Abstract

PURPOSE:To express that a collapse character pattern is used, to easily identify a printing quality by a method wherein an auxiliary memory for storing a collapse pattern of a generated character pattern is provided, and pixel information stored in a pixel memory means is outputted based on the information stored in the auxiliary memory. CONSTITUTION:Previously, a character pattern in a font cash memory 4 is developed on an output coordinate position in a bit map memory 3 on the basis of input information, and the coordinate of a collapse character and the type of half-tone dot meshing of the flat character are stored on an auxiliary memory 5. In the presence of an output command, whether it instructs the output of a collapse character pattern is checked, and whether it is a character pattern the type of half-tone dot meshing of which has been stored in the auxiliary memory 5 is checked. As a result, if the type of half-tone dot meshing is present, the half-tone dot meshing is applied to the coordinate of the bit map memory 3 on which the collapse character pattern has been developed. Then, an output part 6 is started, and the information per pixel in the bit map memory 3 is outputted. In this manner, a collapse character pattern is applied with a half-tone dot meshing, whereby the used position can be easily identified.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printing device, and particularly to a printing device that prints by enlarging or reducing character patterns.

[Prior Art] Conventionally, this type of device is configured to generate and correct a pattern based on a predetermined character pattern when enlarging or reducing a character pattern of characters to be printed.

[Problem to be solved by the invention] However, in the above conventional example, when making an amendment, for example,
When reducing a character pattern as shown at 30 in Figure 3, if the reduction rate is 1/4, the pattern shown at 31 will be generated, but if it becomes 1/7, a collapsed pattern as shown at 32 will be generated. The problem was that the correction could not be completed and the character pattern was printed as it was. Additionally, a character pattern with the closest size that can be corrected is generated and printed.

The present invention was made to solve the above problems, and
It is an object of the present invention to provide a printing device that can express a crushed character pattern and easily check the print quality.

[Means and operations for solving the problems] In order to achieve the above object, the printing apparatus of the present invention has the following configuration.

That is, in a printing device that can change the size of character patterns,
an input means for inputting print information; a generation means for generating a character pattern according to the print information from the input means; and a storage means for storing if the character pattern generated by the generation means is a flattened pattern. , a font storage means for storing the character pattern in the generation means, a pixel storage means for expanding and storing the character pattern stored in the font storage means into pixel information, and pixel information stored in the pixel storage means and the pixel information stored in the pixel storage means and the and output means for outputting based on the information stored in the storage means.

[Embodiment] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Description of Configuration (Fig. 1)> Fig. 1 is a block diagram showing the configuration of a printing apparatus in this embodiment. In the figure, 1 is an input unit for inputting printing information from a host computer (not shown), etc., and 2 is an input unit 1.
This is a control unit that judges input information from and controls character patterns, pixel-by-pixel information, etc. The control unit 2 includes a CPU that executes control to be described later, a ROM that stores a processing program for the CPU, and a RAM that is used as a work area when executing processes. 3 is a bitmap memory that stores output information in pixel units; 4 is a font cache memory that stores character patterns; 4 is a font cache memory that stores character patterns; An auxiliary memory stores the coordinates and output information when outputting using a collapsed character pattern, and the type of shading indicating the collapsed state, and 6 is an output unit that outputs the output information.

<Description of Processing Procedure (FIG. 2)> Next, the processing procedure in this embodiment will be explained below according to the flowchart shown in FIG.

First, in step 5201, input information including various commands is received from the host computer (not shown) through the input unit 1, and the process proceeds to step 5202, where the input information is used to enlarge, reduce, etc. the character pattern. Determine whether it is a font creation command. As a result, if it is a font creation command, the process advances to step 5203, where a character pattern font is created from the input information, expanded into the font cache memory 4, and the process ends. For example, if the characters are reduced, the character pattern may be collapsed as shown in 32 in FIG. .

However, if it is not a font formation command, step 52
The process proceeds to step 04, and it is determined whether or not it is output data. If it is output data, in step 5205, the character pattern in the font cache memory 4 is expanded to the output coordinate position in the bitmap memory 3 based on the input information. Then, in step 5206, it is determined whether or not the developed output data is a collapsed character pattern, and if it is a collapsed character pattern, the process advances to step 5207. This step 5207 is a process for expressing crushed characters by shading. As a specific process, in this embodiment, the coordinates of the collapsed character and the type of shading thereof are stored in the auxiliary memory 5, and the process ends. However, if it is a normal character, it ends as is.

On the other hand, in step 5204, if it is not output data, the process advances to step 5208, and it is checked whether the human power information is an output command. As a result, if it is not an output command, the process ends, but if it is an output command, step 5
In step 209, it is checked whether a collapsed character pattern is output. The check here is the step 5207 described above.
This is a process of checking whether the type of shading is the character pattern stored in the auxiliary memory 5. As a result, if there is a type of shading, the process advances to step 5210, and shading is added to the coordinates of the bitmap memory 3 where the collapsed character pattern has been developed. Then, the output section 6 is activated to output information in pixel units of the bitmap memory 3.

As described above, according to this embodiment, by printing the crushed character pattern with shading, it is possible to easily confirm the location where the character pattern has been used, and also to easily recognize the printing quality.

In this embodiment, the use of a collapsed character pattern is expressed by shading processing, but the following processing may also be considered.

l) Output with different colors.

2) Output a mark outside the output area at the end of the line where the character pattern exists.

3) If there are two or more paper sources such as printing devices,
One side outputs normal output, and the other paper feed unit outputs marks at the coordinates of the collapsed character pattern on a transparent output medium.
To enable judgment by superimposing two outputs.

[Effects of the Invention] As described above, according to the present invention, a collapsed character pattern can be expressed as such, and the print quality can be easily confirmed.
