greater than and closest to that value is used. For example, m-32 (
If size 2 is specified), S-2 is adopted.

The number of slices S obtained in step S15 is RAM
It is set in a register 55 reserved in 20. C.P.
When U 10 completes step S15, it initializes to 0 a slice number pointer L indicating a slice to be printed in one line of print head driving operation. L-0 indicates the first slice.

Next, the CPU 10 first prepares in the ROM 12, for example, a character spacing (n' dot) based on the full-width character specified by the same information, based on the character spacing information in the line modification information of the first line. n
By multiplying ' by the horizontal magnification m'/24, the actual character spacing U (unit: dots) proportional to the magnification is determined (step 517). This character amount interval U is set in a register 61 secured within the RAM 20.

When CP tJ 10 executes step S17, RAM
20 (step 818).

Then, c p u io initializes the in-line character pointer P to 1 (first character digit), which specifies the character position (character digit) of the next character to be extracted from the character string in the th line (step 519). . This character pointer P is set in register 58 in RAM 20.

Next, CP tJ 10 is set to the print line pointer and the character specified by the character pointer P (P-1> (row 1, column P)
The character pattern of slice L (L-0) of
In order to write in the print image area 26 within the print image area 26, a write start address Q within the print image area 26 is determined taking into account the left margin (step 520). This write start address Q
(Relative address within the print image area 26) will be 3d if a left margin for d dots is required, as 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 shows the configuration of the print image area 26 when the print head is driven for one line (one slice print area).
It is schematically shown corresponding to. As is clear from the figure, addresses O to 3 of the print image area 26 (print image area 26
The inner relative address) corresponds to each area obtained by dividing the 0th dot row (24 dots) of the print area for one slice into three parts in units of 8 dots (1 byte). In general, addresses 3n and 3n+1.3n+2 (relative addresses within the print image area 26) of the print image area 26 correspond to the nth dot row (24 dots) of the print area for one slice in units of 8 dots (1 byte). It corresponds to each area divided into three. Therefore, if a left margin of d degrees is required, the write start address Q will be <3d as described above.

When CPU IO executes step 820, it first obtains the write end address R in the print image area Fa26 of the character pattern of the slice L of the character in the Pth column in the 1st row (Snotube 521). This write end address R is slice L
In this example, where the number of horizontal dots is m-, it is obtained by adding 3 (m=-1) to the write start address Q. The write end address R is set in the register 60 in the RAM 20.

After finding the write end address R, cpu io compares the same address R with the write end address LE, and determines whether R is larger than LE (step 52).
2). This final write address LE indicates the first eight dots of the final dot row (ie, print boundary) of one slice printing area, as shown in FIG. 5, for example. Therefore, from step S22, it can be determined in advance whether a part of the character pattern of the slice L of the character in the P-th row and the P-th column exceeds the printing boundary.

The significance of step 822 above will be specifically explained with reference to FIG. 6 and FIGS. 7(a) and 7(b). now,
Assume that the character pattern of the character in the Pth row and the Pth column is an enlarged character pattern with a 48x48 dot configuration as shown in Figure 6, due to the specification of the line pitch information (size 5) in the corresponding row modification information. . Now, consider a case where, for example, a character pattern of slice O in the enlarged character pattern shown in FIG. 6 is written in the print image area 26. If the write end address R for the character pattern of slice O (the same applies to the character pattern of slice 1) is not greater than the end write address LE, the storage state of the pattern in the print image area 2G will be as shown in FIG. 7(a). Therefore, when the contents of the print image area 26 are printed, the above pattern will not exceed the print boundary. On the other hand, if the writing end address R for the character pattern of slice 0 (the same applies to the character pattern of slice 1) is larger than the own end address LE, the storage state of the pattern in the print image area 26 is as shown in FIG. 7(b). When the contents of the print image area 26 are printed, a portion of the above-mentioned pattern exceeds the print boundary, resulting in a portion of the character pattern being missing. That is, in step 322, it is determined in advance whether or not the enlarged character pattern will be printed without being missing when the enlarged character pattern is unconditionally written in the print image area 26. Note that the final write address LE is not limited to the print boundary fixed to the apparatus as described above, but may correspond to a print range specified by the operator, such as the right margin, for example. In this case, step 822 determines in advance whether or not the enlarged character pattern will be printed without exceeding the print range when the enlarged character pattern is unconditionally written in the print image area 26.

