DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a database print format determining apparatus for determining a format for printing data items stored in a database.

[0002]

2. Description of the Related Art Conventionally, when printing data items of a database, first select the data items to be printed,
Printing parameters such as paper size, paper direction, character spacing, and line feed width were specified. If the selected data item does not fit on the specified paper, you must change the print parameter specification or reduce the number of data items to be printed. The repetition of such a change operation becomes considerably troublesome.

[0003]

In printing a database having a long record length, if a print parameter is specified after selecting a data item to be printed, the width of the data item does not fit on the paper, and the print parameter specification is changed. Even so, the width of the data items still does not fit on the paper, and eventually the number of data items must be changed, resulting in unnecessary work. Conversely, taking too much security can create excessive margins to the right of the paper, which can result in wasted paper. Also, B4 is automatically added to the selected data item.
You may be in trouble when you want to use vertical writing with horizontal writing on paper.
