Description

Image adjustment control method and device suitable for preprinted paper Technical field

The present invention relates to the technical field of image formation, and in particular to a portrait adjustment control method suitable for preprinted paper and a corresponding control device.

Background technique

With the rapid development of printing technology, we print documents, edit materials, etc. through printing devices in our daily work and life.

In many occasions, such as hospitals and banks, there is a special need for printers. In these occasions, it is often necessary to print text or images waiting for print data to a specific position on preprinted paper. Here, preprinted paper refers to a form printed in advance. And/or some information on paper, such as hospital test sheets, bank charge certificates, etc. The hospital prescription example shown in Figure 1 is pre-drawn with a form on a blank sheet and printed with the words "name", "age" and "prescription" on a specific unit. When the doctor sees the patient The single-time computer converts the patient's name, age, and prescription data input by the doctor into the document data to be printed, and the document data to be printed is printed by the printer at the corresponding blank unit of the prescription example table, but this is in advance The method of printing data on the printing paper often has the problem of offset of the printing position, as shown in FIG. 2, wherein the text of the bold portion such as Zhang San, 33 years old, etc. is the data of the document to be printed printed by the printer, which can be clearly It is seen that the data of these documents to be printed are shifted to the "prescription" column of the preprinted paper, which is greatly deviated from the printing effect we actually hope to obtain. At this time, the user needs to be able to adjust the document data to be printed on the preprinted paper so that the print position of the document data to be printed on the preprinted paper conforms to the user's expectation.

At present, the mainstream solution on the market is to manually adjust the print position on the print driver interface after the user visually observes the print offset. Although this can solve the technical problem of the print position shift to a certain extent, the user needs to Perform a printing operation before adjusting the print position. Observe whether the document data to be printed can be printed on the pre-printed paper according to the printed image effect. If there is a deviation, estimate the corresponding deviation value, and then further print drive. Adjusting the print position of the interface is not only time-consuming and laborious. If the user estimates the error, it may happen that the print position adjustment setting is improperly required to perform multiple adjustments and repeated printing, which is not conducive to the user body. The test seriously wastes the precious time and energy of the user.

At this stage, there is no very good way to solve the problems mentioned above. In most cases, the user can only repeat the print-observation-adjustment step to obtain the print content that meets the user's expectations. There is no image adjustment control method that is effectively applied to the pre-printed paper, so that the user can The print position of the printed document data on the preprinted paper is previewed before the official printing, so that the printed content that meets the user's expectations is obtained at one time.

detailed description

Those skilled in the art understand that in order to solve the technical problem that the user cannot adjust the position of the image on the preprinted paper before the official printing, the technical solution of the present invention is to provide an adjustment of the printing position of the document data to be printed before the printing operation. s solution. Through the technical solution provided by the invention, the printing efficiency of the user can be greatly optimized, and at the same time, the printing position accuracy of the document data to be printed on the preprinted paper is effectively improved. Specifically, in a preferred embodiment of the present invention, it is appropriate to observe or recognize whether the document data to be printed can be printed on the preprinted paper by the preview interface of the preview adjustment module or the automatic recognition function of the computer recognition module before the printing operation is performed. Position, and adjust the position of the document data to be printed based on the observation or recognition result, thereby realizing the adjustment of the print position.

3 shows a flow chart of a portrait adjustment control method suitable for preprinted paper for adjusting a document to be printed in a printer so that the document data to be printed is accurate according to the first embodiment of the present invention. Printing onto the preprinted paper, specifically, first performing step S101 to acquire preprinted paper data. More specifically, the pre-printed paper data includes pre-printed characters, images, or a combination of both on the current printing paper, for example, the hospital prescription single table shown in FIG. Further, the pre-printed paper data is acquired based on an image acquisition device including a scanner, a camera, and the like. In a preferred embodiment, the operating system acquires the pre-printed paper data based on a scanner installed in the printer, the operating system being driven by a print driver The module sends request information for obtaining the pre-printed paper data to the printer and receives feedback information sent by the printer, the feedback information corresponding to the instruction information, including the printer invoking the pre-printed paper data acquired by the scanner scan.

