Abstract

PURPOSE:To make it possible to sharply emphasize printing by overlap typing, by performing printing by shifting lately printed data by 1/n dot so far as the previous printed data is no new line and lately printed data is a new line. CONSTITUTION:When data is inputted to a control circuit 2, the control circuit 2 judges whether said data is a printing start code and, when the printing start code is judged, judges whether the previous printing data accompanies a new line. If the previous printed data accompanies no new line and the lately printed data accompanies the new line, the control circuit 2 controls a motor driver 5 to perform operation for shifting a printing position by a minute distance and outputs a signal to said motor driver 5 to rotate a carrier motor 6 so as to shift the printing position by 1/n dot and outputs printing data to a head driver 3 to perform printing corresponding to one line. The distance shifting a dot is set to 1/n the width of the dot and, by selecting a proper value of (n), a desired emphasis degree can be obtained.

Description

[Detailed Description of the Invention] [Technical Field] "Unexploited paper" is related to the printing method, especially any printer
'+1. '■SeQlto&+i Machi・1 and Fumomo's death are related to each other's twists.

[Prior art]

Conventionally, printers equipped with the function of 92 double stroke or emphasis have been put into practical use, but the command codes for double stroke, etc. differ depending on the manufacturer.

Therefore, since the Azorikeshi = I7 program for computer word processors, etc., which are commonly used in personal computers, specifies multi-print printers, double printing means printing the same print data twice (the first time is without a line break). ) is realized by sending.

Particularly in wire-dot or ink-jet printers, the ink spreads on the paper, so double striking can reduce printing noise to some extent.

However, thermal glinters, thermal transfers, and the like have the disadvantage that, because the colored portion or ink does not diffuse, sufficient printing cannot be achieved even with double striking or several overlapping strikes.

[Purpose of the invention]

"Unexploited" was created in view of the above conventional drawbacks,
The purpose is to provide a printing method that can print clearly and strongly by main printing, regardless of whether it is a thermal method, a wire dot method, or an inkjet method.

[Summary of the invention]

In order to achieve the above object, the printing method according to the present invention is limited to cases where the previous print data is a non-line feed and the current print data is a line feed, and the current print data is printed by 1/n dots. It is characterized by printing in a shifted manner.

[Embodiments of the invention]

Embodiments of the present invention will be described in detail below with reference to Figure III.

FIG. 1 is a block diagram of a printer that employs one embodiment of the printing method according to the present invention.

In the same figure, postcomputer 1 and printer +l
What is i control circuit 2? Connect, print data and tti control circuit 1 from host computer 1) 1 control circuit 2 to host computer 1
Based on the input data from the printer, print data is output to the head driver 3, and the head driver 3 operates the print head 4 according to the print data. Furthermore, the control circuit 2
The motor driver 5 is i-controlled to control the carrier motor 6 that moves the carriage on which the print head 4 is mounted, and the filter paper feed shim motor 7 that drives the paper feed mechanism such as the paper feed shi roller or the I/'i platen. Operate over time.

The carrier motor 6 and the paper feed motor 7 are stepping motors, and their rotational angles and speeds are controlled with high precision by the number and frequency of the signals output from the control circuit 2.

The operation of this embodiment of the printer configured as described above will be described in detail with reference to the drawings. FIG. 2 is a flowchart of this embodiment, FIG. 3 is an explanatory diagram of input data input from the host computer 1, and FIG. 4 is an explanatory diagram of printing results.

In FIG. 2, when data is input to the host computer I control circuit 2 (STI), the control circuit 2 determines whether the data is a print start code (ST2).

If it is not a print start code (No in ST2), input the next data (STI), and if it is a print start code (ygs in ST2), determine whether the previous print data 1a was accompanied by a line feed (ST3) ).

If the previous print data did not include a line feed (S

1f, perform a shifting operation. However, the direction of the shift may be selected in advance by installing the switch 11 in the control circuit 2, or by setting the switch 11 on a switch panel or the like to determine the direction. In any case, the 11R1 control circuit 2 cuts off the selected direction 2i-1J (ST5) and continues its operation. Here, the case of shifting in the horizontal direction (A in ST5) continues, the control circuit 2 outputs a signal to the motor driver 5,
The carrier motor 6 is rotated so that the printing position is shifted by 1/n dot (S'T'6). Then, the print data is output to the head driver 3, the print head 4 is energized, and the carrier motor 6 is rotated at a predetermined speed to print one line (ST7).

When printing for one line is completed, the carriage is returned to the starting position by the carrier motor 6 (5T8), and data for the next line is input (ST1). The same applies below. however,
If the previous print data included a line feed (YES in ST3), the paper feed motor 7 was driven to perform a line feed (
After ST9), a printing operation is performed (ST7). still,
If the current print data does not include a line feed (ST
In case of No. 4), one printing operation is performed without shifting the printing position (ST7).

FIG. 3 shows the correspondence between input data D and its printing results in this embodiment. However, C/R in the figure represents a carriage return command, and C/R represents a line feed command.

In the same figure, since the print mode of the rlIJ print data DI does not involve a line feed (L/F), and the print mode of the current print data D2 involves a line feed, the current print data 1) and 2 are the previous print data. superimposed on the printing result of , and 1/n
Printing is performed with a shift of t't. Therefore, two characters are printed twice (a printing result in which ABJ is boldly emphasized) is obtained.

are doing. In other words, dot R1 has been completely printed by the previous printing, and by printing this time, dot R1 has been printed by 1/2.
DR) R2 is printed at position 11'i, shifted horizontally by a dot.

In this way, by shifting the printing position by a small distance to 1i-, the sound of the letters can be greatly emphasized, but in simple nail printing like Takumi's, it is possible to emphasize the letters as shown in Figure 5. ,I-
Can not do it.

In addition, as shown in FIG. 6, the previous print data D1
If this is accompanied by a line feed, the current print data D2 is printed on the next line after the nl'' printing results.

Furthermore, as shown in FIG. 7(,), even if the print data D1 and D2 without a line feed are consecutive, the printing position does not shift until the print data D3 with a line feed is input. A printing result as shown in b) is obtained.

In other words, R1 and R2 are printed overlapping each other, and R1 and R2 are printed overlapping each other.
R3 is printed with a 1/3 dot shift in the horizontal direction, resulting in a strongly emphasized character (in this case, a colon "=").

Incidentally, the direction of the shift is not limited to the horizontal direction, but may be the vertical direction (B of Sr1) or the diagonal direction (C of Sr1), as shown in FIG. When shifting the dots in the vertical direction, it is best to rotate the paper feed shimotor 7 by a predetermined angle to feed the paper minutely (STIO).

Furthermore, when the dots are to be shifted diagonally, this can be achieved by driving the carrier motor 6 and the air blower motor 7 (S''T11 and STI2).

Furthermore, by combining ST 6 tST 10 to 5T12, the dot can be enlarged both horizontally and vertically.
Real JJi easily from the flowchart in the figure! j can.

Further, the distance by which the dots are shifted is set to 17n, which is the width of the dots, and by selecting a reasonable value of n, a desired degree of emphasis can be achieved.

It is obvious that the printing method according to the present invention can also be applied to type printers.

[Effect of ψ]

As explained in detail above, the printing force method according to the present invention can print by shifting the printing dots by a minute distance -W, and the shifting distance and direction f3 can be selected. It has the great effect of being able to print multiple times and applying as much pressure as necessary to print.
