Description

  The present invention relates to a printing method for printing a document provided using a web browser on the Internet, and more particularly to a technique for printing a document such as a table whose line height is not fixed on a plurality of printing sheets. .

Conventionally, various texts have been created and published on the web by web applications using web browsers such as Internet Explorer and Netscape, and users who have viewed the text are required to the extent permitted by the application. It is possible to print out and use appropriate sentences.
(For example, refer to Patent Document 1).
JP 11-338666 A

By the way, among the texts provided on the Web as described above, when trying to print a document such as a table without dividing one line in the middle of the page, the paper size to be printed is limited in advance and matched accordingly. Therefore, it is necessary to take a layout in which the height of one row is fixed so that the rows are not divided.
In this case, in a Web application in which the user can arbitrarily modify data, the input information must be restricted so that the height of the fixed line is not exceeded, and the user can freely create a document. It becomes an obstacle to doing.
In addition, in the case of image information such as figures, it is necessary to reduce it to fit the line size, so there is a possibility that the expressive power when displaying the document may be reduced. From this point also, the user can create the document freely It becomes an obstacle to doing.
Therefore, in order to ease restrictions on document creation for users, it may be possible to freely change the height of one line for documents such as figures and tables. When printing, one image is printed over two pages, and one line in a document may be divided into two pages, so it is not suitable for a Web application for printing purposes. There are challenges.

  Therefore, the present invention can prevent the image of one line from being divided into two pages for a document such as a table whose height between lines is not fixed, and can provide a user with a free document creation environment on the Web. An object is to provide a printing method.

  In order to achieve the above object, the printing method of the present invention includes a detection step of detecting a user output instruction for document data acquired from a Web browser, and the document data when the output instruction is detected by the detection step. An output step of outputting a predetermined unit line to an output memory, and a page size acquisition step of acquiring the page size of the Web browser using data of an instruction description file or an embedded instruction in a document operating on the Web browser A height calculation step of calculating the height in the row direction of the document data in one page output to the output memory by the output step using the data of the instruction description file or the embedded instruction in the document; Calculated by the page size acquired in the page size acquisition step and the height calculation step Based on the comparison step for comparing the height and the comparison result of the comparison step, when the height of the output document data exceeds the page size, before the predetermined line at the end of the document data output to the output memory And a page break control step for inserting page break information.

  According to the printing method of the present invention, in an application using a web browser such as Internet Explorer or Netscape, page feed does not occur in the middle of a line even for a document such as a table whose line spacing height is not fixed. , It has the effect of printing nicely.

FIG. 1 is a block diagram showing the configuration of a network system that implements a printing method according to the present invention.
In the system of this example, in an application using a web browser such as Internet Explorer or Netscape, even if the document is a table such as a table whose line spacing is not fixed, page feed does not occur in the middle of one line at the time of printing. It is designed to print nicely.
As shown in FIG. 1, a network client terminal 30 and a printing apparatus 40 are connected to a Web server 10 that supplies document information and the like through a network 20 such as a LAN or a WAN.

The network client terminal 30 is an information processing terminal such as a personal computer or a workstation. As a functional module using hardware and software, a Web browser 31, a display function unit 32, an input function unit 33, a print function unit 34, a network interface 35, and the like. It is equipped with.
Of these, the Web browser 31 performs a search of a homepage on the Internet. The display function unit 32 controls the display device 50 as a peripheral device. The input function unit 33 controls the input device 60 such as a keyboard and a mouse (pointing device). The print function unit 34 also controls a printing device 70 as a peripheral device. Further, the network interface 35 controls communication with the network 20.
The printing apparatus 40 has a network interface 41 inside, and has a function of printing out print data supplied from a server or the like through the network.

In this example, the operation is mainly performed when a process for specifying and printing the printing device 40 or 70 is selected in a state in which the text acquired using the web browser 31 on the network client terminal 30 is displayed on the display screen. Explained.
FIG. 2 is a block diagram showing a functional configuration for realizing the printing method of the present invention in the network client terminal shown in FIG. 1, which is mainly realized by a control program.
In the figure, the detection processing module 100 executes a detection step of detecting a user output instruction for document data acquired from the Web browser 31. Further, when an output instruction is detected in the detection step, the output processing module 110 stores the document data in an output memory (in this example, a display memory and a print memory) by a predetermined unit line (in this example, one line). Execute the output step to output.

Further, the page size acquisition processing module 120 is an element object (for example, ClientWidth, ClientHeight or InnerWidth, InnerHeight) in an instruction description file or an embedded instruction (in this example, a Java (registered trademark) script) operating on a Web browser. A page size acquisition step of dynamically acquiring the page size of the Web browser is executed using.
In addition, the calculation processing module 130 uses the element object (for example, InnerHTML) or the style sheet (for example, style.display) of the embedded instruction in the instruction description file or in the document to output one page to the output memory by the output step. A height calculation step for calculating the height of the document data in the row direction is executed.
Further, the comparison processing module 140 executes a comparison step that compares the page size acquired in the page size acquisition step with the height calculated in the height calculation step.
Further, the page break control processing module 150, based on the comparison result of the comparison step, before the predetermined line at the end of the document data output to the output memory when the height of the output document data exceeds the page size. A page break control step for inserting page break information is executed.