Before/simultaneously/after performing the step S101, the process proceeds to step S102 to acquire document data to be printed. Specifically, the document data to be printed includes a data distribution of a printable area of a document to be printed on a specific paper size. More specifically, the data distribution is obtained based on the first application layout. Further, the first application is an application (such as word, excel, etc.) that opens the document to be printed, and is used to open the document to be printed and obtain corresponding document data to be printed. Preferably, the first application is based on a structure variable of a Graphics Device Interface (GDI) module in a device driver interface (DDI), and a print driver module and an operating system perform information transmission. Thereby, the document to be printed is typeset. In a preferred example, the first application passes the relevant parameters of the document to be printed that are opened by the DEVMODE structure in the GDI module to the print driver module, and then acquires the corresponding variable value of the GDIINFO structure on the operating system. And combining the font attributes set by the user in the first application to perform layout output on the printed document data, wherein the DEVMODE structure includes parameters representing paper size, print resolution, paper length and height, paper type, and the like. a set of variables, the GDIINFO structure is a set of variables including parameters representing a system version of the operating system, basic device information, resolution, printable area, print paper size, font, and text, and some of the GDIINFO structures The variable values are obtained by the print driver module after performing a series of processing (including legality verification, range calculation, unit conversion, etc.) on the relevant parameters transmitted by the first application through the DEVMODE structure.

Next, step S103 is performed to determine whether the document data to be printed needs to be adjusted based on the pre-printed paper data and the document data to be printed. Specifically, the operating system makes a determination based on user instructions. More specifically, the user instruction is generated based on the presentation result of the second application. Further, the second application is configured to display the pre-printed paper data and the to-be-printed document data on a preview interface in a separate or superimposed manner for the user to browse, as shown in FIG. 8. In a preferred embodiment, after the second application superimposes the to-be-printed document data and the pre-printed paper data on the preview interface, the user determines, by observing, that the to-be-printed document data is based on the pre-printed paper data. Whether the print position needs to be adjusted, if the document data to be printed needs to be positionally adjusted with respect to the preprinted paper data, the judgment knot of the step S103 If yes, otherwise, the result of the determination in step S103 is negative. Further, if the determination result of the step S103 is affirmative, then proceed to step S104; if the determination result of the step S103 is negative, that is, the document data to be printed is relative to the pre-printed paper data. If no adjustment operation is required, the process proceeds to step S106.

Preferably, in the step S104, if the document data to be printed needs to be adjusted, an adjustment parameter is generated based on the pre-printed paper data and the document data to be printed. Specifically, the adjustment parameter is obtained based on the second application calculation. More specifically, the adjustment parameters include print position adjustment parameters. In a preferred embodiment, the user determines, by the above step S103, that the print position of the document data to be printed on the preprinted paper data needs to be adjusted, and then moves the image to be printed by using an input device such as a mouse or a keyboard or manually touching. After the display window of the document data is in a suitable position, the second application determines the print position adjustment parameter based on the movement distance calculation of the input device. In another preferred embodiment, the second application determines the print position adjustment parameter based on a display window offset value of the document data to be printed after the movement and the document data to be printed before the movement.

Then, step S105 is performed to perform printing based on the document data to be printed and the adjustment parameter. Specifically, the operating system draws a layout of the document data to be printed based on the first application, and sends the layout to the print driver module. More specifically, the print driver module performs a translation process on the document data to be printed based on the adjustment parameter, and then converts it into printable data and sends it to the printer for printing.

Preferably, in the step S106, printable data is generated based on the document data to be printed. It is understood by those skilled in the art that the document data to be printed in this step is determined by the above step S103 to determine that no adjustment operation is required, which means that the document data to be printed can be printed on the appropriate position of the preprinted paper at this time. In accordance with the user's expectation, after the user sends a "print" instruction to the second application, the operating system sends a layout of the data to be printed by the first application to the print driver module, and the print driver module It is to be understood that the technical solution of converting the document data to be printed into printable data according to the present invention is actually a prior art, and is not described herein.

In a variation of the embodiment, the image acquiring device in the step S101 communicates with the printer in an external form, and the user scans the pre-printed paper in advance on the image acquiring device before loading the printer into the printer. Waiting for printing in the paper tray, this can also achieve this step to obtain the pre-play For the purpose of printing paper data, those skilled in the art can also change more embodiments according to actual needs, and details are not described herein.

