Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document editing apparatus, a document editing method, and a storage medium storing a computer-readable program, and more particularly to displaying a print margin on an editing screen for creating a document. The present invention relates to a document editing apparatus and method, and a storage medium.

[0002]

2. Description of the Related Art In a conventional printable document editing system, information (print margin) of a printable area from a printer driver which is currently selected by an application is stored in an OS.
When a user operates to set an unprintable area in the page setting (margin setting can be performed) of a document to be obtained through an API provided by the user and displays a warning dialog to print to the user Editing operations are allowed within the margin. In addition, some applications have a function of displaying a margin (margin) width on an edit screen by a dotted line or the like so that a user can be aware of a margin (margin) width generated at the time of printing.

[0003] In recent years, the performance of printing apparatuses has been improved, and there are many printing apparatuses capable of performing double-sided printing.
In a printing apparatus, particularly an electrophotographic printer, it is necessary to attach a recording medium (recording paper) to a transfer drum or a transfer belt, and it is necessary to maintain a potential for transferring the toner to a predetermined value or more. Due to such restrictions, a printable area (print margin) is required. This print margin differs depending on the type of printing device, and
It differs depending on the margin. For example, in an electrophotographic printer, when printing A4 portrait in the vertical direction,
The print margin is 6.5 mm above, 5.0 mm below, and left 6.
0 mm and 6.5 mm on the right.

Further, in recent years, the PC penetration rate has increased, and as a result, users who use the printing apparatus have come to use the printing apparatus not only for creating text documents but also for creating DTP (desktop publishing) such as New Year's cards. ing. Here, when a printing apparatus is used to create the DTP, there is a high demand for printing images such as photographs, graphics, and characters to the very end of the print margin.

[0005]

As the demand for printing to the full print margin is increasing as described above, the demand for printing to the full print margin not only in single-sided printing but also in double-sided printing in the future is increasing. Is expected to increase.

However, according to the automatic double-sided printing function of the current printing apparatus, when a recording medium is fed from the top of A4 portrait and printed, the back side re-supplied from the automatic duplex unit has an A4 portrait. The recording medium is re-fed and printed from below (the image is also created upside down)
The print margins are different from top to bottom, left and right. Nevertheless, the application considers the print margin information obtained from the driver on only one side, and if the user takes it into account and creates an image or text that fills the print margin, the print result on the back side will be There is a problem that it is cut off on the way.

In a printing apparatus having a plurality of paper feed stages and capable of feeding a recording medium in a plurality of directions (A4 lengthwise direction and A4 widthwise direction), hardware limitations of the printing apparatus cause a problem.
The print margin differs depending on the paper feeding direction. For example, when the recording medium is fed in the A4 portrait direction, the print margin is 6.5 mm above when viewed from the image direction of the print result.
Bottom 5.0mm, left 6.0mm, right 6.5mm,
When the recording medium is fed in the A4 horizontal direction, the print margins are 6.5 mm above, 6.0 mm below, 6.5 mm left, and 5.0 mm right when viewed from the image orientation of the print result. However, the print margin information acquired by the application from the conventional printer driver considers only the paper feed direction used by the printer driver in the default (for example, A4 horizontal direction). When a print instruction is given (for example, in the A4 vertical direction), a print margin different from the print margin considered in the application is generated, and there is a problem that a print result desired by the user cannot be obtained.

The present invention has been made in view of the above problems, and a first object of the present invention is to notify a user of a print margin in consideration of double-sided printing at the time of editing a document and to perform an editing operation. The purpose is to:

Further, a second object of the present invention is to provide a printing apparatus in which a printing margin in consideration of a paper feeding direction of a recording medium is provided.
An object of the present invention is to notify a user at the time of editing a document and to perform an editing operation.

[0010]

A first document editing apparatus according to the present invention includes a recognizing means for recognizing a print margin, which is an unprintable area, based on device information obtained from a currently selected printer driver. In order to support double-sided printing, a display control means for identifiably displaying the print margin on the back side during double-sided printing in the document editing area when the opposite print margins are different.

Further, the display control means displays an auxiliary line in the document editing area based on a wide width of the opposed print margin.

