Abstract

PROBLEM TO BE SOLVED: To provide the facsimile equipment by which facsimile data are printed out so as to be contained within a print range of a single paper sheet in the longitudinal direction in the case of using the single paper sheet. SOLUTION: The facsimile equipment is provided with a paper discrimination means (S8) that discriminates whether a print sheet is a single paper sheet or a continuous paper sheet and with a print data generating means that converts facsimile data into print data so that all dot numbers of facsimile data in the longitudinal direction is in matching with all dot numbers of a single paper sheet depending on the longitudinal direction dot density standardized in advance in a print means and on a length of the single print paper sheet in the longitudinal direction when the paper discrimination means discriminates the paper to be the single paper sheet. On the other hand, when the paper discrimination means discriminates the paper to be a continuous paper sheet, the print data generating means generates print data by converting the facsimile data so that the longitudinal direction dot density standardized in advance in the print means is obtained from the print density in the longitudinal direction of the facsimile data. Print data generated by the print data generating means are printed out by the print means (S09-S12).

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus having, for example, a printing means and capable of switching between cut-sheet paper and continuous paper during reception.

[0002]

2. Description of the Related Art A small-sized facsimile apparatus is provided which has a roll paper holding means for holding roll paper for recording at an outer position of a facsimile main body and can use either a cut sheet or a roll paper at the time of reception. JP-A-7-203092
No. has been proposed.

This apparatus has an insertion port and a discharge port on the upper surface of a main body, and a roller for feeding a document and a recording sheet is provided in the middle of a substantially U-shaped transport path connecting the insertion port and the discharge port. A line thermal head is provided so as to face the lower end of the roller, and a reading unit is provided downstream of the line thermal head in the substantially U-shaped conveyance path so as to face the roller. In addition, the insertion slot and discharge slot are used not only for inserting and discharging cut sheet paper and roll paper, but also for inserting and discharging originals for transmission or copying. ing.

However, this is a small facsimile apparatus, and uses a line thermal head for facsimile as a printing means. Since the line thermal head is formed by arranging the thermal elements in accordance with the width of the paper, a high-density one must increase the dot density by increasing the number of thermal elements, so that it must be expensive. Therefore, a line thermal head for a facsimile generally uses a low-density one, and the line thermal head is not suitable as a normal printer connected to a personal computer or the like in terms of print quality.

[0005] By the way, in sending and receiving faxes,
When the transmission / reception state is established, the receiving side sends the receiving side printing paper information such as A4 standard size or B5 standard size to the transmitting side, and the transmitting side matches the printing paper information specified by the receiving side. Send in data format.
Generally, before sending data of each page, a header such as date, time, page number, etc. is inserted as a special description of the fax.

Accordingly, the print data of one page is increased by an amount corresponding to the insertion of the header.
When printing on standard size cut sheet paper, the end of the document may not be printed on the receiving side.

[0007] The size of A4 standard size single-sheet paper is 210 mm wide by 296 mm high, and the standard format of fax data in the A4 standard size has a horizontal dot density of 209 (dot / inch) (hereinafter referred to as "dot / inch"). , Dpi), and has a horizontal dot density of 97.79 (dpi) and a vertical dot density of 296 mm.
There is a minute.

On the other hand, in a normal serial printer, the dot density in the vertical and horizontal directions is 180 (dpi).
The printing range of the standard A4 size is 203.2 mm in width, and is smaller than 296 mm in vertical because of the non-printable area of the printer. For example, vertical 261mm
It is.

Therefore, since the vertical print density of the printer is higher than the vertical print density of the standard fax data,
Characters and graphics are reduced in the vertical direction, and the standard fax data is 296 mm long and exceeds the printer's vertical print range of 261 mm, so that the end of the fax data does not enter the printer's print range. Since the fax data is not printed, there is a drawback that the fax data cannot be printed by a normal printer in the standard format.

[0010]

Next, a description will be given of the creation of print data for cut-sheet paper from fax data. In this embodiment, the cut sheet is of A4 fixed size.

In the standard format of fax data of A4 fixed size, the horizontal dot density is 209 (dpi), which is 210 mm in width. Therefore, the total number M1 of the fax data in the horizontal direction is M1 = (209 / 25.4 mm). ) × 21
It is determined at 0 mm and is approximately 1728.

On the other hand, the horizontal dot density of the printer unit 4 is 180 (dpi), and the printing range in the A4 standard size is 203.2 mm in width. M2 = (180/2
5.4 mm) × 203.2 mm = 1440.

