Abstract

PURPOSE:To prevent an overlapping printing processing of the printing data transferred from a host unit on an already printed portion, by a method wherein an information which was previously printed or set on a medium to be printed is read followed by the judgement of the already printed portion within a printable area on the medium to be printed according to the image information. CONSTITUTION:An information which was previously printed or set on a ledger is read by an image reader 11, and according to the binary image data in white/ black form an already printed portion within a printable area on the ledger is judged by a recognition means (a recognition part 82). The positional relationship is operated based on the judged information and the printing position for the printing data which was calculated in a printing position calculation means (a printing position calculation part 9) on the basis of the printing data from a host unit, and the already printed portion within the printable area on the ledger is judged by a printed position judgement means (a printed position judgement part 10), whereby a printing can be processed accurately without an overlapping printing of the printing data transferred from the host unit on the printed portion.

1 line control section 6, a print processing section 7, a character recognition section 81 that reads and recognizes image data stored in the memory 2, and converts it into predetermined code data;
Similarly, a recognition unit 8 includes a printed part recognition unit 82 that reads image data from the memory 2, processes it for recognition, and determines a printed part within the printable area on the form (not shown), and a host device (not shown). a print position calculation means (print position calculation unit) 9 that calculates the print position on the form (not shown) from the print data transferred from the print data transferred from the print data transferred from the print data transferred from the print position (not shown); and the recognition means (recognition unit) 8. Calculate the print position relationship between the determined already printed part in the printable area on the document (not shown) and the print data calculated by the print position calculation means (print position calculation unit) 9, and calculate the already printed position. It is configured to include an already printed position determining means (an already printed position determining unit) 10 and the like.

In this embodiment, the image reader 11 in the reading unit 1 optically reads characters, symbols, and image information printed or written on the form (not shown), and the binary conversion circuit 12 reads the characters, symbols, and image information printed or written on the form (not shown).
The data is converted into white/black binary data and stored in the memory 2.

The character recognition unit 81 reads image data stored in the memory 2, performs recognition processing, and converts it into predetermined code data. The converted code data is transferred to a host device (not shown) via the main control unit 41 and the line control unit 6, and predetermined processing corresponding to the code data is performed.

When the predetermined processing in the host device (not shown) is completed,
The line control unit 6 receives print data that has been subjected to predetermined processing by a host device (not shown), and the already printed portion recognition unit 82 sequentially recognizes and processes the image data in the memory 2. (not shown) in the upper printable area is recognized and sent to the already printed position determining section 10.

On the other hand, the print position calculation unit 9 calculates the print position on the form (not shown) from the print data received by the line control unit 6, and sends the calculation result to the already printed position determination unit 10.

The already printed position determining unit 10 determines the relative position between the already printed part on the form (not shown) identified and recognized by the already printed part recognizing unit 82 and the print data calculated by the printing position calculating unit 9. The print position determination section 10 performs calculations to determine the already printed position.

Next, the already printed position determining unit 10 causes the printer unit 72 to print new print data without overlapping the already printed part based on the positional relationship determined based on the instructions from the main control unit 4. .

If the already printed position determination unit 10 determines that the print position of the print data overlaps the already printed part on the form (not shown), the main control unit 4 Error processing is performed based on the information from the position determination unit 10.

〔Effect of the invention〕

According to the present invention as described above, there is an effect that printing of print data transferred from a higher-level device can be processed without overlapping the already printed portion.
