Detailed Description

Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

It should be noted that the embodiments of the present invention and the technical features of the embodiments may be combined with each other without conflict.

In logistics management warehouse, transportation and distribution businesses and the like, a plurality of different business systems are involved, and the business systems generally have scenes of dynamically adjusting printing styles according to different business types and different merchants and printing paper. The current solutions are as follows:

different printing style processing programs need to be developed aiming at different service scenes, and corresponding printing functions also need to be developed if different merchants have different printing style requirements.

However, the above solution has the following major problems:

1. the development cost is high, each different service needs to independently develop a specific function, and the same service also needs to develop an independent function for a specific merchant;

2. the printing logic is not flexible enough, and needs to be modified to adapt when the printing requirement changes;

3. the maintainability is poor, and when the service scene is complex and the printing logic is complex, the system becomes unable to maintain.

Therefore, the data printing method of the embodiment of the invention provides a universal printing job life cycle management method, solves the problem that printing requirements of different service systems are variable in different service scenes, reduces the overall development cost and improves the maintainability of the service systems.

Fig. 1 is a schematic diagram of main steps of a data printing method according to an embodiment of the present invention. As shown in fig. 1, the data printing method according to the embodiment of the present invention mainly includes the steps of:

step S101: and configuring a service system and recording at least one printing template corresponding to the service system.

The data printing method of the embodiment of the invention can be applied to service platforms such as a printing management system, and can respectively carry out targeted configuration on each service system on the service platforms, so that each service system has a corresponding printing template. In addition, under the scene of accessing a plurality of service systems, data isolation is carried out according to the service systems, data such as data models, printing templates and the like are stored in the corresponding service systems, and only system responsible persons and system members of the service systems can access the corresponding data, so that the service systems are not influenced with each other.

In the embodiment of the present invention, step S101 may be implemented by: configuring a service system based on the service system number and the member information; responding to the definition operation of a system principal or a system member, recording a data model of a service system defined by the system principal or the system member and a data acquisition mode; recording a printing template created by a system principal or a system member, and setting a service system number, a printing template number, a template version number, a data model and a locking state of the printing template; establishing a binding relationship between the printing template and the printer; and responding to the starting operation of the printing client, and updating the local file system of the printing client.

For each business system, the service platform can perform printing related configuration such as operators, data sources, printing templates and the like on the business system. The operating personnel are the system responsible personnel, the system members and other personnel capable of editing the data source and the printing template, and can give corresponding rights to the system responsible personnel and the system members according to the requirements of the service system, for example, which editing operations can be executed by the system members, or the system responsible personnel can add the system members, and the system responsible personnel can also hand over the system to other members as responsible personnel; the data source refers to: a data model (namely a structure of printing operation data) used by the service system and a mode of acquiring data from the service system by a printing client are defined by a system person in charge or a system member in the service platform aiming at the service system; the system leader and system members may add or modify print templates for the business system. It should be noted that each print template is configured with at least one print client or a file output format, such as PDF, Word, Excel, or the like.

The print client acquires data from the service system in two ways, which are respectively: push type: the business system submits the organized data to a printing client; pulling type: and the printing client accesses the service system to acquire the printing data through the data acquisition interface defined in the data source. In addition, when the printing client is started, the service platform can check whether the printing template stored by the printing client has a new version or not, and if so, the printing template is downloaded to a local file system of the printing client for updating, wherein the local file system is used for storing the printing template.

In the embodiment of the present invention, the steps of recording the printing template created by the system principal or the system member, and setting the service system number, the printing template number, the template version number, the data model and the locking state of the printing template can be implemented by the following manners: authenticating a system principal or a system member based on member information of the service system, and calling a template designer for the system principal or the system member after the authentication is passed; responding to the editing operation of a system principal or a system member, acquiring a blank template newly built in a template designer by the system principal or the system member and a selected data model, and extracting a printing layout and a printing style from the edited blank template; previewing and displaying the edited blank template based on the data model, the printing layout and the printing style in response to the previewing operation of a system principal or a system member; responding to the storage operation of a system principal or a system member, storing the edited blank template as a printing template, and setting a service system number, a printing template number, a template version number and a locking state of the printing template; or temporarily storing the edited blank template.