Further, the operating system further acquires the pre-printed paper data according to a system import manner, where the system import includes local file import, network import, and the like, for example, a local folder is pre-stored in the operating system, including Various types of pre-printed paper data, which may be pre-scanned by the user and stored in the local folder, or may be standard version data provided by the pre-printed paper printer. It is understood by those skilled in the art that the technical solution for acquiring pre-printed paper data based on the image acquiring device in the above step S101 requires pre-installing a device having an image capturing function in the printer, or by contacting a terminal of the printer or the operating system. The communication image acquisition device acquires the pre-printed paper data. In contrast, the technical solution of the present variation allows those printers or terminals that do not have the image acquisition function to acquire the pre-printed paper data as well.

Further, the user can also store the pre-printed paper data acquired in this step in a storage unit for later use, and those skilled in the art understand that for the same type of pre-printed paper data, the user only needs to obtain the pre-printed paper data once. After the data is stored in the storage unit, the acquisition is repeated from the storage unit in the subsequent printing process, thereby eliminating the process of repeatedly acquiring the pre-printed paper data by the operating system before each printing. The earth improves printing efficiency. Preferably, the storage unit comprises a memory, a database, a file, a server, and the like. Preferably, the storage unit is installed in the form of hardware in the printer or terminal, or is separately provided and communicates with the printer or terminal in a wired or wireless manner. Preferably, the storage unit is also software-installable within a printer or operating system, or stored in the cloud and wirelessly communicates with the printer or terminal.

In still another variation of the embodiment, the relevant parameters of the document to be printed, such as paper size, paper length and height, paper type, etc., are assigned to corresponding variables in the DEVMODE structure in step S102, and printed. The driving module may acquire a corresponding variable from the DEVMODE structure based on a function, thereby completing a step of transmitting a relevant parameter of the document to be printed opened by the first application by the DEVMODE structure in the GDI module to the print driver module.

Further, the step of the first application to exchange information with the print driver module and the operating system through the GDIINFO structure in the GDI module mainly includes: the print driver module processes the corresponding variable acquired from the DEVMODE structure Assigned to the GDIINFO structure Corresponding variables are returned to the operating system, and after the first application obtains relevant parameters from the GDIINFO structure on the operating system, the pair of font attributes set in the first application are used to Printing the document data for layout output, determining the maximum number of characters and the maximum number of lines of the document to be printed in the printable area, thereby determining the line feed and page break of the document to be printed.

Further, the interface module further includes a WINE module, which represents a compatibility layer running a Windows application on an operating system compatible with a Portable Operating System Interface (POSIX), and the application of the present invention is achieved by cooperation with the GDI module. The program-printed document data image to be printed can be directly printed on an operating system such as Linux, Mac OSX, BSD, etc., without developing a corresponding application based on different operating systems, and those skilled in the art understand that the application of the present invention Mainly based on the development of the Windows operating system, which cannot be directly run on a processing terminal installed with a non-windows operating system, when the processing terminal installed with the non-windows operating system needs to run the application, the API conversion technology is adopted. The function of non-windows corresponding to Windows is written to call the DLL to run the Windows-based operating system application, so that the application of the present invention can be applied to various operating systems, and the applicable field of the technical solution of the present invention is expanded.

In another variation of the embodiment, the determining step in the step S103 further includes automatically determining, by the computer identification module, that the automatic recognition function of the computer identification module performs some simple observation or recognition operations, for example, Determining whether the preprinted paper data overlaps with the to-be-printed document data; and, for example, acquiring boundary information of the pre-printed paper data and determining whether a portion of the to-be-printed document data exceeds a boundary of the pre-printed paper data range.

Further, the computer identification module may further store a database in advance, including a standard layout template of different types of document data to be printed on the corresponding preprinted paper, when the second application detects that the user is in the first application. After the "print" instruction is issued in the program, the computer identification module is called to first search for a corresponding standard template in the database based on the pre-printed paper data, and then determine, based on the standard template, the document data to be printed on the pre-printed paper data. Whether the location needs to be adjusted. Preferably, the computer automatic identification module is integrated in the second application, and is started to be fed back to the user at a first time when the second application is activated, or the computer automatically recognizes The module is installed in the processing terminal in a third party form, and the second application completes the step S103 by calling the computer automatic identification module The judgment step.

A person skilled in the art understands that, compared with the preview interface automatically generated by the first application in step S102, the preview interface generated by the second application in the step is in an editable state, and the user passes the first application. After the document to be printed is opened and the "print" is clicked, the second application calls the pre-printed paper data acquired in the first application, the document data to be printed, and the two are superimposed and displayed in the form of a window, and the user displays After the user adjusts the position of the to-be-printed document data display window on the preview interface of the second application, the second application calculates the adjustment parameter based on the user operation, and then prints the to-be-printed document data and the adjustment parameter. The drive module performs subsequent adjustment operations.

