Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing method for printing with a character size designated according to a character code from a host system.

When printing with a printer according to a character code from a host system, the character size may be designated by a control code, or the character size may be designated separately from outside. Therefore, regardless of which designation method is used, it is desired to perform printing uniformly with an arbitrary character size without performing an external conversion work or the like.

[0003]

2. Description of the Related Art Conventionally, between a host computer as a host system and a printer, printing is performed by the printer according to data from the host computer. This data includes a control code and a character code in the character string data. The control code includes the character size and print start position (X
(Y coordinate), typeface, length of character string, etc. are included. That is, of the data sent from the host computer, the character pattern corresponding to the character code after the control code is printed by the printer by switching the character size according to the control code.

However, since the character size is switched by the control code, only the predetermined character size cannot be switched on the printer side, and a character of an arbitrary size other than the predetermined character cannot be output.

Therefore, instead of the control code, another method of sending another command of size order from the host computer or other external system to specify the character size and output it in an arbitrary character size by the printer is also possible. is there.

[0006]

However, a printer whose character size is arbitrarily designated by an external system cannot accept data for switching the character size by a control code. Therefore, when the control code data is received, it is necessary to remove the control code from the data and convert the character size to be the same as the data from the external system. There is a problem of becoming.

Therefore, the present invention has been made in view of the above problems, and an object thereof is to provide a printing method for designating a character size without converting data having a control code.

[0008]

According to the character code of the data for designating a character string to be printed with the designated character size by the data designating an arbitrary character size sent from the host system, the printing device is provided. In the printing method for performing printing by the
The character size corresponding to the control code including the information for switching the character size which is uniformly set in advance is registered in the table, and the data designating the character string having the control code is sent from the host system to the printing apparatus. In this case, the character size corresponding to the control code is determined and held on the table, and the character pattern held corresponding to the character code of the data designating the character string is searched for and held. It is solved by printing with different character size.

[0009]

As described above, the printing apparatus has the table in which the character size corresponding to the control code is registered. Therefore, when the data including the control code is sent from the host system, the character size corresponding to the control code is determined and held on the table. Then, the character pattern held corresponding to the character code of the data is searched for and printing is performed with the held character size.

That is, the data having the control code is
The data is processed as data designating an arbitrary character size without switching the character size by the control code.

As a result, the character size can be specified without converting the data having the control code.

Next, FIG. 2 shows a diagram for explaining the data processing of the present invention, and FIGS. 3 and 4 show a diagram for explaining the operation of the present invention, and FIGS. The operation will be described with reference to FIGS.

In the printing method of the present invention, as a data method sent from the channel 1a of the host computer 1 to the I / O 3 of the printing apparatus 2, a control code method for sending control code data and a size order for sending size order data. There is a method.

As shown in FIG. 2A, the control code data includes a control command a, a print command of a character string order,
b, ... And character string codes A, B, C, ...
Is added. In this case, the control code a,
b, ... Includes information such as character size, typeface, character string length, and print start position of XY coordinates.

The size order data is shown in FIG.
As shown in, a size order command and a character string order print command are divided. The size order is set with the information of the size order method 1 or the control code method 0 as the data method switching order as shown in FIG. 2D, and also as the character size designation order as shown in FIG. 2E. Character sizes X and Y are set. Also, the character string order is the start coordinate code x ₀ ,
y ₀ and character codes A, B, C, ... Are added.

Now, channel 1 of the host computer 1
When either the control code data or the size order data is sent to the I / O 3 of the printer 2 by a, it is determined whether or not the size order is set as shown in FIG. 3 (step (abbreviated as “ST”). ) 1). If it is a size order, “1” is stored as the size order method, and if it is not the size order, “0” is stored in the character size storage area of the CPU 4 (ST2, ST3, (FIG. 2 (D)). .
In the case of the size order method, the character sizes X and Y are stored and held in the character size storage area of the CPU 4 by the character size designation order as shown in FIG.
4).

Next, in the process for printing, as shown in FIG. 4, when the printer 2 receives data, it is stored in the character size storage area of the CPU 4 whether or not the data system is the control code system. Judgment is made by the signals "0" and "1" (ST10). If the data type is the control code method, it is determined whether the control code is present (ST11), if present, control over size table 5 _A in the memory 5 the code a, b, c, corresponding to ... characters The size is determined, and the character sizes x ₁ , y ₁ , x ₂ , y ₂ , x ₃ , y ₃ , ... Are stored in the character size storage area of the CPU 4 in ST4 of FIG. ₃ (CT135.

As a result, the control code data can be handled as if it were the size order data.

Therefore, in the memory 5, a character pattern corresponding to the character size stored in the character size storage area of the CPU 4 is selected from the character pattern storage area 5 _B (ST1
4), the control code a of the character string order shown in FIG.
b, ... after the additional character codes A, B, C, ... the character patterns corresponding to the search from the character pattern storage area 5 _c in (ST15). These processes are repeated from ST12 to ST15 until all character string data is completed (ST
16).

In ST12, for example, when the character code B is processed after the character pattern corresponding to the character code A is searched, the control code does not exist, and the character size is the same as that of the character code A immediately. The process moves to ST15 where the character pattern corresponding to the character code B is inspected.

In ST11, if the data method is size order data (FIG. 2B), the character size corresponds to the character size already stored in the character size storage area of the CPU 4 in ST4 of FIG. The character pattern to be selected is selected in the character pattern storage area 5 _B of the memory 5 (S
T17), and shifts to ST15.

Regardless of the control code method or the size order method, all the retrieved character patterns (dot patterns) are sequentially expanded to the positions corresponding to the drawing position designation in the character data on the bit map memory 6. Then, the process ends (ST18).

In this way, the hit map memory 6
When the document for one page is developed, the contents of the bit map memory 6 are sequentially read out by the control of the CPU 4 and the printer 7 prints. As a result, it is possible to print the data having the control code related to the character size with the specified character size without performing the conversion.

[0026]

As described above, according to the present invention, the character size corresponding to the control code is registered in advance in the table, and the character size corresponding to the control code is determined and held in the table. By printing the character pattern corresponding to the character code in the character size, the character size can be specified without converting the data having the control code related to the character size, and the control data can be avoided without complicating the processing. The method can be processed by one printing device as in the size order method.