If the determination in step 822 is No, cpuio extracts the character (character code) in the Pth column of the 1st row specified by the print line pointer and character pointer P from the document area 21 (Step 523); Determine whether the character code is a line feed code (no pattern writing required) (
Step $24). If it is not a line feed code, it is necessary to write a pattern, so set the character pointer P by +1.
After proceeding to the next character position (step 525), the character pattern corresponding to the character code taken out at step 823 is taken out from the character pattern area 16 in the ROM 12 (step 826). The character pattern stored in the character pattern area 16 is a full-width character pattern composed of 24×24 dots (72 bytes). The character pattern taken out from the character pattern area 16 is temporarily stored in a predetermined one character storage area (not shown) in the RAM 20.

When CPU IO executes step 826, it first determines whether or not a change in character size or character form is requested based on the line modification information of the line, that is, whether or not conversion of the character pattern is required ( step 527).

If pattern conversion is necessary, the CP LJ 10 sequentially converts the character pattern in the one character storage area (i.e., the original character pattern) into a character pattern of a specified size or form (step 828), and the pattern conversion is performed. If step 828 is not necessary, skip step 828, and then select the character pattern of the slice number (i.e. slice L) indicated by slice number pointer L (if step 328 is skipped, it is a full-width character, so the character pattern in the 1-character storage area is (which becomes a character pattern) are sequentially written in the area starting from the relative address in the print image area 26 indicated by the write start address Q (step 529).

When CPU IO executes step 829, by adding three times the character interval U (dot) to the write end address R, the write start address Q is set to start writing of the next character (one slice). The same address Q is updated to indicate the address (step 530). This achieves the character spacing of U dots. The character amount interval U is obtained in step 817 as described above,
The character spacing is not based on the full-width characters specified in the font size information, but is obtained by multiplying this specified character spacing by the magnification (horizontal magnification) (specified in the font size information), that is, it is proportional to the magnification. This is the actual character spacing. Therefore, in this embodiment, while specifying the character spacing based on the image of full-width characters, the character spacing that matches the actual character size is automatically realized.

After executing step 830, the CPU 10 increments the number of printed characters V by 1 (step 531), and determines whether ■ has become 0 (step 532). If ■ is not O, c p u io returns to step 821 assuming that an unprocessed character remains in the first line.

On the other hand, if it is V-0, the CPU 10 assumes that all the characters in the first row have been extracted and the corresponding character pattern (the character pattern of slice L) has been written in the print image area 26, and the CPU 10 performs step 833. Starting from , the process proceeds to a process centered on controlling the printer 43 for printing the first line. The process starting from step 333 is performed even if ■=O, if the determination in step 822 is YES (that is, if the self-write end address R is greater than the final write address LE), or if the determination in step 324 is YES. (i.e., when the character code extracted from the document area 21 is a line feed code), and also when printing of the corresponding character in the P-th column in the corresponding row is prohibited or unnecessary.

c p u io first determines whether the character pointer P indicates 1, that is, whether step 825 of adding 1 to P has not been executed even once (step 53
3). If it is not P-1, the CPU 10 determines that the first character of the line is not a line feed code (that is, it 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 contents of the print image area 26 (step 534). Next, the CPU 10 clears the print image area 26 (step 835), L, and then subtracts the number of slices S by 1 (step 836). Then, cpu io determines whether the number of slices S is 0, that is, whether printing of the character string in the first row has been completed (
Step 531).

If the determination in step 837 is No, c p u io
first determines that the printing of the first line has not been completed, first increments the slice number pointer L by 1, and specifies the slice number of the next slice to be printed (step 838).
. The c p u io then controls the printer 43 so that the next slice is connected to the slice printed in step 334 (that is, so that the distance between the slices is O).
The printing paper is fed in the forward direction by the length of the print head (the length of a vertical dot of a full-width character) (step 539). As described above, the paper feeding unit of the printer 43 is 1/120 (inch), the dot configuration of the print head is 24 dots, and the three dots are 2/120 inch. Therefore c
p u io is 16/1 in step 839
This causes the printer 43 to feed the paper in the forward direction by 20 (inches). After executing step 839, c p u io returns to step 818 and performs processing for printing the next slice for the same character string in the first line as the previous time.