In the preparation of print data for cut sheet paper, the total number of dots in the horizontal direction of fax data M1 = 172
8 is the total number of dots M2 = 14 in the horizontal direction of the printer unit 4.
Convert to 40. That is, conversion is performed at a conversion rate α1 that satisfies M1 × α1 = M2. Conversion rate α1 = M2 / M1 = 1440 /
1728 = 83.33 = 5/6, and all the horizontal dots of the fax data are compressed by a factor of 5/6.
As a result, the facsimile data is converted so as to fit in the horizontal printing range of the cut sheet.

FIG. 2 is a conceptual diagram showing horizontal compression of facsimile data performed in the case of cut sheets in this embodiment. More specifically, all the dots of one line in the horizontal direction of the facsimile data are performed in units of 6 dots, and the first to fourth dot data before the conversion are directly converted from the first dot data after the conversion. The dot data is sequentially transferred as the fourth dot data, and the logical OR of the fifth dot data and the sixth dot data before the conversion is obtained.
Is transferred as the fifth dot data after conversion. As an example, six dots before conversion are “1011”
01 ”, 5 dots after compression conversion are“ 1 ”.
In this manner, the compression of 5/6 times is repeated for all the dots of one line in the horizontal direction of the fax data, that is, for 1728 dots.

In the standard format of fax data in the A4 fixed size, the vertical dot density is 97.79 (d).
pi), the total number of dots N1 in the vertical direction of the fax data is N1 = (97.79 / 25.
4 mm) x 296 mm = 1139.6, which is almost 1140
It is.

On the other hand, since the vertical dot density of the printer unit 4 is 180 (dpi) and the printing range of the A4 fixed size is 261 mm in height, the total number N2 of dots in the vertical direction of the printer unit 4 is N2 = (180/25.
4 mm) × 261 mm = 1849.6, almost 1850
It is.

In the preparation of print data for cut sheet paper, the total number of dots in the vertical direction of fax data N1 = 114
0 is the total number of dots in the vertical direction of the printer unit N2 = 18
Convert to 50. That is, conversion is performed at a conversion rate β1 that satisfies N1 × β1 = N2. Conversion rate β1 = N2 / N1 = 1850 /
1140 = 1.623, which is approximately 13/8, and all dots in the vertical direction of the fax data are enlarged 13/8 times. As a result, the facsimile data is converted so as to fit in the printing range in the vertical direction of the cut sheet.

FIG. 3 is a conceptual diagram showing the enlargement of the facsimile data in the vertical direction which is performed in the case of the cut sheet in this embodiment. More specifically, the data of each line that has been compressed by a factor of 5/6 by the horizontal conversion is performed in units of eight lines, and the first line data before the conversion is the first and second data after the conversion. It is transferred as line data, the second line data before conversion is transferred as third and fourth line data after conversion, and the third line data before conversion is transferred as fifth line data after conversion. , 4 before conversion
The sixth line data is transferred as sixth and seventh line data after conversion, the fifth line data before conversion is transferred as eighth and ninth line data after conversion,
The 6th line data before conversion is transferred as 10th line data after conversion, the 7th line data before conversion is transferred as 11th and 12th line data after conversion, and the 8th line data before conversion is Is the converted 13 data
Transfer as the line data.

In this way, the expansion of 13/8 times is repeated for all the line data which has been subjected to the horizontal compression of 5/6 times, that is, 1140 lines. As a result, the print data for cut sheet paper is 1140 × (13/8) = 185.
Three lines are created.

Next, creation of printing data for continuous paper from fax data will be described. Normally, in fax communication, data described within a range of 3.5 mm inward from both left and right sides of 210 mm in width in the A4 standard size is not guaranteed. In the conversion of the cut sheet described above, the full scale of 210 mm in width was converted to be printable, and the conversion was performed so that the data of the left and right areas, which were not guaranteed, could be printed and displayed. Is converted for the purpose of printing fax data at the same size because there is no restriction on the printing paper in the vertical direction. For this reason, the size of a character or a figure does not change only by performing conversion so as to match the dot density for a certain length.

In the standard format of fax data in the A4 fixed size, the horizontal dot density is 209 (dpi). On the other hand, the horizontal dot density of the printer unit 4 is 1
80 (dpi).

In preparing print data for continuous paper, the horizontal dot density of the facsimile data is converted to match the horizontal dot density of the printer unit 4. In other words, the conversion is performed at a conversion rate α2 of 209 (dpi) × α2 = 180 (dpi). α2 = 0.947, and the compression conversion is performed with approximately 9/10.