In still another variation of the embodiment, the adjusting parameter is further determined in the step S104 based on the manner of specifying the alignment reference line. The person skilled in the art understands that the user mouse movement or the keyboard input key control or manual is performed in step S104. The adjustment scheme of the touch mode is preferably applied to the case where the offset direction of the document data to be printed is unified with respect to the preprinted paper data, as described in FIG. 9, at which time the second application sets the document data to be printed with a dotted line. The form frame is defined as an operable frame for the user to drag; but for the case where the offset of the document data to be printed relative to the preprinted paper data is inconsistent as shown in FIG. 10, the second application biases the data of the document to be printed. The data frame with the same direction is set to be the same actionable frame. At this time, although the user can still perform the adjustment operation by dragging and dropping, the data offset direction of the document to be printed is not uniform, and the data of the left part of the data is not right. Quickly completing the offset adjustment of the document data to be printed, the second application is based on the number of preprinted sheets The data area is set to an alignment reference line, and the user only needs to drag the reference line to make the document data to be printed aligned with the alignment reference line, and complete the offset adjustment, as shown in FIG. Show.

Further, the adjustment parameter is further obtained based on a user manual input or confirmation instruction, for example, when the second application superimposes the user to display the to-be-printed document data and the pre-printed paper data, based on the The computer identification module automatically calculates an offset of the document data to be printed relative to the preprinted paper data and presents the recommended offset to the user on the preview interface, and the user can manually input the offset as a reference. The numerical distance of the document data to be printed may also be clicked "OK" to accept the offset suggested by the second application, and the second application may manually input the value or confirm the accepted recommended offset. The print position adjustment parameter is used.

Specifically, first, step S201 is performed to acquire preprinted paper data. Specifically, those skilled in the art may refer to step S101 described in the foregoing embodiment shown in FIG. 3, and details are not described herein.

Before/simultaneous/after performing the step S201, the process proceeds to step S202 to acquire document data to be printed. Specifically, those skilled in the art may refer to step S102 described in the foregoing embodiment shown in FIG. 3, and details are not described herein.

Next, step S203 is executed to determine whether the document data to be printed needs to be adjusted based on a user instruction. Specifically, the user instruction includes a user control instruction and/or indication information. More specifically, the user control instructions include adjustment parameters. Further, the indication information includes information confirming adjustment or not adjusting the document data to be printed. Preferably, the user sends a user instruction to the second application by previewing the print position of the document data to be printed relative to the preprinted paper data on the preview interface to instruct the second application to perform corresponding processing. . In a preferred embodiment, the operating system first determines whether the user instruction includes instruction information for adjusting the document data to be printed. If the user instruction includes adjusting information of the document data to be printed, the determination result of step S203 is Affirmative; otherwise, the judgment result of the step S203 is negative. Further, if the result of the step S203 is affirmative, then proceed to step S204; if the result of the step S203 is negative, that is, the user instruction includes not adjusting the document data to be printed. The information then proceeds to step S206 for execution.

Preferably, in the step S204, if the document data to be printed needs to be adjusted, an adjustment parameter is generated based on the pre-printed paper data and the document data to be printed. Specifically, those skilled in the art may refer to step S104 described in the foregoing embodiment shown in FIG. 3, and details are not described herein.

Next, proceeding to step S205, printing is performed based on the document data to be printed and the adjustment parameter. Specifically, those skilled in the art may refer to step S105 described in the foregoing embodiment shown in FIG. 1, and details are not described herein.

Preferably, in the step S206, printing is performed based on the document data to be printed. A person skilled in the art understands that the document data to be printed in this step is determined by the above step S203, and the operating system directly determines the layout of the document data to be printed by the first application program. a print driver module converted into printable data by the print driver module Then send it to the printer for printing.

In a variation of the embodiment, the print driver module performs the adjustment/pre-simultaneous/after the translation processing of the document data to be printed based on the adjustment parameter in the step S205, and the second application automatically stores the adjustment. The parameter is such that the adjustment parameter can be quickly invoked the next time the same document is printed on the same type of preprinted paper, eliminating the need to repeatedly acquire and adjust the document data to be printed.

