As used in the specification or embodiments and the appended claims, the singular forms "a," "the," and "the" are intended to include the plural forms as well, unless the context clearly dictates otherwise. It will also be understood that the term "and/or" as used in this specification in one or more embodiments refers to and includes any and all possible combinations of one or more of the associated listed items.

It will be understood that although the terms first, second, etc. may be used in one or more embodiments of this specification to describe various information, such information should not be limited by these terms. These terms are only used to distinguish the same type of information from each other. For example, a first could be termed a second, and similarly, a second could be termed a first, without departing from the scope of one or more embodiments of this specification. Depending on the context, the word "if" as used herein can be interpreted as "at the time of" or "when" or "in response to determining."

First, the terminology involved in one or more embodiments of the present specification is explained.

Cross-platform installation: refers to the software that can be deployed and installed under operating systems such as mac, windows, and linux.

Concurrent printing: The same computer can drive multiple printers to print at the same time.

Electron Framework: It is a framework for developing a cross-platform desktop application using traditional front-end technologies (such as Nodejs, Javascript, HTML, CSS). The desktop application refers to a program that runs on operating systems such as Windows, OSX, and Linux.

WebSocket: is a protocol for full-duplex communication over a single TCP connection.

New shopping malls: shopping mall activities under the new retail scene; new shopping mall operation activities relying on Internet technology. It mainly refers to a new retail model that integrates offline and online activities and deeply combines logistics.

With the continuous development of Internet technology, many browsers provide basic printing capabilities to perform printing operations. However, the requirements for high-efficiency and high-frequency printing scenarios are far from meeting the needs of printing. For example, in online shopping scenarios, The basic printing capabilities provided by browsers cannot meet the needs of high-efficiency and high-frequency printing.

Based on this, this specification proposes a customized printing client, which is a dedicated printing software; the advantages are that it can be used on a large scale and has strong stability. But the disadvantage is: the software does not support cross-platform, it is only used under the windows operating system, and must be equipped with a dedicated printer, and the customized print client does not support the ability to drive multiple printers.

And, this manual proposes another kind of WEB printing control, which supports printing programming interface, its advantages are: simple, strong stability, and can be customized programming; but the disadvantage is: it does not support cross-platform use, only limited to windows It is used under the operating system, and the version is lower and does not support the ability to drive multiple printers.

Therefore, in order to meet the printing requirements, a data processing method is provided in the embodiments of this specification, and the data processing method can be applied to a printing processing module. The printing processing module can be understood as a high-efficiency, high-frequency, and controllable operation software (client software). The client software implements a closed loop of carrying Internet services (such as online shopping services) and operating system print driver software in a web browser, can drive multiple printers to print at the same time, and has the ability to install and print across platforms.

Specifically, in this specification, a data processing method is provided, and this specification also relates to a data processing system, a computing device, a computer-readable storage medium, and a computer program. In the following embodiments They are explained in detail one by one.

Fig. 1 shows a schematic flowchart of a data processing system provided according to an embodiment of the present specification, wherein the system framework of the data processing system is mainly composed of four parts: a web service side, a printing client, a server and a printer . Specifically, as the initiator of the entire print task, the web service side can send a print request to the client software, wherein the print request carries the parameter of the order data to be printed, and the parameter can be understood as the order number. The client terminal acts as a link terminal (the terminal has client software deployed on it) and the transfer processing bridge of the printer. After receiving the print request sent by the web service side, it can send a request to the server terminal based on the order number carried in the print request. Request order data. The server is a part of processing web logic, and the server can send order data to the client software in response to a request sent by the client software.

After receiving the order data, the client software renders the order data to the client, so that the user perceives that the order data is being printed, and the perceived state can be sent back to the web server (ie, the web server).

After that, the client software starts to initiate the printing logic, obtains the current state of the printer, and pushes the print task (processing result) generated by the print page to the queue of the printer driver based on the current state. Once the printer is ready, it will automatically start printing and output. Paper.

