Description

  The present invention relates to a printing apparatus, a control method thereof, and a control program.

  Conventionally, there is a tape printer that prints a character string on a tape-shaped recording paper and creates a label to be attached to various articles.

  This tape printer includes a cassette mounting portion on which a cassette containing a tape as a medium on which printing is performed is mounted. The cassette mounting portion includes a thermal head for printing on the tape, and a tape between the thermal head and the thermal head. A platen roller that conveys the sheet and a cutter that cuts the printed tape are disposed.

  Incidentally, in a tape printer, printing may be interrupted in order to perform a predetermined process during printing. For example, when cutting the tape to ensure the margin set at the front of the character string to be printed, the temperature of the thermal head rises too much during printing, and in order to perform appropriate printing control, This is the case when cooling is necessary, or when the expansion processing of print data is performed during printing.

  When printing is interrupted, the thermal head and the drive motor for the platen roller are stopped while the platen roller is held at the printing position in order to prevent the tape from being displaced during a predetermined process. When the predetermined processing is completed, printing is resumed by controlling the thermal head and the drive motor for the platen roller.

  By the way, in a tape printer that can move the platen roller with respect to the thermal head and includes the platen roller driving means as described above, there is a possibility that the tape is sent when printing is interrupted and printing omission occurs.

  Conventionally, there has been known a technique for preventing the occurrence of printing omission by causing the drive motor to be reversely driven uniformly by a fixed angle when printing is interrupted (for example, a technique described in Patent Document 1). ).

  In addition, a technique is known in which, when printing is interrupted, a print line immediately before the stop of the tape is reprinted to prevent print loss (for example, a technique described in Patent Document 2).

  However, even when the above-described conventional technology is applied, depending on the pattern (state) of the print data, the thermal head and the ink ribbon may easily adhere to each other, and there is a possibility of inducing printing omission. all right. In addition, it is considered that there are various factors other than the adhesion between the thermal head and the ink ribbon as the cause of printing omission. For example, in Patent Document 2 described above, cutting the tape while printing is interrupted is described as one of the causes. Further, regarding the above-described adhesion, when the temperature change of the head is sufficiently small during the interruption, for example, the interruption time is relatively short, or the head temperature is kept constant by appropriately energizing the printing interruption. On the contrary, it is considered that the adhesion phenomenon between the thermal head and the ink ribbon hardly occurs when the treatment is performed. As described above, not only the print data pattern but also the print omission depends on the state of various print control data for controlling printing, such as the control of the cutter and the time for interrupting the printing to perform the predetermined processing. There was a risk of triggering.

Each engaging portion 18 is engaged with each cassette receiving portion 20 to be set at a predetermined position in the tape cassette housing portion 5.

  In FIG. 3, the print head 22 is disposed at a position that enters the print head insertion portion 17 of the tape cassette 10, and is pressed against the ink ribbon 14 at the start of printing. The platen roller 23 is disposed so as to face the print surface of the print head 22, and the ink ribbon 14 and the print-receiving tape 12 sandwiched between the print head 22 and the print-receiving tape 12 in the longitudinal direction.

Are controlled respectively.

  In this embodiment, the ink ribbon 14 is a thermal transfer type ink ribbon, and the print head 22 has a predetermined number of dot-like heating elements in the vertical direction, that is, along the width direction of the ink ribbon 14 and the printing tape 12. Thermal heads arranged in a row. The print head 22 generates heat corresponding to the print data supplied to the print head 22 in the heating element array in accordance with the stop timing of the ink ribbon 14 and the print-receiving tape 12 that are intermittently fed by the print head drive circuit 37. The element is driven to transfer the ink on the ink ribbon 14 to the printing tape 12. As a result, the print head 22 operates as a head that prints line by line on the print-receiving tape 12 (medium) by driving the print head drive circuit 37 based on the print data generated by the control unit 30.

