Meanwhile, the printer 100 according to an exemplary embodiment may include a marker detection unit 180. The marker detection unit 180 includes a sensor 181 for recognizing a marker arranged on the printing paper.

As shown in FIG. 3, the printing paper P includes a front face F on which an output is printed, a front face F on the opposite side of the front face F, (R). At this time, a pressure sensitive adhesive may be applied to the rear surface R of the printing paper P and a rear surface (not shown) may be attached to the rear surface R to protect the applied pressure sensitive adhesive.

Here, a plurality of markers M may be repeatedly arranged on the rear surface R of the printing paper P. At this time, when the rear edge R of the printing paper P is attached to the rear surface R, the marker M is arranged on the opposite side of the rear surface R, .

Further, the printer 100 according to one embodiment may include a step count unit 190. [ The step count unit 190 can count the number of steps of the motor included in the paper conveyance unit 150 described above.

At this time, the control unit 110 can convert the number of motor steps counted by the step count unit 190 into the conveyance distance of the printing paper P or convert the conveyance distance of the paper into the number of motor steps, Can be performed.

The arrangement of the components of the printer 100 will be described in more detail with reference to the conveying direction of the printing paper P as shown in FIG. As shown in the figure, the printing paper P is conveyed in the sheet conveying direction by the rotation of the conveying roller 153. [ At this time, the sensor 181 may first be positioned on the rear side (R) side of the printing paper P with reference to the conveying direction of the printing paper P. Next, the print head 161 is positioned opposite to the front side of the printing paper P, and then the cutter blade 171 can be positioned subsequently. At this time, the position where the sensor 181 is arranged to sense the marker M is referred to as the detection position DP, the position where the print head 161 performs printing on the printing paper P is referred to as the printing position ( PP and the cutting position CP are expressed by the cutting position CP as shown in Fig. 4, the position at which the printing paper P is cut by the cutter blade is referred to as a cutting position CP, As shown in FIG.

However, not all of them are all embodiments, and depending on the embodiment, the sensing position DP may be arranged between the printing position PP and the cutting position CP. That is, the sensor 181 of the marker detection unit 180 may be disposed between the print head 161 and the cutter blade 171.

In the printer 100 according to an exemplary embodiment of the present invention, when the printing unit 160 prints one unit output on the printing paper, The feeder 150 feeds the print sheet until the markers to be cut first, that is, the markers to be cut, reach the cutting position of the cutter 170 after the position where the printing of the unit output is completed based on the feed direction of the print sheet. That is, the control unit 110 uses the markers arranged immediately after the position where the printing of the unit output is completed on the basis of the conveying direction of the printing paper as the cutting target markers so that the cutting target markers reach the cutting position Feed the paper. The control unit 110 may cause the cutting unit 170 to cut the printing paper after the marking target marker reaches the cutting position.

At this time, the control unit 110 controls the printing unit 160 (160) based on the position of the marker sensed by the marker sensing unit 180 to convey the printing sheet until the cutting target marker reaches the cutting position From the print completion time of the unit printout of the unit printout of the print sheet. The target conveying distance of the printing paper is a distance indicating how far the printing paper is conveyed in the conveying direction at the printing completion time of the unit output. Is the distance to which the print paper should be fed to reach

In order to calculate the conveying target distance, the control unit 110 may count or calculate at least one of the conveying distance of the printing paper or the number of steps of the motor, and may be used to calculate the conveying target distance. Specifically, the control unit 110 counts the feeding distance of the sheet conveying unit 150 while the printing unit 160 prints the unit output, and before the printing unit 150 finishes printing the unit output, When the marker is detected by the marker detection unit 18, the counted travel distance can be initialized. The control unit 110 counts the transport distance initialized when the marker is detected during printing, and when the printing unit 160 finishes printing the unit output, the control unit 110 can calculate the transport target distance using the counted transport distance have. At this time, the feed distance and the feed target distance may be calculated as the number of motor steps or may be calculated in actual distance units. That is, the control unit 110 counts the feed distance based on the number of steps of the motor counted by the step count unit 190. When the marker detection unit 180 detects the marker, the control unit 110 initializes the number of steps of the counted motor, The number of steps can be counted and the counted number of motor steps can be used as is or converted into a feed distance.

