Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording apparatus having a dump function for dump-outputting data transmitted from a host.

[0002]

2. Description of the Related Art Conventionally, a recording apparatus of this type is connected to a personal computer or the like and generally used as a recording apparatus called a hexadump or a hexadecimal dump. In many cases, it has a function of printing the received data in hexadecimal.

As described above, when the host device sends various data to the recording device to control the recording device, the function is used to print in hexadecimal notation, and the printed data is printed by an operator or a program. Is analyzed to determine if it was sent correctly.

For example, when a program as shown in FIG. 8 is executed and print information is sent from the host to the printer for printing, if the printer obtains a print result as shown in FIG. It is found that the control command "EscI0" for returning to the normal character in step 5 is not executed. "EscI0" is a control instruction code string for returning to a normal character. Therefore, when the printer sets the print mode of the printer to hexadecimal dump and executes the same program, the dump output as shown in FIG. 10 is obtained. In addition, in FIG.
“B” corresponds to Esc, “0C” in hexadecimal corresponds to a page break (FF), and “0D” in hexadecimal corresponds to a return code (C
Corresponding to R), hexadecimal "0A" is a line feed code (LF)
Corresponding to.

It is judged whether or not the printing of the input data stored in (3) is completed (2), and if YES, the printing is completed.

On the other hand, if the result of the determination in step (2) is NO, it is determined whether or not the current output mode is the dump mode (3). If the result is NO, the received data is printed out according to the normal text output rule. (4), and returns to step (1).

On the other hand, if the result of the determination in step (3) is YES, it is further determined whether the received data or the received data string is a designated code or a designated code string that is designated differently from other data. (5) If NO,
For example, the dump output processing unit 4 expands the character pattern to be dump-outputted based on the font set 1 into the output buffer 6 via the data processing unit 5, and the printer engine 7 performs dump printing as a character pattern (6), step ( Return to 1).

On the other hand, if the determination in step (5) is YES, as shown in FIG. 4, the dump output processing unit 4 dumps the designated code "1B" based on the font set 2 into a data processing unit. 5 is output to the output buffer 6, and the printer engine 7 performs pattern dump printing of the designated code "1B" with the italic emphasized character patterns 11 to 13 shown in FIG. 4 (7), and returns to step (1). .

As a result, in step 6 shown in FIG. 8, the code string "1B4930", which originally corresponds to the italic cancellation command, must be transmitted, but "1B4931", that is, the italic start command is again displayed on the dump list. It is possible to easily search for a transmission data error portion that is transmitting. In the above embodiment, the case in which italic printing is performed as a means for emphasizing a specific code or code string has been described, but the data processing section 5 emphasizes the specific code or code string by double printing, underline printing, or the like.

By adding data by 5, it is possible to further improve the distinguishability.

Further, in the above-described embodiment, the case where the recording device 42 prints the specific data expanded in the output buffer 6 in italics is emphasized. However, in the recording device which cannot use the italic font, as shown in FIG. The character size of the control code parts 31 to 33 is different from that of the other character parts (the control code parts 31 to 33 have a large size different from those of the other character parts in the present embodiment, but the control code parts 31 to 31 are different in the present embodiment). The same effect can be obtained even with a configuration in which 33 is emphasized and printed with a small size different from other character portions).

In the above embodiment, the case where the recording device 42 prints the specific data expanded in the output buffer 6 by italic emphasis printing has been described. However, as shown by the outline characters in FIG. It is also possible to emphasize the specific data strings 45 and 46 expanded to, for example, "1B49". As a result, the dump-output control code string and other data can be clearly identified.