FIG. 4 is a conceptual diagram showing horizontal compression of facsimile data performed in the case of continuous paper in this embodiment. More specifically, all the dots of one line in the horizontal direction of the facsimile data are performed in units of 10 dots, and the first to eighth dot data before conversion are directly converted from the first dot data after conversion. The dot data is sequentially transferred as dot data up to the eighth,
The result of the logical OR of the tenth dot data and the tenth dot data is transferred as the converted ninth dot data. In this way, the compression of 9/10 times is repeated for all the dots of one line in the horizontal direction of the fax data, that is, for 1728 dots.

In the standard format of fax data of A4 fixed size, the vertical dot density is 97.79 (d
pi). On the other hand, the vertical dot density of the printer unit 4 is 180 (dpi). In order to match the dot density in the vertical direction, conversion is performed at a conversion rate β2 of 97.79 × β2 = 180. Also in this case, the size of the characters and figures does not change. Conversion rate β2 = 180 / 97.79 = 1.8
In step 4, enlargement conversion is performed as approximately 11/6.

FIG. 5 is a conceptual diagram showing the enlargement of the facsimile data in the vertical direction performed in the case of continuous paper in this embodiment. Specifically, 9/10 is obtained by horizontal transformation.
The data of each line that has been double-compressed is performed in units of 6 lines, and the first line data before conversion is 1 line data after conversion.
Transfer as the second and second line data,
The third line data is transferred as the third and fourth line data after conversion, the third line data before conversion is transferred as the fifth and sixth line data after conversion,
The fourth line data before conversion is transferred as seventh and eighth line data after conversion, the fifth line data before conversion is transferred as ninth and tenth line data after conversion, and Is transferred as the 11th line data after the conversion. In this way, for all the line data compressed 9/10 times,
That is, the magnification of 11/6 times is repeated for 1140 lines. As a result, the printing data for continuous paper is 1140
× (11/6) = 2090 lines are created.

Next, the print data creation processing performed by the CPU 65 provided in the facsimile control unit 64 will be described. FIGS. 6 and 7 are flowcharts showing the main routine of the print data creation processing stored in the ROM 67. The print data creation process is performed when the fax data is completely received by the CPU 65 in the fax control unit 64 of FIG.
The processing is started when the received fax data is stored in the received fax data storage area of the AM 68.

The CPU 65 first determines the counters DC, LC1, LC2, n, and C1 required for the stamp data creation processing in the processing of steps S01 to S05.
To the initial value. In step S01, the dot counter DC is set to zero. Dot counter DC
Is a counter used to count the number of dots in one line in the horizontal direction of the fax data. In the case of single-sheet, the counter is used for performing horizontal compression processing every 6 dots.
In the case of continuous use, the horizontal compression process is performed in units of 10 dots, and the count value is increased by 10 and the count value is compared with the number of dots 1728 for one line.

In step S02, the line counter LC1 is set to 0. The line counter LC1 is a counter used to count the number of lines of the fax data before conversion stored in the received fax data storage area, and is incremented by one every time one line of the fax data is read out. The value is compared with the number of lines 1140 of the fax data before conversion for one page.

In step S03, the line counter LC2 is set to 0. The line counter LC2 is a counter used to count the number of lines of print data created by conversion, and the count value is 1
This is compared with the number of lines for the pass. In the present embodiment, since the print head 13 is formed of a serial of 64 dots vertically, the number of lines for one pass is 64.

In step S04, 1 is set to a creation data counter n. The creation data counter n is
This is a counter used to specify the order of the print data which is sequentially created in units of one line in the vertical enlargement process.

In step S05, the line identification counter C1 is set to zero. Line identification counter C1
Is a counter used to count the number of line data that becomes the line data when the line data subjected to the horizontal compression is vertically expanded in the vertical expansion process. In this case, the same vertical enlargement processing is performed cyclically in units of 8 lines, so that the count value is cyclically increased one by one within a range of 1 to 8, and in the case of continuous use, 6 lines are used. In order to perform the same vertical enlargement processing cyclically in units of, the count value is cyclically increased one by one within the range of 1 to 6.

After completing the processing of steps S01 to S05, the CPU 65 proceeds to step S06, reads one line of data from the received fax data storage area (step S06), and then responds to the reading of one line of data. Then, the value of the line counter LC1 is incremented by one (step S07), and the process proceeds to step S08.