The client software of the data processing method provided in this specification is developed using the Electron framework, so that the client software can support the installation and deployment of multiple operating systems, that is, it can support the use of the software under multiple operating systems. Secondly, when the print task is sent to the printer, the data processing method provided in this manual adopts the dynamic and concurrent push to multiple available printer queues, and has the ability to print concurrently, that is to say, a computer ( terminal) the ability to mount multiple printers to print at the same time. From the scheme design, it allows the user to select multiple available printers and record their printing status; and in the case of push, the number of tasks of each printer is obtained through command query, and the printing task is evenly distributed to each printer using an algorithm. Printer queue; it is essentially a process of giving it a "load balancing" capability, so that the printer is less "loaded" to work and avoid queue blocking. When the total number of prints is too large, the client software will cache the data (files to be printed) locally, and slowly dilute the number of print tasks by printing in batches or equally. Avoid the problem that some printer drivers exceed the transition queue and directly block printer printing.

Fig. 2 shows a flowchart of a data processing method according to an embodiment of the present specification, which specifically includes the following steps.

Step 202: Receive a data printing instruction, wherein the data printing instruction carries identification information of the data to be printed.

In practical applications, the data processing method provided in this specification can be applied to a print processing module that processes print operations, and the print processing module can be understood as client software that can process print operations.

Correspondingly, the to-be-printed data can be understood as data that needs to be printed. When the data processing scenarios provided in this specification are applied to different scenarios, the data to be printed is also different. For example, in an online shopping scenario, the to-be-printed data can be understood as order data; in a banking scenario, the to-be-printed data can be understood as bank running bills and the like. Correspondingly, the identification information can be understood as information that uniquely identifies a piece of data to be printed, and the identification information is not specifically limited in the embodiments of the description; for example, in the case of order data of the data to be printed, the identification information can be understood is the order number; in the case of the bank statement of the data to be printed, the identification information can be understood as the number of the bank statement. Correspondingly, the data printing instruction can be understood as an instruction instructing the printing process to perform a printing operation. In practical applications, the data print instruction may be an instruction sent by the print request module to the print processing module. The print request module can be understood as a mechanism, a platform, etc. that request the print processing module to perform a print operation. For example, the print request module may be understood as the above-mentioned web service, and the web service may be understood as an online shopping platform, an Internet service platform of a bank, and the like.

Specifically, the printing processing module can receive a data printing instruction instructing it to perform a printing operation, wherein the data printing instruction carries the identification information of the data to be printed.

The following describes the application of the data processing method in the print order data scenario, where the print processing module is the client software, the data to be printed is the order data, and the identification information of the data to be printed is the order number. Based on this, the client software can receive an order printing instruction instructing it to perform a printing operation, and the order printing instruction carries the order number of the order data.

In practical applications, the data print instruction can be sent by the print request module to the print processing module, thereby instructing the print processing module to perform a print operation; and in the process of the print request module sending the data print instruction to the print processing module, the print The request module needs to obtain the current state information of the print request module, and judges whether to send the data print instruction to the print processing module according to the current state information, so as to avoid the print processing module due to unconfigured completion, unprinted completion and/or print count Too many problems, etc., lead to the problem that the printing operation for the to-be-printed data cannot be performed, and the specific implementation is as follows.

The received data printing instruction includes:

Receive the status acquisition request sent by the print request module;

sending current state information to the print request module in response to the state acquisition request;

Receive a data print instruction sent by the print request module, wherein the data print instruction is an instruction sent by the print request module according to the current state information.

The state acquisition request can be understood as a request by the print request module to obtain current state information of the print processing module, and correspondingly, the current state information can be understood as information representing the current operating state of the print processing module. For example, the current state information can be understood as information representing whether the client software is installed, printing process information of the client software, and the like.

Specifically, in the process of printing the data to be printed, the print request module first sends a state acquisition request for the current state information of the print processing module to the print processing module; the print processing module receives the state acquisition request sent by the print request module. In the case of request, in response to the state acquisition request, send its own current state information to the print request module; the print request module, after receiving the current state information of the print processing module, judges the print processing module based on the current state information. In the case where the printing operation can be performed, the data printing instruction carrying the identification information of the data to be printed is sent to the printing processing module, and the printing processing module receives the data printing instruction sent by the printing request module, and executes the follow-up based on the data printing instruction. A print operation for the data to be printed.

Following the above example, the print request module is the web server. Based on this, the web server triggers the calling logic and sends a status acquisition request to the client software, and the client software sends its current running status information to the web server in response to the status acquisition request. Based on the current running status information, the web server can detect whether the client still has problems such as unfinished printing.

