Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a line / column control system
Exhibition of application programs created for
Open and print the print data it produces to the printer.
That relates to a data processing device, in particular, application programs, without changing the program configuration, a data processing apparatus that enable and execute printing of the printer take any point addressing scheme.

In recent years, printers adopting an arbitrary point address system have come to be used because various printing forms are possible. The printer of the arbitrary point address system receives print data describing an arbitrary position on a printing paper surface and processes the print data so as to print the print data at the designated print position. When such an arbitrary point address printer is installed, it is necessary to prevent the application program (user program) that has been used up to now from being changed.

EXAMPLES The present invention will be described in detail below with reference to examples. FIG. 2 shows an example of a processing flow executed by the calculation unit 15 included in the output control unit 14 described with reference to FIG. 1, and FIG. 3 includes an addition unit 16 and special features included in the output control unit 14 described with reference to FIG.
An example of a processing flow executed by a constant unit 16a (hereinafter abbreviated as an adding unit 16) is illustrated. Next, the present invention will be described in detail according to these two processing flows.

When the calculation unit 15 of the output control unit 14 receives the print request for the print data from the data processing unit 10, the calculation unit 15 of FIG.
First, as shown in the processing flow of FIG.
Then, the print start origin information (X _0, Y ₀ ) designated by the job control unit 13 and stored in the output data file 11 is read. Print start origin information (X _0, Y ₀ ) read at this time
Defines the print start origin position on the printing paper, as shown in FIG. Subsequently, in step 2, the calculation unit 15 obtains the print line spacing information designated by the parameter information from the line spacing information library 12 according to the parameter information designated by the job control unit 13 stored in the output data file 11. Read. As shown in FIG. 4, the print line interval information read at this time has entries for the number of lines of one page of printing paper, and each entry defines a line interval such as 6 lines per inch. The interval display value y _i (i = 1 to n) is registered and managed. The X coordinate value X ₀ of the print start origin information (X _0, Y ₀ ) read in step 1 is notified to the addition unit 16.

In this way, the print start origin information (X _0,
When Y ₀ ) and the print line interval information (y _i ) are read in, the calculation unit 15 sets “1” to the variable i managed by itself in step 3, and then in step 4,

[0015]

[Equation 1]

According to the above, the print start position Y ₁ of the first line is calculated. Then, subsequently, in step 5, the calculated print start position Y ₁ of the first line is set to the line / line shown in FIG.
It is stored in the first entry of the coordinate correspondence table 18. The print start position Y ₁ of the first line calculated according to the formula ₁ is calculated assuming that the line spacing display value y _i represents the number of lines per inch (25.4 mm). Therefore, assuming this, as shown in FIG.
Since the line spacing value of the first line becomes "25.4 / y ₁ " correspondingly, with the print start origin Y ₀ as the reference, the middle of this line spacing value is set as the print start position Y ₁ of the first line. It is calculated.

Subsequently, the calculation section 15 increments the variable value of the variable i by 1 in step 6, and in the subsequent step 7, the variable i
It is determined whether the variable value of has become "n + 1". That is, it is determined whether or not the processing has been completed for all the line spacing display values y _{i included in the} print line spacing information read from the line spacing information library 12. If it is determined in step 7 that the unprocessed line spacing display value y _i remains, the process proceeds to step 8

[0018]

[Equation 2]

According to the above, the printing start position Y of the i-th line_iTo
calculate. Then, in the following step 9, the calculated first
Print start position Y on line i_iIs the row / coordinate shown in FIG.
After storing it in the i-th entry of the correspondence table 18,
Process to return to Step 6. Calculate according to this formula
Print start position Y of the i-th row that is issued_iIs the line spacing display value
y_iRepresents the number of lines per inch (25.4 mm)
It is calculated assuming that
Then, as shown in FIG. 5B, the line spacing of the (i−1) th line
Value and the line spacing value of the i-th line are "25.4 / y"_i-1"
And "25.4 / y _i", So start printing on line (i-1)
Position Y_i-1The average value of these two line spacing values based on
Is the print start position Y of the i-th line_iIs calculated as
You.

In this way, by repeating the processing of steps 6 to 9 to calculate all of the printing start positions Y _i of the i-th row calculated by the equation (2), The unit 15 ends the process according to the determination in step 7. By the processing executed by the calculation unit 15, as shown in FIG. 4, the printing processing of the printer 2 of the arbitrary point address method is performed on the n entries prepared as one page of the printing paper of the row / coordinate correspondence table 18. The print start position Y _{i in the} Y direction, which is necessary to execute the above, is registered.

When the entry processing of the row / coordinate correspondence table 18 by the calculation unit 15 is completed, the addition unit 16 of the output control unit 14
As shown in the processing flow of FIG. 3, first, in step 10, the variable i managed by itself is set to “1”,
Then, in step 11, the top data of the print data is read from the output data file 11. Then, in the following step 12, the print start position Y ₁ of the first line is read from the first entry of the line / coordinate correspondence table 18, and in the following step 13, the read print start position of the first line is read. According to Y ₁ , the print start position information (X ₀ , Y ₁ ) is added to the head data of the print data read in step 11, and the result is passed to the sending unit 17.

Subsequently, the adding unit 16 is step 14
The variable value of the variable i is incremented by one, and in the following step 15, it is determined whether or not the variable value of the variable i has become “n + 1”. That is, it is determined whether or not the processing up to the bottom line of the printing paper has been completed. By the judgment of this step 15,
When it is determined that the process up to the bottom line of the printing paper has been completed, the process returns to step 10. On the other hand, when it is determined that the processing up to the bottom line of the printing paper has not been completed, the process proceeds to step 16 and the output data file 11
Read the next data of the print data from the following step 1
If it is determined in step 7 that there is no next data to be read, the process ends. On the other hand, when it is confirmed in step 17 that the next data is read in step 16, the process proceeds to step 18 and the i-th row / coordinate correspondence table 18
The print start position Y _i of the i-th row is read from the entry, and in the following step 19, print start position information is added to the print data read in step 16 according to the read print start position Y _i of the i-th row. (X ₀ , Y _i ) is added and passed to the sending means 17, and processing is returned to step 14.

In this way, the adding unit 16 repeatedly executes the processing of Step 14 to Step 19 to correspond to the print data read from the output data file 11 as shown in FIG. The print start position information (X ₀ , Y _i ) is added and passed to the sending means 17.

According to the processing of the adding section 16, the sending section 1
By sending the print data to which the print start position information is added to the printer 7, the print processing 7 is realized by the printer 2 of the arbitrary point address method. As a result, the job control unit 13 can control the print processing in the printer 2 of the arbitrary point address system only by issuing the same print information when it is issued to the printer of the line / digit control system. From now on, the printer 2 of the arbitrary point address system can be connected to the host system 1 without changing the program description of the data processing unit 10.