In step S08, it is determined whether the current setting is to use cut sheet paper or continuous paper (roll paper). The processing of step S08 of the CPU 65 constitutes the paper discriminating means of the present invention. The paper mode of the paper used is stored in the RAM 68, and the determination is made based on this.

First, a description will be given of a process of creating print data in a case where it is determined in the determination process of step S08 that the sheet to be used is a single sheet. in this case,
After the determination in step S08, the CPU 65 proceeds to step S09.
The processing shifts to the subroutine of the single-sheet horizontal compression process represented by.

FIG. 8 is a flowchart showing a subroutine of the single-sheet horizontal compression process. As described with reference to FIG. 2, the CPU 65 reads the data from the read one-line fax data in units of 6 dots, compresses the data into 5 dots, and stores it in the conversion line data storage area of the RAM 68 (step A01). The value of the dot counter DC to 6
The value is incremented (step A02), and it is determined whether or not the value of the dot counter DC has reached the number of dots 1728 for one line (step A03).

If the value of the dot counter DC has not reached the number of dots 1728 for one line, the CPU 65 returns to step A01. Hereinafter, when the value of the dot counter DC is 1
Steps A01 to A0 until 728 is reached.
Repeat step 3. The data compression is performed by reading and compressing the first to sixth dots of the line data.
In the next round, the line data is read from the seventh dot to the twelfth dot and compressed, so that the line data sequentially shifts to the rear in the unit of six dots. Also, when storing the compressed 5 dot data in the conversion line data storage area, the first to fifth dots are stored, and the next time the sixth to tenth dots are stored in the first dot. From 5
It is assumed that compressed line data is stored in such a way that it is stored after the dot.

Then, when the value of the dot counter DC reaches the number of dots 1728 for one line, the CPU 65 sets the dot counter DC to 0 (step A04), ends the subroutine of the single-sheet horizontal compression process, and ends the main routine. Return to. As a result, the compressed line data that has been compressed by a factor of 5/6 based on the one line of fax data read in step S05 is stored in the conversion line data storage area of the RAM 68.

The CPU 65 that has returned to the main routine after finishing the processing in step S09 proceeds to the subroutine of single-sheet vertical enlargement processing shown in step S10. FIG.
0 is a flowchart showing a subroutine of single-sheet vertical enlargement processing.

As already described with reference to FIG. 3, the line data to be created differs depending on the order of the converted line data before the vertical enlargement, ie, one line or two lines. If it is the 6th line and the 8th line, one line data is created, and 1, 2, 4,
For the fifth and seventh lines, two line data are created. The line number of the converted line data to be vertically expanded this time is identified by the current value of the line identification counter C1 described above.

When the CPU 65 starts the cut-sheet vertical enlarging process, the CPU 65 determines whether or not the value of the line identification counter C1 is three.
It is sequentially determined whether the value of the line identification counter C1 is 6 and whether the value of the line identification counter C1 is 8 (steps A10 to A12).

The first line for vertical expansion this time is the first line,
If it is any of the second, fourth, fifth and seventh, the CPU 65 proceeds to step A1
0, all of the steps A11 and A12 are determined to be false, and the process proceeds to step A13.

The CPU 65 increases the value of the line identification counter C1 by one (step A13), and then uses the compressed line data created in step S09 as the n-th line data specified by the value of the creation data counter n. The compressed line data created in step S09 is transferred and stored in the print data storage area of the RAM 68 as the (n + 1) th line data specified by the value of the creation data counter n + 1. The data is transferred and stored in the storage area (step A15), and the value of the created data counter n is increased by two in accordance with the number 2 of line data transferred and stored, and updated for the next line data transfer storage (step A16). ), The value of the line counter LC2 is also increased by two (step A17),
After returning to the subroutine of the single-sheet vertical enlargement process, the process returns to the main routine. In this case, two lines of print data are created for the one line of fax data read in step S05.

If one line to be vertically expanded this time is one of the third and sixth lines, the CPU 6
In step S5, the process proceeds to step A18, where the line identification counter
The value of 1 is increased by one (step A18), and step A
Move to 19.

Also, one line for vertical expansion this time is the eighth line.
If it is the first time, the CPU 65 proceeds to step A22 after the processing of step A12, and sets the value of the line identification counter C1 to 1 in order to cyclically perform the vertical enlargement processing of the line from the next time on (step S22). A22), and the procedure goes to step A19.