In another variation of the embodiment, the step of adjusting the print position of the document data to be printed based on the adjustment parameter in the step S205 may also be implemented by a printer. Specifically, the print driver module bases the first application on The document data to be printed sent by the DEVMODE structure is converted into printable data, and after the printer print position adjustment command is generated based on the adjustment parameter sent by the second application, the printable data and the adjustment command are sent together a printer that adjusts a printer start print position based on the adjustment command when the printer prints, for example, the default print position of the printer is 5 mm, and the adjustment parameter is 2 mm to the left, the printer adjusts The starting print position is 7mm, that is, the printer starts printing documents from 7mm.

It is understood by those skilled in the art that the technical solution described in this embodiment can be considered as a specific application of the embodiment shown in FIG. 3 by converting the adjusted print document data into printable, compared with the embodiment shown in FIG. Data, and based on the adjustment parameter, the translation processing of the document data to be printed or the generation of the print position adjustment command is sent to the printer to adjust the starting print position to realize the adjustment of the print position of the document to be printed, and the change of the user's multiple adjustments and repeated printing is changed. With an operating system, the user experience is greatly optimized.

Further, the first application and the second application are installed independently of each other on the processing terminal, and the second application determines an activation timing by monitoring a process of the first application, specifically The activation opportunity includes a process initiated by the first application based on a user "print" instruction. Further, the second application may be embedded in the program code of the first application by using a patch, and the second application is invoked when the first application receives the “print” instruction of the user. The program is further processed.

In a common variation of the embodiment shown in FIG. 3 and the embodiment, the step S104 in the embodiment shown in FIG. 3 or the step S204 in the embodiment further includes the step “to The print paper data is stored in accordance with the adjustment parameter. Specifically, the preprinted paper data and the adjustment parameter are pre-stored in a storage device including a background thread, a flash drive, a flash, and a print. a driving module, a cloud storage device, etc. Further, the operating system directly acquires the pre-printed paper information from the storage device after receiving a print instruction of the user, and based on the adjustment corresponding to the pre-printed paper data The parameter adjusts the position of the document data to be printed, so that the document data to be printed that has been adjusted based on the stored adjustment parameters is displayed on the preview interface displayed to the user. In many cases, such adjustment can satisfy the user's expectation, and the user only The printing operation needs to be sent to the second application to complete the printing operation. Those skilled in the art understand that for a fixed format of preprinted paper data, the adjustment parameters are likely to be determined, and when the user needs to be multiple times When you print data on pre-printed paper of the same format, you don’t have to recalculate each time Adjust parameters, pre-adjustment of the position of the print data in this document to be printed by calling adjustment parameter storage, improve work efficiency.

Further, the second application acquires an adjustment parameter corresponding to the pre-printed paper data while/after acquiring the pre-printed paper data from the storage device, and pairs the to-be-printed based on the adjustment parameter The document data is pre-adjusted, and then the pre-adjusted document data to be printed and the superimposed effect of the pre-printed paper data are displayed on the preview interface. If the user feels that the preview result is as expected, the "print" option is directly clicked. Entering the printing step, the adjustment parameter corresponding to the pre-printed paper data in the storage device is the adjustment parameter of the current printing; or, if the user feels that the position of the pre-adjusted document data to be printed relative to the pre-printed paper data is not The document data to be printed may be further adjusted on the preview interface until the print position of the document data to be printed meets the user's expectation, and the user manually adjusts the generated adjustment parameter. Adjust the parameters for the print position of this print.

Further, even if the user directly selects the print without entering the print position adjustment interface at the time of the current printing, the second application may acquire the adjustment parameter corresponding to the pre-printed paper data from the storage device, and issue the adjustment parameter. And a print driver module, wherein the print driver module performs a translation process on the document to be printed based on the adjustment parameter, or generates a print position adjustment command based on the adjustment parameter and sends the print position adjustment command to the printer to adjust the initial print position.

Further, the second application superimposes the pre-printed paper data and the to-be-printed document data on the preview interface only when the adjustment parameter corresponding to the pre-printed paper data cannot be acquired from the storage device The user shows that if the second application is available from the storage device The adjustment parameter corresponding to the pre-printed paper data is directly sent to the print driver module for printing.

