[0050] The embodiment of the application also provides a data association method, applied to the above printing device.
[0051] Referring to Figure 3 , an embodiment of the data association method of the present application is proposed. In this embodiment, the data association method includes:
[0052] Step S10, obtaining target data to be printed in an electronic document and page number information corresponding to the target data;
[0053] The electronic document is a document specified by the user to print the content therein, and the target data is the content specified by the user to print in the electronic document. The target data can include data of several pages in the electronic document. It should be noted that the page number information is the unique page number of the target data in the electronic document, which is used to distinguish and locate the data of different pages in the electronic document, and is not the page number recorded by the page number function inserted in the electronic document.
[0054] Optionally, the user specifies the electronic document to be printed and the target data to be printed on the client, and the printing device obtains the target data and the page number information corresponding to the target data from the client. In addition, a setting switch corresponding to the data association method can be configured on the printing device, which is used to distinguish between printing on ordinary paper or printing on dot-matrix paper.
[0055] In step S20, a first graphical code of the target dot-matrix paper is generated, and the first graphical code is associated with the page number information to form an association relationship.
[0056] In this embodiment, the first graphical code is a one-dimensional code. When the printing device generates the first graphical code, a random non-repeating numerical code of a preset number of digits is generated, and a one-dimensional code corresponding to the numerical code is generated. It should be noted that in this embodiment, the target data is one page of data in the electronic document. In practice, the target data can be a plurality of pages of data in the electronic document, and the target dot-matrix paper includes a corresponding number of papers (single-sided printing) and a corresponding number of first graphical codes are generated for each target dot-matrix paper.
[0057] In other embodiments, the first graphical code can also be other types of graphical codes.
[0058] Optionally, the printing device generates the first graphical code corresponding to the target dot-matrix paper, and associates the first graphical code with the page number information. In addition, the association relationship between the first graphical code and the page number information can be sent to the server for storage, so that the user can determine the association relationship through the server when using the target dot-matrix paper.
[0059] In step S30, the graphical identifier corresponding to the first graphical code and the target data are printed on the target dot-matrix paper, so that the target data is associated with the first written data in the area outside the graphical identifier on the target dot-matrix paper based on the association relationship.
[0060] The graphical identifier is an identifier corresponding to the first graphical code, which is a graphical identifier of the one-dimensional code in this embodiment, or a graphical identifier generated according to the first graphical code. The first written data is written data of the dot-matrix pen in the area outside the graphical identifier on the target dot-matrix paper.
[0061] Optionally, the printing device prints the graphical identifier corresponding to the first graphical code and the target data on the target dot-matrix paper. When the user uses the target dot-matrix paper, the user can scan the graphical identifier thereon to identify the corresponding first graphical code, and the client determines the corresponding page in the electronic document according to the association relationship between the first graphical code and the page number information, so as to associate the first written data in the area outside the graphical identifier on the target dot-matrix paper with the target data. At this time, the first written data written by the user on the target dot-matrix paper can be synchronized to the corresponding page of the client electronic document.
[0062] The data association method provided by the embodiment of the present application comprises the following steps: obtaining target data to be printed in an electronic document and page number information corresponding to the target data; generating a first graphic code of a target dot matrix paper, associating the first graphic code with the page number information to form an association relationship, and establishing an indirect association relationship between the target data and the first graphic code; and then printing a graphic mark corresponding to the first graphic code and the target data to the target dot matrix paper, so as to associate the target data with first writing data in a region other than the graphic mark on the target dot matrix paper based on the association relationship. Compared with the association data between the page number of the dot matrix paper and the page number of the electronic document which is additionally input after the target data is printed to the target dot matrix paper, the graphic mark corresponding to the first graphic code is printed to the target dot matrix paper at the same time when printing in the present application, and the user can associate the first writing data and the target data by using the graphic mark when using the target dot matrix paper, which is equivalent to realizing the association between the page number corresponding to the target dot matrix paper and the page number corresponding to the target data, and the operation complexity of the user in associating the offline dot matrix paper writing content and the online electronic document corresponding data is reduced, thereby improving the user experience.
[0063] Further, in the embodiment, the step of printing the graphic mark corresponding to the first graphic code and the target data to the target dot matrix paper comprises:
[0064] printing the graphic mark corresponding to the first graphic code to a first preset region of the target dot matrix paper, and printing the target data to a second preset region of the target dot matrix paper;
[0065] wherein the first preset region and the second preset region are both dot matrix code regions on the target dot matrix paper, and the first preset region and the second preset region do not overlap.
[0066] In the target dot matrix paper, the first preset region is predefined for printing the graphic mark corresponding to the first graphic code, and the second preset region is predefined for printing the target data, and the first preset region and the second preset region do not overlap, so as to prevent the conflict of the printed regions and affect the printing effect of the graphic mark or the target data.