The CPU 65, which has proceeded to step A19,
The compressed line data created in step S09 is transferred and stored in the print data storage area of the RAM 68 as the n-th line data designated by the value of the created data counter n (step A19). , The value of the created data counter n is incremented by one and updated for the next line data transfer and storage (step A20), and the value of the line counter LC2 is also incremented by one (step A21). The subroutine of the vertical enlargement process is ended, and the process returns to the main routine. In this case,
With respect to the one line of fax data read in step S05, print data for one line is created. As a result of sequentially updating the value of the line identification counter C1 in the range of 1 to 8, 13 lines of print data are created. Step S
CPU 6 that has returned to the main routine after completing step 10
In step S5, the process proceeds to step S13.

The CPU 65, which has proceeded to step S13,
It is determined whether or not the value of the line counter LC2 has reached 64, that is, whether or not the print data created and stored in the print data storage area has reached one pass (64 lines) (step S13). ).

If the value of the line counter LC2 has not reached 64, the CPU 65 returns to step S06 again.
The next one line of data is read out from the received fax data storage area, and steps S07 and S08 are performed.
09 and the vertical enlargement process in step S10. Thereafter, until the value of the line counter LC2 reaches 64, the CPU 65 proceeds from step S06 to step S1.
0, the processing loop formed in step S13 is repeated, and print data is sequentially created and stored in the print data storage area.

Then, the value of the line counter LC2 is 64
, The print data created and stored in the print data storage area reaches one pass (64 lines). The CPU 65 proceeds to step S14, and transfers the print data for one pass created and stored in the print data storage area to the printer control unit 51 (step S1).
4).

When the print data for one pass is transferred, the printer control unit 51 temporarily stores the print data for one pass in the RAM 54 of FIG. 1 and prints the stored print data for one pass on the printing paper. Become.

After the processing in step S14, the CPU 65
The current value of the line counter LC2 is subtracted by 64, and then it is determined whether or not the value of the line counter LC1 has reached the number 1140 of lines of fax data for one page (steps S15 and S16).

If the value of line counter LC1 has not reached 1140, CPU 65 returns to step S06. Thereafter, until the value of the line counter LC1 reaches 1140, the CPU 65 proceeds from step S06 to step S1.
0 and a processing loop formed by step S13, and steps S06 to S10 and step S1.
The processing loop formed by steps 3 to S16 is repeated, print data is sequentially created and stored in the print data storage area, and when the created print data reaches one pass, it is transferred to the printer control unit 51. Then, printing is performed by the printer control unit 51.

Next, a description will be given of a process of creating print data in a case where it is determined in the determination process of step S08 that the used paper is continuous paper. In this case, after the determination in step S08, the CPU 65 proceeds to step S08.
The process proceeds to a subroutine for continuous horizontal compression processing indicated by reference numeral 11.

FIG. 9 is a flowchart showing a subroutine of the continuous horizontal compression process. As already described with reference to FIG. 4, the CPU 65 reads data in units of 10 dots from the read one-line fax data, compresses the data into 9 dots, and stores the data in the conversion line data storage area of the RAM 68 (step B01). Next, the value of the dot counter DC is increased by 10 (step B02), and the dot counter D is increased.
It is determined whether or not the value of C has reached the number of dots 1728 for one line (step B03).

If the value of the dot counter DC has not reached the number of dots 1728 for one line, the CPU 65 returns to step B01. Hereinafter, when the value of the dot counter DC is 1
Steps B01 to B0 until 728 is reached.
Repeat step 3. Data compression is performed by reading and compressing the first to tenth dots of the line data, and then reading and compressing the eleventh to twentieth dots of the line data the next time. The unit shall be shifted to the lower rank. When the compressed 9-dot data is stored in the conversion line data storage area from the first dot to the ninth dot, the next time the tenth to eighteenth dots are stored in the first dot. It is assumed that the compressed line data is stored in such a manner as to be stored at the position after the ninth dot.

When the value of the dot counter DC reaches the number of dots 1728 for one line, the CPU 65 sets the dot counter DC to 0 (step B04), ends the subroutine of the continuous horizontal compression process, and returns to the main routine. Return. As a result, based on the one line fax data read in step S05,
The compressed line data that has been doubled is stored in the RAM 68.
Is stored in the conversion line data storage area.

After returning to the main routine after finishing the processing in step S11, the CPU 65 shifts to the subroutine of the continuous vertical enlargement processing shown in step S12. FIG.
1 is a flowchart showing a subroutine of the vertical extension process for continuation.

As already described with reference to FIG. 5, when the converted line data before the vertical enlargement is the sixth line, one line data is created, and the first to fifth lines are created.
If it is a line, two line data are created.
The line number of the converted line data to be vertically expanded this time is identified by the current value of the line identification counter C1 described above.

