Description

  The present invention relates to a printing apparatus capable of executing borderless printing at least in the longitudinal direction of a long sheet, and a control method for the printing apparatus.

  2. Description of the Related Art Conventionally, this type of printing apparatus generally performs printing by protruding from a desired printing area of paper, and then cuts the protruding portion from the desired printing area by a subsequent cutting process (see, for example, Patent Document 1). In this type of cutting process, the printing apparatus described in Patent Document 1 first cuts a boundary between a protruding portion printed at the rear end in the longitudinal direction of a sheet and a desired printing area. In this cutting process, the printing apparatus obtains the protruding amount of the trailing edge from the paper size and the image size to be printed, and determines the cutting position in consideration of the protruding amount. Note that the printing apparatus realizes borderless printing by printing the front end outside the paper.

JP 2003-341161 A

  In the above-described printing apparatus, in order to determine the cutting position in the post-cut process, the amount of protrusion of the protruding portion is obtained from the paper size and the image size to be printed. The amount of protrusion is considered to be the length of the protruding portion in the direction orthogonal to the cutting direction. However, the above printing device calculates the length of the protruding portion each time borderless printing is performed. This complicates the processing of the printing apparatus. Even if the length of the protruding portion is calculated, if the cutting position is the rear end of the protruding portion, there is a possibility that the protruding portion slightly remains on the paper in the apparatus. Also, borderless printing at the front edge of the paper requires a reverse conveyance of the paper when the printing starts from a state where the front edge has already passed through the print head, and the conveyance operation becomes complicated.

  SUMMARY OF THE INVENTION In view of the above, the present invention provides a printing apparatus and a printing apparatus control method capable of performing printing and paper cutting without leaving any protruding portion by simple processing in borderless printing in the paper longitudinal direction. It is an issue to provide.

  The printing apparatus of the present invention is a printing apparatus capable of executing borderless printing on a long sheet in at least the sheet longitudinal direction, and includes a printing unit that prints a print area based on print data, and a sheet. A cut section that cuts in the width direction, and a print / cut control section that controls the print section and the cut section. The print / cut control section starts from the front edge of the print area in the longitudinal direction of the paper when performing borderless printing. A pre-cut process for cutting the inside of the printing area by a predetermined length, a main cutting process for cutting the inside of the printing area by a predetermined length from the rear edge in the paper longitudinal direction of the printing area, and a rear of the printing area in the paper longitudinal direction Printing is performed by providing a blank area on the outside adjacent to the edge, and a post-cutting step of cutting the trailing edge of the blank area is performed.

  A method for controlling a printing apparatus according to the present invention includes a printing unit that prints a print region based on print data on a long sheet, and a cutting unit that cuts the sheet in the width direction. In the control method, the cutting section cuts the inside of the printing area by a predetermined length from the front edge in the paper longitudinal direction of the printing area, and the cutting section starts from the rear edge of the printing area in the paper longitudinal direction. The main cutting step of cutting the inside of the printing area by a predetermined length, and the printing unit performs printing by providing a blank area on the outside adjacent to the rear end in the paper longitudinal direction of the printing area. And a post-cutting step of cutting a rear end of the blank area.

  According to these configurations, since each cut position is determined based on the distance from each end of the print area, the cut position can be determined by a simple processing method. Further, since the inside of the printing area is cut in the front cutting step and the main cutting step, borderless printing can be reliably performed at the front end and the rear end of the paper. Further, in the post-cutting step, a blank area is provided from the rear end of the print area and the rear end of the blank area is cut, so that the outside of the print area can be reliably cut. That is, it is possible to cut the paper without reliably leaving a protruding portion of printing.

  In this case, it is preferable to perform printing by providing a blank area outside the print area in the longitudinal direction of the paper adjacent to the front edge in the longitudinal direction.

  According to this configuration, it is possible to surely print on the paper from the front end of the printing area, so that the inside of the apparatus is not soiled by printing outside the paper.

  In this case, it is preferable to further include a mode switching unit for switching the mode to either the first mode in which the post-cut process is executed or the second mode in which the post-cut process is not executed.

  According to this configuration, it is possible to select whether or not to execute the post-cutting process for generating an unnecessary portion of the printed paper according to the user's preference.