Further, the display control means displays an auxiliary line based on a wide width in parallel with the auxiliary line based on the narrow width on the document editing area side on the narrow width side of the opposed print margin. .

Further, the display control means displays auxiliary lines for upper, lower, left and right print margins.

Further, the printer driver further includes driver setting determining means for determining whether or not double-sided printing is designated by the selected printer driver, and the driver setting determining means designates double-sided printing by the printer driver. If it is determined that the print margin has been set, the display control means displays the print margin on the back surface during double-sided printing in the document editing area in an identifiable manner.

Further, the apparatus further comprises a document setting judging means for judging whether or not double-sided printing has been designated for the document file when opening the document file. On the other hand, when it is determined that double-sided printing has been designated, the display control means causes the print margin on the back side during double-sided printing to be identifiably displayed in the document editing area.

When the printer driver in the selected state specifies the paper feeding direction of the recording medium, the display control means sets the print margin in the document editing area in consideration of the paper feeding direction of the recording medium. Is displayed.

The present invention is also realized by a similar process in a storage medium storing a method and a program.

Further, the second document editing apparatus according to the present invention includes a recognizing means for recognizing a print margin, which is an unprintable area, based on device information obtained from a currently selected printer driver, Display control means for identifiably displaying a print margin recognized by the recognition means in the document editing area in consideration of the paper feeding direction of the recording medium.

Further, the printer driver further comprises designation means for designating the paper feeding direction of the recording medium at the time of printing, and acquisition means for acquiring the paper feeding direction in which the normal recording medium is fed from the printer driver. When the acquired paper feed direction is different from the supplied paper feed direction, the display control means causes the recognized print margin to be shifted and displayed.

Further, there is provided editing means for editing a document on the document editing area in which the print margin is displayed.

The present invention is also realized by the same steps in a storage medium storing a method and a program.

The editing processing program (including the printing processing program) of the present invention is stored in the ROM 102 or the external storage unit 109.
3 is executed by the CPU 101 to realize this function.

Next, the operation of this embodiment will be described. FIG.
FIG. 7 is a diagram showing a series of processes from selection of a sheet to display of a margin line on an editing screen. In this processing, the following processing is performed when a document editing application (this document editing program) is started and a new file is generated.

In step 201, a process of selecting a paper size to be used as a new file is performed in the document editing application. This is because CPU1
Based on the document editing program, paper size information is read from a paper size file supported by the document editing program shown in FIG.
As shown in FIG. 11, each paper size is displayed, and an arbitrary paper size is selected according to a selection instruction from the user. When the paper size of the new file is determined, the process proceeds to the next step 202.

In step 202, a process of selecting a printer to be used is performed in the document editing application. This is because the CPU 1 reads each printer information from a printer selection file that can be output by the document editing program shown in FIG. 4 based on the document editing program, and selects a printer desired by the user according to a selection instruction from the user. I do. Here, FIG. 11 will be described a little.

FIG. 11 shows an example of a user interface screen 1101 (hereinafter, referred to as a user interface (UI)) of an application generated based on the document editing program. This UI is displayed when the application is started and “New” is selected from “File” in the menu 1105. Menu 1
"New" of the menu icon 1103 as in the case of 105
The same processing is performed by clicking (instructing) by operating a pointing device such as a mouse.
The dialog 1102 is for prompting the user to input a predetermined setting. In this application, the user first selects a paper size, a paper direction, and a printer (printing device) as an output destination. This application is different from a general document creation application in that when creating a file, an output destination printer is set. By doing so, the information of the output destination printer is stored in association with each file,
This eliminates the need to manually change the output destination printer each time the user opens another file. As described later, when a document file is opened and a document is edited, the output destination associated with the document file is edited. Can be displayed on the document editing area.

Reference numeral 1104 denotes an operation icon for instructing editing of a currently open document file. The user operates this icon to insert a clip art or a photographic image. Or add text with message labels.

FIG. 12 is an enlarged view of the dialog 1102.
It is. In FIG. 12, reference numeral 1201 denotes a pull-down menu, in which paper sizes defined by the paper size file in FIG. 3 are displayed as candidates, and a user can select from the paper sizes. Reference numeral 1202 denotes a radio button for designating the paper direction, and it is possible to select either portrait or landscape orientation.