The service platform can determine the business system to which the system principal or the system member belongs by utilizing the member information, the system principal or the system member can edit a printing template for the business system to which the system principal or the system member belongs, the printing template can be imported, created or modified and the like, the creation or modification of the printing template can be realized in a template designer called by the service platform for the system principal or the system member, the template designer can comprise but is not limited to design tools such as a PC client side or a web online designer, and the printing template can be previewed and temporarily stored in the editing process.

Meanwhile, the service platform supports version management, changes are synchronized to the service platform by submitting the printing template after the printing template is modified each time, the version number of the template is increased progressively when the printing template is submitted, and the service platform can be set to be not modified once the current version is submitted.

In the embodiment of the present invention, after the created print template, the following steps may be further included: authenticating a system principal or a system member based on member information of the service system, and calling a template designer for the system principal or the system member after the authentication is passed; locking a target printing template in a template designer in response to a modification operation of a system principal or a system member; in response to the editing operation of a system principal or a system member, extracting a modified layout and a modified style from the modified target printing template; previewing and displaying the modified target printing template based on the modified layout and the modified style in response to the previewing operation of a system principal or a system member; previewing and updating the target printing template, the template version number and the locking state thereof based on the modified layout and the modified style in response to the saving operation of a system principal or a system member; or, newly adding a printing template based on the modified layout and the modified style, and setting the service system number, the printing template number, the template version number and the locking state of the printing template; or temporarily storing the modified target printing template.

For the existing printing template, a system leader or a system member can update or modify the existing printing template, and the printing template can be previewed and temporarily stored in the editing process. It should be noted that, before updating or modifying, a printing template that needs to be operated (i.e. a target printing template) may be locked, and if the locking is successful, the printing template may be updated or modified, otherwise, subsequent operations cannot be performed, that is, mutual exclusion modification rules are supported, and each time the system attempts to lock the target printing template before modifying, the locking is successful and is modified, and if there are other users who are modifying, the locking fails. In the locking failure scene, the local printing template is read-only and can not be modified, so that the problem of mutual coverage data loss caused by simultaneously modifying the printing templates by a plurality of users is avoided.

Step S102: print job data is acquired from the print request.

The print job data may include a business system number, a print template number, a template version number, print data, and an output mode. When a service system has a printing requirement, the service system only needs to carry the used printing template information (namely, the service system number, the printing template number and the template version number), the specific printing content (namely, printing data) and the printing result (namely, a printing document is output to a printer or is output as a local file) in the printing request sent to the service platform, and does not need to independently develop a specific printing function.

In the embodiment of the present invention, step S102 may be implemented by: monitoring a printing interface; receiving a printing request sent by a service system through a printing interface; and acquiring a service system number, a printing template number, a template version number, printing data and an output mode from the printing request.

The printing client of the service platform can provide printing interfaces for all the service systems, the printing requests of the service systems can be sent to the printing interfaces, and the printing client can monitor the printing interfaces, timely receive the printing requests and analyze the printing requests to obtain printing operation data.

Step S103: and acquiring a printing template corresponding to the printing request according to the service system number, the printing template number and the template version number.

After the print job data is obtained, the print client can obtain the print template according to the needs of the service system, that is, a specific print template can be located through the system number, the print template number and the template version number provided by the service system.

In the embodiment of the present invention, step S103 may be implemented by: inquiring a service system number, a printing template number and a template version number in a local file system of a printing client; if the corresponding printing template exists, acquiring the printing template corresponding to the printing request from the local file system; and if the corresponding printing template does not exist, requesting the printing template corresponding to the printing request according to the service system number, the printing template number and the template version number.

Because the local file system such as the local cache of the printing client can store some used printing templates, after receiving the printing request, the corresponding printing template can be inquired from the local file system, if so, the printing template in the local file system is directly used for subsequent rendering and other operations, and if not, the corresponding printing template is inquired from the service platform. In addition, the printing client can support the coexistence of multiple versions of the printing template, so that the gray scale release of the printing template is realized.

Step S104: a print document is generated for the print request based on the print data and the print template.

The print client may perform rendering or the like on the print data based on the print template, thereby generating a print document of the print request.

In the embodiment of the present invention, step S104 may be implemented by: analyzing the printing template to obtain a printing style and a printing canvas; placing the printing data on a printing canvas according to a printing style to generate a printing document; outputting the printed document to a printer or as a local file based on the output mode; and feeding back the printing result.

