Problems solved by technology

The width of the commonly used thermal print head is mainly: 0.5 inches (12.7 mm), 2 inches (50.8 mm), 3 inches (76.2 mm), 4 inches (101.6 mm) and other sizes, and our commonly used A4, Standard size paper such as A5 cannot be thermally printed due to the insufficient width of the print head, and the special 8-inch thermal print head (203.2mm) print head is expensive and the price of the printer cannot be accepted by the market. At the same time, the printer itself Also due to slow printing speed, easy damage, short service life and other reasons, the practicability is not high, and the printer cannot split and print the picture, which limits the application range of the thermal printing method

Embodiment 1

[0026] Such as figure 1 As shown, the printing method of the multiple thermal head printer of the present invention includes the following steps:

[0027] Step 1: Obtain the image size and coordinate information, determine the number of print heads required to print the image, and perform stitching processing on the image;

[0028] Step 2: Re-arrange the picture pixels of the picture after the splicing process in Step 1 according to the position of the print head;

[0029] Step 3: Select and arrange the image pixels rearranged in step 2;

[0030] Step 4: Determine whether the processing is complete, if yes, the print head starts to print the spliced ​​image; if not, return to step 2.

[0031] First, use two or more thermal printer cores to splice into a larger size thermal printer, and then adjust and set the splicing parameters of each thermal printer core through PC or mobile phone software, and then according to the splicing parameters, according to the print head The splicing rela...

Embodiment 2

[0033] As in the printing method of a multi-thermal head printer shown in Embodiment 1, the difference is only that the ends of the effective printing area of ​​two adjacent printing heads are aligned or overlapped. The overlap or alignment of the ends of the effective printing area can effectively ensure the integrity of the picture during printing and prevent incompleteness.

Embodiment 3

[0035] As in the printing method of a multi-thermal head printer shown in Embodiment 1, the only difference is that in the first step, the obtaining of picture size and coordinate information refers to picture size, pixels, and colors. By obtaining the picture size and coordinate information, the subsequent editing of the picture can be effectively guaranteed.

Abstract

The invention discloses a printing method for a multi-thermal-head printer. The method comprises the following steps: obtaining size and coordinate picture information, judging the required number ofprint heads, and performing splicing processing on pictures; rearranging picture pixels of pictures after splicing according to the print head positions; and selecting and arranging the re-arranged picture pixels; judging whether the processing is completed, wherein if the judgment is completed, the print heads start to print spliced pictures, and if the judgment is not completed, returning to step 2. The printing method for the multi-thermal-head printer enables the small-size thermal printer to achieve the printing effect of a large-size printer, and facilitates the processing of the splicedpictures at the same time, thereby reducing the cost of thermal printing of large-size pictures.

Description

Technical field [0001] The invention relates to a thermal printer, in particular to a printing method for a multi-thermal head printer. Background technique [0002] For thermal printers currently in use, the printing width of the printer is limited by the width of the thermal print head and the method of thermal printing. The widths of the commonly used thermal print heads are mainly: 0.5 inches (12.7 mm), 2 inches (50.8 mm), 3 inches (76.2 mm), 4 inches (101.6 mm) and other sizes, while the commonly used A4, Standard size paper such as A5 cannot be printed with thermal printing due to insufficient print head width, while the dedicated 8-inch thermal print head (203.2 mm) print head is expensive and the printer price cannot be accepted by the market. At the same time, the printer itself Also due to the slow printing speed, easy damage, short service life and other reasons, its practicality is not high. The printer cannot split the picture for printing, which limits the applicat...
