TECHNICAL FIELD

[0001] The present application relates to the technical field of inkjet printer printing control, in particular to a method for switching inkjet printer printing information through a GPIO port. BACKGROUND

[0002] At present, with the increasing demand for personalized products, the application field of inkjet printers is also becoming wider. In actual printing operations, there are often cases where multiple production lines share one inkjet printer. The products of each production line arrive randomly, and if the printing content required by each production line is different, manual switching of the printing information is needed. However, manual switching of the printing information is too low in efficiency and prone to errors.

[0003] Most inkjet printers currently come with a serial port or a network port for communication with external production line equipment. Therefore, many solutions for switching printing information involve sending the file name of the information that each production line needs to print through the network or serial port. This solution is relatively complex and requires high requirements for production line equipment, which needs to have the ability to develop codes. However, some production line equipment is too old and cannot communicate through these interfaces.

[0021] The technical solutions in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

[0022] In the description of the present application, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0023] The existing inkjet printer is equipped with multiple groups of GPIO ports when it is shipped, so that the user can communicate with the inkjet printer through these GPIO ports, such as switch printing, reset the counter, etc.

[0024] Referring to Figure 1 The embodiment discloses a method for switching printing information of an inkjet printer through GPIO ports, comprising the following steps:

[0025] Step 1: Turn on the information switching function of the GPIO port of the inkjet printer: set the function of the GPIO port as information switching in the software interface of the inkjet printer;

[0026] Step 2: Set the number of GPIO ports that need to switch information, which is determined according to the number of different printing information contents of the production line;

[0027] The calculation method is:

[0028] 2 n-1 <m≤2 n ,

[0029] Wherein, m represents the number of different printing information contents of the production line; n represents the number of GPIO ports that need to switch information.

[0030] In this embodiment, the number of different printing information contents of the production line is 8, that is, 8 production lines with different printing information contents share one inkjet printer, and the inkjet printer has a total of 4 GPIO ports for input, of which the default configuration is 2 GPIO ports for information switching and the other 2 GPIO ports for resetting the counter. The function of the GPIO port information switching is turned on through software, and the required number of GPIO ports is set. In this embodiment, m=8, so n=3, that is, the number of GPIO ports that need to switch information is set to 3, and the software will automatically switch one of the GPIO ports for counter reset function to information switching function.

[0031] Further, the software default configuration is to close the information switching function, and 2 of the 4 GPIO ports are used to reset the counter by default. If the printed information content contains two counters, the external control state of the two GPIO ports can reset the corresponding counter after the software collects it. Because the default information switching function is closed, the software will not respond to the change of the other two GPIO ports.

[0032] If 8 production lines share one inkjet printer, each production line has its own printing information content. Therefore, the information switching function of the GPIO port needs to be turned on first. Because it involves 8 different production lines of printing information, 3 GPIO ports are needed to distinguish the 8 printing information. However, only 2 GPIO ports are used for information switching by default. Therefore, the user needs to set the number of GPIO ports for information switching to 3 on the display screen interface. Then the software will switch one of the GPIO ports for counter reset function to information switching function. In this case, the state change of the GPIO port will not cause the counter to reset.

[0033] Step three, edit the information that each production line needs to print on the inkjet printer: according to the information content that 8 production lines need to print, edit the corresponding printing information on the display screen, and name the first letter of the file name as the corresponding production line number when naming the file, as shown in Table 1:

[0034] Table 1

[0035] GPIO0 GPIO1 GPIO2 value filename 0 0 0 0 0msg 0 0 1 1 1msg 0 1 0 2 2msg 0 1 1 3 3msg 1 0 0 4 4msg 1 0 1 5 5msg 1 1 0 6 6msg 1 1 1 7 7msg

[0036] Step four, connect the corresponding GPIO port to the corresponding production line equipment and wait for printing: connect the 3 information switching function GPIO ports of the inkjet printer to the corresponding production line equipment. When the corresponding production line equipment transports the product, it will set the GPIO port of the inkjet printer to the corresponding state in Table 1, such as 2msg. Therefore, the state of the 3 GPIO ports is 0, 1, 0. After the software detects the state change, it will automatically open and download the corresponding production line information, and print the corresponding information after detecting that the product is in place.

[0037] It can be understood that in other embodiments, if the user does not need the information switching function of the inkjet printer, but needs to reset the counter through the external GPIO port, the information switching function can be closed, and the default configuration can be used. Through the cooperation of software and hardware, the GPIO ports of the inkjet printer can be fully utilized to meet the different needs of different users.

[0038] In this embodiment, the development of the software can be realized by software developers according to the above description.