After determining the printing template, the printing client analyzes the printing template to obtain a printing style and a printing canvas, places printing data in the printing canvas according to the printing style to generate a printing document, outputs the printing document to a printer for printing according to an output mode specified by a printing request, outputs the printing document as a local file for a user to use, and finally feeds back a printing result to the service system so that the service system knows whether the printing is successful or not.

It should be noted that the business system may be an internet-based delivery service system, which provides order business related to immediate delivery for the merchant, and the generated printed document may be various types of tickets corresponding to the order business, such as a receipt for the customer, a courier for the deliverer, or a receipt for the chef.

According to the data printing method provided by the embodiment of the invention, the configuration service system is adopted, and at least one printing template corresponding to the service system is recorded; acquiring print job data from the print request; acquiring a printing template corresponding to the printing request according to the service system number, the printing template number and the template version number; the technical means for generating the printing document for the printing request based on the printing data and the printing template overcomes the technical problems that different business systems have variable printing requirements in different business scenes, a large amount of labor and time cost can be consumed in a development link, and the maintainability of the business systems is poor, further solves the problem that the printing requirements of different business systems in different business scenes are variable, reduces the development and operation cost in the aspects of labor, time and the like, and improves the maintainability of the business systems.

In order to further illustrate the technical idea of the present invention, the technical solution of the present invention will now be described with reference to specific application scenarios.

In logistics management warehouses, transportation and distribution businesses, a plurality of business systems have similar functions of printing documents, labels and documents according to business data. If each system independently develops the printing function according to the specific requirements, the problems of repeated functions, high development cost and poor maintainability are brought.

According to the data printing method provided by the embodiment of the invention, the whole life cycle is divided into four stages of system access, template design, printer configuration and job printing, each stage is provided with a preset extension mechanism to take over the dynamic printing function of each system, so that the problem that the printing requirements of different service systems are variable in different service scenes is solved, the overall development cost is reduced, and the maintainability of the service systems is improved.

By accessing the printing management system, the business system does not need to independently realize all printing related functions, and can finish the rendering and printing work of the complex printing operation only by organizing business data according to the API provided by the printing management system. The development and operation cost is greatly saved, and the maintainability of the service system is improved.

The data printing method of the embodiment of the invention can divide the life cycle of the printing operation into 4 stages, namely a system access stage, a template design stage, a printing client configuration stage and an operation printing stage.

In the system access phase, different service systems can be registered in the printing management system through configuration so as to dynamically configure templates and analyze printing job data in subsequent processes, specifically:

the method comprises the following steps: the system administrator of the service system needs to provide service system numbers, member information and the like to register on the service platform, wherein the system administrator can add system members and can also designate other system members as administrators. The printing template, the data model and other metadata are isolated from each other among different business systems and do not influence each other. In addition, the service platform provides various identity authentication modes, and only the authenticated system principal and system members can log in the system to perform template creation, editing, publishing and printing operations;

step two: after the system person in charge or member logs in the system through identity authentication, a data source can be created. The data source defines a mode of acquiring the printing data in the service system and a printing data structure, namely a printing data model. Different traffic types of a traffic system may create different data sources. In the process of creating the data source, the service platform can import the data model basic initial structure from the business system and edit the data model basic initial structure. In the data source definition process, the data supply mode can be selected to be push or pull. The pull type requires the service system to provide data access modes, such as database connection, HTTP request address, file path and the like. The configuration determines the data acquisition mode of a printing client in a job printing stage in different modes. The pseudo code for the print data model class is shown in FIG. 2, and the data model and print template associated metadata descriptions are shown in Table 1.

TABLE 1

In the template design stage, a system principal or a system member configured in the service platform can serve as a template author, and the template author can design a printing template through a printing template designer after logging in the service platform, specifically:

the method comprises the following steps: when a template author logs in, the service platform can determine a business system to which the template author belongs according to identity information of the template author;

step two: the template author may create a new print template, at which point a data model may be selected via the template creation wizard, and the print style may begin with a blank template or may refer to an existing print template. The printing template comprises metadata information such as a system, a template number, a template version number (default initial state version number is 0), a data model, sample data, a locking state and the like, and a printing style;

