Technical Field

The invention relates to the technical field of thermal printer heating control, in particular to a thermal printer heating control method and device and a thermal printer.

Background

The principle of a thermal printer is to coat a light-colored material (usually paper) with a transparent film and heat the film for a period of time to change the color to a dark color (usually black or blue). The image is generated by a chemical reaction in the film by heating. The thermal printer selectively heats the thermal paper at certain locations, thereby creating a corresponding pattern. Heating is provided by a small electric heater on the printhead that is in contact with the heat sensitive material. The heaters are logically controlled in the form of square dots or stripes by the printer, which when activated, produce a pattern on the thermal paper corresponding to the heating elements. The same logic that controls the heating elements also controls the feeding of the paper, thus enabling the printing of a pattern on the entire label or sheet.

When a conventional thermal printer prints data, the print data is converted into dot line data and then directly sent to the printer for heating. Although the method is simple, the phenomena that the printing effect is not ideal and the printed characters and pictures are not uniform tend to occur, so a control method for heating the thermal printer, which can realize uniform printing effect, is needed.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative only and should not be construed as limiting the invention.

As used herein, the singular forms "a", "an", "the" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and/or "comprising," when used in this specification, specify the presence of stated features, integers, steps, or operations, but do not preclude the presence or addition of one or more other features, integers, steps, operations, or groups thereof.

It will be understood by those skilled in the art that, unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the prior art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

Referring to fig. 1, the present invention provides a method for controlling heating of a thermal printer, the method comprising the following steps:

s100: and acquiring data to be printed.

An operator inputs characters and/or graphics to be printed into the thermal printer every time the operator prints, and at the moment, the thermal printer acquires data to be printed corresponding to the characters and/or graphics.

S200: and converting the data to be printed into heating points at corresponding positions, and combining all the heating points to form the data to be printed.

In this embodiment, data to be printed is converted into heating points at corresponding positions, and the characters and/or graphics formed by heating the heating points are the characters and/or graphics to be printed.

As shown in fig. 2, taking the printing of "king" word as an example, the data to be printed is converted into a heating point combination arranged in multiple rows, where the first bit, the third bit, the fifth bit, and so on of the heating point in each row are odd bits, and the second bit, the fourth bit, the sixth bit, and so on are even bits.

S300: when any line in the data to be printed is printed, heating points of any type in odd-numbered positions or even-numbered positions in the line are taken for heating, and then heating points of the remaining type are taken for heating.

In this embodiment, the odd-numbered heating points and the even-numbered heating points in the data to be printed are heated separately, and the odd-numbered heating points may be heated first and the even-numbered heating points may be heated later; the ink-jet printer can also heat heating points at even positions and then heat heating points at odd positions, so that the ink marks of printed characters or pictures can be more uniform as long as the aim of heating at intervals is fulfilled, and the printing effect is effectively improved.

Specifically, as shown in fig. 3-4, fig. 3 is a case of heating the heating points in odd-numbered bits in the data to be printed first, and fig. 4 is a diagram of the effect after two times of heating.

Furthermore, in the embodiment of the invention, the printable area is divided into a point set of m rows and n columns in advance, any point corresponds to a printable area coordinate information, wherein m and n are positive integers; the step of converting the data to be printed into heating points at corresponding positions, wherein all the heating points are combined to form the data to be printed, further comprises the following steps:

any heating point corresponds to the coordinate information of the printable area.

In this embodiment, the printable area is divided into a set of a plurality of points, and each point corresponds to coordinate information of rows and columns. After the data to be printed is obtained, the heating point converted from the data to be printed is any one of the point sets divided by the printable area, namely the heating point corresponds to the coordinate information of the printable area, and the odd number bit and the even number bit are distinguished conveniently according to the coordinate information.

Referring to fig. 5, in an embodiment of the present invention, before printing the data to be printed, a density reducing step S400 is further included, including:

s400 a: the heating points which are continuously adjacent in each row are divided into two groups.

S400 b: and removing any heating point in each group in the data to be printed.

Due to the principle of thermal printers, printing does not require the use of ink, and therefore, it is not possible to adjust the gradation of the printing effect by changing the ink density. In the embodiment, the printing density can be reduced on the basis of realizing printing of characters and/or graphics by a method of removing any one of the continuous black points.

Specifically, before executing the reduced density printing step, the judgment of the printing density is needed, and if the normal gray scale printing is needed, the step is executed directly according to the step S300; if low gray scale printing is required, the step S400 is performed and then the steps are performed. In step S100 and step S200, "acquiring data to be printed and converting the data to be printed into heating dots at corresponding positions" may be performed before the print density is determined, or after the determination is performed, the following steps need to be performed in step S100 and step S200 regardless of whether yes or after the determination is detected.

Further, as described in fig. 6 to 8, "removing any one of the heating dots in each group in the data to be printed" specifically includes:

the heating point groups of either one of the odd-numbered groups or the even-numbered groups of each row remove heating points located at the front in each group, and the heating point groups of the other one remove heating points located at the rear in each group.

As shown in fig. 6, fig. 6 shows a row of data to be printed, which is initially heated, and after the specific implementation of removing the heating dots in the present embodiment is adopted, the heating dots that should be heated are as shown in fig. 7, and fig. 8 is a graph showing the effect of performing "heating first by taking any kind of heating dots in odd-numbered bits or even-numbered bits in the row" on the basis of fig. 7.
