[0033] In view of the defects of existing thermal print heads, research has found that when existing thermal printers need to print multiple images on a piece of film, they will use a table layout to splice the images together. The borders of the table layout mostly use black lines, and the print head corresponding to black has the largest heating power. The hot spots of the print head are of the heat loss type. If this method is used for a long time, the hot spots of the print head corresponding to the black lines will have a shorter life than other hot spots. Once the hot spots are damaged, the existing technology cannot repair them, which will cause direct damage to the print head.

[0034] In view of this, the present application provides a thermal film printing control method and device, which are used to solve the technical problem of short service life of the print head of the existing thermal printer.

[0035] In order to make the purpose, features, and advantages of the invention of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described below are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] First, a detailed description of an embodiment of a thermal film printing control method provided by the present application is as follows:

[0037] See also Figure 1 , the present application provides a thermal film printing control method embodiment, comprising:

[0038] Step 101: Acquire a thermal film image and a printed image, based on a standard position of the printed image in the thermal film image.

[0039] Step 102: Determine the image offset interval of the printed image according to the standard position.

[0040] Step 103: Determine the image offset based on the image offset interval, so as to adjust the printing position according to the image offset and the standard position.

[0041] The image offset does not exceed the image offset range.

[0042] It should be noted that, according to the scheme provided in this embodiment, in the printing process of each thermal film, first, by acquiring the image of the thermal film and the actual printed content, the two images can be merged according to the general printing logic, so as to determine the standard position of the printed image in the thermal film and the image offset range, wherein the standard position mentioned in this embodiment is generally the center of the thermal film, and the image offset range is used to indicate the degree to which the printed image can be offset, so as to avoid the offset image exceeding the coverage range of the thermal film, and then the image offset is determined based on the value range of the image offset range, so as to adjust the printing position according to the image offset and the standard position, thereby changing the heating point responsible for printing the black line. Through the scheme provided in this embodiment, multiple printer heating points can be implemented to perform the black line printing task with the highest heat loss in turn, so as to avoid a certain heating point frequently performing the black line printing task resulting in excessive loss, accelerate the damage of the print head, and effectively extend the overall life of the print head.

[0043] Based on the above basic embodiments, in some embodiments, the technical solution provided by this application further includes the following contents:

[0044] Furthermore, in step 102, the image offset interval of the printed image is determined according to the standard position, and the steps may include:

[0045] According to the printed image corresponding to the standard position, the lateral edge deviation value between the printed image and the thermal film image is determined, and according to the lateral edge deviation value, the image offset interval of the printed image is determined.

[0046] It should be noted that, based on the printed image located at the standard position, the deviation value between the edge of the printed image and the edge of the thermal film image on the x-axis is determined, and based on the deviation value, the image offset interval of the printed image is determined, that is, the offset range [-x, x] of the printed image.

[0047] Further, based on the image offset interval, determining the image offset specifically includes:

[0048] According to the current image offset, the new image offset is determined in combination with the image offset interval and the preset image offset update condition information.

[0049] Among them, the image offset update condition information includes: an offset change threshold and an offset update trigger information. The offset change threshold is used to indicate the change of the image offset each time the image offset is updated, and can be configured in the form of a constant value or a calculation formula; the offset update trigger information is used to indicate the trigger condition of the image offset update action, and the number of thermal films printed can be used as a judgment condition.

[0050] Furthermore, the method provided in this embodiment may also include:

[0051] Step 104: If the new image offset exceeds the image offset interval, reset the image offset.

[0052] For example, Figure 2 As shown, assuming that -x is the initial offset, the offset change threshold is +1, and the offset update trigger information is set to: trigger each time a thermal film is printed, the following printing action logic can be obtained:

[0053] 1. The first image is offset by -x pixels, that is, it is offset to the left by x pixels. The position relationship is as follows Figure 2 Dark grey image;

[0054] 2. The second image is offset by -x+1 pixels, that is, offset to the left by x-1 pixels; ...

[0056] x, the xth image is offset by 0 pixels, that is, no offset, such as Figure 2 Black images; ...

[0058] 2x+1, the 2x+1th image is offset by x pixels, that is, it is offset to the right by x pixels, such as Figure 2 Light grey image;

[0059] 2x+2. Reset the image offset to -x, and then follow steps 1 to (2x+1) to continue film printing.

[0060] For another example, assuming that -x is the initial offset, the offset change threshold is +x, and the offset update trigger information is set to: trigger each time a pack of thermal film is printed, the following printing action logic can be obtained:

[0061] 1. The first packet is offset by -x pixels, that is, it is offset to the left by x pixels, such as Figure 2 Dark grey image;

[0062] 2. The second packet is offset by 0 pixels, that is, no offset, such as Figure 2 Black images;

[0063] 3. The third packet is offset by x pixels, that is, it is offset to the right by x pixels, such as Figure 2 Light grey image;

[0064] 4. Reset the image offset to -x, and then follow steps 1 to 3 to continue film printing.

[0065] It is understandable that the determination of the film package can be based on the RFID tag of each film package, and the RFID data of different films in different packages are different. When different RFID tags are identified, it can be determined that a package of film has been printed; or, based on the number of films a in each film package, when it is detected that a film has been printed, it can also be determined that a package of film has been printed.

[0066] The above is a detailed description of an embodiment of a thermal film printing control method provided by the present application. The following is a detailed description of an embodiment of a thermal film printing control device provided by the present application.
