Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an overlay control method for printing within standard format data.

(Prior Art) Conventionally, when printing non-standard information data in a standard format such as stationery or an invoice, both the standard format data and the non-standard information data are overprinted.

FIG. 6 is a diagram showing the state of the standard format before information data is printed, and FIG. 7 is a diagram showing the state after the information data is printed in the standard format.

In FIG. 6, the portion indicated by letters and mouth symbols is a fixed format, and is a portion that has common contents regardless of the destination when sending something.

In addition, the portion indicated by the O symbol in FIG. 7 is non-standard information data, such as the numbers of the document number, the numbers of the year, month, and day, the name of the destination, and the name of the item to be sent.

When printing information data in the blank space of the standard format shown in Figure 6, first print using the standard format data to create the standard format shown in Figure 6, then put the practice format back into the printer and print the information. A document as shown in FIG. 7 is created by printing only the data.

(Intelligence M to be solved by the invention) However, in the conventional overlay control method described above, when it is necessary to create various documents other than stationery and invoices, multiple standard formats are prepared in the printer. It is necessary to keep it. That is, format data for each document is stored in the RAM within the printer, and when a document is designated by an operator, one of the format data is retrieved.

Therefore, a task for document selection becomes necessary, making the operation complicated.

In addition, when printing information data in a fixed blank space, it is difficult to align the printing position of the standard format with the printing position of the information data, and adjustments such as trial printing are required.
Work costs will increase. When information data is printed in a plurality of blank spaces, data input becomes even more complicated.

The present invention solves the problems of the conventional overlay control method described above, and eliminates the need for complicated work even when it is necessary to print data in multiple formats.
Another object of the present invention is to provide an overlay control method that allows information data to be input easily and accurately to a fixed print position of standard format data that is pre-installed in a printer.

(Means for Solving the Problems) To achieve this, the present invention provides an overlay control method for a printer that simultaneously prints standard format data and non-standard information data. write the format data to the memory card and store it.

Then, when the information data is input, the format data in the memory card is read out, and the logical sum of the information data and the format data is taken.

The calculation results are sent to each control section of the space motor and line feed motor, and are printed at the same time.

Also, when inputting format data, store the position and number of characters where the information data will be printed in advance.
Data on the position and number of characters are input into the format data as dummy data, and when the information data is input, the format data is read out, and the logical sum of the information data and the format data is taken.

The calculation results are sent to each control section of the space motor and line feed motor, and are printed at the same time.

(Function) According to the present invention, as described above, first, a memory card is made removably insertable into the printer body, and format data is written and stored in the memory card. therefore,
For multiple documents, each format data can be divided and stored in multiple memory cards.

Then, the operator selects a memory card according to the document to be printed, inserts it into the printer, and inputs non-standard information data.The format data in the memory card is read out, and the information data and format data are combined. A logical sum is taken.

The calculation results are sent to each control section of the space motor and line feed motor, so that the format data and information data are printed at the same time.

Also, when inputting format data, store the position and number of characters where the information data will be printed in advance.
If you input the position and number of characters data as dummy data into the format data, you can input information data into the correct position of the blank space in the standard format.

Then, when the operator inputs information data according to guidance, the format data is read out, and the logical sum of the information data and the format data is calculated.

The calculation results are sent to each control section of the space motor and line feed motor, and are printed at the same time.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

First, an overlay control method for printing information data in a plurality of standard formats will be described.

FIG. 2 is an external view of a printer to which the overlay control method of the present invention is applied.

As shown in the figure, the printer 50 has an insertion port 51 on the front surface, through which a memory card 52 can be inserted into the printer 50 and connected to the control section. .

FIG. 3 is a schematic block diagram of a printer to which the overlay control method of the present invention is applied.

In the figure, 7 is a CPU that controls the entire printer 50.
, 8 is a space motor that moves the print head 9 in the width direction of the print paper, 10 is a space motor driver that drives the space motor 8, 11 is a print head driver that drives the print head 9, and 12 is a space motor that moves the print paper. 13 is a line feed motor driver that drives the line feed motor 12; 14 is a ROM that stores the operating procedure (program) of the CPU 7; and 15 is a RAM that stores print data and the like.

Next, the operation of the overlay control method of the present invention will be explained.

FIG. 1 is a functional block diagram of a printer to which an overlay control method according to an embodiment of the present invention is applied.

First, when standard format data to be printed is input as data for displaying coordinates by, for example, an ESC (ESC+(a, b)) sequence, the coordinate data is input to the format data input section 18 by the decoder 16. . The coordinate data is sent to the X-axis data converter 21
The data is converted into data indicating the print position in the spacing direction, and is converted by the Y-axis data conversion unit 22 into data indicating the print position in the line feed direction.

On the other hand, print data corresponding to the coordinate data of the format data is input to the preprint data input section 19.

The converted coordinate data and print data are then synthesized in the preprint synthesis section 23 and written to the data buffer 53 in the memory card 52 via the write control section 27. The data buffer 53 has a format data area 53a for storing coordinate data and a print data area 53b for storing print data, and the data written in each area is stored and held by a battery 54.

In this way, various types of standard format data to be preprinted are stored in the memory card 52.

Next, when printing is performed with non-standard information data included in a predetermined position of the standard format data, the input information data is sent to the information data input section 20 via the decoder 16. Subsequently, this information data and the format data previously stored in the memory card are logically summed and overwritten.

