Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to control of paper width and font size of a printer which is an output device around a computer.

[0002]

2. Description of the Related Art Conventionally, a printer, which is an output device around a computer, is changed to printing paper having a short print width as shown in FIG. 4, and print data output from a host computer is changed according to the print width. , I was adjusting the paper width.

[0003]

However, according to the above-mentioned prior art, there is a problem in that the printing characters of a short paper width are missing only by mechanically replacing the printing paper with a short paper width. . Therefore, an object of the present invention is to perform printing without loss of printing even when the printing paper is replaced with a printing paper having a short printing width.

[0004]

In order to solve the above problems, the first invention has a function of detecting the paper width and a function of selecting a font size according to the paper width of the printing paper. Is a printer.

A second aspect of the present invention is provided with a function for registering external character data having different sizes according to the font size,
A printer having a function of selecting an external character size according to the paper width of a printing paper.

A third aspect of the invention is a printer characterized by being provided with a function of registering bit images of different sizes according to the font size and a function of selecting bit images according to the paper width of the printing paper. Is.

A fourth aspect of the invention is characterized in that the printing position of the ruled line is calculated and automatically adjusted according to the paper width of the printing paper.

BEST MODE FOR CARRYING OUT THE INVENTION In FIG. 1, print data input from a host computer 14 to an input terminal 8 of a control circuit 1 is converted into a character pattern by the control circuit 1 by referring to font data 2 and 3 and external character data 4 and 5. Convert and print head 1
In the printer that controls the printing unit 10 including the sheet feeding mechanism 12 and the paper feeding mechanism 12 to print on the printing paper 13, the control circuit 1 has a function of detecting the paper width of the printing paper 13 by the sensor 9 that detects the paper width, Different 24 dot font data 2 and 16 dot font data 3, 24 dot external character data 4 and 16 dot external character data 5, 24 dot bit image 6 and 16 dot bit image 7
have. The 24-dot external character data 4, 16-dot external character data 5, 24-dot bit image 6, and 16-dot bit image 7 can be registered by the host computer 14.

In the printer having the above-described structure, the host computer 14 has a 112 mm printing paper 1 as shown in FIG.
24A external character data 4 for 3A, 4A external character and 24D bit image 6 for bit image 6A, and 80mm printing paper 13B for 16D external character data 5 for external character 5A and 16 dot bit image 7 as shown in FIG. The bit image 7A is registered in advance.

Conventionally, there was a printer such as a label printer which can handle different paper widths, but as shown in FIG.
The host computer 14 is provided on the 12 mm printing paper 13A.
Output 112 mm print data 15A from the host computer 14 to 80 mm when printing 80 mm print paper 13A.
The print width was adjusted by outputting 0 mm print data 15B. In the printer as described above, if the host computer 14 mistakenly outputs the 112 mm print data 15A even though the 80 mm print paper 13B is set in the printer, a part of the print is lost as shown in FIG. There was a problem. In such a state, the print head 1
In some cases, stress may be applied to the paper feed mechanism 12 and the paper feed mechanism 12.

Therefore, in the present invention, the control circuit 1 determines the paper width detected by the sensor 9 for detecting the paper width.
For 2 mm printing paper 13A, refer to 24 dot font 2, 24 dot external character data 5, 24 dot bit image 7 and print a slip as shown in FIG.
When it is determined that the printing paper 13B is No. 3, the 16-dot font 3, the 16-dot external character data 5, and the 16-dot bit image 7 are referenced to print the slip as shown in FIG. In addition, the control circuit 1 prints a ruled line at 112 m
80 mm compared to the ruled line 16A of the printing paper 13A of m
The printing position of the printing paper 13B is printed at the position of ⅔, and the position is adjusted according to the font size as the ruled line 16B in FIG.

As described above, in the present invention, the printer can detect the paper width of the print paper 13 and adjust the print size according to the paper width.

The paper width and the font size in this embodiment are only examples, and it is possible to combine different font sizes with the same paper width, and other font sizes and paper widths of other printing papers are the same.

[0014]

As described above, according to the present invention, since the width of the printing paper is detected and the size of the printing character is automatically adjusted, the printing is lost even if the printing paper having a short printing width is replaced. It can be printed without.