The printing apparatus 1 includes a print head 22 (see FIG. 3), a print head drive circuit 37 that drives the print head 22, a stepping motor 38, and a stepping motor 38. A motor drive circuit 39 for driving the tape, a tape cut motor 40, a cut motor drive circuit 41 for driving the tape cut motor 40, and a tape width detection switch 29. The printing apparatus 1 includes a display unit 4 (see FIG. 1), a display unit drive circuit 35 that drives the display unit 4, and a keyboard input unit 3 (see FIG. 1). Furthermore, the printing apparatus 1 includes a control unit 30, a ROM 32, and a RAM 33.

  The display unit drive circuit 35 displays information related to input from the keyboard input unit 3, selection menus for various settings, messages related to various processes, and the like, based on instructions based on display control data generated by the control unit 30. Part 4 is displayed.

  The stepping motor 38 rotationally drives the platen roller 23 and the ink ribbon winding drive shaft 25 described above with reference to FIG. The stepping motor 38 operates as a drive motor that conveys the printing tape 12 along a certain direction by rotating in one direction as printing data is printed on the printing tape 12 (medium). Further, as will be described later, the stepping motor 38 rotates in a direction opposite to the one direction which is the direction of rotation before interruption during interruption of printing of print data on the print-receiving tape 12 as necessary. Can also be performed. The stepping motor 38 is controlled via the motor drive circuit 39 in accordance with an instruction based on the print control data generated by the control unit 30.

  The tape cut motor 40 is a common motor that drives the full cut mechanism 27 and the half cut mechanism 28 described above with reference to FIG. 3, and is engaged with one of the full cut mechanism 27 and the half cut mechanism 28. It is provided so as to be separable from the other, and drives a selected cutting mechanism among the full-cut mechanism 27 and the half-cut mechanism 28. The tape cut motor 40 is controlled via the cut motor drive circuit 41 in accordance with an instruction based on the print control data generated by the control unit 30.

  In the ROM 32, a system program, pattern data such as various characters defined by the JIS code, an input data processing program, a display program, a printing program, and the like are registered in advance. Note that these programs are read and stored from a storage medium such as a memory card inserted into a storage medium insertion slot (not shown) of the printing apparatus 1 or an external device such as a personal computer connected to an external device connection terminal. Good.

  The control unit 30 is a microprocessor, for example, and activates a system program or the like stored in the ROM 33 in response to a key input by the user from the keyboard input unit 3, and uses the RAM 32 as a work memory to input to the keyboard input unit 3. A key input by the user and a tape width detection signal from the tape width detection switch 29 are received. The control unit 30 operates as a print data generation unit that generates print data to be printed on the printing tape 12 (medium). In addition, the control unit 30 print control data for controlling the print head 22, the stepping motor 38, and the tape cut motor 40 via the print head drive circuit 37, the motor drive circuit 39, and the cut motor drive circuit 41, respectively. It operates as a print control data generation unit that generates. Further, the control unit 30 operates as a display control unit that controls the display unit 4 via the display unit driving circuit 35. Furthermore, the control unit 30 operates as a reverse rotation control unit for controlling the stepping motor 38 via the motor drive circuit 39.

  The RAM 32 temporarily stores input data, display data, print data, print control data, pattern data such as characters read from the ROM 32 by the control unit 30, display data, print data, and the like from the keyboard input unit 3 and the touch panel 7. Remember.

  Next, the printing process of the printing apparatus 1 will be described.

In the printing apparatus 1, printing may be interrupted in order to perform a predetermined process during printing. For example, as described above with reference to FIG. 3, when the printing tape 12 is cut together with the release tape by the full cut mechanism 27, only the printing tape 12 is cut by the half cut mechanism 28 and the peeling tape is not cut. . Alternatively, there are cases where the temperature of the thermal head rises too much during printing and the thermal head needs to be cooled in order to perform appropriate printing control, or when print data expansion processing is performed during printing. The predetermined process is not limited to these examples, and may be another process as long as it is necessary to interrupt printing in order to perform the predetermined process. When the printing is interrupted, in order to prevent the printing tape 12 from being displaced during a predetermined process, the control unit 30 in FIG.
In a state where the print head is held at the printing position (see FIG. 3), the drive of the print head 22 by the print head drive circuit 37 and the rotational drive of the platen roller 23 by the stepping motor 38 are stopped. When the predetermined processing is completed, the control unit 30 controls the print head drive circuit 37 and the motor drive circuit 39 to resume printing.