  With such a processing module configuration, the network client terminal 30 of this example receives the Java (registered trademark) script supplied from the Web server 10 and receives ClientWidth, ClientHeight, which are one of the element objects of the Java (registered trademark) script. Alternatively, while dynamically acquiring the Web browser display size by InnerWidth and InnerHeight, the rows are displayed sequentially on the Web browser display screen using the inner HTML of the element object or style.display which is the style sheet. Processes to prevent line breaks by entering page break information just before the display screen is full. Then, the processed document is printed in the same manner as described above to prevent the division of the line of the printed document.

FIG. 3 is a flowchart showing a specific flow of such processing.
In this example, it is assumed that a Java (registered trademark) script program for executing processing as illustrated is embedded in a document provided from a Web server.
First, in step S1, the page size of the display screen of the web browser (the height in the row direction of one page) is determined. In this case, a method of dynamically acquiring using the element objects (for example, ClientWidth, ClientHeight or InnerWidth, InnerHeight) in the above-described Java (registered trademark) script is also possible, but the page size is acquired in advance. It is also possible to read the information from the memory and determine it. This is the case, for example, when displaying or printing a file temporarily stored in the terminal.
If insertion of header information is instructed in step S2, header information set in advance at the head of the page is inserted. Thereafter, in step S3, it is determined whether or not the display of all the line data has been completed. If the display of all the line data has been completed, the insertion of footer information is instructed. The footer information set in advance is inserted (step S11), and the process is terminated.

If the display of all the line data is not completed, the line data of the table document is displayed on the screen line by line (step S4), and the height of the display area of the line data after display is measured (step S5). ). Here, since it is necessary to dynamically change the HTML document, the document data to be displayed is formatted each time in the process of step S3 and is displayed on the browser by an element object of Java (registered trademark): innerHTML. Instead of InnerHTML, a program that uses a style sheet: style.display and adjusts whether or not display is possible may be used.
Further, the display object: ClientHeight is used for the height measurement of the display area of the row data in step S5. However, ClientHeight is used for Internet Explorer, but innerHeight is used for Mozilla browsers such as Netscape and FireFox.

In step S6, the height of the line data display area is compared with the height of the browser display screen. If the height of the line data display area is within the browser display screen, the process returns to step S3 to return to the next. The line data is displayed. If not, the line data does not fit on the page, so the line data is turned to the next page (step S7), and footer information, page break information, and header information are sequentially embedded (steps S8, S9, and S10). Then, the process returns to step S3 and shifts to the display of the next page. Here, the document data that is displayed first is the line data that is turned to the next page in step S7.
In this way, in this example, text data is displayed line by line, and it is determined whether it can fit in the area of one page. Therefore, even if the line spacing is variable, one line is divided and spread over two pages. It can be prevented from being displayed.
Here, the case where the display and output of the document data acquired from the Web server has been described. However, even when the document data subjected to such a page break process is output by the printing apparatus, the line break information is set to one line. It is possible to perform printing without causing separation.

FIG. 4 is an explanatory view showing an example of a printed original processed in this example, and FIG. 5 is an explanatory view showing an example of a conventional printed original.
As shown in FIG. 5A, when the original document on which the table is written is printed, as shown in FIG. 5B, the portion that protrudes from one page is divided into the next page, and the table frame and 1 The image is output with the line image divided.
However, by performing the page break process of this example, even if the document is the same as that shown in FIG. 5B shown in FIG. 4A, the page break is properly performed between lines as shown in FIG. 4B. After being processed, the table frame and the image of one line are not divided, and are output in a state of being properly distributed to each page.
In the example shown in the figure, not only the division of one line is prevented, but also the table frame divided into a plurality of pages is edited in a completed state, and a frame is added to the end of the table on the previous page. Display (print) footer information “Continued”, add a frame to the top of the table on the following page, and display (print) header information common to the first page such as “name” and “item” Yes.
As a result, it is possible to provide a kind printed document that has a good impression for the reader. However, such an editing method can be changed according to the user's preference and necessity. For example, in the application, a number of editing modes (whether or not pagination is provided) are prepared, and the user is notified in advance. It is possible to adopt a configuration that allows selection.

The above is an example of the present invention, and various modifications can be made to specific elements.
For example, although omitted in the above description, when printing of a text edited on the display screen is selected in the Web browser, the text is again retrieved from the Web server and the same editing process as that of the display document is performed. There are some that output to the printing device after performing, and in the case of such a processing method, the page break processing on the display screen described above is similarly performed on the document data for printing, Shall be printed.
In the above-described example, the operation example when the text displayed on the display screen is printed has been described. However, in actual operation, the document file acquired through the Web browser is temporarily stored in the file memory or the like of the client terminal. In many cases, this is printed later by specifying a file name or the like, and the document file may be printed without being displayed on the display screen. Therefore, in the printing process in such a case, it is also possible to provide an application that performs a page break process that eliminates the division of one line while looking at the page size and line feed as in the above-described flowchart.
Of course, the user can select whether or not to insert footer information and header information before and after the page break.
In addition, a function is provided that allows the user to select whether to execute a series of processes relating to the present invention for each terminal or for each printing process. When this process is unnecessary, printing is performed in the same manner as in the past. Of course it is also possible.
The above configuration is also included in the present invention.

It is a block diagram which shows the structure of the network system which implements the printing method by this invention. It is a block diagram which shows the structural example of the processing module which operate | moves with the client terminal shown in FIG. 3 is a flowchart showing a specific flow of a printing method executed by the client terminal shown in FIG. 1.
