Abstract

PURPOSE:To raise an efficiency of printing a lateral extension character by an arbitrary magnification by recognizing a magnification (n), selecting a constant (m) of a minimum integer number by converting it to the integer number, increasing the interval of dots and the number of dots to be printed laterally by (n x m) times, setting the feeding speed of a printing carrier to l/m, and incorporating steps of printing (nXm) pieces of dots at the same responding speed as a normal character. CONSTITUTION:A controller 5 first identifies by an identifier 50 a desired character size 'n' at a printing sentence in one row, and selects a constant 'm' to be converted to integer number by multiplication by a selector 51. In this case, an enlarged printing control is adapted by selecting a minimized integer number. Further, it is enlarged by 'nXm' times at the time of converting dots of the printing data by a converter 52. The data are printed by a printer 4 at a responding speed corresponding to the normal character of a printing head l at a speed 53 of 'l/m' at the time of printing the normal character. Thus, the character enlarged by 'n' times as large as the lateral size is printed. It is not necessary to particularly control a dot pitch, but printing density can be made uniform by easy control. Even if the normal printing character and the enlarged printing character are mixed, it can be printed by one feeding in one direction.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a printing control method for a printing device that prints the processing results of an electronic computer on paper such as a form, and in particular, The present invention relates to a printing control method for a printing device suitable for efficiently printing magnifications.

[Prior Art] Currently, electronic computers are used to process various data, and the output of the processing results is usually printed on paper using a printing device.

In particular, when printing, by changing the size of the print in accordance with various situations, it is possible to make it easier for the user to see.

In order to change the print size and density, in the prior art, the response speed of the print head of the printing device and the feeding speed of the print carrier are changed.

For example, there is one described in Japanese Patent Application Laid-Open No. 56-82273. This changes the size of the print and also changes the print density in order to prevent the density of the print from decreasing due to the change in size.

That is, by changing the moving speed of the print carrier in accordance with the dot pitch of the printed characters, desired characters can be obtained without changing the response speed of the print head.

[Problem to be solved by the invention]

Currently, for example, when issuing a carryover passbook using an automatic cash handling machine, only the name is printed on the cover, and only in the horizontal direction.
Characters expanded by 1.5 times may be used. This is because, in bankbooks such as Corporate Ito, when characters are expanded twice horizontally, no characters can be inserted in the - line.

However, when printing horizontal extended characters other than integral multiples,
In conventional printing devices, the size of printed characters can be changed by changing the pitch of dots. Therefore, it is not possible to make the printing density of normal characters and horizontally expanded characters uniform.

Furthermore, in order to change the pitch of the dots, it is necessary to change the feed speed of the print carrier or change the timing settings of the dot fire and the phase advance pulse of the motor in the control section. Therefore, when printing characters of different sizes in the - line, a certain distance was required to change the pitch of the dots.

For this reason, a printed message in which characters of different sizes are lined up at a certain distance or less cannot be printed, so there is a problem that the printed message must be divided.

The purpose of the present invention is to solve these problems of the prior art, and to print normal characters arranged at a certain distance or less in a line and expanded characters in the horizontal direction at an arbitrary magnification, without changing the dot pitch and with simple control. By providing a printing control method for a printing device that enables printing of mixed characters with uniform printing density and by only one-way feeding operation, reducing costs and improving throughput. be.

[Means for Solving the Problems] In order to achieve the above object, the printing control method of the printing device of the present invention provides a printing control method for a printing device according to the present invention. a step of recognizing n;
A step of selecting a constant m, which is the smallest integer that makes this magnification n an integer, by multiplication, and a step of increasing the interval between dots of the character print data and the number of printed dots for each dot by a factor of n×m in the horizontal direction. and further, the step of setting the printing carrier feeding speed to 1/m of the normal character printing speed, and printing n×m@ dots at the same print head response speed as when printing normal characters. The method is characterized by including the steps of:

[Operation] In the present invention, the control section first identifies the desired character size rnJ in the printed message in the - line.

For example, for 1 normal character, rn=IJ, and horizontal 1.
If it is a 5-fold expansion, it is identified as rn-1,5J, and if it is a 2-fold horizontal expansion, it is identified as rn=24.