  Here, when printing is interrupted, for example, as shown in FIG. Therefore, in each of the embodiments described below, by performing reverse processing of the print-receiving tape 12 based on print data at the time of printing interruption control, for example, as shown in FIG. Printing that does not occur is possible. Note that one of the reasons why printing omission occurs is that the print-receiving tape 12 is sent during the above-described print interruption control, but various other factors are entangled to cause printing omission. It is done.

  FIG. 6 is a flowchart illustrating the first embodiment of the printing process executed by the control unit 30 of FIG. This process is an operation in which the control unit 30 executes a print processing program stored in the ROM 32. In the following description, FIGS. 1 to 4 will be referred to as appropriate.

  First, when a user operates the keyboard input unit 3, data to be printed is input, a format such as a character size and a margin length is set, and a print key is operated. As a result, pattern data corresponding to the character data input from the keyboard input unit 3 is read from the ROM 32 and developed in the print data area of the RAM 33. Here, in this specification, the character data includes pure character data, but is not limited to this, and various characters and symbols other than characters and various designs that can be printed on a medium using the printing apparatus of the present invention. May include various types of data. Note that when the amount of print data to be expanded is large, all the data designated for printing cannot be expanded in the RAM 33 at a time. At that time, the control unit 30 develops and prints the print data in a plurality of times while appropriately interrupting the printing.

  Subsequently, the control unit 30 drives the stepping motor 38 to rotate forward via the motor drive circuit 39. As a result, the platen roller 23 is moved to a printing position where the platen roller 23 is pressed against the print head 22.

  Thereafter, the control unit 30 starts executing the printing process exemplified by the flowchart of FIG.

  First, the control unit 30 reads print data for one line from the print data area of the RAM 33 (step S601). The print data for one line designates which heating element of the predetermined number of dot-like heating elements of the print head 22 is energized for printing.

  Next, based on the print data for one line read out in step S601, the control unit 30 uses the print head drive circuit 37 to output the corresponding one line of the predetermined number of dot-like heating elements of the print head 22. One or more heating elements determined by the print data are energized, and printing for one line is executed (step S602).

  Next, the control unit 30 determines whether or not to stop the printing operation by the predetermined processing described above (step S603).

  If it is determined that the printing operation is not stopped (No in step S603), the control unit 30 outputs a motor pulse signal for normal rotation driving to the stepping motor 38 via the motor driving circuit 39. Then, the printing tape 12 is conveyed to the normal rotation method (step S604).

  Thereafter, the control unit 30 designates the next line (step S605).

  The control unit 30 determines whether or not the print end position has been reached as a result of the designation of the next line in step S605 (step S606).

  If it is determined that the print end position has not been reached (No in step S606), the control unit 30 returns to the process in step S601 and executes the print process for the next line.

If it is determined that the printing operation is to be stopped (Yes in step S603), the control unit 30 first determines whether to perform the reverse driving of the stepping motor 38 based on the print data or the print control data. (Step S607 ).

Control unit 30, the result of the determination in step S607 is, when was the determination not to implement the reverse drive (when the determination of step S608 is No), the process proceeds to step S 610 to be described later.

On the other hand, when the result of the determination in step S607 is that the reverse rotation drive is to be performed (when the determination in step S608 is Yes), the control unit 30 passes the stepping motor 38 via the motor drive circuit 39. Are driven in reverse by a uniform number of steps X1 based on the print control data (step S609) .

  Subsequently, the control unit 30 operates the full cut mechanism 27 or the half cut mechanism 28 (see FIG. 3) by driving the tape cut motor 40 based on the print control data via the cut motor drive circuit 41. Then, the cutting process of the tape 12 to be printed by the full cut or the half cut described above with reference to FIG. 3 is executed (step S610).

  Thereafter, the control unit 30 returns to the process of step S601 and executes a one-line printing process.

