Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Among the prior art, treat that the document of printing most can receive the restriction of printer type, when treating in the document of printing page inconsistency (direction or breadth) moreover, print the operation comparatively loaded down with trivial details, need the repeated setting of user many times, otherwise print the anomaly easily, automatic two-sided printing is especially good. In order to solve the problems, the printing control method, the printing control device and the printing control system provided by the embodiment of the invention can be realized by adopting corresponding software. The following describes embodiments of the present invention in detail.
The first embodiment is as follows:
referring to a flowchart of a printing control method shown in fig. 1, the method is executed by a user terminal, which may be a computer or the like, and the method specifically includes the following steps:
step S102, converting the document to be printed into a preset format file through the virtual printer, and determining the printing attribute information of the document to be printed. Wherein the virtual printer is installed in the user terminal.
The document to be printed is selected by the user, such as a word document, an excel document, a PDF document, a web page or a picture of the user. When a user prints a document, the user can receive a printing instruction input by the user (the user clicks a 'print' button), the virtual printer intervenes to process the document to be printed selected by the user, and the steps are started. In specific implementation, the virtual printer is pre-installed in the user terminal, and when a user prints a document, the user selects the virtual printer, can set and adjust the printing attributes on a virtual printer configuration interface, and performs printing operation. Considering that the types of the documents to be printed are numerous, in order to facilitate the uniform processing of the documents to be printed in the printing control process, the documents to be printed are uniformly converted into files with preset formats. Specifically, a document to be printed is input into the virtual printer, and a preset format file and printing attribute information which are output by the virtual printer and correspond to the document to be printed are received. This approach facilitates print control and also helps to improve print efficiency and reliability.
Regarding the preset format file, this embodiment provides an implementation manner: the preset format file is an enhanced metafile, and specifically, the document to be printed usually includes a plurality of pages, so the preset format file is a multi-page enhanced metafile. The enhanced graphic element file is a vector picture format defined by Microsoft, and the enhanced graphic element file is a vector diagram, so that the enhanced graphic element file can be well adapted to different resolutions, and the presentation of printing content details is convenient to ensure. Of course, files in other formats may be used, and are not limited herein.
Step S104, setting a reference standard of a preset format file according to the application environment information of the entity printer; and creating a printer device context based on the reference benchmark; the reference datum comprises a datum page and datum information; the entity printer is connected with the user terminal and used for printing a document to be printed.
The physical printer for printing the document to be printed may be selected by a user, and the physical printer may control output according to the application environment information. Specifically, the application environment information may be understood as initialization and operating environment information (DEVMODE) of the printer device, and the DEVMODE data structure includes information on device initialization and printer environment. In practical application, the top page of the document to be printed can be used as a reference page, the DEVMODE of the printer is reset according to the printing attribute information, and the reset DEVMODE is used as the reference DEVMODE, that is, the reference information. A printer device context may be created based on the baseline information.
A device context is a Windows data structure that contains rendering property information about a device (e.g., a printer). All draw calls are made through device context objects that encapsulate the Windows API for drawing lines, shapes and text. The device context allows device-independent rendering in Windows. The device context may be used to draw to a screen, printer, or metafile.
And step S106, in the process of controlling the entity printer to print and output the preset format file, adjusting the reference datum and/or the printer device context according to the current printing page, so that the entity printer prints the current printing page according to the adjusted reference datum or printer device context.
The preset format file usually includes a plurality of pages to be printed, the method usually controls the printing output of the current printed page based on the reference standard or the context of the printer device, and the front and back pages in the preset format file may be different (different sizes or different page directions), if the printing control is performed only by referring to the fixed setting, the phenomena of abnormal printing, disordered typesetting and the like are very easy to occur, so in the step S108, the reference standard and/or the context of the printer device is adjusted according to the current printed page, and the entity printer prints the current printed page according to the adjusted reference standard or context of the printer device. That is, the reference benchmarks and printer device context may be reset according to the condition of the current printed page to ensure that each printed page is output normally. This kind of automatic adjustment's mode has effectively promoted the printing reliability, also need not artifical the setting simultaneously in front and back page simultaneously, can automatic adjustment print, has simplified manual operation, has promoted printing efficiency.