When the web server determines that the client software complies with the pre-printing preparations based on the current operating status information, it will send the order printing instruction carrying the order number to the client software; the client software receives the web service After receiving the order printing instruction sent by the terminal, the printing operation for the order data can be performed based on the order printing instruction.

In practical applications, in the process of printing the order data, the web server will also trigger the calling logic to first check whether the client software that performs the printing operation is installed on the terminal, so as to further judge whether the current environment conforms to the printing requirements. Prepare.

Step 204: Acquire the data to be printed according to the identification information of the data to be printed.

Specifically, after receiving the data printing instruction, the print processing module can acquire the to-be-printed processing that needs to perform the printing operation based on the identification information of the data to be printed carried in the data printing instruction. This avoids the problem of low processing efficiency caused by the web server not only executing web services but also sending data to the print processing module, and provides printing capabilities that meet the printing needs of high-efficiency and high-frequency printing scenarios. .

In an embodiment provided in this specification, the data to be printed can be obtained from a data providing module. Specifically, the obtaining the data to be printed according to the identification information of the data to be printed includes:

Generate a data acquisition request based on the identification information of the data to be printed, and send the data acquisition request to the data providing module;

Receive data to be printed sent by the data providing module in response to the data acquisition request, wherein the data to be printed is data determined by the data providing module based on the identification information.

The data providing module can be understood as an institution, platform, server, device, etc. that can provide data to be printed, for example, a server in a data processing system. In practical applications, after the user completes the purchase of goods through the web server, the web server generates order data for the user's purchased goods, and synchronizes the order to the server. Subsequently, when receiving a data acquisition request from the client software, the server queries the order data and sends the order data to the client software to perform a printing operation.

Specifically, after receiving the data printing instruction, the print processing module generates a data acquisition request based on the identification information of the data to be printed carried in the data printing instruction, and sends the data acquisition request to the data providing module; the data providing module After receiving the data acquisition request, in response to the data acquisition request, the identification information carried in the data acquisition request is acquired, and based on the identification information, the to-be-printed data matching the identification information is queried, and the to-be-printed data is queried. sent to the print processing module. The print processing module receives the to-be-printed data sent by the data-providing module, and subsequently performs a print operation on the to-be-printed data.

Following the above example, after receiving the order printing instruction sent by the web server, the client software can generate an order data acquisition request based on the order number carried in the order printing instruction, and send the order data acquisition request to the server; service When the terminal receives the order data acquisition request, in response to the order data acquisition request, based on the order number carried in the order data acquisition request, the terminal queries the order data that matches the order number from the order data stored by itself, and send the order data to the client software; after receiving the order data, the client software performs subsequent printing operations on the order data.

In the embodiment provided in this specification, the print processing module generates a data acquisition request based on the identification information of the data to be printed and sends it to the data providing module; and can receive the data to be printed sent by the data providing module in response to the data acquisition request, thereby avoiding the need for web The server not only needs to execute web services, but also needs to send data to the print processing module, which leads to the problem of low processing efficiency, and provides printing capabilities that meet the printing needs of high-efficiency and high-frequency printing scenarios.

Further, in an embodiment of this specification, in the process of sending the data to be printed to the print processing module by the data providing module, in order to avoid the problem of data leakage and preserve the security of the data, it is necessary to obtain a data request sent by the print processing module. Verification, if the verification is passed, the data to be printed will be sent to the print processing module. For example, in the scenario of bank statement printing, the client software deployed on the bank terminal will be sent to the server that provides bank statement data. After sending a data acquisition request for the bank flow data, the server will verify the data acquisition request to verify whether the client software that issued the data acquisition request is the client software authorized to obtain the bank flow data. In the case of passing the verification, the bank flow data is sent to the client software, so that the client software can perform subsequent printing operations, thereby avoiding the problem of data leakage and saving data security; the specific implementation is as follows .

The acquiring the data to be printed according to the identification information of the data to be printed includes:

Obtain the information to be verified, and the identification information of the data to be printed;

Generate a data acquisition request based on the to-be-verified information and the identification information, and send the data acquisition request to a data providing module;

Receive the data to be printed determined according to the identification information by the data providing module in response to the data acquisition request after verifying the data acquisition request.

The information to be verified can be understood as information representing whether the print processing module can obtain the data to be printed, and the subsequent data providing module needs to verify the data acquisition request sent by the print processing module based on the information to be verified; The information can be understood as account information configured with the print processing module, access keys configured with the print processing module, and the like.

