It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or server that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
In order to make the objects, technical solutions and advantages disclosed in the embodiments of the present application more clearly apparent, the embodiments of the present application are described in further detail below with reference to the accompanying drawings and the embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the embodiments of the application and are not intended to limit the embodiments of the application.
In the following, the terms "first", "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present embodiment, "a plurality" means two or more unless otherwise specified. The following explanation is first made in the present embodiment for technical terms applied:
in the related art, there are many printer brands in the same company, and even if they are the same, different drivers are required to be used according to different machine models. If the files in the client of the user need to be output in a plurality of printers, a plurality of corresponding print drivers need to be downloaded, and the difficulty of printing and maintaining is increased.
For each printer, a corresponding printer driver needs to be installed on a client of a user, and the driver is installed on an operating system of the client by a professional person before the printing function can be used. The defect of the method is that the installation is complicated, and if a plurality of computers in an enterprise are used, a plurality of computers are required to be repeatedly installed. Different operating systems have different operating modes, high installation difficulty and high maintenance cost. Also, since the print is directly transmitted to the corresponding printer through the corresponding driver in the client in the related art, the print job cannot be managed in the middle.
In summary, the embodiments of the present application consider that there are at least the following disadvantages in the related art:
(1) for each client, the driver corresponding to the printer needs to be downloaded and configured one by one, and relevant background knowledge and relevant skills are needed. This problem is more prominent in the case where a plurality of printers needs to be arranged in the client. And the printer driver is not universal, further exacerbating the problem.
(2) There is no management and control link between the user printing and the printer paper output, so that the printing operation cannot be managed.
In view of this, embodiments of the present application aim to provide an intelligent printing method, where a private server is set to undertake a specific printing task, a client only needs to submit the printing task to the private server, and the private server can trigger a corresponding printer to execute and complete the specific printing task for the printing task submitted by a user and a selected printer, and the client does not need to install too many drivers and only needs to maintain communication with the private server, so that links of generating a printing task by the user and executing the printing task by the printer can be decoupled, and difficulty in using the printer by the user is significantly reduced.
Fig. 1 shows a flow diagram of an intelligent printing method provided by an embodiment of the present application, which provides the method operation steps as described above in the embodiment or the flow diagram, but may include more or less operation steps based on conventional or non-inventive labor. The order of steps recited in the embodiments is merely one manner of performing the steps in a multitude of orders and does not represent the only order of execution. When a practical system or server product executes, it may execute sequentially or in parallel (for example, in the context of parallel processors or multi-threaded processing) according to the embodiments or methods shown in the drawings, and the methods described above are applied to a private server and may include:
s101, a printing request sent by a client is obtained, and the printing request comprises first identification information of the client.
In the embodiment of the present application, a private server may be understood as a server with high security, and the private server may communicate with at least one client through an intranet. The private server may be deployed in company units or in a company-united territory. In particular, company a has three companies in three cities, and each company may deploy a private server. The private server may be configured to operate according to a plurality of printers and may trigger the plurality of printers to perform a print job.
The printing request comprises first identification information of a client, the first identification information is used for uniquely representing the identity of the client, the private server verifies the first identification information, and if the first identification information represents a legal user, printing permission can be opened to the client.
And S102, inquiring a printer queue according to the first identification information, wherein all the printers in the printer queue are currently available printers which are in communication connection with the private server.
If the client has the printing authority, the private server can inquire the printer which can provide the printing service for the client currently, so that a printer queue is obtained. In one embodiment, the private server may also be used to perform fine management on the printing authority of each client, for example, configuring each client as a printer providing the printing service. That is, the printers in the printer queue are all printers that are communicatively connected to the private server, are currently available, and are configured to provide printing services for the client. Different printers can be configured to serve different clients, which also facilitates load balancing of the printers.
Under the condition of obtaining the print request, private server inquires the printer queue, ensures that the printers in the queue are all available, and the printer that has the trouble or off-line can not be inquired out, avoids the printing failure that leads to because printer self has the problem, promotes and prints the success rate.
And S103, feeding back the printer queue to the client.
The user can trigger any printer in the printer queue in the client, that is, the printer can be selected as a target printer, so that the target printer can execute the specific printing task of the user.
And S104, acquiring a printing task sent by the client, wherein the printing task comprises a file to be printed and second identification information of a target printer, and the target printer is any printer in the printer sequence.
In order to enable the client to execute the above steps, in the embodiment of the present application, a unified printer is installed in the client in advance. The unified printer is configured to perform the following operations: displaying the printer queue; responding to a selection instruction of the printer queue, and determining second identification information of a target printer; generating a printing task according to the file to be printed and the second identification information; and transmitting the printing task to the private server.
And S105, releasing the printing task to the target printer to trigger the target printer to print the file to be printed.
In order to enable the private server to support the release of the print job, at least one printer needs to be added to the private server in the embodiment of the present application. Specifically, the method includes installing a driver file corresponding to the printer in the server; and correspondingly configuring the printer in the server. Correspondingly, the releasing the print job to the target printer to trigger the target printer to print the file to be printed includes: and processing the file to be printed based on the driving file corresponding to the target printer to obtain a first target file. And sending the first target file to an entity printer corresponding to the target printer based on the configuration of the target printer so as to trigger the entity printer to print the first target file based on the configuration.