In summary, the printing control method provided in the embodiments of the present invention converts the document to be printed into the preset format file, and then correspondingly sets the reference standard of the preset format file in combination with the application environment information of the entity printer, and creates the context of the printer device, so that multiple types of entity printers can be compatible with the document to be printed, and the limitation of the type of the printer on the document to be printed and the corresponding setting process required by manual work in the prior art are alleviated. The method supports automatic double-sided printing of common documents which are transversely and longitudinally mixed, can perform corresponding adjustment setting on a reference datum and/or the context of printer equipment according to a current printing page, controls the entity printer to print the current page based on the adjusted setting instead of controlling the whole document to be printed according to fixed setting, effectively improves the printing reliability and slows down the waste of paper; compared with the complicated process of manually adjusting the pages in the prior art, the method for correspondingly adjusting the pages in the document to be printed has the advantages that the printing efficiency is improved, and the printing operation of a user is simplified.
In practical applications, for convenience of understanding, a specific implementation of step S106 is given below, wherein the step of setting the reference standard of the preset format file according to the application environment information of the physical printer includes:
(1) according to the printing attribute information and the home page information of the preset format file, resetting the application environment information of the entity printer, and taking the reset application environment information of the entity printer as reference information; the home page information comprises a home page breadth and a home page direction;
(2) and setting the home page of the preset format file as a reference page.
Considering that the front and back pages in the document to be printed may have different sizes or widths, such as a first page longitudinal direction, a second page transverse direction, a third page longitudinal direction and the like; also, such as the first page is A3 format, the second page is a4 format, etc., the step of adjusting the reference datum and/or printer device context according to the current printed page in step S106 may be performed according to the format or orientation of the current printed page, with reference to the steps of:
judging whether the breadth of the current printing page is the same as that of the reference page or not;
if not, adjusting the reference information based on the breadth of the current printing page, and modifying the reference page to enable the modified reference page to be the current printing page.
Further, the printer device context may be reset according to the adjusted reference information.
(II) judging whether the direction of the current printing page is the same as that of the reference page or not;
if not, determining the angle of the coordinate system for rotating the context of the printer device according to the angle difference between the direction of the current printing page and the direction of the reference page, and rotating the coordinate system according to the angle.
Such as rotating the coordinate system of the printing context by 90 degrees or 270 degrees according to actual conditions, and then inputting the content of the current printing page into the context of the printer device, so as to ensure that the content of the pages in different directions can be normally output to the paper.
In order to facilitate subsequent printing, the method further comprises the following steps: and after the printing of the current printing page is finished, restoring the coordinate system of the context of the printer device. That is, after printing is completed, the coordinate system of the context of the printer device may be restored, so as to determine the rotation angle of the coordinate system of the context of the printer device later.
It should be noted that, the above steps for determining whether the breadths are the same and whether the page directions are the same are not limited to the execution sequence. In the process of controlling the printer to print, when the current page and the back page are different, the reference standard and the context of the printer device are also adjusted accordingly. When the front and back of the printed page are different, two processing modes exist: (1) adjusting the device context, such as rotating a coordinate system angle of the device context. (2) The reference information is directly adjusted. The context of the printer device can be used alternatively or simultaneously according to page differences, such as after adjusting the reference information, and the adjusted reference information is also used for resetting the context of the printer device.
The printing control method provided by this embodiment executes step S108 in a loop until all pages to be printed of the document to be printed are printed.
In addition, in view of the prior art, if people want to add watermark content to a page to be printed, special editing software is mostly needed to perform pre-editing setting on a document to be printed, so as to form a document to be printed with a watermark, and then print the document with the watermark by using a printer. Not only is time and effort spent, but also the document to be printed is changed. Based on this, the method provided in this embodiment may further include the following steps:
(1) acquiring watermark content and watermark configuration; the watermark configuration includes a combination mode, a watermark position, a watermark layout or a watermark effect. The combination mode can be that the watermark content is arranged at the lower layer of the printing content or the watermark content is arranged at the upper layer of the printing content.
(2) And combining the watermark content with the preset format file according to the watermark configuration in the process of drawing the preset format file into the context of the printer equipment.
By adopting the method, the user does not need to add the watermark to the document to be printed through editing software in advance, and can directly set (or adopt default setting) when the document to be printed is printed, such as presetting watermark content, the size, the color, the rotation angle, the position or the effect of the watermark, and the like. During the printing of the document by the printer, the watermark content is automatically combined with the printed page and output. The method can achieve the effect that the electronic version to-be-printed document stored in the user terminal has no watermark, and the paper version document which is printed and output and corresponds to the to-be-printed document is added with the watermark, can better meet the user requirements, and saves the time, the energy and the money cost for searching and learning the software for adding the watermark or purchasing the printer supporting the watermark.