Specifically, the print processing module can obtain the information to be verified configured and the identification information of the data to be printed carried in the received data printing instruction; generate a data acquisition request based on the information to be verified and the identification information, and send the data The acquisition request is sent to the data providing module; the data providing module responds to the received data acquisition request and verifies the data acquisition request based on the information to be verified carried in the data acquisition request; after the verification is passed, the data providing module is based on The identification information finds data to be printed that matches the identification information, and sends the to-be-printed data to the print processing module. The print processing module receives the to-be-printed data sent by the data-providing module, and subsequently performs a print operation on the to-be-printed data.

Following the above example, the information to be verified is the account information logged in the client software. Based on this, after the client software receives the order printing instruction sent by the web server, the client software can obtain its own logged-in information. account information of the account, and generate an order data acquisition request based on the order number carried in the order print instruction and account information, and send the order data acquisition request to the server; the server receives the order data acquisition request Next, based on the account information carried in the order data acquisition request, verify whether the account logged in the client software is an authorized account. If so, based on the order number carried in the order data acquisition request, query the order data that matches the order number from the order data stored by itself, and send the order data to the client software; the client software receives the order After the data is stored, the subsequent printing operations are performed on the order data. If not, an unauthorized notification is sent to the client software to prompt the person using the client to know that the client does not have permission to obtain order data.

Step 206: Determine a target printing template associated with the data to be printed, wherein the target printing template is obtained by adjusting the printing template to be processed.

In the specific implementation process, in order to ensure the regularity and format of the printed order data, after obtaining the data to be printed, the print processing module will determine the target printing module for the data to be printed, and then based on the data to be printed and the target printing module Generate files to be printed in a uniform format, so as to ensure the regularity of the printed order data. Based on this, the print template to be processed can be understood as a print template that needs to be adjusted. In practical applications, the client software will provide the original printing template (that is, the printing template to be processed), but the original printing template cannot meet different personalized needs. Different merchants need to meet their own needs in the process of printing orders. Print the template to print. Therefore, in order to meet the personalized needs of different merchants, the to-be-processed print template can be adjusted to obtain a target print template, and then based on the target print template, a to-be-printed file that meets different personalized needs can be generated. Based on this, in an embodiment of this specification, Before the determining the target printing template associated with the data to be printed, the method further includes:

receiving a template adjustment request for a to-be-processed print template, wherein the template adjustment request carries template adjustment information;

The to-be-processed print template is adjusted based on the template adjustment information to obtain a target print template.

Wherein, the template adjustment request can be understood as a request for adjusting the print template to be processed; correspondingly, the template adjustment information can be understood as information for adjusting the print template to be processed. For example, the template adjustment information may be information on operations such as modification, deletion, and addition of specific template elements in the to-be-processed printing simulation. The template element can be understood as a picture, text display area, default text, etc. in the print template. Based on this, the template adjustment information may be information for adjusting the position of the image and/or text display area in the print template to be processed. Alternatively, the template adjustment information may be information for modifying or deleting the default text in the to-be-processed print template.

Specifically, after receiving the template adjustment request for the to-be-processed print template, the print processing module can adjust the to-be-processed print template based on the template adjustment information carried in the template adjustment request in response to the template adjustment request, thereby obtaining the target print template , so as to meet different personalized needs and ensure the diversity and flexibility of printing templates.

In the embodiments provided in this specification, the print processing module may have multiple print templates, and when the data to be printed is acquired, a target print template associated with the to-be-printed data can be selected from the multiple print templates, So as to meet different personalized needs; specifically, the determining of the target printing template associated with the data to be printed includes:

determining the data type information of the data to be printed;

Based on the data type information, a target print template associated with the to-be-printed data is selected from the to-be-selected print templates.

Wherein, the data type information can be understood as information representing the type of the data to be printed; for example, when the data to be printed is order data, the data type information can be the order type; when the data to be printed is bank flow data , the data type information can be bank flow type.

Specifically, after acquiring the to-be-printed data, the print processing module determines the data type information of the to-be-printed data, and selects a target print template associated with the to-be-printed data from the to-be-selected print templates based on the data type information. For example, in a case where the data type information is an order type, a print template associated with the order data is selected from a plurality of print templates. In the case where the data type information is a bank statement type, a print template associated with the bank statement data is selected from a plurality of print templates.