  In this case, when the normal printing for cutting at least the trailing edge of the printing area can be executed and the mode is the second mode, the printing / cutting control unit performs the normal printing in the longitudinal direction of the printing area. It is preferable to perform a precut process in which printing is performed by providing a blank area on the outside adjacent to the front edge, and the rear edge of the blank area is cut.

  According to this configuration, by performing the precut process, when the protruding portion is generated by the previous printing, the protruding portion can be separated.

  In this case, the cutting unit includes a half-cut unit that cuts a printed portion of the paper so as to be manually separable, and a full-cut unit that fully cuts the paper, and the printing / cut control unit performs the main cutting process or / In addition, it is preferable to execute full cut in the post-cut process and perform half cut in a process other than the process in which the full cut is performed.

  According to this configuration, since the printed portion can be cut in a state of being continuous with the paper by half-cutting, the length of the blank area affected by the distance between the cut portion and, for example, the discharge port of the apparatus is shortened. Can do. Therefore, the unnecessary part of the printed paper can be reduced as a whole.

Then, the drive control of the print head 7, the cutter motor 25, and the tape feed motor 26 is performed in accordance with the print instruction.

  Here, with reference to FIG. 3 to FIG. 5, the normal printing and the borderless printing of this embodiment will be described in detail. FIG. 3 is a diagram schematically showing a print area, a cut position, and a label to be created when normal printing and borderless printing are executed in the first mode.

  As shown in FIG. 3A, when normal printing is executed in the first mode, a label margin C based on the above margin setting is provided outside the front end and the rear end of the label image P, and the label image P The printing area A is set from the two label margins C. The cut position is set to the rear end position of the printing area A. The tape printer 1 performs printing based on the print data and cuts the rear end of the print area A (normal printing / cutting process). As shown in the figure, a label having a margin is created by the main printing, and a blank tape T is left in the tape printer 1.

  As shown in FIG. 3B, when borderless printing is executed in the first mode, the margin setting is set to “margin: 0 mm” as described above, so that the label image P is printed in the print area. A. Further, margin areas B are provided outside the front end and the rear end of the print area A, respectively. The length of the blank area B is a length exceeding the distance from the tape cutter 23 to the discharge port 22 of the apparatus. This is to prevent the discharged label pieces from remaining in the apparatus. The cutting positions are set at three positions: a position that is a predetermined length from the front end and the rear end of the printing area A, and a rear end position of the blank area B that is provided outside the rear end of the printing area A. The The tape printer 1 performs printing by providing a blank area B outside the front end of the print area A, and cuts a position a predetermined length from the front end of the print area A (pre-cut process). Then, printing proceeds based on the print data, and a position inside by a predetermined length from the rear end of the printing area A (in this embodiment, 3 mm inside, but this predetermined length is arbitrary) is cut. (This cut process). Then, a margin area B is provided outside the rear end of the print area A, and the rear end of the margin area B is cut (post-cut process). As shown in the drawing, a borderless label having no margin (border) is created by the main printing, and the two label pieces on which a part of the printing area A is printed are discharged out of the apparatus. On the other hand, a blank tape T is left in the tape printer 1.

  On the other hand, FIG. 4 is a diagram schematically showing a print area, a cut position, and a label to be created when normal printing and borderless printing are executed in the second mode. The figure shows a case where each printing is executed after normal printing is executed in the same mode.

  As shown in FIG. 4A, when normal printing is executed after normal printing is executed in the second mode, a label margin C based on the above margin setting is provided outside the front and rear ends of the label image P. And a print area A is set from the label image P and the two label margins C. Further, a blank area B is provided outside the front end of the print area A. The cut positions are set at two positions, that is, the boundary position between the margin area B and the print area A and the rear end position of the print area A. The tape printer 1 performs printing by providing a blank area B outside the front end of the print area A, and cuts the boundary position between the blank area B and the print area A (pre-cut process). Then, printing is advanced based on the print data, and the trailing edge of the printing area A is cut (normal printing / cutting process). As shown in the figure, a label having a margin is created by the main printing, and a blank label piece is discharged out of the apparatus. On the other hand, a blank tape T is left in the tape printer 1.