Here, the control unit 110 may calculate the conveying target distance by subtracting the conveying distance counted from the preset fixed value, in order to calculate the conveying target distance, and the predetermined fixed value may be determined differently according to the embodiment. At this time, the fixed value may be determined based on the distance between the sensing position DP and the cutting position CP in the embodiment as shown in Fig. The fixed value may also be determined by the distance between the markers as well as the distance between the detection position DP and the cutting position CP, as the case may be. At this time, even when the detection position DP is arranged between the printing position PP and the cutting position CP, the fixed value can be changed according to the distance between the detection position DP and the cutting position CP, . ≪ / RTI > At this time, the transport target distance can be calculated by subtracting from the fixed value.

Further, in another embodiment, the control unit 110 determines that the first feeding distance, from when the printing unit 160 starts printing the unit output, to when the sheet feeding unit 150 has fed the printing sheet, The marker sensing unit 180 may start sensing the marker when the marker sensing unit 180 senses the marker, and if the sheet conveying unit 150 has conveyed the printing sheet from the time when the marker sensing unit 180 senses the marker, And the paper transport unit 150 may transport the print paper until the second transport distance reaches a predetermined second predetermined distance.

In this alternative embodiment, the control unit 110 may ignore the marker even if the marker detection unit 180 recognizes the marker until the first transfer distance reaches a value obtained by subtracting the first predetermined distance from the estimated print length of the unit output, So that the sensing unit 180 does not start sensing the marker.

The first predetermined distance is set to a distance corresponding to the distance between the sensing position DP and the printing position PP and the second predetermined distance is set to a distance corresponding to the distance between the sensing position DP and the cutting position CP Can be preset to the distance. At this time, the detection position DP, the printing position PP, and the cutting position CP can be sequentially arranged.

That is, the control unit 110 performs printing only without detection of the marker until the conveying distance of the printing paper reaches a value obtained by subtracting the first predetermined distance from the estimated printing length, When the first marker is recognized after the detection of the marker reaches the value obtained by subtracting the predetermined distance, the distance between the sensor 161 and the cutter 181 at the position where the marker is recognized, that is, The printing paper can be cut after the printing paper is fed by the distance d1 + d2 from the printing position DP to the cutting position CP.

At this time, the controller 110 may count the number of steps of the motor as described above in order to count the first feed distance and the second feed distance. The controller 110 may reset the number of steps of the motor to count the second feed distance from the time the marker is recognized after the detection of the marker is started, and then count the number again.

On the other hand, in this alternative embodiment, the arrangement of the sensing position DP, the printing position PP and the cutting position CP is sequentially changed in the order of the printing position PP, the sensing position DP, and the cutting position CP The control unit 110 determines that the detection of the marker starts when the first feed distance reaches a distance in which the estimated print length of the unit output is increased by the distance between the print position PP and the detection position DP, The conveying of the printing paper can be performed until the second conveying distance counted from when the marker is detected reaches the distance between the detecting position DP and the cutting position CP.

That is, when the printing position PP is arranged in the order of the detection position DP and the cutting position CP, the control unit 110 detects the marker after reaching the value obtained by increasing the estimated printing length by the first predetermined distance The above other embodiment can be divided into two embodiments.

At this time, the predicted print length can be calculated in advance while converting the unit output, that is, the print data printed at one time, into the printable data type of the control unit 110. [

After the completion of the feeding and cutting of the printing paper on which the unit output is printed, the controller 110 controls the paper feeding unit 150 to move the printing paper in the reverse direction of the feeding direction, As shown in FIG.