Step 208: Generate a to-be-printed file based on the target print template and the to-be-printed data, and send the to-be-printed file to a file printing module for printing.

The to-be-printed file can be understood as a file that needs to be sent to the file printing module for printing; the file type of the to-be-printed file can be set according to the actual application scenario, which is not specifically limited in this specification. For example, the file type of the to-be-printed file may be Word, PDF, JPG and the like.

The file printing module can be understood as a device capable of printing the to-be-printed file, such as a printer.

Specifically, after obtaining the to-be-printed data and the target print template, the print processing module can fill the to-be-printed data into the target print template to obtain the to-be-printed file, and send the to-be-printed file to the file printing module for printing. In practical applications, the print processing module can send files to be printed to one or more file printing modules in batches, so that the file printing module can print the files to be printed in batches; or, the print processing module The files to be printed can be sent to multiple file printing modules in an evenly distributed manner, so that multiple printers can print the files to be printed in an evenly distributed manner.

In the embodiments provided in this specification, the data processing method provided in this specification allows the user to select multiple available printers and record the printing status of the printers. The number of tasks of each printer, and the printing tasks are allocated to each printer queue to achieve "load balancing" of the printers and avoid queue blocking. When the total number of prints of the printer is too large, the client software will cache the data (that is, the files to be printed) locally, thereby slowly diluting the number of print tasks. Avoid the problem of printer driving, exceeding the transition queue, and blocking the printing of the printer. Specifically, in the data processing method provided in this specification, there are at least two file printing modules;

Correspondingly, the sending the to-be-printed file to the file printing module for printing includes:

Obtain the current status information of each file printing module in at least two file printing modules;

Determine a target file printing module from the at least two file printing modules based on the current state information;

Sending the to-be-printed file to the target file printing module for printing.

Wherein, the current state information may be understood as information representing the current printing state of the file printing module, for example, the current state information may be the printing quantity of the printer. Correspondingly, in the case where the file printing module is a printer, the target file printing module can be understood as a printer capable of performing a file printing operation among multiple printers. In practical applications, some of the multiple printers may have many printing tasks, resulting in a load state; based on this, the client software can select a printer that can perform printing operations from multiple printers to print, Avoid problems that block the printer from printing.

Specifically, the print processing module can obtain the current state information of each of the at least two file printing modules; based on the current state information, the target file printing module capable of executing the printing task is determined from the at least two file printing modules, And send the file to be printed to the target file printing module for printing.

Following the above example, the client software can obtain the current status information of multiple printers, and based on the current status information of each printer, select unloaded printers that can perform printing tasks from multiple printers, and then the client software starts to initiate The printing logic pushes the printing tasks (tasks carrying the order files) generated on the client's print page to the queue driven by the printer. Once the printer is ready, it will automatically start printing and output paper, thus completing the printing of the order files. Work.

It should be noted that the queue of the pushed print task in the printer will return a print status, and the print status can be a value indicating whether the printing is successful or not. When the client software receives the print status, it will feedback the print status. Render the interface (such as the terminal screen) to the terminal, thereby prompting the user that the printing is successful.

In an embodiment of this specification, the sending the to-be-printed file to the target file printing module for printing includes:

Sending the to-be-printed files to the target file printing module in batches for printing.

Following the above example, when the client software sends the order file to the printer, it can push it to multiple available printer queues in a dynamic and concurrent manner, with the ability to print concurrently. In the process of pushing printing tasks in a dynamic concurrent manner, the printing tasks can be pushed to multiple available printer queues in batches in batches, thereby realizing flexible pushing of printing tasks and avoiding the problem of printer load.

Further, in an embodiment provided in this specification, the sending the to-be-printed file to the target file printing module for printing includes:

The to-be-printed files are evenly distributed to a plurality of the target file printing modules, so that the plurality of target file printing modules print.

Following the above example, in the process of pushing print tasks in a dynamic concurrent manner, multiple print tasks can be evenly pushed to multiple available printers in an evenly divided manner, so as to achieve flexible push print tasks and avoid printer load. The problem.

The data processing method provided in this specification actively obtains the data to be printed in the case of receiving a data printing instruction, and generates the to-be-printed file based on the to-be-printed data and the associated target printing template, and then generates the to-be-printed file. It is sent to the file printing module for printing, thereby avoiding the problem of low printing efficiency, and providing printing capabilities that meet the printing needs of high-efficiency and high-frequency printing scenarios.