When starting the continuous vertical enlargement process, the CPU 65 determines whether or not the value of the line identification counter C1 is 6 (step A10).

One line for vertical expansion this time is the first to
If any of the fifth, the CPU 65
Determines that the determination processing in step B10 is false, and proceeds to step B11. The steps B11 to B15 are sequentially performed to create two lines of printing data in the printing data storage area of the RAM 68, and to continuously enlarge vertically. After the processing subroutine ends, the process returns to the main routine. The processing in steps B11 to B15 is an algorithm equivalent to the processing in steps A13 to A17 in FIG.

Also, one line for vertical expansion this time is the sixth line.
If it is the first time, the CPU 65 determines that the determination processing in step B10 is true, and proceeds to step B16, and sets the value of the line identification counter C1 to 1 in order to cyclically perform the vertical enlargement processing of the line from the next time. Set and return (Step B
16), the processes in steps B17 to B19 are sequentially performed to create one line of print data in the print data storage area of the RAM 68, and the subroutine of the continuous vertical enlargement process is completed, and the process returns to the main routine. The processing in steps B17 to B19 is an algorithm equivalent to the processing in steps A19 to A21 in FIG. As a result of sequentially updating the value of the line identification counter C1 in the range of 1 to 6, printing data for 11 lines is created. The CPU 65 that has returned to the main routine after finishing the processing in step S12 moves to step S13.

The CPU 65, which has proceeded to step S13,
As in the case of single-sheet data, whether or not the value of the line counter LC2 has reached 64, that is, the print data created and stored in the print data storage area has reached one pass (64 lines). It is determined whether or not it has been performed. Until the value of the line counter LC2 reaches 64, the CPU 65 repeats the processing loop formed in steps S06 to S8 and steps S11 to S13, sequentially creates print data for continuation and prints the print data. It is stored in the storage area.

Then, the value of the line counter LC2 is 64
Is reached, the CPU 65 proceeds to step S14,
The print data for one pass created and stored in the print data storage area is transferred to the printer controller 51, and the print data for one pass is printed.

After the processing in step S14, the CPU 65
The current value of the line counter LC2 is subtracted by 64, and then it is determined whether or not the value of the line counter LC1 has reached the number of lines of fax data for one page 1140 (step S16).

If the value of the line counter LC1 has not reached 1140, the CPU 65 returns to step S06. Thereafter, until the value of the line counter LC1 reaches 1140, the CPU 65 proceeds from step S06 to step S0.
8 and the processing loop formed by steps S11 to S13, and steps S06 to S0
8. Steps S11 to S13 to S16
Is repeated, and successive print data is sequentially created and stored in the print data storage area. When the created print data reaches one pass, it is transferred to the printer control unit 51. , Printer control unit 51
To print.

Next, the processing of steps S16 to S19 will be described. The value of the line counter LC1 is 1
When the number reaches 140, that is, when the generation of the print data for the number of lines 1140 of the fax data for one page is completed, the CPU 65 proceeds to step S17.

Note that the total number of print data created from the time when the print data creation process is started to the time when the determination process in step S16 is determined to be true is 1853 in the case of a single-cut form as described above. In the case of continuous use, it is 2090 lines.

On the other hand, the print data transferred to the printer control unit 51 and printed is in units of 64 lines.
Lines = 28 lines, 61 lines, that is, print data for 61 lines remains in the print data storage area as a fraction, and in the case of continuous use, 2090 lines / 64
Lines = the remaining 32 lines, ie, 42 lines, that is, print data for 42 lines remains as a fraction in the print data storage area.

The processing from step S17 to step S19 is a processing for transferring the stamp data remaining as a fraction in the print data storage area to the printer control unit 51 in the size of 64 lines and printing. is there.

The CPU 65 stores the result obtained by subtracting the current value of the line counter LC2 from the line number 64 in the shortage line number calculation counter LC3 (step S17), and then stores the shortage line stored in the shortage line number calculation counter LC3. A blank line of only several minutes is added to the subsequent stage of the stamp data remaining as a fraction in the print data storage area to create print data for one pass (step S18), and the data for one pass created in step S18 is created. Is transferred to the printer control unit 51 to cause the printer control unit 51 to perform printing (step S19), and the print data creation process ends. That is, in the present embodiment, the CP
U65 and the print data creation processing shown in FIGS. 6 and 7 constitute the print data creation means.