On the other hand, if the determination in step 837 is YES, that is, if the printing of the character string in the first line is completed and the number of slices S becomes O, the CPU 10 executes the L The value obtained by multiplying by 16/120 (i.e., the amount of paper feed required to print the character string in the first line) is T, i.e. (m-n/24)
/120 and set the result as the line feed amount T (
step 540).

This newly obtained absolute value of the bottom of the line feed indicates the paper feed I (inch) for the line feed paper that should be carried out after printing the first line, and the sign (plus/minus sign) indicates the paper feed direction. shows. As is clear, when the second line is full-width characters specified (size 1), L remains 0 (that is, the printing paper feed in step 839 is not executed), so the newly determined T is It matches the king requested in 814.

When the CPU 10 executes step 340 or determines YES (P-1) in step 833, the CPU 10 determines whether line feed IT is 0 or more, that is, if the paper feed is in the forward direction, in order to determine the paper feeding direction. whether there is or not).
step 541). Note that the determination in step S33 is YE.
In the case of S, the printing execution in step 834 is skipped because the first character of the line is a line feed code and becomes a complete line feed.

CP tJ 10 causes the printer 43 to forward paper feed by 1 inch if ■≧0 (step 54).
2) If T<O, the printer 43 is caused to feed the paper in the reverse direction by the absolute value of T (step 843). As a result, the actual line feed pitch is determined by the ratio of the line feed pitch and the character size (number of vertical dots) of the printed characters on the second line to the line pitch (line feed pitch) based on the full-width character specified by the line pitch information. This is realized so as to match the ratio between the number of vertical dots and the number of vertical dots of a full-width character. That is, in this embodiment, while specifying the line pitch (line feed pitch) based on full-width characters, it is possible to realize a line pitch proportional to the size of characters specified by the character size information. Note that the determination in step 833 is YES.
In this case (that is, in the case of a complete line break), since printing is not executed, T obtained in step 314 is used as is.

Now, in this embodiment, the line pitch information is B, O,
H, E, 1 to 4 911 are prepared n-c (3rd
(see figure).

Line feed B (reverse line feed, back line feed) specifies a line feed in the opposite direction by 8/120 (inch) based on full-width characters. In this case, the paper feed amount after printing the character string in the first line is calculated from the line pitch (minus value) for the character string of the specified character size, which is obtained by multiplying -8/120 (inches) by the vertical magnification. It is the absolute value of the value obtained by subtracting the paper feed amount required to print (the total paper feed amount of paper feeds performed to print the same character string), and the subtraction result is negative in the paper feed direction. Therefore, it is in the opposite direction. Therefore, when line feed B is specified, a reverse line feed of 1/2 the character size specified by the character size information is realized.

Line feed 0 (line pitch O) specifies line feed amount O.

In this case, the paper feed amount after printing the character string in the first row is the paper feed amount required to print the same character string (the total paper feed amount of the paper feeds performed to print the same character string). corresponds to the absolute value,
The paper feed direction is the opposite direction.

Therefore, when a line feed O is specified, a line pitch of 0 (0 line feed) is achieved regardless of the character size specified by the character size information. In addition, when the number of vertical dots is 24,
Since the total paper feed amount during printing is 0, the paper feed amount after printing is also O.

Line feed H (half line feed, half line feed) specifies that a line feed is to be made in the forward direction by 8/120 (inch) when using full-width characters as the standard. In this case, the paper feed amount after printing the character string in the first line is calculated from the line pitch for the character string of the specified character size, which is obtained by multiplying +8/120 (inches) by the vertical magnification.
The absolute value of the value obtained by subtracting the paper feed amount required to print the same character string (the total paper feed amount of paper feeds performed to print the same character string), and the paper feed direction is the result of the subtraction. The direction is indicated by the sign (positive/negative). Therefore, when a line feed H is specified, a forward line feed (half line feed) for 172 characters of the character size specified by the character size information is realized.