The data processing method will be further described below by taking the application of the data processing method provided in this specification in a scenario where a merchant prints order data as an example with reference to FIG. 3 . Among them, FIG. 3 shows a process flow chart of a data processing method provided by an embodiment of this specification. Referring to FIG. 3, in an online shopping scenario, a user purchases a product sold by a merchant through a web server (such as mobile shopping software). In the case of a commodity, the web server needs to send a print instruction for the order data to the commodity to instruct the merchant to print the order data, and perform subsequent operations for commodity sales, such as commodity packaging, commodity delivery, etc., based on the printed order data.

Based on this, in the process of printing order data, the calling logic is first triggered on the web server to obtain the current running status of the client software; based on the current running status, check "whether the client is ready", if so, continue to check the " Whether the client is working", if not, it will prompt the merchant that the client is not ready, and end the printing process. Wherein, whether the client is ready can be checking whether the client software is installed on the commodity; whether the client is working can be checking whether the client software has not been printed. It should be noted that the client is the client software.

In the process of checking whether the client is working, if it is, it means that the client software has not finished printing, and it will “prompt at work” to inform the merchant that the client software has not finished printing. If not, the web server sends an order printing instruction to the client. The client receives and processes the order print instruction.

In practical applications, the web server checks basic checks such as whether the client is installed and whether the client has not finished printing. The purpose is to determine whether the current environment meets the pre-printing preparations and avoid the situation of printing counts. The client in the data processing method provided in this specification is developed based on the open source Electron framework, is independent of the web service side, and has the ability to perceive the bottom layer of the system. Since its framework is suitable for the same technology stack as web developers, developers can switch identities reasonably for research and development, and can support the installation and deployment of multiple operating systems, and support the use of the client software under multiple operating systems.

In addition, the communication in the process from web to client is real-time communication through WebSocket, and the web server will send necessary printing feature values to the client, such as the order number carried in the order printing instruction. Therefore, in the process of processing the order printing instruction by the client, after the client receives the order number, the client immediately displays the received data rendering to the merchant, starts processing the data, generates an order data acquisition request according to the order number, and executes the The order data acquisition request is sent to the server.

After receiving the order data acquisition request, the server processes the order data acquisition request; the server first verifies whether the request is authorized, that is, whether the request is initiated by an authorized account; The data is returned to the client, and the data processing result can be the result of the verification being passed.

After receiving the data processing result, the client determines that the processing is successful (that is, the order data is obtained successfully), and renders the data processing result to the client for display to the user.

If not, it is determined that the request is illegal, that is, the request is not initiated by an authorized account, and the server will prompt the merchant to be unauthorized and terminate the process directly. The processing result is returned to the client, and the data processing result may be a result indicating that the verification fails.

After receiving the data processing result, the client determines that the processing fails (that is, the order data acquisition is unsuccessful), and renders the data processing result to the client for display to the user.

That is to say, in the process that the client obtains the order data from the server, the server returns data to the client after a series of logical judgments, wherein the data includes the status data of successful or failed processing.

After the client obtains the order data, the client starts to initiate the printing logic; first, the client determines the order data printing template adapted to the order data; and fills the order data into the order data printing template, thereby obtaining order file. It should be noted that the order data printing template can be adjusted according to the needs of different merchants, so as to obtain a printing template that meets the personalized needs of different merchants.

Secondly, after obtaining the order file, the client calls the form to print, displays the order file to the merchant through the form, and generates a print task based on the order file. After that, the client side pushes the print task generated by the print page to the print driver queues of multiple printers, and once the printer is ready, it automatically starts printing and outputs paper. At the same time, the pushed queue will return a print status, which can be understood as the print result representing the success or failure of printing; after the client receives the status return, the client feeds this value (print result) to the client's rendering In the interface (that is, the client-side rendering result in Figure 3), it prompts the merchant to print successfully.

In the data processing method provided in this specification, a software development based on cross-platform concurrent drive printing is provided, wherein the software can be installed across platforms, can be installed under Windows, Mac, and Linux operating systems, and can drive multiple The printer prints at the same time. Therefore, in the new shopping mall printing scenario, the software can drive multiple printers to print at the same time, and has the ability to install and print across platforms. It further solves the problem that printing needs cannot be met in high-efficiency and high-frequency scenarios.
