Abstract

PURPOSE:To enable line space and character space in a printing format to be finely changed, by multiplying a line space and a character space previously specified by the operator by a scaling factor separately set, thereby obtaining an actual line space and an actual character space, and causing a printer to print according to the values thus obtained. CONSTITUTION:When execution of a printing operation is selected, a printing format menu is displayed on a CRT screen of a CRT display device 8 under the control of a CPU 1. According to the menu, appropriate ones of line space values and character space values for printing which are previously provided in a device are selected in addition to a printing format such as paper size and printing direction, and a scaling factor is set. The information thus selected or set is sent to a calculating circuit 13, which multiplies the selected line space value and the selected character space value by the scaling factor. The results of calculation are sent to a printer controller 12 as an 'actual' line space value and an 'actual' character space value, and a document text is outputted to a printer 11 on the basis of these values.

[Problem that the invention seeks to solve]

Since the print control device in conventional Japanese word processors is configured as described above, the 9-character spacing per line can only take values that are prepared in advance for the print format, and it does not necessarily match the print format requested by the operator. There was a problem that it could not be satisfied.

The present invention was made to solve the above-mentioned problems, and an object of the present invention is to provide a print control device that can finely change the line spacing of nine characters in a print format.

[Means for solving problems]

The print control device according to the present invention multiplies the two-character line spacing specified by the operator in advance by a separately set enlargement rate and reduction rate to obtain an execution interval and an actual character interval, and causes the printer to print according to these values. This is what I did.

[Effect]

The arithmetic unit in this invention has a line spacing of 9 characters specified by the operator and a separately specified enlargement rate.

By multiplying by the reduction ratio, the execution interval and actual character interval during actual printing are determined.

[Embodiments of the invention] An embodiment of the present invention will be described below with reference to the drawings.

This is an arithmetic circuit that calculates the execution interval and actual character interval when actually printing from the line interval value 9 character interval and the enlargement/reduction ratio stored in advance in an external storage device.

Next, the operation of the embodiment will be explained.

When the device is powered on, the DMA controller (3)
Then, under the control of the file memory controller (4), the program information stored in the external storage device 1, for example, the magnetic disk device (6), is loaded into a predetermined program storage area of the MMU t2+, and then the MMU

Under the control of the C/B-CRT controller (9)
Drive the T-display device (8) and display the work menu on the CRT screen. From the work menu displayed on the CRT screen, the operator operates the keyboard (7) to select the subsequent processing work.

Here, when execution of the print operation is selected, the following operations are performed under the control of the CPU (1). First, a print format menu is displayed on the CR'r screen of the CRT display device 1B+. Follow this menu.

In addition to print formats such as paper size and print direction, line spacing values for printing that are provided in advance by the device.

Along with selecting an appropriate character spacing value.

Once the enlargement/reduction ratio is set, these pieces of information are sent to the arithmetic circuit t13, and each of the 2-line spacing value and the 9-character spacing value is multiplied by the enlargement/reduction ratio. This result is.

These are sent to the printer controller i1■ as the "Fu" line spacing value and the "actual" character spacing value, and based on these values, the printer I
Output the document to.

The above operation will be explained using a specific example.

Generally, when the printer 111) is a dot printer that prints nine characters as a dot matrix, the zero line spacing and character spacing are specified in units of dots. That is, one dot is the distance between adjacent dots in the dot matrix. For example, if the operator sets the spacing between two lines to 12 dots,
Specify the character spacing as 8 dots and set the enlargement/reduction ratio to 360%.
Suppose we set These values are sent to the arithmetic circuit +13, and the "center" row spacing is t-43 dots, and the "real" row spacing is t-43 dots.
Calculate the character spacing as 28 dots. The calculation result shall be rounded down to the decimal point. When the "actual" line spacing and "actual" character spacing are sent to the printer controller α2,
When the printer controller finishes printing one character,
The head of printer αυ is moved in the printing direction by 28 dots, and when printing for one line is completed, the platen of printer llυ is rotated in the printing direction by 43 dots.

FIG. 2 shows a flowchart of the print control i [177 production].

In the above embodiment, an arithmetic circuit is provided to calculate the "actual" line spacing and "actual" character spacing.

Even if these calculations are programmed and performed by the CPU,
The same effects as in the above embodiment are achieved.

〔Effect of the invention〕

As described above, according to the present invention, a simple arithmetic circuit is simply added without modifying a conventional printer controller, so that a significant functional improvement can be achieved with a slight increase in cost.
