Problems solved by technology

[0003] However, depending on the conditions of use, transient printing instability during printing, especially at the start of printing, may sometimes be noticeably observed
Therefore, the printing quality may decrease due to the unprintable or poor printing (for example, roughness, etc.) continuing until the printing becomes stable.

Embodiment Construction

[0016] Hereinafter, a thermal printer and a printing control method according to an embodiment will be described with reference to the drawings.

[0017] figure 1 It is an external view of the structure of the thermal printer 100 of embodiment.

[0018] The thermal printer 100 prints a predetermined image on a sheet, and issues the image-printed sheet. As an example of the sheet, label roll paper (Label Roll paper) is used.

[0019] Such as figure 1 As shown, the thermal printer 100 includes a display unit 200 , an operation unit 300 and a discharge port 350 .

[0020] The display unit 200 is an image display device such as a liquid crystal display or an organic EL (Electro Luminescence) display. The display unit 200 operates as an output interface, and displays characters and images. In addition, the display unit 200 may also operate as an input interface that accepts input of instructions from the user.

[0021] The operation unit 300 is configured using a conventional...

Abstract

Embodiments of the present invention relate to a thermal printer including a plurality of heating elements, a printing control unit, and a printing unit, and a printing control method. The heating element generates heat by application of electric power. The printing control unit applies first electric power corresponding to the number of heating elements not used for printing among the plurality of heating elements to the heating elements not used for printing. The printing unit performs printing using a plurality of the heating elements.

Description

technical field [0001] Embodiments of the present invention relate to a thermal printer and a printing control method. Background technique [0002] Conventionally, in a thermal printer, a plurality of heating elements built in a thermal head are heated by applying voltage to the heating elements, and printing is performed by utilizing the heat of the heated heating elements. Such a printing method is called a thermal transfer method, a thermal method, or the like. In these printing methods, conventionally, it is labor-intensive to ensure the printing quality as constant as possible under any usage conditions by adjusting the power applied to the heating element according to changes in ambient temperature, printed pattern, and printing speed. [0003] However, depending on the conditions of use, transient printing instability during printing, especially at the start of printing, may be remarkably observed in some cases. Therefore, the printing quality may decrease due to t...