Example two:
for the printing control method provided by the foregoing embodiment, for convenience of understanding, the present embodiment provides an example of practical application, and the printing control method is further described and explained, wherein for the explanation of part of the contents (such as the context of the printer device, DEVMODE, etc.), reference may be made to the foregoing embodiment, and no further description is provided herein. It should be understood that the present embodiment provides only one embodiment, but is not limited thereto.
On the microsoft Windows operating system, a virtual printer program is developed and installed on a designated computer (user terminal).
When a user prints a document, a virtual printer is selected for a printing operation. As shown in the processing diagram of the virtual printer in the printing control method shown in fig. 2, the print content is converted into the multi-page enhanced metafile and the printing attributes after being processed by the virtual printer. And storing the multiple pages of enhanced metafiles and the printing attribute information into a local computer for subsequent printing. The enhanced metafile is a vector picture format defined by microsoft, and can ensure the presentation of the details of the printing content.
After the conversion operation is finished, the virtual printer creates an actual printing module process and notifies the directory path for storing the enhanced primitive file to the actual printing module process. The actual print module process enumerates all printers currently on the computer and presents them to the user, so that the user can select the designated printer (the physical printer in the foregoing embodiment) to perform the actual print output.
Referring to fig. 3, a schematic flow chart of an actual printing module process in a printing control method includes the following steps:
step S302 sets reference information and a reference page, and creates a printer apparatus context. Specifically, the actual printing module acquires the DEVMODE of the entity printer selected by the user, and resets the DEVMODE of the entity printer according to the printing attribute generated by the virtual printer, the size of the top page of the document to be printed and the page direction, wherein the DEVMODE of the entity printer is used as a reference DEVMODE, and the top page is used as a reference page. The printer device context of the printer is created using the reference DEVMODE. The reference DEVMODE is reference information.
Step S304, the reference information and the reference page are adjusted according to the first determination condition, and the printer apparatus context is reset. Specifically, the first determination condition is: in the process of printing the page, if the breadth size of the current printing page is different from the breadth size of the reference page, modifying the reference DEVMODE by using the breadth size of the current printing page, resetting the context of the printer equipment by using the modified reference DEVMODE, and modifying the reference page into the current printing page.
In step S306, the coordinate system of the printer apparatus context is adjusted in accordance with the second determination condition. Specifically, the second determination condition is: in printing a page, if the paper orientation of the current printed page differs from the reference page, the coordinate system of the printer device context is rotated, for example, by 90 degrees or 270 degrees, depending on the paper orientation difference of the current printed page and the reference page. And then the page content is output to the printer device context, and the step can ensure that the pages in different directions can be normally output to the paper. After printing is completed, the coordinate system of the printer device context is restored. Of course, if the front and rear paper directions are the same, the rotation process is not performed.
Step S308, printing page content and rendering watermark content. Specifically, in rendering the page content to the printer device context, the watermark content may be rendered in the printer device context before or after rendering the page content. Rendering the watermarked content before, creates the effect that the watermark is at the lower layer. After that, the watermark content is drawn, so that the effect of the watermark on the upper layer is formed.
In practical application, the actual effect of the watermark can be customized, during the process of drawing the watermark, customized characters or images can be drawn on the context of the printing equipment according to a customized arrangement mode to form different distribution forms of the watermark in a page, and parameters such as the size, the color, the rotation angle, the position, the color depth and the like of the watermark content can be adjusted according to configuration to form different watermark output effects. Of course, rendering the watermarked content is an optional function.
Through reasonable setting of printer initialization and running environment information (DEVMODE), most printers can have better compatibility with documents to be printed, limitation of printer types to the documents to be printed in the prior art is relieved, and the process of corresponding setting of different types of printers manually required is also relieved. And the mode of correspondingly adjusting each page in the document to be printed also better improves the printing efficiency and simplifies the printing operation of the user. Particularly, the automatic double-sided printing of the common transverse and longitudinal mixed document is supported, so that the operation of a user is simplified, the effective number of double-sided printing pages is increased, and the use amount of paper of the user is reduced.
The generation of the document watermark is integrated into the output part of the system, so that a user can conveniently carry out uniform watermark setting operation and various watermark forms, the printing requirements of the user can be better met, and the time, the energy and the money for the user to find and learn to edit software to add the watermark or purchase a printer supporting the watermark are saved.
Furthermore, the addition of the watermark is integrated into the document output part, so that a user can conveniently carry out uniform watermark setting operation, various watermark forms are supported, the printing requirement of the user can be better met, the user does not need to add the watermark into the document to be printed through editing software in advance, and the time, the energy and the money for the user to search and learn the editing software to add the watermark or purchase the supported watermark printer are saved.