Line feed K (ruled line feed, line feed by one character) specifies that a line feed is to be made in the forward direction by 16/120 (inches) based on full-width characters. In this case, the paper feed amount after printing the character string in the first line is determined by the line pitch for the character string of the specified character size, which is obtained by multiplying +16/120 (inches) by the vertical magnification. The value obtained by subtracting the paper feed l (the total amount of paper feed carried out to print the same character string), that is, 16/120 (inch), is the paper feed direction, and the subtraction result is correct for the paper feed direction. Therefore, it is a forward direction.

In this case, the specific paper feed amount is the character size of the magnification 1, that is, 16/120 (inches) when the vertical magnification is an integer, and is a fixed amount. On the other hand, if the vertical magnification is not an integer,
The forward paper feed surface corresponds to the character size of the magnification indicated by the decimal part of the vertical magnification.

Therefore, when a line break K is specified, a line break with only character valves of the font size specified by the character size information, that is, a line break with a line spacing of O is realized.

For this line break, since the line spacing can be set 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 that follows the same character string. Since it is possible to connect lines without gaps, it is suitable for creating enlarged ruled lines (particularly vertical ruled lines), for example. In addition,
When creating horizontal ruled lines, the character spacing may be set to O.

Also, line feed E (English line feed) specifies a line break in the forward direction by 20/120 (inches) based on full-width characters, and line feed 1.2.3.4 specifies line feed in the forward direction by 20/120 (inches) when based on full-width characters. 30/120.40/120.45/120.6
Specifies forward paper feed of 0/120 <inch).

The above specific examples are shown in FIGS. 8 to 10.

FIG. 8 shows an example of document printing when the same values are specified for the character spacing and line pitch (line feed amount) for each document character string, but different values are specified for the character size. This is shown corresponding to (part of) the contents of the line modification area 22.

In Fig. 8, the line break pitches Ll, L2, and L3 of a character string with a character size of 1.2.3 are different from the character size (vertical magnification) even though the same line feed amount (line feed 1) is specified.
The value is proportional to . Similarly, the character spacing Pi, P2, and P3 for character strings with character sizes 1 and 2.3 are proportional to the character size (horizontal magnification) even if the same character spacing 2 (6 dots) is specified for each character string. value.

FIG. 9 shows an example of printing when a line feed O is used to shade full-width characters and quadruple-width characters, corresponding to the contents (parts) of the document area 21 and line modification area 22. In this embodiment, the hatching pattern is prepared independently as one character. In this case, prepare the character code A for the first row and first column of the document, and the shading code for the second row and first column, and for the line pitch, for example, specify line break O in the first line, and set the font size. When full-width characters are specified in the first and second lines, a half-width pattern of the same size is printed in the second line, overlapping the character A printed in the first line. If you want to shade a large number of strings,
All you have to do is input a string of shading codes and set the character spacing to 0. The above also applies to enlarged characters such as quadruple-width characters.

The tenth reason is that the contents of the document area 21 and line modification area 22 (partially ).

Now, cpuio does step 842 or step 84.
When the paper feed of 3 is executed, the number of print lines M is decreased by 1 (step 844), and it is determined whether M has become O (step 545). If M is not O, there are still document lines to be printed, so the CPU 10 moves the print line pointer K
After adding +1 to the next document line (step $46),
The process returns to step S13. On the other hand, if M is O, the CPU 10 first determines whether or not printing stop was specified in the line modification information of the th line (step 547).
. If printing stop is designated, the CPU 10 returns to step S4 and displays a print menu. This allows the operator to change the color type by replacing the print ribbon used for printing by the printer 43, change the left margin value, and change settings for vertical/horizontal printing.

If print stop is not specified for this, CP
The U 10 determines whether printing of the document in the document area 21 is finished;
End print control.

[Effects of the Invention] As detailed above, according to the present invention, pitch 0 is included as one of the line feed pitch values that can be selected and specified, and when pitch O is specified, the print character size of the corresponding print line is By feeding the paper in the opposite direction, the print start position of the next print line can be returned to the print start position of the corresponding print line regardless of the character size, making it possible to print characters of different sizes on the same line, Furthermore, since enlarged characters can be printed on top of each other,
A variety of printed documents can be created.
