Abstract

PURPOSE:To ensure an easy-to-see display of the print data with the use of the same image of a pattern as the print data by converting the character data into the image data and displaying the image data after magnifying or reducing it in response to the size of the single screen of a display device. CONSTITUTION:The print data on a page which is designated by an operator via a print data file 5 and a service means 4 is read as the character data. A code data conversion means 2 converts the print data on a page of a printer into the image data. At the same time, the size of the image data equivalent to the page of the printer is also known as well, and stored in the memory of the means 2. Then an image data magnifying/reducing means 3 performs an optimum magnifying/reducing operation of the image data based on the size information on the means 2 in response to the screen size of a display device 6. Then the image data is shown on the device 6. Thus the same image of a pattern as the print data is obtained and the print data can be easily seen.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a print data display method for displaying data to be printed on a printer device on a display device.

(Prior Art) Conventionally, a method for displaying this type of print data on a display device has been to sequentially send the print data to the display device in its original format as code data.

(Problems to be Solved by the Invention) However, the number of characters that can be displayed in one line on a display device is smaller than the number of characters that can be displayed on one line on a display device, whereas the conventional printer device prints data in one line. Therefore, when displaying print data on a display device, one line of data is displayed by cutting off the portion that does not fit on one line on the screen of the display device, or one line of data is displayed on multiple lines on the screen of the display device. It was displayed using means such as folding back. For this reason, there is a drawback that the print result of the printer device and the pattern displayed on the screen of the display device are different from those of the previous page and are difficult to see.

The present invention has been made in view of the above problems, and is a print data display method that can make the print pattern of a printer device and the display pattern of a display gray device the same image, and can make the display of print data easier to see. The purpose is to provide

(Means for Solving the Problem) The problem is to read print data from a file in which the print data to be output to a printer device is stored as character data and display the print data on a display device. Code data conversion means for converting into data and conversion result j''-RanaR7J
image data enlargement/reduction converting the image data according to the size of one screen of the display device;
This problem can be solved by providing a reduction means.

(Function) Since the configuration is as described above, the print data can be outputted to the Nice Play device as image data, so that the image can have the same pattern as the print data. Therefore, it is possible to make the display of print data easier to see.

(Example) An example of the present invention will be described below with reference to the drawings.

The drawing is a block diagram showing the configuration of this embodiment.

In this embodiment, character data (
A print data reading processing unit 7 that sequentially reads print data (print data), a code data conversion unit 2 that converts character data (code data) into image data, and a display device 6 that displays image data for one page of the printer obtained as a result of conversion. An image data enlarging/reducing means 3 for enlarging/reducing the image data to the size of one screen, and when there are multiple pages of print data,
and a service means 4 for reading any specified page.

Next, the use of the print data display method of this embodiment will be explained.

From the print data file 5 in which print data is stored, the print data of the page specified by the operator is read as character data through the service means 4, and the print data of one page of the printer is converted into image data by the code data conversion means 2. . At the time of this conversion, the size of the image data for one page of the printer is also determined and stored in the memory of the code data conversion means 2. Next, based on the size information of the image data obtained by the code data converting means 2, the image data enlarging/reducing means 3
The image data is enlarged/reduced by finding the optimum enlargement/reduction ratio according to the screen size of the display device 6 and sent to the display device 6.

As described above, according to this embodiment, the display operation 6
It is possible to display characters, etc. in the same pattern as the printer's printing pattern. Therefore, the print data on the display device 6 can be easily viewed.

<Effects of the Invention> As explained above, by using the print data display method of the present invention, even when print data is output to a display device, the image data is displayed on the display device in the same pattern as when it is printed by a printer device. This has the advantage that the content of the print data can be displayed on a single screen, making it easier to see the contents of the print data.