FIG. 5 illustrates a flow chart for determining whether the document data to be printed needs to be adjusted according to an embodiment of the present invention, which is determined based on preprinted paper data and document data to be printed. Specifically, step S1031 is first performed to superimpose and display the preprinted paper data and the document data to be printed in the form of a window. More specifically, the pre-printed paper data and the document data to be printed are sequentially superimposed on a preview interface, and the preview interface is generated based on the second application. In a preferred embodiment, after receiving the "print" instruction issued by the user in the first application, the second application first calls the interface function StretchBlt() in the operating system application programming interface API to print the to-be-printed The document data is displayed in the form of a window on the pop-up preview interface. As shown in FIG. 7, when the user clicks the "print position adjustment" option on the preview interface, the second application is further based on the StretchBlt(). The function displays the preprinted paper data in the operating system in the form of a window on the preview interface as well.

Further, the second application displays the window layer transparency by adjusting the document data to be printed and the preprinted paper data to ensure that the lower layer data image is not subjected to the upper layer data when the document data to be printed and the preprinted paper data are superimposed and displayed. Covered by the image, as shown in FIG. 8, the second application translucents the window containing the pre-printed paper data by adjusting the transparency of the window attribute containing the pre-printed paper data on the preview interface. Thereby, the preprinted paper data and the document data to be printed can be superimposedly displayed on the preview interface without interference.

Then, step S1032 is executed to receive a user instruction to determine whether the document data to be printed needs to be adjusted. Specifically, the user instruction includes a control instruction for the user to adjust the document data to be printed. More specifically, the control instruction includes instruction information for the user to move the document data to be printed. Further, the second application generates the adjustment parameter based on the control instruction. In a preferred embodiment, the second application considers that the user moves the data of the document to be printed by sending a control instruction thereto, for example, the user moves by the mouse drag or the keyboard direction key on the preview interface. The method of moving the document data to be printed to a desired position and clicking the "print" option, the second application uses the position offset of the moved document data to be printed relative to the original document data to be printed as the Adjustment parameters.

In a variant of the embodiment, the previewing step of the sequential superimposed display in the step S1031 may be replaced by displaying the pre-printed paper data and the document data to be printed simultaneously on the preview interface, ie After the user clicks the "print" option in the first application, the second application simultaneously displays the to-be-printed document data and the display window corresponding to the pre-printed paper data in the pop-up preview interface, It is understood by the person that, compared with the technical solution described in the above step S1031, the technical solution of the present variation preferably defaults to previewing the print position of the document data to be printed on the pre-printed paper data for the user. It saves the steps of additional confirmation and is beneficial to the user experience.

In still another variation of the embodiment, the step S1031 and the step S1032 further include the step of “superimposing and displaying the pre-printed paper data and the to-be-printed document data in a window form in a terminal, wherein The terminal is associated with the printer." For example, the operating system may superimpose and display the pre-printed paper data and the to-be-printed document data in a window form on any terminal in the wireless local area network with the printer, as understood by those skilled in the art, Compared with the technical solution in the foregoing step S1031, the technical solution in the present variation allows the superimposed display result to be no longer limited to being browsed only by users currently located in the periphery of the printer, and the technical solutions according to the present variation, those Users who are not currently around the printer can also remotely control printer printing operations. For example, if the assistant is operating the printer and needs the boss to confirm whether it can be officially printed, the assistant can superimpose the document data to be printed with the preprinted paper data display window through the printer. The displayed effect is transmitted wirelessly to the boss's mobile phone, and the owner confirms whether to print on the mobile phone. Further, the printer associated with the terminal described in this variation may also be replaced with a processing terminal where the print driver module is located, which may also implement a printing operation based on remote user instructions.

Further, the terminal is associated with the printer in a wired/wireless manner. The wired manner includes associating the terminal with the printer based on an optical fiber, a cable, a data line, or the like; the wireless manner includes a wireless local area network, a Bluetooth, an infrared, a ZigBee, a wireless Internet, etc., and the terminal is The printer is associated. Further, the terminal includes a mobile terminal and a fixed terminal, wherein the mobile terminal includes a mobile phone, an IPAD, a notebook computer, and the like; the fixed terminal includes a computer, a processing terminal having a display function, and the like.

In another variation of the embodiment, the receiving step in the step S1032 further includes: “receiving the user to adjust the indication information of the document data to be printed, the indication information determining that the document data to be printed needs to be adjusted” For example, the user observes the document to be printed on the preview interface by observing And superimposing the data and the pre-printed paper data, determining that the document data to be printed needs to be adjusted, and clicking the “adjust” option on the operation interface to send the indication information for confirming the adjustment to the second application, the second After receiving the indication information, the application determines, based on the computer identification module, an offset of the document data to be printed relative to the pre-printed paper data and generates an adjustment parameter.

Further, the second application invokes the computer identification module to adjust the data of the document to be printed based on the user indication information, and automatically generates an adjustment parameter, which is understood by those skilled in the art, when the user is in an outgoing state or through a mobile phone or the like. When the screen device previews the display window, the document data to be printed cannot be moved to the position expected by the user by clicking drag and drop or keyboard input due to inconvenience, etc., at this time, the user only needs to click the “adjust” option to adjust the action. After the second application is completed, the user can easily and conveniently know whether the adjustment result meets the user's expectation by previewing the superimposed effect of the updated document data to be printed and the pre-printed paper data after previewing the second application. If the adjustment result meets the user's expectation, the adjustment parameters generated during the adjustment will be sent to the print driver module; if the adjustment result does not meet the user's expectations, the user can click the “Adjust” option again to re-adjust, or click and drag. Way to send control commands directly to the application The control command includes a user moves the document data to be printed adjustment parameters generated on the preview screen.

It is understood by those skilled in the art that the technical solution that the print result of the document data to be printed and the preprinted paper data is superimposed and displayed in a window form before the official printing to the user preview is enabled in the embodiment, so that the user can intuitively understand the print before confirming the print. Whether the result conforms to the user's expectation, the display mode of the semi-transparent display window of the pre-printed paper data is advantageous for the user to observe the position deviation of the pre-printed paper data and the document data to be printed, which is a technical solution not adopted by the prior art. It can effectively reduce the number of repeated operations of the user print-adjust the print position. Further, the second application may also display the document data to be printed in the form of a semi-transparent window, and display the pre-printed paper data in the form of a normal window, which may also be generated by a user-defined selection, which is not Affects the technical content of the present invention.

FIG. 6 illustrates a flow chart for determining whether the document data to be printed needs to be adjusted according to still another embodiment of the present invention, which is determined based on preprinted paper data and document data to be printed. Specifically, first step S1033 is performed to determine whether the document data to be printed is related to the pre-print The displayable content of the printed paper data overlaps. More specifically, the overlapping effects include text and text, images and images, or overlapping of text and images. In a preferred embodiment, the computer identification module determines whether the two are overlapped based on the pre-printed paper data displayable content and the respective positional parameters of the to-be-printed document data, as shown in FIG. 9, for example, the pre-printing The paper data displayable line is located at a distance of 7 cm from the left of the preprinted paper to 18 cm from the left and 20 cm from the upper edge of the preprinted paper, and the computer identification module determines the to be printed based on the position parameter. Whether there is display content in the same position in the document data, if the document data to be printed overlaps with the displayable content of the preprinted paper data, the determination result of the step S1033 is affirmative; otherwise, the step is The judgment result of S1033 is negative. Further, if the result of the determination in step S1033 is affirmative, then proceed to step S1034; if the result of the determination in step S1033 is negative, that is, the document data to be printed and the data of the pre-printed paper If the displayable contents do not overlap, the process proceeds to step S1035.

Preferably, in the step S1034, the computer identification module determines an adjustment parameter based on an overlapping area of the document data to be printed and the pre-printed paper data, so that the two are no longer overlapped. In a preferred embodiment, the computer identification module applies the adjustment parameter as a whole to all data of the document data to be printed, for example, after determining the third line of the document data to be printed and the pre-printed paper data. The fourth line of the displayable content overlaps by 3 cm, and the computer recognition module shifts the document data to be printed as a whole by 3 cm. Preferably, the computer identification module repeatedly performs the step S1033 once after the analog adjustment of the document data to be printed based on the adjustment parameter, and determines whether the adjusted document data to be printed is related to the pre-printing. The displayable contents of the paper document overlap, and if they overlap, the step S1034 is continued to adjust the document data to be printed until the printable document data and the preprinted paper data displayable content no longer overlap.

Preferably, in the step S1035, the computer identification module further determines whether part of the document data to be printed is outside the preprinted paper data area, for example, in the legend shown in FIG. 10, although The document data to be printed is not overlapped with the displayable content of the preprinted paper data, but a part of the document data to be printed is beyond the data area of the preprinted paper data, so adjustment is still needed, and the step S1035 is performed. The judgment result is affirmative; otherwise, the judgment result of the step S1035 is negative. Further, if the result of the determination in step S1035 is affirmative, then proceed to step S1036; if the judgment of step S1035 is If it is negative, that is, the document data to be printed is not overlapped with the preprintable paper data displayable content, and no part of the data area beyond the preprinted paper data is passed, the process proceeds to step S1037.