That is, when the information data is sent to the character/image data conversion circuit 29a, the character/image data conversion circuit WII 29a reads image data from the font memory 17 based on the information data and stores it in the image buffer 32. In this case, the image data is written in one row.

Next, the format data stored in the memory card 52 is read by the read control section 28 and sent to the character/image conversion circuit 29b.

When the character/image conversion circuit 29b receives the format data, it similarly reads the image data from the font memory 17 and sends it to the arithmetic circuit 31.

The arithmetic circuit 31 calculates the logical sum of the information data stored in advance in the image buffer 32 in one row and the format data, and outputs the result of this arithmetic operation to the image buffer 3.
Send to 2. That is, data in which information data is overlaid on format data is stored in the image buffer 32.

This data is input to a space motor control section 33 and a line feed motor control section 34, so that printing is performed at - degrees.

As described above, when printing in multiple standard formats, format data is stored in the memory card 52 for each standard format, so multiple format data are stored in llOH of the printer body. This eliminates the need for format data reading and simplifies the work for reading format data.

Next, the operation of an overlay control method for accurately printing information data at a fixed print position of a fixed formant will be described.

FIG. 4 is a functional block diagram of a printer to which an overlay control method is applied, showing another embodiment of the present invention;
The figure is an explanatory diagram of the guidance function, FIG. 5(A) is a diagram showing a printed document, and FIG. 5(B) is a diagram of the correspondence between guidance information and input data.

First, standard format data to be preprinted is input and stored internally. In this case, the number and position of information data to be printed at a predetermined position in the standard format is known at this stage of setting the standard format, so the data on the number of characters and position is sent at the same time as the standard format data using an ESC sequence, etc. . The data on the number of characters and the position is inputted to the fixed position data input section 41 via the decoder 16, and sent to the storage circuit 42 where it is stored.

On the other hand, standard format data is input to the format data input section 18 via the decoder 16, and is converted by the X-axis data conversion section 21 into data indicating the print position in the spacing direction, and at the same time, the Y-axis data conversion section 22 is converted into data indicating the print position in the line feed direction.

Further, the print data corresponding to the coordinate data of the format data enters the print data input section 19, and the converted coordinate data and print data are synthesized by the synthesis section 43. At this time, the data stored in the storage circuit 42 as fixed position data becomes dummy data, that is, NULL data (HEX
, 00) in the format data.

The synthesized data is written into the data buffer 44 via the write control section 27 and stored and held by the pantry 45.

Next, the guidance circuit 46 prints the guidance information of the fixed position data given in the ECS sequence.

In Figure 5 (A), information data is inserted and printed at the positions marked with notes 1 to -, but when guidance as shown in Figure 5 (B) is printed, the operator can Information data can be input according to the guidance.

Then, when the operator inputs information data, the information data is input to the information data input section 20 via the decoder 16. This data is automatically written to a fixed position by an automatic fixing circuit 47 in accordance with information previously stored in the storage circuit 42, and sent to the character data/image data conversion circuit 29b. The character data/image data conversion circuit 29b reads image data corresponding to the information data from the font memory 17 and stores it in the image buffer 32. The image data is written one line at a time.

Next, as the information data is input, the standard format data in the data buffer 44 is transferred to the read control unit 2.
8 and sent to the character data/image data conversion circuit 29a. The character data/image data conversion circuit 29a reads image data corresponding to the format data from the font memory 17 and sends it to the arithmetic circuit 31.

In the arithmetic circuit 31, the fixed data previously stored in the image buffer 32 in one row order and the format data are logically summed, and the result of this arithmetic operation is overlaid and stored in the image buffer 32.

The data stored in the image buffer 32 is input to a space motor control section 33 and a line feed motor control section 34, so that printing is performed at - degrees.

As mentioned above, since the fixed position data for inputting information data is input in advance by dummy data,
The information data and format data will be automatically aligned.

Note that the present invention is not limited to the above embodiments,
Various modifications are possible based on the spirit of the present invention, and these are not excluded from the scope of the present invention.

For example, it is possible to easily expand the information data by two times, add character decoration functions such as font selection, and adjust the print position according to the number of input characters in order to balance the print position.

(Effects of the Invention) As explained in detail above, first, format data is written and stored on a memory card, the memory card is selected according to the document to be printed and inserted into the printer, and non-standard information data is input. Then, the format data in the memory card is read out, the logical sum of the information data and the format data is taken, and the calculation results are sent to each control section of the space motor and line feed motor, and the format data and the information data are are printed at the same time.

Therefore, by storing a plurality of standard format data on each memory card, inserting the memory card corresponding to the required format data, and inputting the information data to be printed, the information data can be stored in the standard format. can be easily overprinted and printed.

Also, when inputting format data, store the position and number of characters where the information data will be printed in advance.
By inputting the position and number of characters into the format data as dummy data, non-standard information data can be input into the correct position of the blank space in the standard format. When information data is input, the above format data is read out, the above information data and the format data are logically summed, and the calculation results are sent to each control section of the space motor and line feed motor and printed at the same time. It looks like this.

Therefore, there is no need for adjustments such as alignment, and not only can information data be input at accurate printing positions, but also there is no need to consider the order of input when information data is input at multiple locations.
