Abstract

PURPOSE:To make it possible to print a desired portion of inputed data, by checking whether a specified character pattern is present, not on a record basis but on a line basis and a colum basis. CONSTITUTION:Data inputted from a console 4 is stored in an area of a RAM 7, a value indicative of the type of printing is set into a printing type flag F, a specified line into a line register L, a specified column into a column register D, and a specified pattern into a pattern buffer B. Next, recording data is received, and a one-page amount of the data is set into a data page buffer (DB) 8. It is checked whether the DB 8 is empty. When the DB 8 is not empty and the pattern indicated by the data in B is present in the range starting from a position specified by the data in L and D, it is checked whether the value in F is 0 (printing only the specified line). When the value in F is 0, the L-th line in the DB 8 is expanded into dot images in a PB 10, and the content of the PB 10 is printed. When the value in F is not 0, the content of the DB 8 is expanded into dot images in the PB 10, and the content of the PB 10 is printed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to printing devices, and particularly to page printers.

[Prior Art 1] Conventionally, this type of apparatus has had a function of printing only records (basic units of data) that include character patterns specified by an operator among print data.

[Problem to be Solved by the Invention 1] However, in the above-mentioned conventional example, only records containing a specified character pattern are printed out, and therefore, there are the following drawbacks.

■Cannot be used when trying to print out the entire page including the instruction character pattern.

■If there are records that are not needed even if they contain the specified character pattern, and if you print out those records, you will need to cut and paste them later, so you should save and manage the printed recording paper as it is. cannot be used for

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned drawbacks and to provide a printing device that can print out a desired portion of manually inputted data.

[Means for Solving the Problems] In order to achieve such an object, the present invention provides human-powered means for manually inputting instruction information regarding printing, recording means for storing the manually-operated instruction information, and printing data. and a developing means that reads instruction information from the storage means and develops the print data into dots according to the instruction information.

[Function] According to the present invention, by determining whether or not a specified character pattern exists not on a record-by-record basis but on a line and column-by-column basis, only necessary lines can be printed and only necessary pages can be marked 1f. Is it something to do?

[Example 1 Hereinafter, the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1, the printing apparatus according to the present invention includes a human-powered means 101 for manually inputting instruction information regarding printing, a key f and Q means 102 for recording the manually-entered instruction information, and print data. The printing apparatus includes a reading means 103 for reading, and a developing means 104 for reading the instruction information from the storage means 102 and developing the print data into dots.

FIG. 2 shows the configuration of a printing apparatus according to an embodiment of the present invention. Here, 1 is a data generation source 7 composed of, for example, a host computer, and outputs data to a human interface section 3 which is a component of the printer 2. The printer section 2 has components indicated by reference numbers 3 to 12.

4 is a console, which manually inputs information for actual printout. Reference numeral 5 denotes a CPU (central processing unit), which performs overall control of the printer section 2. 6 is ROM
(read-only memory), and stores a control program according to the processing procedure shown in the flowchart of FIG.

7 is RAM (random access memory), C
Various data sent from the PU 5, flag information, calculation results, etc. are stored. The RAM 7 has areas for a line register (L), a 1-digit register (D), a pattern buffer (B), and a print type flag (F).

The line register (L) stores a designated line instructed from the console 4. The digit register (D) stores the specified digit specified from the console 4. The pattern buffer (B) stores the specified pattern, and the flag (F) records the type of printing. Referring to these, the CPt 15 develops data manually input from the data generation source 1 via the human interface section 3 into an output page buffer 10, which will be described later.

A data page buffer 8 stores data such as character codes sent from the CPIJ 5 in page units. A character pattern generating section 9 converts the character code stored in the data page buffer 8 into a character pattern and outputs it to the output page buffer IO.

Reference numeral 11 denotes an output interface section, which generates a video signal according to the dot information output from the output page buffer 10. Reference numeral 12 denotes an output device, which receives the video signal 18 generated at the output interface section and actually outputs an image.

FIG. 3 is a flowchart illustrating a print control procedure according to an embodiment of the present invention. From step 51 to step S4, the information input manually from the console 4 is stored in the RAM 7 area. A value indicating the print type in step S1 (in this embodiment, 0...Prints only the lines that include the specified pattern starting from the specified number of digits, 1...The specified pattern starts from the specified line and digit) Print out the page containing f:u 5E
The IJ flag (F) is set, the specified line is set in the row register (L) in step S2, the specified tti is set in the digit register (D) in step S3, and the specified pattern is stored in the pattern buffer (B) in step S4.
Set to .

Next, the process moves to step S5, where data is received and one page's worth of data is set in the output page buffer (DB) 8. Then, in step S6, it is determined whether the DB8 is empty.

If the determination in step S6 is YES, there is no data to be output, so the process moves to step 512, and it is determined whether the output page buffer (PB) 10 is empty.

If the determination in step S12 is YES, the process ends; if the determination is NO, in step 513, the PBIO
Print the contents and exit.

If the determination in step S6 is NO, step S7
Then, it is determined whether the pattern indicated by CO exists from the positions specified by L and D in steps S2 and S3. If the determination in step S7 is No, the process returns to step S5. The determination in step S7 is Y.
In the case of ES, the process moves to step S8 and it is determined whether F in step S1 is 0 or not.

Then, in step S9, the next row of DB8 is transferred to PBIO.
Expand the dots. Next, the process moves to step 510, and it is determined whether or not the PBIO is full as a result of the expansion. Step 5
If the determination in step S10 is YES, the contents of PBIO are printed in step Sll and the process returns to step S5. If the determination in step S10 is NO, step S5
Return to

If the determination in step S8 is NO, step 51
4, the contents of DB8 are expanded into PBIO, and in step 515, the contents of PBIO are printed, and the process returns to step S5.

FIG. 4 shows the results printed by the control procedure as described above. In FIG. 4, the numbers (A) to (F) indicate examples in which human data is printed as is. The command from console 4 is “COMPAN” from 01 line 3 digits.
When printing a page containing "Y A", print (A) and (E).

Instructions from console 4 are ■Print the line containing “ID3” from line 5, column 1 If so, print (G).

As explained above, in this embodiment, there is one set of areas for seven columns of rows and patterns in the RAM 7, but several sets of these are provided to allow manual specification of multiple single columns of rows and patterns from the console 4. You can also print a page (or line) containing all of the specifications.

In addition, although lines and columns are specified in this embodiment, it is also possible to record coordinates on the print paper, use these coordinates to specify the start and end points of the range to be printed, and print only pages that include lines or rectangles. You can also do it.

[Advantageous Effects of the Invention 1] As explained above, in the present invention, only the page (or line) that includes the specified 2 digits of the line and the pattern is expanded into dots, so only the part of the input data that is desired to be output is It has the effect of being able to print.