step three: the template author can place the fields in the data model at specific positions of the blank template, edit the control in the blank template to define the field printing style, preview the printing effect at any time in the editing process, store the editing result in the form of a printing template file in a temporary storage state, store the editing result in the local PC of a template editor or a server, and open the file at any time for editing before submitting;

step four: after the edition is finished, the template author can submit the blank template after the edition to the service platform, once the blank template is submitted, an independent version number is generated for the template (namely, the printing template), the content is not modifiable, and the submitted template (namely, the printing template) can be used for printing;

step five: the template author can open a printing template file temporarily stored in the local of the template designer PC or open a printing template which is already released;

step six: after the issued printing template is opened, the printing template is in a read-only state, all contents cannot be modified, a template locking request (namely locking the target printing template) is submitted to a printing server by using an editing function, if the template is not locked by other authors, the locking is successful, and the current author can modify the template; otherwise, locking fails, the printing template still keeps a read-only state, and the user who edits the template at present is returned;

step seven: after the author finishes editing, submitting the change to the service platform through the submission template, wherein once the submission is successful, the template version is automatically increased in an increasing way, and the template state is automatically unlocked;

in addition, the system principal can force the unlocking of the template under editing in the service platform, and transfer the editing right to other system members.

A printing client configuration stage:

the method comprises the following steps: the members of the business system as printing operators can start a printing client at the PC where the printer is located, and the identity and the business system which the members belong to are determined by logging in.

Step two: and a printing operator configures the binding relationship between the printing template and the printer under the current business system through the printing client.

Step three: and the printing client generates system service, executes the system service in a silent mode in the background of the system, starts monitoring service and serves as an API (application programming interface) to receive the printing request from the service system.

When the printing client is started, whether the printing template with the configured printer has a new version is checked, and if the printing template has the new version, the printing template is automatically downloaded to a local file system.

In the job printing stage, the business system submits a printing job to a printing client for printing, specifically:

the method comprises the following steps: the business system needs to organize the printing operation data, including the information of the business system number, the printing template number, the template version number, the printing data, the output mode and the like;

step two: the business system submits the print job to the print client through an API (application program interface provided by the print client, e.g., rpc service remote call or HTTP request);

step three: the printing client determines a printing template and a version thereof according to the printing job information, if the number or the version number of the printing template described in the printing job exists in a local file system, the local file is directly used as the template to perform subsequent rendering operation, otherwise, the service platform is requested to provide the corresponding printing template, and if the number or the version number cannot be found, a printing error of the service system is returned;

step three: the printing client starts a printing rendering engine, analyzes the printing template, places the printing data at a specific position of a printing canvas in a specified style, and generates a final printing result document;

step four: the printing client determines to output the printing result document to a printer or a local file such as PDF, Word, Excel and the like according to the output mode in the printing operation;

step five: and the printing client feeds back the printing success or failure state to the service system.

As a preferred implementation manner, as shown in fig. 3, a service system access process of the data printing method according to the embodiment of the present invention is as follows:

a service system person in charge fills access information such as a data source, a data model, an access mode and the like in a printing metadata management service (namely a service platform);

if the service system provides an automatic data model synchronization mechanism, a schema service can be registered;

when the service system information is stored in the printing metadata management service, a method for acquiring entity fields in the schema service of the service system is automatically called, and (Getschema) entity and field information (namely a data model) are acquired from a source system (namely the service system);

after acquiring the information of the entity field, the printing metadata management service merges the information with the existing data model and the entity field in the current system (CreateFullDM), so as to ensure that the data model in the printing metadata management service is consistent with the source system;

the system leader may also edit the data model (EditFull DM) at the print metadata management service;

after the data model is modified, the modification needs to be validated through publishing (Publish), and entities and fields changed in the data model can be used in a subsequent template designer;

when the data model in the source system changes, the schema service of the service system can be recalled through a synchronization (Sync) operation to acquire the data model structure.

The template editing process involves two system roles and three components in the system, where:

role:

the source system can send a printing job to the printing client;

the template author: designing a printing style through a template designer according to a data model created by a system leader;

printing system components:

a template designer: designing a presentation style of the printing content according to the entity and field definition in the data model;

printing service: managing data models, printing metadata of templates (i.e. service platform);

the printing client side: and finishing the printing and rendering work according to the printing operation sent by the service system.

As a preferred embodiment, as shown in fig. 4, a print template editing process of the data printing method according to the embodiment of the present invention is as follows:
