Description

Description: BACKGROUND OF THE INVENTION The present invention relates to an apparatus for outputting data to output areas of various sizes.

[Conventional technology]

In an office computer or the like, in order to output data in accordance with an output format such as a form, the output position of the data on the form is specified at the time of system design. That is, the coordinates indicating the data output position are described by the program in accordance with the printer and output format used by the user.

[Problems to be solved by the invention]

In order to change the printer to be used and the output position, it was necessary to modify the program, and the user could not change it freely and easily. Further, in the case of designing a system so as to correspond to several printers, it is necessary to create a program corresponding to each printer, which requires a large amount of labor, and the degree of freedom of the user is designed in advance. Limited within the range.

SUMMARY OF THE INVENTION An object of the present invention is to enable output to output areas of various sizes without any need for modifying the program, and for making the system design easy.

[Means for Solving the Problems] The means of the present invention are as follows.

The output position storage means 1 (see the functional block diagram of FIG. 1, the same applies hereinafter) stores an output position of output data on coordinates divided by a predetermined number of rows and a predetermined number of columns.

The paper size designation means 2 designates the paper size of the print paper for outputting the output data.

The conversion unit 3 specifies an output area for outputting the output data to the specified printing paper based on the paper size specified by the paper size specification unit 2, and determines the size of the specified output area. The output position stored in the output position storage means 1 is converted into an output position on the output area based on the output position.

The output control means 4 outputs the output data to the output position converted by the conversion means 3.

[Operation] The operation of the means of the present invention is as follows.

The output position storage means 1 stores the output position of the output data on the coordinates divided by the predetermined number of rows and the number of columns, and the paper size designation means 2 designates the paper size of the print paper for outputting the output data. Then, the conversion unit 3 specifies an output area for outputting the output data to the specified print paper based on the paper size specified by the paper size specification unit 2, and specifies the output area. The output position stored in the output position storage means 1 is converted into an output position on the output area based on the size of the output area, and the output control means 4 stores the output data in the output position converted by the conversion means 3. Output.

Therefore, the output data can be output to the output position of the output area based on the specified paper size only by specifying the paper size of the printing paper for outputting the output data.

〔Example〕

Hereinafter, an embodiment will be described with reference to FIGS. 2 to 8.

 First, the principle of the present embodiment will be described.

FIGS. 4 (a) and 4 (b) are views showing the effective printing area 21 on the printing paper 20 of the liquid crystal printer and the dot printer. FIG. 4 (a) shows the case of the liquid crystal printer, and FIG. This shows the case of a dot printer. The actual print effective area
21 is an area on the printing paper 20 that can be printed by the printer,
In FIGS. 7A and 7B, the non-printable area 22 is indicated by oblique lines. In the case of a liquid crystal printer as shown in FIG.
The upper end, the lower end, the left end, and the right end of the printing paper 20 cannot be printed. In the case of a dot printer, the left end and the right end of the printing paper 20 cannot be printed as shown in FIG. ing. Therefore, even when printing on the printing paper 20 of the same size, the area of the effective printing effective area 21 differs depending on the type of the printer. In addition, if the size of the printing paper 20 is different, the area of the actual printing effective area 21 is different, and even when printing on the same size printing paper 20 with the same printer, the orientation of the paper (vertically or horizontally The shape, or shape and area of the effective printing effective area 21 differs depending on whether or not it is placed.

For this reason, in the present embodiment, a set of square coordinates is set. The square coordinates are coordinates obtained by virtually setting a print sheet of a specific size and dividing the sheet by an arbitrary number of rows and columns. This virtual printing paper is hereinafter referred to as a logical space.

FIGS. 5A and 5B are diagrams showing the configuration of eye coordinates.

By decomposing the logical space 30 shown in FIG. 7A by the number of rows a and the number of columns b, a × b squares are generated in the logical space 30 as shown in FIG. Each generated square is defined by a row and a column as shown in FIG.
0) to (a-1, b-1).

In this embodiment, the print position of the print data is specified by the square coordinates, and when actually printing on a printer, the square coordinates in the logical space 30 are determined by the type of the printer, the size of the printing paper, and the orientation of the printing paper. Is automatically converted to the actual coordinates on the actual print effective area determined by the above and printed at the position of the actual coordinates.

Here, FIG. 6 shows the actual coordinates set in the actual print effective area 21. The real coordinate system is a coordinate system that specifies the print dot position on the real print effective area 21 and is an orthogonal-XY coordinate system in which the dot position at the upper left corner of the real print effective area 21 is the origin (0,0). ing. Accordingly, the dot position at the upper right corner of the actual print effective area 21 having the n ₁ (horizontal) × n ₂ (horizontal) dot configuration is (n ₁ −1,
0), the dot position at the lower left corner is (0, n ₂ -1), and the dot position at the lower right corner is (n ₁ -1, n ₂ -1).

Next, a description will be given of a method of converting the grid coordinates configured as described above into real coordinates.

7 (a) to 7 (d) are diagrams showing a state of conversion from the grid coordinates to the actual coordinates on the actual print effective area 21. FIG.

For example, as shown in FIG.
Suppose a row is divided into 10 × 10 squares of 10 cases.
At this time, when printing on the A4 size paper 40 in the portrait orientation with the liquid crystal printer, the actual print effective area 41 of the paper 40 is set in the logical space.
As in the case of 30, the image is equally divided into 10 × 10 squares 41a. Then, the dot size of the equally divided squares 41a i.e., determine the number of dots d _y transverse dot number d _x and the vertical direction, the number of the dots d _x, corresponding to the square coordinates based on d _y The actual coordinates to be calculated. That is, when the squares coordinates is assumed to be (x _1, y _1), X-coordinate x ₂ of the actual printing effective region 41 by multiplying the number of dots d _x lateral squares in x ₁ is, y ₁ The Y coordinate y ₂ on the actual print effective area 41 is obtained by multiplying the dot number d _y in the vertical direction of the stitches. In this way, the logical space
30 square coordinates (x ₁ , y ₁ ) are converted to actual coordinates (x
₂ , y ₂ ) and print the data at the position of the obtained real coordinates (x ₂ , y ₂ ).

Similarly, when printing with a liquid crystal printer on landscape B5 size paper 50 and printing with a dot printer on landscape A3 size paper 60, the coordinates from the eye coordinates to the actual coordinates using the above-described method. Exchange is performed and printing is performed at the position of the actual coordinates (see FIGS. 7B and 7C). FIG. 7 is a diagram showing where the actual paper is printed when the coordinates on the square coordinates shown by oblique lines are (2, 2).

The square coordinates are logical coordinates obtained by decomposing a virtual printing paper of a predetermined size into uniform squares according to the number of rows and columns, and the logical coordinates are obtained for printing paper of any size. It can be converted to real coordinates for the actual print effective area.