[0067] In addition, the user can select the position of the first preset region before printing, for example, the upper left corner or the upper right corner of the paper, and the region of the target dot matrix paper other than the first preset region is the second preset region.
[0068] Further, the first preset region and the second preset region are both dot matrix code regions on the dot matrix paper, that is, the regions on which the dot matrix pen can recognize the writing data when writing. Based on this, the user can directly use the dot matrix pen to complete the scanning of the graphic mark, further reducing the operation complexity.
[0069] Further, based on the above embodiment, another embodiment of the data association method is provided. In the embodiment, referring to Figure 4 The step of printing the target data and the graphic mark corresponding to the first graphic code to the target dot matrix paper comprises:
[0070] In step S31, the first graphic code is subjected to inverse color processing to obtain the graphic mark.
[0071] In the embodiment, the first graphic code is a one-dimensional code, and the graphic mark obtained by subjecting the one-dimensional code to inverse color processing is the one-dimensional code after inverse color processing.
[0072] In step S32, the graphic mark and the target data are printed to the target dot matrix paper.
[0073] Optionally, the one-dimensional code after inverse color processing and the target data are printed to the target dot matrix paper.
[0074] The one-dimensional code after inverse color processing cannot be directly scanned by a scanning device such as a mobile terminal, thereby preventing the first graphic code from being mis-scanned, and when the user slides the dot matrix pen on the graphic mark, the handwriting falling on the blank area of the graphic mark corresponds to the original black area of the one-dimensional code due to the inverse color processing, thereby saving the step of scanning and identifying the first graphic code by using the dot matrix pen and further reducing the operation complexity.
[0075] The embodiment of the application further provides a data association method applied to the server.
[0076] Referring to Figure 5 Another embodiment of the data association method is provided. In the embodiment, the data association method comprises:
[0077] In step S40, second writing data of the dot matrix pen on the graphic mark in the target dot matrix paper is obtained.
[0078] The second writing data is writing data of the dot matrix pen in the area of the graphic mark in the target dot matrix paper; when the user writes in the area of the graphic mark in the target dot matrix paper by using the dot matrix pen, the second writing data corresponding to the handwriting can be identified and transmitted to the server due to the dot matrix code in the area.
[0079] In step S50, the first graphic code corresponding to the graphic mark is determined according to the second writing data, and page information having an association relationship with the first graphic code is determined.
[0080] Optionally, the server can determine the first graphic code corresponding to the graphic mark according to the second writing data, and determine the page information having an association relationship with the first graphic code by recording the association relationship between the first graphic code and the page information in the server.
[0081] Step S60, determining target data corresponding to the page number information in the electronic document according to the page number information;
[0082] Optionally, the corresponding electronic document and target data can be determined according to the page number information, so as to determine the target data corresponding to the printed content on the target dot-matrix paper used by the user at this time.
[0083] Step S70, associating the first writing data in the area outside the graphic mark on the target dot-matrix paper with the target data.
[0084] Optionally, the first writing data in the area outside the graphic mark on the target dot-matrix paper (equivalent to the writing data of the user on the target data printed area of the target dot-matrix paper) is associated with the target data in the electronic document, so as to realize synchronization of the writing data.
[0085] In addition, the first writing data and the page number information can be sent to the client, so that the client synchronously displays the target data corresponding to the printed content on the target dot-matrix paper, and further displays the first writing data on the displayed target data.
[0086] According to the second writing data written by the user on the graphic mark in the target dot-matrix paper, and the association relationship between the first graphic code and the page number information recorded in the server, the target data corresponding to the printed content on the target dot-matrix paper is determined according to the graphic mark of the dot-matrix paper. For the user, when using the dot-matrix paper, the dot-matrix pen is used to slide on the graphic mark area, so as to establish the association with the corresponding target data, to perform subsequent writing data synchronization, reduce the operation complexity of the user, and improve the user experience.
[0087] Further, in the embodiment, the step of determining the first graphic code corresponding to the graphic mark according to the second writing data comprises:
[0088] According to the trajectory information of the dot-matrix pen corresponding to the second writing data and the graphic mark, a plurality of sub-trajectories in the first direction are determined, and the plurality of sub-trajectories fall in the blank sub-area in the area inside the graphic mark;
[0089] The plurality of sub-trajectories are extended along the second direction by a second preset length, and the first graphic code corresponding to the graphic mark is obtained.
[0090] The trajectory information is information representing the moving trajectory of the dot-matrix pen. Optionally, the first graphic code is a one-dimensional code, the area corresponding to the graphic mark is a rectangle according to the graphic shape of the one-dimensional code, the first direction is determined by the long side of the rectangle, the second direction is determined by the width of the rectangle, and the second preset length is the length of the width of the rectangle.