Preferably, in the step S1036, the computer identification module determines that the document data to be printed needs to be adjusted. Correspondingly, the application acquires an offset distance and an offset direction of the document data to be printed with respect to the preprinted paper data area, and preferably reverses the offset distance and the offset direction As the adjustment parameter.

Preferably, in the step S1037, the computer identification module determines that the document data to be printed does not need to be adjusted. Correspondingly, the print driver module converts the to-be-printed document data into printable data and sends it directly to the printer for printing.

Further, in the step S1034, the computer identification module presets a default adjustment direction, and if the overlapped area of the adjusted document data to be printed and the preprinted paper data display content does not fall, then Performing a second adjustment to the direction of the double adjustment parameter in the opposite direction of the default adjustment direction, and those skilled in the art understand that, for the technical solution of determining the adjustment based on the overlap determination result in step S1034, the overlapping area is The adjustment includes the adjustment feasibility schemes of the upper, lower, left and right directions, and the adjustment results of the four adjustment feasibility schemes need to be judged, and the optimal adjustment scheme is selected as the adjustment parameter. In a preferred embodiment, the computer identification module sets a default adjustment direction based on the document data to be printed and the paper boundary distance, which preferably moves the document data to be printed to a direction in which the boundary distance is larger.

Further, the adjusted document data to be printed is still displayed on the preview interface in superimposed manner with the pre-printed paper data, and the user determines whether the user's expectation is met, and if the user confirms that the content meets the expectation, click the “print” button. The second application sends the adjustment parameter to the print driver module; if the user is still not satisfied with the adjustment result, click the “Adjust” button, and the computer recognition module adjusts the document data to be printed again. In a non-preferred example, the user may also indicate that the second application does not feed back the adjusted document data to be printed through the previous setting, but directly sends the print operation to the print driver module to save the user waiting time.

Judge. In this embodiment, it is determined by the layer overlay technology whether a layer formed by the document data to be printed and the preprinted paper data respectively covers a non-blank layer region of the other party, and the person skilled in the art understands that the The printed document data and the pre-printed paper data are finally converted into an image form and displayed on the preview interface. Compared with the technical solution described in the above step S1033, the technical solution of the present variation can be realized by layer comparison. Accurate interpretation of overlapping judgments reduces the false positive rate and improves the accuracy of automatic recognition of computer recognition modules.

In another variation of the embodiment, the step S1035 and the step S1036 may be omitted, and the computer identification module determines that the to-be-printed document data does not overlap with the displayable content of the pre-printed paper data. After the data of the document to be printed does not need to be directly determined, the print driver module can directly convert the data of the document to be printed into printable data and send it to the printer for printing.

It is understood by those skilled in the art that, compared with the embodiment shown in FIG. 5, the technical solution in this embodiment preferably determines that the document data to be printed is on the pre-printed paper data by means of automatic recognition by the computer identification module.

Further, those skilled in the art may also use the technical solution described in the foregoing embodiment shown in FIG. 5 in combination with the technical solution described in this embodiment. For example, after the computer identification module automatically adjusts the printed document data, And displaying the to-be-printed document data and the pre-printed paper data on the preview interface. If the user thinks that the current automatic adjustment result does not meet the expected result, directly moving the to-be-printed document data on the preview interface to generate an adjustment parameter. Optimize the print results so that the print results are as high as possible.

It is understood by those skilled in the art that in a common variation of the embodiment shown in FIG. 3 to FIG. 6, the second application further allows the user to perform optimization processing on the document data to be printed, such as As shown in FIG. 12, in addition to the print position adjustment operation, the user can adjust the contrast, brightness, and the like of the document data to be printed, or perform image processing such as cropping, rotation, and the like on the document data to be printed. Further, when the user clicks an optimization processing option such as contrast adjustment, brightness adjustment, etc., the second application does not call the pre-printed paper data, and the preview interface preferably displays the image data to be printed after the image processing, only When the user clicks the "print position adjustment" option, the second application will retrieve the pre-printed paper data and superimpose it on the preview interface for the user to browse. This design is more user-friendly and can be given to the user. Provide a good user experience.
