Abstract

PURPOSE:To permit printers having no printing function for over line to print document containing under- and over-lines by using a system in which printing data are prepared by converting the over-line into the under-line of the preceding line. CONSTITUTION:If information on rule received from a under- and over-line detector 12 refers to the over-line, a number of line preceding the line and its field number and kind of the under-line are sent to a under-line holder 14 by an over-line/under-line converter 13. The holder 14 holds information on rule related to under line received from the converter 13. A printing controller 11 reads out only letter code from a code picture image 3 and combines it with information on under-line read out from a under-line holder 14 to prepare printing data for the line. The printing data are supplied to a printer 9. As a result, the printer 9 functions as if it has printing function for the over-line in addition to printing function for the under-line.

Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention Industrial Application Field The present invention relates to a printing control device used when printing a document created in an information processing system on a printer, and in particular to a printing control device for printing a document created in an information processing system on a printer. The present invention relates to a print control device for printing a document including overline lines on a printer lacking an overline printing function.

Documents created within conventional technical information processing systems may include overlines as well as overlines.

As shown in Figure 3, such a document is created in a code screen memory divided into lines and fields, and each field displays the character code as well as the presence of an overline or overline for it. The ruled line display code is stored. For example, if the i-th field of the m-th line of the code screen memory contains the katakana ``aiu'' and a corresponding line display code that indicates the existence of a line above the line and a line above the line, then Correspondence is displayed.

Problems to be Solved by the Invention Even if a display device such as a CRT is capable of displaying both line-up lines and line-up lines, if you try to print this on a printer and save it, the printer will not be able to print the line-up lines. It is often U7 that does not have .

For this reason, there is a problem in that only documents that lack striking lines can be created and printed.

Structure of the Invention Problems to be Solved by the Invention The printing control device of the present invention which solves the above-mentioned problems of the prior art includes a detection means for detecting a striking line and a striking line from each line in a document to be printed; A conversion/holding means that converts the detected line as it is and converts the line to the line immediately above and retains the line, the contents of this conversion/holding means, and the line and line in the document to be printed. The printer is configured to include a print control means for creating print data by compositing portions excluding the print data and supplying the print data to the printer.

Hereinafter, the operation of the present invention will be explained in detail together with examples.

Embodiment FIG. 1 is a functional block diagram illustrating the configuration of a document creation system in which a print control device according to an embodiment of the present invention is used.

This document creation system uses CPU 1. Main memory 2, code screen memory 31 display control section 4. CRT5, keyboard 6, keyboard interface 7, document file 8
and a printer 9.

The print control device t10 according to an embodiment of the present invention is installed between the code screen memory 3 and the printer 9 of the document creation system, and the print control unit 111 line is underlined.

The upper line detecting unit 121 includes an upper line/underline converting unit 13 and an upper line holding unit 14.

The code screen memory 3 holds coded document information for one screen displayed on the CRT 5 via the display control section 4 in editing units called fields.

When the CPUI receives a print command from the keyboard 6 to the printer 9 via the keyboard interface 7, it starts the print control device 10.

First, the coded document stored in the code screen memory 3 is scanned field by field within each line by the one-line over-line detection document 12 of the activated printing control unit 210, and the over-line and over-line detection documents The border display code is checked to indicate its presence.

Every time a ruled line display code is detected, ruled line information regarding the type of line number, inline field number, two lines underline, one line and overline is notified from the line and line detection unit 12 to the line underline detection unit 13. .

The launch line/row underline conversion unit 13 converts the launch line 1 line overline detection unit 1 into
If the ruled line information received from 2 is related to the launch line,
The line number, field number, and type of line are passed to the line line holding unit 14.

On the other hand, the launch line/line underline converter 13 converts the launch line.

If the ruled line information received from the launch line detection unit 12 relates to a launch line, the number of the line immediately above the line.

The field number and type of launch line are stored in the line line holding section 1.
Pass it to 4. In other words, the 13th line up/line underline conversion unit 13 is as follows:
When the ruled line information regarding the launch line of the i-th field of the m-th row is received, the ruled line information regarding this launch line is
It is converted into ruled line information regarding the upstroke line of the i-th field in the first row, and is passed to the overline line holding unit 14.

The line top line holding unit 14 holds ruled line information regarding only the top line received from the top line/line bottom line conversion unit 13. For example, as shown in FIG.
All of the ruled line display codes included in fields 1 to n of a row are held in the above-line line holding section 14 as over-line information, and all the ruled line display codes of the m-th row are also held as over-line information.

The print control unit 11 starts reading out the code document from the code screen memory 3 and reading out the ruled line information from the above-line line holding document 14, slightly after the start of the detection, conversion, and holding operations of the ruled line information. As illustrated in FIG. 2, the print control section 11 reads out only the character code excluding the ruled line display code from each field of each row of the code screen memory 3, and reads this out from the above-line line holding section 14 for the corresponding line. The print data for that line is created by combining it with the line information of the corresponding field, and is sent to the printer 9 via the output cover.
supply to.

As a result, as shown in FIG. 3, for example, the i-th field of the m-th row in the code screen memory holds the ruled line display code consisting of both the uchami line and the uchami line, and the character code for the katakana "aiu". In the case of The printer 9 functions as if it had a function of printing the line in addition to the function of printing the line.

Effects of the Invention As explained in detail above, the printing control device of the present invention has the following effects:
Since the printing data is created by converting the launch line into the launch line immediately above, even a printer lacking the launch line printing function can print the launch line and the document including the launch line.