  If it is determined that the printing end position has been reached (Yes in step S606), the control unit 30 ends the flowchart of FIG. 6 and ends the printing process.

In the printing process according to the first embodiment described above, the reverse driving of the stepping motor 38 is performed based on the print data when printing is stopped. In this case, if the reverse rotation operation is always performed by a uniform amount when printing is stopped, there is a possibility that printing omission may occur. Specifically, for example, as shown in FIG. 5A, the number of dots a in the character data portion in the line L1 which is a line immediately before the stop of printing is large, and is the next line of the line L1 and immediately after resuming printing. When the number of dots b in the character data portion in the line L2, which is the first line, is small (hereinafter referred to as the first condition for simplicity), the number of dots a is small to some extent or the number of dots b is large to some extent. If the reverse rotation operation is performed by the same amount as in the case (hereinafter referred to as the second condition for the sake of simplicity), there is a possibility that printing omission may occur. On the contrary, when the second condition is satisfied, it has been found that the omission of printing can be suppressed by performing the reverse driving operation by a uniform amount. That is, when the print data before and after the printing is interrupted satisfies the first condition, the reverse operation of the stepping motor is not performed and the first condition is not satisfied (that is, the above-described first condition is satisfied). In the case where the second condition is satisfied), the stepping motor is reversely operated by a uniform amount, thereby suppressing the occurrence of printing omission when either the first condition or the second condition is satisfied. Can do. In addition, in order to energize the heating element corresponding to the dot designated by the print data of each of the lines L1 and L2 among the plurality of heating elements of the head, energization is performed based on the number of print data dots and the print data. The number of heating elements is equal. As described above, the control unit 30 determines whether or not the stepping motor 38 is rotated while the operation of the stepping motor 38 is interrupted in the direction opposite to that before the operation of the stepping motor 38 is interrupted. It operates as a reverse rotation control unit determined based on In the above example, the reverse operation of the stepping motor is controlled based on the print data before and after the printing is interrupted. However, the reverse driving of the stepping motor is performed based on the printing interruption time, the temperature of the print head 22 which is a thermal head, and the like. May be controlled. For example, as described above, when the temperature change of the head is sufficiently small during the interruption, that is, when the head temperature is maintained within a certain range during the interruption of printing because the interruption time of printing is relatively short, When the head temperature is maintained within a certain range during printing interruption by appropriately energizing during printing interruption, the adhesion phenomenon between the print head 22 and the ink ribbon 14 (see FIGS. 2 and 3). The occurrence of printing failure can be suppressed, and printing omission can be suppressed by performing the reverse drive operation by a uniform amount. That is, the control unit determines that the head temperature is held within a certain range during the printing interruption based on the printing interruption time at this time and the printing control data for performing the energization control during the printing interruption. In some cases, a reverse rotation operation is performed by a uniform amount, but conversely, the head temperature is not held within a certain range during printing interruption based on printing control data such as printing interruption time or energization control. When the control unit determines that the reverse drive is not performed. In this way, the control unit 30 determines whether or not to rotate the stepping motor 38 in the direction opposite to that before the operation of the stepping motor 38 is interrupted, while the operation of the stepping motor 38 is interrupted. It operates as a reverse rotation control unit that is determined based on the state. As a result, it is possible to effectively suppress the occurrence of print omission. Therefore, in this embodiment, in which the control unit 30 executes the determination process based on the above print data or print control data in step S607, S608, according to the determination result, to implement the reverse rotation in the step S609 is there.

  In this way, in the first embodiment, when printing is stopped, it is determined whether to perform reverse driving according to the status of the print data or print control data, and is determined in advance when reverse driving is necessary. By performing reverse rotation by the constant amount X1, which is a constant, and by not performing this reverse rotation when not required, printing omission occurs regardless of the status of the print data or print control data. This can be suppressed.

  FIG. 7 is a flowchart illustrating a second embodiment of the printing process executed by the control unit 30 of FIG. This process is an operation in which the control unit 30 executes the print processing program stored in the ROM 32 as in the case of FIG. 6 according to the first embodiment.