Reference numeral 1203 denotes a pull-down menu for selecting a printer. The output destination port (printer name) of the printer driver installed in the document editing apparatus is displayed, and the output destination printer can be designated. Here, the output destination printer driver installed in the document editing apparatus is a local printer or an LA printer.
In addition to a network printer connected to N, a printer name of a print shop for making a print request via the Internet can be selected.

When the user selects a paper size, a paper direction, and an output destination printer on this UI (FIGS. 11 and 12), the process proceeds to step 203.

In step 203, it is determined whether or not the paper size has been correctly set in the above steps. If the paper size has been correctly set, the process proceeds to step 204. If not, the process proceeds to step 202. Return to processing.

In step 204, a document editing process in this application is performed. This document editing process will be described with reference to FIG.

FIG. 5 is a diagram for explaining in detail the flow of the document editing process in step 204 of FIG.

In step 501, in the present application, a process of inquiring of the currently selected printer driver about the print area is performed. The CPU 101
AP provided by OS based on this document editing program
The printer driver in the selected state is inquired of a print area (or a print margin which is an unprintable area) via I. In step 502, device information including a print margin (margin value) is obtained from the printer driver via the API. The device information may include, in addition to the print margin, whether or not double-sided printing is set in the print setting of the printer driver, the setting of the paper feeding direction of the recording medium, and the like. In that case, it is possible to use an extended API.

In step 503, the CPU 101 stores the acquired device information in the margin information 1 (FIG. 6) in the format setting value storage area 132 of the RAM 103 based on the document editing program. It is set and stored in the margin information 1 in the memory (upper margin value 601, lower margin value 602, left margin value 603, right margin value 604, respectively).

Then, in step 504, the CPU
1 judges whether “upper print margin <lower print margin” as a margin comparison.

If this condition is satisfied, step 506 is executed.
The CPU 101 sets the lower margin value and the same value as the upper margin value in the margin information 2 shown in FIG. 7 in the format setting value storage area 132 of the RAM 103 (the upper margin value 701 and the lower margin value, respectively). 702).

If the condition is not satisfied in step 504, the process proceeds to step 505, where the CPU 1
"Top print margin> bottom print margin" as a comparison of margins
Is determined.

If this condition is satisfied, step 507 is executed.
The CPU 101 sets the upper margin value and the same value as the lower margin value in the margin information 2 shown in FIG. 7 in the format setting value storage area 132 of the RAM 103 (the upper margin value 701 and the lower margin value, respectively). 702).

If the condition of step 505 is not satisfied, the upper print margin and the lower print margin have the same value, so that the process proceeds to step 508, where the CPU 101
The upper print margin and the lower print margin are set in the margin information 2 shown in FIG. 7 in the format setting value storage area 132 of the AM 103 (the upper margin value 701 and the lower margin value 7 respectively).
02).

Similarly, in step 509, the CPU
1 judges “left print margin <right print margin” as a margin comparison.

If this condition is satisfied, step 511 is executed.
The CPU 101 sets the right margin value and the same value as the left margin value in the margin information 2 shown in FIG. 7 in the format setting value storage area 132 of the RAM 103 (the left margin value 703 and the right margin value, respectively). 704).

If the condition is not satisfied in step 509, the process proceeds to step 510, and the CPU 1 determines "left print margin> right print margin" as a margin comparison.

If this condition is satisfied, step 512
The CPU 101 sets the left margin value and the same value as the right margin value in the margin information 2 shown in FIG. 7 in the format setting value storage area 132 of the RAM 103 (the left margin value 703 and the right margin value, respectively). 704).

If the condition is not satisfied in step 510, that is, if the left print margin and the right print margin have the same value, the process proceeds to step 513, where the CPU 101
The left margin value and the right margin value are set in the margin information 2 shown in FIG. 7 in the format setting value storage area 132 of the AM 103 (upper margin value 701 and lower margin value 702, respectively).

When the setting of each margin value is completed, the process proceeds to the display processing of step 205.

Next, FIG. 8 is a diagram for explaining in detail the flow of the display processing in step 205 of FIG.

At step 801, the CPU 101
Based on the document editing program,
