Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of printing control methods, and in particular to a label parallel printing method, device, printer and storage medium. BACKGROUND

[0002] As shown in the prior art label printer (as shown in the prior art label printer), the following problems exist: Figure 1 Figure 1

[0003] 1. The label printer is usually configured with multiple interfaces (such as USB port, RS232 serial port, RJ45 network port, Bluetooth, WiFi, parallel port, etc.), but does not support simultaneous issuance of printing data for printing through multiple interfaces. If multiple interfaces simultaneously issue printing data for printing, data confusion and printing errors may occur.

[0004] 2. The prior art label printer usually has one built-in programming language (also known as a printing instruction), or has multiple built-in programming languages. However, the user must manually set or use tool software to select one of the printing instructions, and only the selected printing instruction data can be received and printed at any time. If another printing instruction is needed, the user must manually set or issue an instruction to select the other printing instruction.

[0005] 3. In actual application scenarios, multiple systems (such as workstation PCs and background management systems) require the use of multiple interfaces to multiplex label printing. In the event of interface data conflicts, instruction confusion, or when the label printer is moved to adapt to different host computer printing systems, the user must manually switch and set the instructions, which increases the user's learning cost and causes low efficiency.

[0006] In summary, although the conventional label printer is configured with multiple interfaces or multiple printing instructions, it can only process single-interface data at the same time and perform parsing and processing according to the set printing instruction. It cannot simultaneously support multiple-interface data reception and multiple-instruction parallel parsing for printing labels, and is equivalent to a single-interface single-instruction label printer. Therefore, it cannot be widely used with multiple interfaces and multiple instructions.

[0007] Therefore, the present application provides a label parallel printing method, device, printer and storage medium. SUMMARY

[0008] To solve the above problems, one of the technical solutions of the present application is as follows:

[0013] S4, reading the single-page label instruction data set from the instruction set FIFO buffer queue, parsing the single-page label instruction data set to generate reconstructed label page dot matrix data, and buffering the reconstructed label page dot matrix data to be printed;

[0014] S5, adding the reconstructed label page dot matrix data to the start and end identifiers and sending it to the label FIFO buffer queue for buffering, and arranging and arranging the print data in the form of label pages;

[0015] S6, extracting the data of each label page from the label FIFO buffer queue in the order of data entering time, and controlling the print head heating and motor driving to print the label.

[0017] S31, identifying the print instruction type to which the buffered data packet belongs according to a plurality of characteristic identifier sets of different label instruction data sets, or intelligently identifying the print instruction type to which the buffered data packet belongs through a lightweight neural network classification model.

[0023] The main controller adopts a microcontroller or microprocessor and realizes the label parallel printing method through multi-process and multi-thread parallel execution by running a multi-task real-time operating system.

[0026] The fourth technical solution of the present application is as follows:

[0027] A computer readable storage medium storing a computer program, the computer program being executed by a processor to realize the steps of the label parallel printing method.

[0028] The beneficial effects of the present application are as follows:

[0029] The present application establishes a dedicated data receiving buffer area for each communication interface, intelligently identifies and analyzes the instruction type of the printing instruction data, generates corresponding reconstructed label page dot matrix data, adds start and end identifiers to the label pages for printing data organization and arrangement, and finally extracts the data of each label page from the label FIFO cache queue for label printing, so as to realize the parallel printing of multiple interfaces and multiple instructions without manual switching and setting instructions, and fully improve the convenience of label printing.