The flowchart of FIG. 7 is different from the flowchart of FIG. 6 as follows. In the flowchart of FIG. 6 according to the first embodiment, when printing is stopped (when the determination in step S603 is Yes), the reverse rotation drive processing (step S609) of the stepping motor 38 is executed after the determination processing in steps S607 and S608. Then, the cutting process (step S610) of the tape 12 to be printed is executed. On the other hand, in the flowchart of FIG. 7 according to the second embodiment, the printing tape 12 is cut (step S610) after the determination process of step S607 when printing is stopped (when the determination of step S603 is Yes). ) Is executed, and thereafter, reverse drive processing (step S609) of the stepping motor 38 is executed according to the determination results of steps S607 and S608 . The other processes in FIG. 7 are the same as those in FIG.

  Also in the printing process of the second embodiment described above, as in the case of the first embodiment, when printing is stopped, it is determined whether to perform reverse driving according to the status of the print data or the print control data. When the reverse drive is required, the reverse drive is performed by the above-mentioned uniform amount X1, which is a predetermined constant. When the reverse drive is not required, the reverse drive is not performed. Alternatively, it is possible to suppress the occurrence of print loss regardless of the status of the print control data.

  FIG. 8 is a flowchart illustrating the third embodiment of the printing process executed by the control unit 30 of FIG. This process is an operation in which the control unit 30 executes the print processing program stored in the ROM 32 as in the case of FIG. 6 according to the first embodiment.

The flowchart in FIG. 8 differs from the flowchart in FIG. 6 in that the determination processing in S607 and S608 in the flowchart in FIG. 6 executed when printing is stopped (when the determination in step S603 is Yes) and the reverse driving of the stepping motor 38 are performed. In the flowchart of FIG. 8, the process (step S <b> 609) is a process in which the reverse rotation number x is a variable, the reverse rotation number x is specifically calculated (step S <b> 801), and the stepping motor 38 is driven in reverse rotation by the reverse rotation number x. This is executed as (Step S802). Other processes in FIG. 8 are the same as those in FIG.

  FIG. 9 is a flowchart illustrating a detailed example of the calculation process of the reverse rotation number x in step S801 in FIG.

  In the flowchart of FIG. 9, the control unit 30 firstly displays the dot number a (see FIG. 5A) of the current line L1 corresponding to the print stop position on the print data for one line read in step S601 of FIG. (See) is counted (step S901). Here, the print data for one line indicates which heat generating element is energized in order to perform printing of one line corresponding to the print data for one line among the plurality of heat generating elements of the print head 22. In this print data, the number of dots is the number of heating elements designated to be energized in order to print one line corresponding to the print data for one line. is there.

Next, the control unit 30 reads the print data for the next line of the print data for one line read in step S601 in FIG. 8, and the current position of the print stop position on the print data for that line. The number of dots b (see FIG. 5A) of the line L2 next to the line L1 is counted (step S902).

  Then, the control unit 30 determines that the dot a calculated in step S901 is larger than the specified number A (first number) and the dot b calculated in step S902 is smaller than the specified number A (second number). It is determined whether or not it is smaller than the number (step S903). As described in steps S901, S902, and S903, the control unit 30 causes the stepping motor 38 to be suspended in the direction opposite to that before the operation of the stepping motor 38 is interrupted. Reverse rotation control that determines whether to rotate the first step by a first amount or to rotate a second amount smaller than the first amount while the operation of the stepping motor 38 is interrupted based on the state of the print data Operates as a part.

  If the determination in step S903 is No, the control unit 30 sets the step number x for driving the stepping motor 38 in the reverse direction to the prescribed step number X1 (step S904).

  When the determination in step S903 is No, the control unit 30 subtracts the number of steps x for driving the stepping motor 38 in the reverse direction by subtracting the other specified number of steps X2 from the specified number of steps X1 “X1−X2”. (Step S905). Here, X2 is set to an appropriate number equal to or less than X1. For example, when X2 = X1 is set, the reverse drive step number x set in step S905 is 0 (zero). That is, in this case, reverse rotation driving is not performed. Of course, X2 may be an appropriate number not greater than X1 but less than X1. In this case, the reverse drive step number x is controlled according to the print data pattern.

