Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a dump output device that interprets input character information and control information, and identifies and outputs the authenticity of the received information.

(Prior Art) Conventionally, devices that process various data, such as laser beam printers, have been developed to be equipped with a received data dump (DIMP) function in order to determine the authenticity of received data. It is often set as an output mode independent of normal text output.

That is, in the normal text output mode, the received character code is replaced with a character pattern and output, the control information is converted into the corresponding control processing, and the result is printed out in the format shown in FIG. 4(a), for example. ing.

FIG. 4(a) is a schematic diagram illustrating an example of a printed character string.

In order to print each character string shown in this figure, character code information corresponding to the print character string and print control information related to printing are received, and the character string that is actually printed corresponds to the character code. Since it is only a character string, for example, even if a printing error is discovered, it is not possible to analyze where in the received data the error has occurred.

Therefore, when the dump output mode is set, as shown in Figure 4 (
As shown in b), the control information 1-character code information received for the print character string shown in FIG. ing.

Furthermore, as shown in FIG. 4(C), there was a device that simultaneously outputs a hexadecimal code display and a corresponding character display, but this makes the data output complicated.

[Problem that the invention seeks to solve]

However, for example, if the device that processes the received data is an image output device such as a laser beam printer, the transmission data sent from the host side simply includes character code data (character information) for outputting as characters. In addition, various information is included, such as control command data (control information) for controlling printing and various parts of the image output device, and image data (image information) used when outputting an image.

However, the conventional dump output is as shown in Fig. 4(b).

As shown in (C), all the received data are
It is often output as hexadecimal code or characters. When outputting all received data as characters, the received data must be confirmed and corrected while identifying control commands and character data from the character output, resulting in a dump output whose expression format is quite different from that of control commands. It ends up.

On the other hand, when all received data is output as code data, it is necessary to determine the type of data from the output code data, which is a very time-consuming and complicated task, resulting in errors in determination, etc. There was a serious problem in that careless mistakes occurred frequently and data correction efficiency was significantly reduced.

This invention was made to solve the above problems, and by changing the output expression format of dump output data output in dump output mode according to the type of received data, it is possible to convert dump output data into individual received data. The object of the present invention is to obtain a dump output device that can output dump data in a matching expression format.

[Means for solving problems]

A dump output device according to the present invention includes an analysis means for individually analyzing the type of dump output data output from the dump output means, and an output of each received data based on the type of received data analyzed by the analysis means. Dump data output means for outputting the dump data in a changed format is provided.

[Effect]

In this invention, the analysis means individually analyzes the type of dump output data output from the dump output means, and the dump data output means outputs each received data based on the type of received data analyzed by the analysis means. Change the format and output.

〔Example〕

FIG. 1 is a configuration block diagram of a page printer showing an example of a dump output device according to an embodiment of the present invention, and 1 is a host computer that generates character data (character code) and control commands (control code). and input it to the character generation control unit 2. 3 is a manual buffer for temporarily storing character data (character code) and control commands (control code) input from the host computer 1; 4 is a CPU composed of, for example, a general-purpose microprocessor, which, in normal printing mode, analyzes the human data stored in the human power buffer 3, performs control corresponding to received commands, and performs control corresponding to the received command, and prints characters corresponding to character codes. A pattern is selected and developed in the output page buffer 7.

On the other hand, in the dump output mode, all received data sent and received is outputted to the dump generator 6 as dump data 4b. At this time, the CPU 4, which also serves as the analysis means of the present invention, determines whether the received data is data that is actually output as an r character.
The dump format control unit determines whether the data is "command data for performing some kind of control" or "data whose numerical value itself has meaning, such as image data," and sends a dump format command 48 corresponding to the determined data type. Send to 5.

The dump format control unit 5 receives a dump format command 48 indicating the type of data, and sends a dump expression format command 5a to the dump generator 6. The dump generator 6 receives and receives an expression format command 5a and dump data 4b from the dump format control unit 5.
is converted into character pattern 6a and output page buffer 7
Transfer to. In the output page buffer 7, this character pattern 6a is sequentially stored in accordance with the output position control information 4C. When the storage of the character pattern 6a is completed, the dot image 7a is converted into a video signal 8a via the printer interface unit 8 and sent to the page printer 9 after the I10 timing of the page printer 9 is obtained.

FIG. 2 is a diagram explaining an example of the dump output output from the page printer 9 shown in FIG. 1, and 21 is character dump output data, which corresponds to the character code when the received data is a character code. This shows the state in which the character font is output.

22 is command dump output data, page printer 9
This figure corresponds to command data for controlling the system, and shows a state in which the output matches the expression format described in the instruction manual.

Reference numeral 23 indicates image dump output data (data whose numerical values themselves have meaning), which is output in hexadecimal code.

Next, the dump output control operation according to the present invention will be explained with reference to FIG.

FIG. 3 is a flowchart illustrating the dump output control operation in the present invention. Note that (1) to (9) indicate each step.

When the output starts, the host computer 1 starts transmitting the data code.

First, data stored in the input buffer 3 is read one unit at a time (1). Next, it is determined whether printing of all the human-powered data stored in the human-powered buffer 3 has been completed.
), if YES, printing ends.

On the other hand, if the judgment in step (2) is NO, it is necessary to judge whether the current output mode is dump mode or not. 3)
, if No, the received data is printed out according to the normal text output rules 4), and the process returns to step (1).

On the other hand, if the determination in step (3) is YES, it is further determined whether the received data is output as a character corresponding to that code, that is, character information5), and if YES, the character data is 6), step (1) to print out the character pattern dump (character dump output data 21 shown in Figure 2) according to the dump expression format for
).

On the other hand, in step (5), if NO, it is determined whether the command data controls the page printer 9 (7), and if YES, the command dump output data (7) is determined according to the dump representation format that matches the format of the command. Command dump output data 22 shown in Figure 2
) is output (8) and returns to step (1).

On the other hand, if the determination in step (7) is NO, that is, if it is image data, the image dump output data 23 shown in FIG. 2 is output as image data dump data9), and step (1) Return to

This allows the user to immediately determine the data expression format of the dump, ascertain the authenticity of the received data, and quickly move on to data correction.

Although the above embodiment has been explained using a page printer as an example, the present invention is not limited to this, and the present invention can be easily applied to a medium that sends and receives character information and control information and outputs the analysis, such as a display device. This allows for easy confirmation and correction of received data.

In addition, in the above embodiment, "character information", "control information", "
Although we have explained the case where dump output is performed for three types of data such as "image information", other combinations and data from other complex control systems can be output using similar processing so that the authenticity of the information can be identified. It becomes possible to do so.

[Effect of the Invention] As explained above, the present invention includes an analysis means for individually analyzing the type of dump output data output from the dump output means, and an analysis means for individually analyzing the type of dump output data output from the dump output means, and an analysis means for individually analyzing the type of dump output data output from the dump output means, and Since the dump data output means changes the output form of the received data and outputs it, dump output can be obtained in an expression format that matches each received data, making it easier to identify the type of data. This has an excellent effect in that anyone can efficiently perform dump data discrimination and correction processing in a short period of time.