[0091] For the first direction and the second direction, exemplary, establish the xy coordinate axis with one of the right angles of the rectangle, let the long side of the rectangle coincide with the x axis, and the wide side coincide with the y axis, then the first direction can be the positive direction or the negative direction of the x axis, and the second direction can be the positive direction or the negative direction of the y axis.
[0092] Based on the above embodiment, the graphic mark is a one-dimensional code after the inverse color processing, and therefore the blank sub-region in the area of the graphic mark corresponds to the black region of the one-dimensional code. Exemplary, referring to Figure 6 , Figure 6 The first graphic code, the graphic mark obtained after the inverse color processing, the plurality of sub-tracks in the first direction, and the graphic illustration example of the plurality of sub-tracks extending along the second direction are listed from top to bottom in the figure. According to the track information corresponding to the second writing data, the plurality of sub-tracks in the first direction falling in the blank sub-region are determined, which is equivalent to determining the plurality of tracks of the one-dimensional code in the first direction; further, extending the plurality of sub-tracks along the second direction by the second preset length, the graphic of the one-dimensional code is restored, which is equivalent to determining the corresponding first graphic code.
[0093] By determining the plurality of sub-tracks of the second writing data in the first direction and extending along the second direction, the restoration of the first graphic code according to the second writing data is realized, the corresponding first graphic code is identified by sliding the dot matrix pen on the graphic mark, and therefore the associated target data is further determined, thereby reducing the operation complexity of the user.
[0094] Further, based on the above embodiment, another embodiment of the data association method of the application is proposed. In this embodiment, referring to Figure 7 , the step of obtaining the second writing data of the dot matrix pen on the graphic mark in the target dot matrix paper includes:
[0095] Step S41, obtaining the third writing data of the dot matrix pen on the target dot matrix paper;
[0096] The third writing data is the writing data of the dot matrix pen on the target dot matrix paper, and the writing region of which has not been determined.
[0097] Step S42, determining the writing region of the third writing data on the target dot matrix paper;
[0098] Based on the technical features of the dot matrix code paving on the dot matrix paper, when the dot matrix pen writes on the dot matrix paper, the current position of the dot matrix pen on the dot matrix paper can be identified according to the dot matrix code slid, and therefore the writing data can be displayed at the corresponding position of the target data. In this embodiment, after obtaining the third writing data, the writing region of the third writing data on the target dot matrix paper is determined first.
[0099] Step S43, when the writing area is the first preset area on the target dot paper, determining that the third writing data is the second writing data.
[0100] Optionally, when it is determined that the writing area of the third writing data is the first preset area on the target dot paper, it can be determined that the third writing data is the data written by the dot pen on the graphic mark, which can be used to determine the first graphic code, i.e., to determine that the third writing data is the second writing data.
[0101] By determining whether the writing area of the third writing data is the first preset area on which the graphic mark is located, it can be determined whether the third writing data is the writing data written on the graphic mark; when the user uses the self-defined dot paper, the server can intelligently determine the writing area and execute the subsequent steps of determining the first graphic code and associating the target data by only using the dot pen to write on the graphic mark, thereby reducing the operation complexity of the user.
[0102] Further, in the embodiment, after the step of obtaining the second writing data of the dot pen on the graphic mark on the target dot paper, the method further comprises:
[0103] determining the trajectory information of the dot pen according to the second writing data;
[0104] determining the trajectory length of the trajectory information in the first direction;
[0105] when the trajectory length is greater than or equal to the first preset length, executing the step of determining the first graphic code corresponding to the graphic mark according to the second writing data.
[0106] The trajectory information is information representing the moving trajectory of the dot pen. Optionally, the first graphic code is a one-dimensional code, the first preset area on which the graphic mark is located is a rectangle according to the graphic shape of the one-dimensional code, and the first preset length is the length of the long side of the rectangle. The first direction is determined according to the long side of the rectangle.
[0107] For the first direction, for example, an xy coordinate axis is established according to one of the right angles of the rectangle, and the long side of the rectangle is coincided with the x axis. Therefore, the first direction can be the positive direction or the negative direction of the x axis.
[0108] Further, the trajectory length of the trajectory information in the first direction is determined, and when the trajectory length is greater than or equal to the first preset length, it is equivalent to that the second writing data crosses the entire first preset area in the first direction, i.e., crosses the entire graphic mark in the first direction. At this time, the complete first graphic code can be determined according to the second writing data.
[0109] By determining the track length of the second writing data track information in the first direction, whether the second writing data completely passes through the graphic mark can be determined according to the track length, and the step of determining the first graphic code is executed when it is determined that the second writing data completely passes through the graphic mark, so that the first graphic code is intelligently determined when the dot matrix pen passes through the graphic mark, and the operation complexity of the user is reduced.
[0110] In addition, the embodiment of the present application also provides a storage medium, wherein the storage medium stores a data association program, and the data association program is executed by a processor to realize the related steps of any one of the above data association methods.