  After the process of step S904 or S905, the control unit 30 ends the reverse rotation number x calculation process of step S801 of FIG.

  Returning to the description of the flowchart of FIG. 8, the control unit 30 controls the motor drive circuit 39 after the process of step S <b> 801 to drive the stepping motor 38 by the reverse drive step number x calculated in step S <b> 801. (Step S802).

  And the control part 30 performs the tape cutting process similar to the case of FIG. 6 (step S610), and returns to the process of step S601 after that.

  In the printing process according to the third embodiment described above, when printing is stopped, in step S903 in FIG. 9, the number of print dots a of the line L1 when printing is stopped and the line L2 when printing is resumed (the line next to the line L1). ) Is less than the specified value “A−B”, the stepping motor 38 is driven reversely by the specified value X1, and when the difference is larger than the specified value “A−B”, The reverse drive step number x is set to a value “X1−X2” which is smaller than the prescribed value X1, for example, 0 (no reverse drive).

  In this way, in the third embodiment, when printing is stopped, it is determined whether to perform reverse rotation driving according to the status of print data, and when reverse rotation driving is necessary, a variable that is specifically calculated is used. By performing reverse drive for a certain amount x and not performing this reverse drive when unnecessary, it is possible to effectively suppress the occurrence of print loss regardless of the status of the print data. Become.

  In the third embodiment, the reverse drive amount x is changed according to the status of print data. However, the present invention is not limited to this, and is the same as in the first and second embodiments described above. The amount x of reverse driving may be changed according to the status of the print control data. FIG. 10 is a flowchart showing a detailed example of processing for changing the amount x of reverse rotation driving by comprehensively judging print data and print control data.

  First, the control unit 30 determines whether to perform reverse driving of the stepping motor 38 based on the print data or the print control data (steps S1001 and S1002).

  As a result, in step S1001, the control unit 30 holds the head temperature within a certain range during printing interruption based on, for example, printing interruption time or printing control data for performing energization control during printing interruption. If it is determined that the reverse drive is performed in step S1002, the reverse drive operation is performed by a uniform amount, that is, x = X1 (step S905).

  Conversely, in step S1001, the control unit 30 determines that the head temperature is not held within a certain range during printing interruption based on printing control data such as printing interruption time and energization control, for example, step S1002. If it is determined that the reverse drive is not performed in step S2, the reverse drive operation is not performed, that is, x = 0 is set (step S904).

  In the modification of the third embodiment, whether to perform reverse driving is determined according to the status of the print control data, and when reverse driving is necessary, the amount x, which is a specifically calculated variable, is determined. By performing reverse rotation driving for the same amount and not performing reverse rotation driving when unnecessary, it is possible to effectively suppress the occurrence of print loss regardless of the status of the print control data. As described above, in the modification of the third embodiment, the control unit 30 causes the stepping motor 38 to be suspended in the direction opposite to that before the operation of the stepping motor 38 is interrupted. The reverse rotation is determined based on the state of the print control data to determine whether to rotate the first step by a first amount or to rotate the stepping motor 38 by a second amount smaller than the first amount while the operation of the stepping motor 38 is interrupted. Operates as a control unit.

  FIG. 11 is a flowchart illustrating a fourth embodiment of the printing process executed by the control unit 30 of FIG. This process is an operation in which the control unit 30 executes the print processing program stored in the ROM 32, as in the case of FIG. 8 according to the third embodiment.

  The flowchart of FIG. 11 is different from the flowchart of FIG. 8 as follows. In the flowchart of FIG. 8 according to the third embodiment, when printing is stopped (when the determination in step S603 is Yes), the reverse rotation number x calculation process (step S801) is executed, and then the stepping motor 38 is driven in reverse rotation. The process (step S802) is executed, and further the cutting process of the printing tape 12 (step S610) is executed. On the other hand, in the flowchart of FIG. 11 according to the fourth embodiment, when printing is stopped (when the determination in step S603 is Yes), the cutting process (step S610) of the print-receiving tape 12 is performed after step S801. After the execution, a reverse drive process (step S802) of the stepping motor 38 is executed. Other processes in FIG. 11 are the same as those in FIG.