Next, a constant rmJ that can convert the desired character size rnJ into an integer by multiplication is selected. In this case, as "m",
By selecting the smallest integer, the enlarged print M can be controlled appropriately.

Furthermore, when converting print data into dots, it is expanded by a factor of n×mJ.

In this way, print data expanded by rn x mJ is printed at a speed of "N/m" when printing normal characters, and
Printing is performed at the print head's response speed for normal characters.

In this way, characters whose horizontal size is expanded by [n3 times] are printed. When printing these expanded characters, there is no need to particularly control the dot pitch, and the print density can be made uniform with easy control. Furthermore, even if normal printing characters and extended printing characters coexist, they can be printed in one direction with a single feeding operation.

After going through step 8, the horizontal 1.
This shows how the five-fold expanded print character "11" 9 is obtained.Hereinafter, the method for printing each character will be explained based on the processing operation of the printing device shown in FIG.

First, a conventional printing method for normal printing rllJ6 will be explained.

The magnification is "1" and "1" is selected as the constant. The control unit 5 in FIG. 1 performs normal dot conversion, that is,
The print head converts the dot pattern of the sent print data "11" so that it can be reproduced on paper.

Then, the print carrier 2 shown in FIG. 1 transmits a constant (usually "1") that corresponds to a predetermined feed speed to the drive control unit 4 shown in FIG. 1 together with the converted print data.

The drive control unit 4 shown in FIG. 1 drives the print head 1 and pulse motor 3 shown in FIG. 1 based on the information to perform printing. −For boat fishing, in this case, the pitch of the dots is −
Corresponds to pulse.

In this way, the conventional normal printing rllJ6 is printed.

Next, this conventional normal printing "11" 6 is printed horizontally as 1.
We will explain how to print with 5x expansion.

First, the horizontal expansion rate r1.5J of the specified printing is recognized by the expansion rate recognition 1as50 in FIG. Select the constant "2" which is the smallest integer to be an integer (here, the result is "3").

]l! The extended dot converting unit 52 of I converts the sent print data "11" by 3 times the horizontal direction (expansion rate rx, 5) based on the recognized horizontal expansion rate ri, 5'' and the selected constant r2).
JX constant "2"). At this time, the print data first becomes horizontal three-fold sparse expansion data N, lJ7 in which the dot spacing is expanded.

That is, the spacing between each dot is tripled horizontally, and the character size is also tripled horizontally. Next, the horizontal triple-density expanded data N,+'g with an increased number of dots is obtained.

That is, the horizontal triple sparse expansion data N1. At J7, new dots are provided between the blank dots, resulting in print data that is three times the width.

Then, the speed control signal generation unit 53 in FIG.
Based on J, a control signal is generated to set the feed speed of the print carrier 2 in FIG. 1 to the normal rl/2J.

In this way, the dot pattern converted to 3 times the width shown as 3 times the width dense expansion data "11" 8.

The control section shown in FIG. 1 sends a control signal for reducing the feed speed of the print carrier 2 shown in FIG. 1 to 1/2 of the normal speed to the drive control section 4 shown in FIG.

The drive control section 4 shown in FIG. 1 drives the print head 1 and pulse motor 3 shown in FIG. 1 based on the information to perform printing.

According to the invention, the pitch of the dots corresponds to 1/2 pulse.

In this way, the horizontal 1.5 times expanded print rl IJ9 is obtained.

As explained above using FIGS. 1 to 3, according to this embodiment, - characters of different sizes lined up within a certain distance in a line, for example, normal characters and characters other than integral multiples, Even when printing horizontally expanded characters, the dot pitch and printing carrier feed speed are made equal to ensure uniform printing density and -
Printing can be performed by multiple feeding operations.

[Effects of the Invention] According to the present invention, a mixed character of one normal character and an extended character printed at an arbitrary horizontal magnification can be printed with uniform printing density in a - line.
Moreover, with a simple circuit, without changing the dot pitch,
Printing can be performed with only one direction of feeding at the same feeding speed, making it possible to reduce costs and improve throughput.