Specifically, the private server may call a print driver and a configuration corresponding to the target printer to process the file to be printed, so as to generate print information (a first target file) and print configuration information, and transmit the print information and the print configuration information to the target printer, so that the target printer can finally print out the content in the file to be printed.
In the specific implementation process of the embodiment of the application, the client can download the unified printer and perform one-key installation. The client may initiate a print request to the unified printer, which may display a printer sequence by communicating with the private server. Referring to fig. 2, a schematic diagram of a printer sequence in a client is shown. The client may optionally select one of the above-described printer sequences as the target printer. Of course, the user may also select "save default configuration" so as to trigger the unified printer to remember the selection of the user, and in the case of acquiring the service request next time, the target printer is automatically determined, thereby further shortening the user operation path. The unified printer can be installed in various operating systems by one key, is different from a driver, and only needs to be communicated with a private server, so that a user can independently download and install the unified printer without the operation of a professional. The user can print using various printers depending on the configuration in the private server, and is no longer limited to locally added printers.
Please refer to fig. 3, which shows an architecture diagram of an embodiment of the present application. The client can upload the printing task by selecting the uniform printer in the private server, the private server can correspondingly process the file to be printed in the printing task, and then the entity printer corresponding to the target printer is triggered to complete the specific printing task. And because the private server feeds back the printer queue each time the user prints, the printers added in the private server can be ensured to be effective immediately. The management of the printer is only carried out on the private server, and each client does not need to carry out printer management any more, so that the management cost of the printer is reduced.
In some embodiments, the management of the print job may also be performed in the private server, for example, a print log is recorded, and the print log may include the first identification information of the client, the second identification information of the target printer, the related information of the printed file, the print time, and the like. The printing authority configuration information can also be carried out in the private server, for example, which printing servers can provide printing service for a certain client can be set, so that the load balance of each printing server can be controlled, and the printer resources can be reasonably utilized.
In some embodiments, the target printer may be a color printer, in which case the security of the printed document may be enhanced by the addition of an invisible watermark. The invisible watermark in the embodiment of the application is a watermark which is not easy to distinguish by naked eyes and can be presented by using a special tool. Because the aspect of information security is more and more emphasized in daily and office fields, in the printing technology, the printing source can be traced, other pages are prevented from being inserted, and the method is also an important security point in information security. Therefore, the embodiment of the application provides that the invisible information can be added into the printed paper, and then the information is restored by using a technology. Correspondingly, obvious watermark information is commonly added in the related scheme, so that the related scheme is easy to tamper and imitate. This does not provide a safety effect.
In order to add the invisible watermark, the private server according to the embodiment of the present application may further perform the following operations:
s201, transcoding the file to be printed to generate a file with a general format.
In the embodiment of the present application, a file in a PDF format may be used as the above-mentioned file in a general format.
S202, adjusting the color and transparency of the watermark obtained based on the invisible watermark information to obtain the target watermark.
Specifically, the private server may set the color of the watermark to (255, 255, 0) and the transparency to a range of 1% -10%, to obtain the target watermark.
And S203, adding the target watermark into the universal format file to obtain a target watermark file.
In the embodiment of the application, after the color is set to be (255, 255, 0) and the target watermark with the transparency set to be in the range of 1% -10% is combined with the file with the general format, the obtained target watermark file can achieve the watermark stealth effect, and the watermark is easily restored after the target watermark file is printed out subsequently.
And S204, processing the target watermark file based on the drive file corresponding to the target printer to obtain a second target file.
And S205, based on the configuration of the target printer, sending the second target file to an entity printer corresponding to the target printer to trigger the entity printer to print the second target file based on the configuration, so as to obtain a target watermark printing piece.
In the embodiment of the application, the watermark in the target watermark printing piece can be restored, specifically, the target watermark printing piece can be scanned to obtain a scanned piece; and adjusting the contrast of the scanning piece and performing enhancement processing on the scanning piece after the contrast is adjusted so as to display the watermark in the scanning piece.
In a specific embodiment, the target watermark print may be scanned by using an intelligent terminal to obtain a corresponding scanned piece. And carrying out contrast processing on the scanning piece so as to enable the target watermark to be highlighted. Specifically, the contrast process may be performed using a function Mat: (Mat & m, int rtype, double alpha 1, double beta 0) const, and the optimal value may be found by continuously adjusting the alpha and beta values to confirm the different effects. And then carrying out image histogram equalization EqualizeHist enhancement on the scanning element after the contrast processing until the target watermark can be distinguished by naked eyes.
Please refer to fig. 4, which illustrates a schematic diagram of the display effect of the invisible watermark. As can be seen from the left image of FIG. 4, the watermark in the target watermark printing piece cannot be seen by naked eyes, and the hidden watermark can be seen after the intelligent terminal is scanned, so that the anti-counterfeiting effect can be achieved.
