Abstract

PURPOSE:To decrease the capacity of a memory by storing an optional one of function codes in a memory together with a printing data as a repeated printing instruction, when executing the printing. CONSTITUTION:After a printer has read out a data of a pattern A, when a repeated printing instruction 1 is read out, the printer executes read-out again from an address 3 in which the first data of the pattern A stored in addresses 4012, 4013 is stored, namely, an address 4000. When the printer reads out a data of a pattern B, and a repeated printing instruction 4 is read out, read-out is executed again from an address 4016. In such a way, it becomes unnecessary to store all the data that are printed by a self-printer.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a print data storage method, and particularly to a storage method for storing print data necessary for a printer to perform self-printing in a memory inside the printer.

[Conventional technology]

Conventionally, when storing print data in a memory inside the printer in order for the printer to perform self-printing, all of the print data to be printed by self-printing had to be stored in the order in which they were printed.

For example, when printing a print pattern as shown in FIG. 3 by self-printing, the print data had to be stored in a memory inside the printer as shown in FIG.

[Problem that the invention seeks to solve]

In this way, according to the conventional memory method, all the data printed by self-printing must be memorized in the order in which they are printed. There was also a problem in that the capacity of the memory for storing print data had to be increased.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the conventional method and to provide a print data storage method that requires less memory capacity.

[Means for solving problems]

According to the present invention, when a printer stores print data in its memory in order to perform self-printing, one of the funxy codes that the printer does not need to use when printing is repeatedly used as a print command. means for storing in the memory together with the print data to be stored; means for storing the number of repetitions following the repeat printing command; and means for storing the address of the memory where the first data of the print pattern to be repeatedly printed is stored. A print data storage method is obtained which is characterized by having the following.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

Figure 1 is a memory map when the storage method of the present invention is applied to the print pattern of Figure 3;

Note that when the printer performs self-printing, it is assumed that the printer reads data from address 4000 and prints it.

In addition, in this embodiment, the DC2 code (1
2H) is used.

Addresses 4000 to 400F store the data of the printing pattern person.
A repeat printing command 1 for K is stored. After the printer reads the pattern person data, <When the printer reads the return print command 1, the printer prints the data at addresses 4012 and 4.
Reading is performed again from address 3, which is address 94000, where the first data of the pattern person stored at address 013 is stored. After reading the data of pattern A two times for the number of repetitions 2 of pattern A stored at address 4011, the printer d4014
The OR code (ODn) of the address and the LF code (OAg) of address 4015 are read out, and printing of the first line in FIG. 3 is completed.

Data of print pattern B is stored at addresses 4016 to 4035, and repeat printing command 4 for pattern B is stored at address 4038. The printer reads the data of pattern B and then prints the data at address 4036.
After reading the R code and the LF code at address 4037 and finishing printing the second line in FIG.
Reading is performed again from the address indicated by address 03B or address fi4016. In this case, since the OR code and the L k' code are stored before the repeat printing command 4, the number of lines indicated by the number of repetitions 5 of pattern B stored at address 4037 is printed. Three lines of pattern Bi will be printed.

With the above steps, all the printing patterns shown in Figure 3 have been printed.If you memorize the printing patterns shown in Figure 3 using the conventional memorization method, the numbers 4000 to 4000 will be printed as shown in Figure 2.
87 address, that is, a memory capacity of 136 bytes, according to this embodiment, it is understood that the memory capacity of addresses 4000 to 403B, i.e., 1) 60 bytes, is sufficient.

〔Effect of the invention〕

As explained above, the present invention enables self-printing by repeatedly storing any one of the seven code codes that are necessary for printing in the memory together with print data as a print command. Since it is no longer necessary to store all of the data to be printed in the order in which it is to be printed, there is an effect that the memory capacity can be reduced compared to the conventional method.

[Brief explanation of drawings]

FIG. 1 is an example of a memory map when the present invention is applied to the print pattern shown in FIG. 3, FIG. 2 is a memory map when the conventional memorization method is applied to the print pattern shown in FIG. 3, and FIG. This is an example of a l printing pattern. l...<Return printing command for pattern AK,

Claims (1)

[Claims] If the printer stores print data in its memory for self-printing, the print data should be stored as a repeat print command of one of the function codes that the printer does not need to use when printing. It is characterized by comprising means for storing the same in the memory, means for storing the number of repetitions following the repeat printing command, and means for storing an address of the memory storing the first data of the printing pattern to be repeatedly printed. Print data storage method.