  As shown in FIG. 4B, when borderless printing is executed after normal printing is executed in the second mode, the margin setting is set to “margin: 0 mm” as described above. The label image P becomes the printing area A. Further, a blank area B is provided outside the front end of the print area A. Then, the cutting positions are set at two locations that are a predetermined length inside from the front end and the rear end of the printing area A. The tape printer 1 performs printing by providing a blank area B outside the front end of the print area A, and cuts a position a predetermined length from the front end of the print area A (pre-cut process). Then, printing is performed based on the print data, and a position inside by a predetermined length from the rear end of the printing area A is cut (main cutting step). As shown in the drawing, a borderless label having no margin is created by the main printing, and a label piece on which a part of the printing area A is printed is discharged out of the apparatus. On the other hand, in the tape printer 1, the tape T on which a part of the printing area A is printed is left at the front end.

  FIG. 5 shows a case where each printing is executed after borderless printing is executed in the same mode. The print area to be set, the cut position, and the label to be created are the same as those shown in FIG. 4, but a part of the print area A set at the front end of the tape T in the borderless printing previously executed is Since printing is performed, the pre-cut process in normal printing can be performed to separate the protruding portion from the previous printing from the label to be created. In this mode, when performing borderless printing, the post-cut process in borderless printing in the first mode is not executed, and therefore, when continuous borderless printing is performed, the discharge of unnecessary label pieces is suppressed. Can do. That is, the label pieces between the labels can be shared.

  Next, the printing process of the tape printer 1 will be described with reference to the flowchart of FIG. When the tape printer 1 receives the [print] key press signal (S01), the mode is the first mode (S02: first mode), and the margin setting is not “margin: 0 mm”. If this is the case (S03: No (normal printing)), the normal printing / cutting step is executed (S04). On the other hand, if “margin: 0 mm” (S03: Yes (borderless printing)), the pre-cut process (S05), the main cut process (S06), and the post-cut process (S07) are executed.

  On the other hand, when the mode is the second mode (S02: second mode) and the margin setting is not “margin: 0 mm” (S08: No (normal printing)), after executing the precut process (S09) A normal printing / cutting process is executed (S10). On the other hand, if it is “margin: 0 mm” (S08: Yes (borderless printing)), the previous cutting step (S11) and the main cutting step (S12) are executed.

  According to the tape printer 1 described above, in borderless printing, the cutting position in the post-cutting process is determined based on the distance from the printing area A, so that the cutting position can be determined by a simple method. . Further, since the rear end of the blank area B provided outside the rear end of the print area A is cut, the rear cut can be surely executed outside the print area A. In addition, since the second mode can suppress the discharge of the label pieces that become dust, the consumption of the tape T can be saved.

  The cutting of the tape T executed at the cutting position set in each printing may be a half cut or a full cut. In this case, the cut that cuts between the labels (the cut in the normal printing / cutting process, the cutting in the main cutting process and / or the post-cutting process) is preferably a full cut. In addition, since the label piece that becomes dust is attached to the mount (peeling tape Tb) by cutting the half-cut, the label piece is not left in the apparatus independently. The piece can be as short as possible. Therefore, consumption of the tape T can be saved. The cutting performed in the half cut may be a perforation cut.

  Further, in borderless printing, a dot discrimination target area is provided in a portion including each cut position from the front end and the rear end of the print area A, and the presence or absence of a print dot in the dot discrimination target area is determined from the print data. Only when it is determined as “present”, the pre-cut process and / or the post-cut process may be executed. According to this, an unnecessary pre-cut process and / or post-cut process is performed to remove an unnecessary label piece even though no print dot actually exists in the vicinity of the front end and the rear end of the print area A. It can be prevented from being generated.

  Further, the present invention is not limited to the above-described thermal type printing apparatus, and can be applied to, for example, an ink jet type printing apparatus. Further, the paper used for printing is not limited to the tape T, but may be a long one. Alternatively, the print data may be generated by an external device such as a PC, and the tape printer 1 may acquire the print data. In this case, the length of the margin is also set on the external device side.

  Further, each component of the tape printer 1 described above can be provided as a program. It is also possible to provide the program stored in a storage medium (not shown). As the recording medium, a CD-ROM, a flash ROM, a memory card (compact flash (registered trademark), smart media, memory stick, etc.), a compact disk, a magneto-optical disk, a digital versatile disk, a flexible disk, and the like can be used.

  Further, regardless of the above-described embodiments, the device configuration, processing steps, and the like of the tape printer 1 can be changed as appropriate without departing from the scope of the present invention.