  Even in the printing process of the fourth embodiment described above, in the same manner as in the case of the third embodiment, in step S801 in FIG. 11, printing is stopped by a modification of the inversion number x calculation process illustrated in FIG. Sometimes, it is determined whether to perform reverse driving according to the status of the print data. When reverse driving is required, reverse driving is performed by the amount x that is specifically calculated. By not performing this reverse rotation drive, it is possible to effectively suppress the occurrence of print loss regardless of the print data status.

  In the fourth embodiment described above, the reverse drive amount x is changed according to the status of the print data. However, the present invention is not limited to this, and the above-described first embodiment, second embodiment, and Similarly to the modification of the third embodiment, the reverse drive amount x may be changed according to the status of the print control data. Also in the modification of the fourth embodiment, it is determined whether to perform reverse rotation driving according to the state of the print control data, and when the reverse rotation driving is necessary, an amount x that is a specifically calculated variable is set. By performing reverse rotation driving for the same amount and not performing reverse rotation driving when unnecessary, it is possible to effectively suppress the occurrence of print loss regardless of the status of the print control data.

  In each above-mentioned embodiment, although the to-be-printed tape 12 was the various tapes by which the surface opposite to a printing surface was made into the adhesion surface and the peeling tape was affixed on the adhesion surface, it is not restricted to this, but to-be-printed Even when the tape 12 is a case in which a release tape is not attached to the adhesive surface and the adhesive surface is exposed, printing omission occurs regardless of the pattern of the print data, as in each embodiment. This can be effectively suppressed.

  A comparative experiment was performed according to the embodiment described above, and the effect of the present invention was confirmed. The contents and results will be described below. In any of the examples and the comparative examples, the printing control is such that the process of temporarily interrupting the printing in order to cut the tape completely is interrupted at least once between the start and the end of the printing of each label. Printing was performed based on the data.

Example 1
Using a tape printer testing machine, print data satisfying the first condition was printed on a 46 mm wide tape. The printing control data is such that the process of interrupting printing is interrupted only once between the start and end of printing of each label. In addition, while the printing was interrupted, the state where the stepping motor was stopped was maintained, and then the printing was resumed.

(Example 2)
Using a tape printer tester, print data satisfying the second condition was printed on a 46 mm wide tape. The printing control data is such that the process of interrupting printing is interrupted only once between the start and end of printing of each label. Further, during the interruption of printing, the stepping motor was rotated in the direction opposite to that before the interruption, and then the printing was resumed.

(Example 3 and Example 4)
Using a tape printer testing machine, print data satisfying the second condition described above was printed on a 12 mm wide tape as Example 3 and a 9 mm wide tape as Example 4. The printing control data is such that the process of interrupting printing is interrupted twice between the printing start and end of each label. Further, during the interruption of printing, the stepping motor was rotated in the direction opposite to that before the interruption, and then the printing was resumed.

(Comparative Example 1)
Using a tape printer testing machine, print data satisfying the first condition was printed on a 46 mm wide tape. The printing control data is such that the process of interrupting printing is interrupted only once between the start and end of printing of each label. Further, during the interruption of printing, the stepping motor was rotated in the direction opposite to that before the interruption, and then the printing was resumed.

(Comparative Example 2)
Using a tape printer tester, print data satisfying the second condition was printed on a 46 mm wide tape. The printing control data is such that the process of interrupting printing is interrupted only once between the start and end of printing of each label. Further, the state in which the stepping motor was stopped was maintained, and then printing was resumed.

(Comparative Example 3 and Comparative Example 4)
Using a tape printer testing machine, print data satisfying the second condition described above was printed on a 12 mm wide tape as Comparative Example 3 and a 9 mm wide tape as Comparative Example 4. The printing control data is such that the process of interrupting printing is interrupted twice between the printing start and end of each label. In addition, while the printing was interrupted, the state where the stepping motor was stopped was maintained, and then the printing was resumed.

