JPH10329367A - Printer capable of printing content of communication data analysis - Google Patents

Abstract

PROBLEM TO BE SOLVED: To execute data analysis without using an external device or a memory for holding communication data, by a method wherein normal data as well as communication data itself which is converted to a printing pattern for data analysis is printed on a printing paper. SOLUTION: Communication data consisting of a control command, printing data and a carriage return code is inputted to a host interface 2. When a mode change switch 5 is not set to a data analysis mode, a control section 3 recognizes that it is in a normal printing mode and develops the printing data to character CG to perform the printing on a printing paper. When the mode change switch is set to a data analysis mode, the control section 3 moves to the data analysis mode. In the data analysis mode, the control section 3 develops all of the data including the command data in the communication data to hexadecimal code which is a printing pattern for data analysis. The control section prints all of the converted data on the printing paper.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer device capable of printing communication data analysis contents, and more particularly to a printer device capable of printing communication data analysis contents connected to an information processing terminal.

[0002]

2. Description of the Related Art Conventionally, a printer of this type is shown in, for example, FIG. A printer device 1 for connecting a data analysis device 7 externally to view and analyze data on a line
0 or the communication data as shown in FIG. 6 is temporarily held in the data holding memory 8 on the printer device 11, and the printer device 11 for displaying and analyzing the data on the display 9 or the upper communication terminal 6 is used. Used.

[0003]

The problem with this conventional printer is that the analysis means is complicated and expensive.
That's what it means. The reason is that the printer of FIG. 5 requires an analyzer for analyzing communication data, and the printer of FIG. 6 requires a memory for holding communication data, an external terminal and a display for displaying data. is there.

An object of the present invention is to provide a printer which can easily analyze communication data by providing communication data analysis means which does not require an external device or a memory for holding communication data. .

[0005]

SUMMARY OF THE INVENTION According to the present invention, there is provided a printer device capable of printing communication data analysis contents. The printer device prints based on data sent from a host device. Analysis means for converting the print pattern into a print pattern for printing on a printer paper.

Further, the printer device capable of printing communication data analysis contents according to the present invention is characterized in that the normal printing or the data analysis printing is executed based on an output of a mode switch for switching between a normal printing mode and a data analysis mode. An analysis means is provided.

Further, the printer device capable of printing communication data analysis contents according to the present invention includes the analysis means for executing the normal printing or the data analysis printing by analyzing a command on the communication data.

[0008]

Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a first embodiment of the present invention. Referring to FIG. 1, a printer 1 according to this embodiment includes an upper interface 2 for receiving data from an upper communication terminal 6, a print control And a mode switch 5 for instructing the control unit 3 to switch between a normal printing mode and a data analysis mode, in addition to a control unit 3 for performing main control such as communication control and communication control, and a printing unit 4 for printing on paper. Is done.

The operation of this embodiment will be described with reference to FIG. 2 showing a flow chart of the operation of this embodiment together with FIG. Normal communication data is composed of a print control command and print data (S1). When communication data is input to the upper interface 2, the control unit 3 identifies the normal print mode or the data analysis mode based on the state of the mode changeover switch 5 and changes the control content (S2). When the mode changeover switch 5 is not set to the data analysis mode, the control unit 3 identifies the normal print mode, develops the print data into characters CG according to the control command, and performs printing on the printer paper (S3, S4). . When the mode changeover switch 5 is set to the data analysis mode, the control unit 3 shifts to the data analysis mode (S
2). In the data analysis mode, the control unit 3 converts all data including the command data in the communication data into a data analysis print pattern (S5). The control section 3 prints all the converted data on the printer paper (S6).

Next, a specific example of the operation of this embodiment will be described in detail with reference to FIG. 1 which explains a specific example of the operation of this embodiment and FIG. The communication data A1 is input to the upper interface 2. The communication data A1 includes a control command, print data, and a line feed code. When the mode changeover switch 5 is not set to the data analysis mode, the control unit 3 recognizes the normal print mode, and prints data which has been subjected to the CG expansion "ABCD" on the printer paper (A2). When the mode switch is set to the data analysis mode, the control unit 3 shifts to the data analysis mode. Then, the communication data is converted to a hexadecimal number which is a print pattern for data analysis by CG.
Expand the communication data on the printer paper to "1C5355
414243440A "is printed (A3).

Next, the operation of the second embodiment will be described in detail with reference to FIG. 4 which is a flowchart for explaining the operation of the second embodiment of the present invention. The printer according to the second embodiment does not include the mode changeover switch 5 shown in FIG. Instead, it has a function to shift to the data analysis mode by a command on the communication data. When communication data is input from the upper communication terminal 6, the control unit 3 identifies whether the communication data is a command for shifting to the data analysis mode (S7, S8). If the communication data is not a command for shifting to the data analysis mode, it is treated as normal print data, converted to characters CG and printed on printer paper (S9, S10). If the communication data is a command for shifting to the data analysis mode, the operation shifts to the data analysis mode without performing the printing operation (S
8, S11). When the communication data is input after shifting to the data analysis mode, all the communication data is converted into a data analysis print pattern and printed on printer paper (S
12, S13, S14).

[0013]

As described above, the first effect of the present invention is that communication data can be analyzed without connecting an external device. As a result, analysis of communication data can be performed more easily than in the past, and maintainability and workability are improved.

A second effect is that a memory for data analysis and a connection circuit for an external display device are not required. As a result, it is possible to provide a means for performing data analysis at a lower cost than a conventional apparatus which performs analysis by connecting an external display device.
