Abstract

PURPOSE:To enable the content of data to be understood at a glance and enable easy debugging of a program, by providing a function of printing received data by converting the received data into a instruction format for a printer in a debugging mode according to a control instruction. CONSTITUTION:Received data inputted from a host device 1 to a central controller 2 are translated by a translating part 23 when a first mode is selected by a selecting part 22 through a control instruction part 21 according to an operation on a console panel 3. An output from the translating part 23 is sent to a printer part 26, which operates a printing mechanism 4 to perform printing. When a second mode is selected by the selecting part 22 according to an operation on the console panel 3, a data-dumping part 24 operates a digit-printing part 27 to print hexadecimal digits, for debugging the received data. When the second mode is selected by the selecting part 22 through the control instruction part 21 according to a command from the host device 1 or the console panel 3, an instruction-translating part for translating the instruction format for a printer contained in the received data and an instruction printing part 28 for generating an output for printing the instruction as characters according to an output from the instruction-translating part are operated.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a printing function of received data of a printing device.

The present invention is particularly suitable for use in a printing device for an information processing system using a complicated program.

〔overview〕

In the first mode, the present invention prints received data according to instructions from a host device, and in the second mode, it prints out received data for debugging.
Alternatively, in a printing device that prints multi-digit hexadecimal digits, the data content can be checked at a glance by providing a function that converts the received data into the printer's command format in the 27th code according to a control command and prints it. The program is designed to be easy to understand and debug programs in 14 seconds.

[Conventional technology]

Conventional printing devices have a first mode of printing received data, which is a normal text printing function, and a second mode of printing received data as hexadecimal numbers (hereinafter referred to as digits) for program debugging. data dump).

FIG. 3 shows an example of data dump printing according to the prior art.

Devanog processing was performed based on the print results of this second mode.

[Problem that the invention seeks to solve]

However, in recent years, printing devices have become extremely high-performance and multi-functional, and programs using printing devices have also become extremely complex. Therefore, it is extremely difficult to debug a program based on the print result of a mere hexadecimal digit sequence by the conventional second mode data dump.

An object of the present invention is to solve this drawback and provide a printing device that can be easily debugged.

[Means for solving problems]

The present invention prints received data as hexadecimal digits,
It also has a function of converting the received data into a printing device command format and printing it, and is characterized by having a function of changing to the printing function state by a command from a host device or by operation of an operation panel.

That is, in the present invention, there is provided a means for setting the received data inputted from a host device to a mode for printing according to a print command, and a means for setting the received data to be printed in one or more digits of 16
a In a printing device including means for setting a second mode in which the data is converted into numbers and printed, the received data is converted into a command format of the printing device in the second mode, and this command format is printed along with the numbers. It is characterized in that it includes means for.

[For production]

If the second mode is just a list of hexadecimal digits, -
Debugging is difficult because you cannot understand the meaning by looking at it, but if you convert the command format of the printing device, you can understand it as a character or sentence, which reduces errors and makes debugging easier.

〔Example〕

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

FIG. 1 is a block diagram of an embodiment of the present invention. In FIG. 1, received data input from the host device 1 to the central control device 2 via the interface 5A is sent to the selection section 2 via the control instruction section 21 by operating the operation panel 3.
If the first mode is selected in step 2, translation is performed by the translation unit 23. This output is sent to the interface 5B by the printing unit 26.
The printing mechanism 4 is activated to perform printing. Similarly, when the second mode is selected by the selection section 22 by operating the operation panel 3, hexadecimal digits are similarly printed by the data dump section 24 via the numeric printing section 27 for debugging the received data.

Here, the feature of the present invention is that when the selection section 22 selects the second mode via the control command section 21 in response to a command from the host device 1 or the operation panel 3, the printing device command in the received data is The structure is such that an instruction translation section 25 that translates the format and an instruction printing section 28 that sends out an output for printing the instructions as characters are executed.

In FIG. 2, the numbers on the left side are the results of printing by the conventional data dump function, and the numbers on the right side are the results of printing after converting the received data into an instruction format for the printing device.

Next, the operation will be explained.

The printing device has a functional state jlE that prints the 27th code in response to a command from the host device 1 or operation of the operation panel 3. At this time, when the central control unit 2 receives data from the host device 1, it analyzes the data, consolidates it into a print format consisting of commanded characters and numbers for the rest, and prints it, as shown in Figure 2. conduct.

〔Effect of the invention〕

As explained above, in the present invention, during the second mode for debugging a program, the data sent from the host device is converted into the command format of the printing device and printed. This has the effect of making it easier to discover what has been sent to the program, and debugging the program more efficiently.