At this time, the back-feeding distance may correspond to the distance from the cutting position CP to the printing position PP.

Accordingly, waste of the printing paper can be reduced, and printing of the next unit output can be started again from the position where the cutting target marker is cut as described above.

Hereinafter, a printing method of the printer 100 according to the embodiment will be described with reference to Figs. 5 and 6. Fig.

Here, the printing method according to the embodiment shown in FIGS. 5 and 6 includes the steps of time-series processing in the printer 100 shown in FIGS. 1 and 2. FIG. Therefore, the contents described above with respect to the printer 100 shown in Figs. 1 and 2 can be applied to the printing method according to the embodiment shown in Figs. 5 and 6 even if omitted from the following description.

First, in the embodiment shown in FIG. 5, when the printing of one unit output on the printing paper is started (S510), the printer 100 performs a step of counting the distance of feeding the printing paper while printing the unit output can do. For this, the printer 100 may count the number of motor steps (S520). Then, the printer 100 can detect the markers arranged on the print sheet for each motor step (S530).

The printer 100 determines whether or not printing is completed in parallel with the conveyance and printing of the printing paper of the printer 100, the count of the motor steps, and the marker sensing operation (S540). When the printing of the unit output is completed The counted feed distance or the number of motor steps is checked (S550), and a value obtained by subtracting the feed distance from the feed target distance of the print paper, that is, the predetermined fixed value is calculated and the print paper is further fed by the calculated feed target distance Step S560 is performed. Then, the printer 100 can cut the printing paper (S570).

On the other hand, if the marker arranged on the printing paper is detected while the printer 100 prints the unit output, the printer 100 initializes the counted feeding distance or the number of motor steps and counts the feeding distance or the number of motor steps again .

And repeats the process of counting the number of motor steps and counting the number of steps each time the marker is continuously detected during printing. When the printing is completed, the printing paper is further traversed based on the number of motor steps counted at the completion of printing, So that the printing paper can be cut.

In this case, referring to the distance between the detection position DP and the cutting position CP, the distance between the detection position DP and the cutting position CP, which is initialized every time the marker is sensed, It is possible to calculate the distance at which the marker to be cut reaches the cutting position CP, i.e., the conveying target distance. At this time, the fixed value for calculating the transport target distance can be determined by considering the interval between the markers as described above.

Meanwhile, in another embodiment, the printer 100 may start printing the unit output (S610), as shown in FIG. 6, and confirm the estimated print length of the unit output (S620).

At this time, the printer 100 counts the first feeding distance, which is the feeding distance of the printing paper while printing the unit output, and subtracts the first predetermined distance set in advance from the estimated printing length determined in step S620 It is possible to feed the sheet while confirming that the value reaches a certain value (S630). Here, the printer 100 can count the number of motor steps in the same manner as in the embodiment shown in Fig. 5 in order to count the first feed distance, and the feed distance can be counted in the number of motor steps or used for calculation.

On the other hand, when the first conveyance distance reaches a value obtained by subtracting the first predetermined distance from the predicted print length, i.e., the distance between the sensing position CP and the printing position PP, the printer 100 can start the detection of the marker (S640). Of course, according to the embodiment, the printer 100 can start detection of the marker only when the first conveyance distance reaches a distance obtained by adding the first predetermined distance to the estimated print length, as described above.

When the marker is detected on the printing paper after the marker is detected (S650), the printer 100 initializes the counted feeding distance, counts the feeding distance and the number of motor steps again, and counts the second feeding distance .

Next, the printer 100 determines whether the second conveyance distance at which the count is started when the marker is sensed is the distance between the sensing position DP and the cutting position CP, that is, the distance between the sensor 161 and the cutter blade 181 (S660), and then the sheet is cut (S670).

According to this method, since the markers arranged for the first time after the printing completion of the unit output are transferred to the cutting position (CP), it is possible to precisely cut the portion where the marker is located and prevent the printing region of the unit output from being erroneously cut.