(Experimental result)
12A shows the printing result of Example 1 (tape width: 46 mm), FIG. 12B shows the printing result of Example 2 (tape width: 46 mm), and FIG. 12C shows the printing result of Example 3 (tape width). : 12 mm), FIG. 12 (d) shows the printing result of Example 4 (tape width: 9 mm), FIG. 13 (a) shows the printing result of Comparative Example 1 (tape width: 46 mm), and FIG. 13 (b). Is the printing result of Comparative Example 2 (tape width: 46 mm), FIG. 13C is the printing result of Comparative Example 3 (tape width: 12 mm), and FIG. 13D is the printing result of Comparative Example 4 (tape width: 9 mm). It is a figure which shows a result, respectively.

  First, when printing data satisfying the first condition was printed on a 46 mm wide tape, in Example 1, it was confirmed that a part of the printing was missing as shown in FIG. Compared to 1, it was less frequent and smaller in size. On the other hand, when the state where the stepping motor is stopped is maintained, the stepping motor is reversed in the opposite direction. In Comparative Example 1, as shown in FIG. It was found to occur at a frequency. Therefore, when printing print data that satisfies the first condition on a 46 mm wide tape, it is better to keep the stepping motor stopped during printing interruption than to rotate the stepping motor in the opposite direction. In other words, it can be said that the state of missing printing has been improved.

  When printing data satisfying the second condition is printed on a 46 mm wide tape, in Example 2 and Comparative Example 2, as shown in FIG. 12B and FIG. I was able to print. Therefore, when printing the print data satisfying the second condition on a 46 mm wide tape, the printing result is generally good regardless of whether or not the stepping motor is rotated in the reverse direction during the printing interruption. I can say that.

  Summarizing the results of Example 1, Example 2, Comparative Example 1 and Comparative Example 2 described above, when the print data to be printed satisfies the first condition, the state in which the stepping motor is stopped during the interruption of printing is maintained. Then, when the stepping motor is rotated in the reverse direction, the missing print state is improved, and when the print data to be printed satisfies the second condition, the printing is performed in the same manner as when the stepping motor is rotated in the reverse direction. The results were found to be generally good. Therefore, when at least the print data to be printed satisfies the first condition, the state in which the stepping motor is stopped during the interruption of printing is maintained, which is better than when the stepping motor is rotated in the opposite direction. It can be said that a good printing result was obtained.

  Next, when print data satisfying the second condition is printed on each of the 46 mm width, 12 mm width, and 9 mm width tapes, in Example 2, Example 3, and Example 4, FIGS. As shown in (d), the printing results were generally good. On the other hand, in Comparative Example 2, Comparative Example 3, and Comparative Example 4, the printing results were as shown in FIGS. 13B, 13C, and 13D, respectively. That is, in Comparative Example 2, the printing result was generally good, but in Comparative Example 3 and Comparative Example 4, printing omission occurred. Specifically, in the case of 12 mm which is the comparative example 3, “U” (half cut) and “i” (second full cut) after the second sheet, and in the case of 9 mm which is the comparative example 4 “e” Printing failure occurred between “O” and between “I” and “U” on the second and subsequent sheets.

  Therefore, when the print data to be printed satisfies the second condition, the stepping motor is rotated in the opposite direction by holding the state where the stepping motor is stopped during the interruption of printing regardless of the tape width. It was found that it is possible to avoid the printing result from becoming poor as compared with. In printing on at least a plurality of tapes having different tape widths, when printing the print data that satisfies the second condition, if the stepping motor is rotated in the reverse direction while printing is interrupted, the stepping motor is stopped. It can be said that the state of printing omission is improved as compared with holding the.

  From the above experimental results, when at least the print data to be printed satisfies the first condition, it is better to hold the state where the stepping motor is stopped during printing interruption than to rotate the stepping motor in the opposite direction. It has been found that the state of missing print is improved. Also, when the print data to be printed satisfies the second condition, when the stepping motor is rotated in the reverse direction while printing is interrupted, the state in which the stepping motor is stopped is maintained rather than holding the stopped state. It has been found that there is a case where it is improved.
