  • Patent number: 11052676
    Abstract: A printing device 1 includes a platen roller 7 which feeds a thermal tape 42, a thermal head 8 which performs printing on the thermal tape 42, and a control circuit 12. The control circuit 12 rotates the platen roller 7 backward to feed the thermal tape 42 backward in order to make a printing start area PT of the thermal tape 42 reach a backward feed position more away from an outlet 2b than a normal position NP of the thermal head 8. After that, the control circuit 12 rotates the platen roller 7 forward to perform printing using the thermal head 8.

  • Patent number: 10899147
    Abstract: A printing device 1 includes a platen roller 7 which feeds a thermal tape 42, a thermal head 8 which performs printing on the thermal tape 42, a half cutter 10 which performs a half cut on the thermal tape 42, and a control circuit 12. After the half cut is performed, the control circuit 12 controls the platen roller 7 to feed in a backward direction opposite to a direction of ejecting the thermal tape 42 into an outlet until a printing start area of the thermal tape 42 reaches a head position of the thermal head 8. The thermal head 8 performs printing on the thermal tape 42 after the printing start area reaches the head position by the feeding of the thermal tape 42 in the backward direction.

  • Patent number: 10336096
    Abstract: Provided is a printing apparatus which includes a thermal head having a plurality of heat generation elements whose temperatures are controlled by applying a voltage and performing printing on a printing medium and a head drive circuit being supplied periodically with a control signal and print data to control application of a voltage to each of the plurality of heat generation elements. One period of the control signal includes first and second voltage application control periods which are separated from each other. The first voltage application control period is a period in which the printing is performed by controlling the application of a voltage, and the second voltage application control period is a period in which the printing is not performed and a temperature of the thermal head is adjusted by controlling the application of a voltage.

  • Patent number: 10293621
    Abstract: A printing device includes: a thermal head including heater elements arrayed into a line along an array direction intersecting a conveying direction of a printing medium; and controller that causes the thermal head to print onto the printing medium based on multiple line print data, each of the multiple line print data being data into which print data is divided along the array direction. The controller performs either of a first energization control to energize the heater elements in one line cycle for printing based on a single line print data among the multiple line print data and a second energization control to energize the heater elements so that a non-energization period in which the heater elements are not energized is included in the one line cycle, depending on a temperature of the thermal head.

  • Patent number: 10232643
    Abstract: A printing apparatus includes a print head configured to perform printing on a print medium line by line based on print data, a drive motor configured to convey the print medium in accordance with printing of the print data on the print medium, a processor, and a width detecting unit configured to detect a width information of the print medium. In a case where printing is restarted after printing on the print medium by the print head is paused, the processor controls a rotation direction of the drive motor to be a reverse direction opposite to a direction before the pause of the printing and determines a rotation amount of the reverse rotation according to the width information of the print medium detected by the width detecting unit.
