Description

Detailed Description of the Invention

[0001]

The present invention relates to a HEX dump function (H
EX is an abbreviation for Hexadecimal number).

[0002]

2. Description of the Related Art Conventionally, some printers have a structure having a HEX dump function. This HEX dump function converts the data transmitted from the host computer or the like into a hexadecimal format, that is, a machine language in the HEX format, and dumps, that is, prints out the data converted into the machine language in the HEX format. Function. The data printed out in this way is called a dump list. Such a HEX dump function prints out the data transmitted from the host computer or the like in the HEX format in the case where a problem such that the scheduled print result cannot be obtained occurs, and is useful for investigating the cause of the problem. It is a function for etc. For example, if a dump list of the contents of the program stored in the host computer is created, it is easy to find a defective part or bug in the program, and it is useful for clarifying the cause of the inconvenience that has occurred.

[0003]

The data transmitted from the host computer or the like to the printer device includes command data for requesting a response from the printer device. For example, a status request command, a printer ID response mode command (ID is an abbreviation for Identification), a print end request command, and the like.
The status request command is a command for requesting the transmission of the status of the printer device.
The response mode command is a command for requesting information as to which printer device the printer is, that is, the identity information of the printer device, and the print end request command is for processing all the received data. It is a command requesting that the printer device give a response to the end of printing to the host computer or the like at the time. Then, the printer device that receives such command data is configured to return a response according to the command to the host computer or the like. For example, assuming that the printer device receives the printer ID response mode command, in this case, the printer device enters the ID response mode, and the host computer or the like side transmits data to the printer device sequentially or randomly, On the device side, processing such as changing the signal of the interface according to the transmitted data is performed. In this case, the host computer or the like checks the interface signal of the printer device to confirm which printer device the printer device is.

However, if the printer device that has received the command data requesting such a response is in the HEX dump mode, the printer device cannot return a response. This is because the HEX dump mode is a mode for printing out the data received by the printer device in the HEX format and creating a dump list. Therefore, when the printer device is in the HEX dump mode, the response from the printer device is not returned to the host computer or the like which has sent the command data requesting the printer device to respond. This causes a problem that the host computer or the like remains in a standby state waiting for a response from the printer device, and its function is stopped.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described with reference to FIGS. First, FIG. 2 schematically shows the overall appearance.
The printer device 1 of the present embodiment is provided with an operation panel 2 and a paper feed unit 3 on its front surface. A printer engine, which is a printing mechanism such as a laser beam printer mechanism inside the housing of the printer device 1 and a printing mechanism driving unit that drives the printing mechanism based on print data transmitted from the host computer 4, is also provided. 5 etc. are built in.

Next, the electrical connection of each part is shown in FIG.
First, a CPU 6 is provided which intensively executes various kinds of processing by performing various kinds of arithmetic processing. The CPU 6 has a program ROM 7 for storing operation programs, a font ROM 8 for storing several kinds of fonts, and rewriting variable data. A RAM 9 that is freely stored and used as a work area and a non-volatile RAM 10 that temporarily stores operation instruction data and the like input on the operation panel 2 are bus-connected, and font data, program data, and the like are supplied from the outside. An IC card 11 used as an option is detachably connected. Further, the CPU 6 has
An engine I / F 12 (I / F is an abbreviation for “inter face”), a panel I / F 13, a host I / F 14 and a disk I / F 15 which are composed of a parallel I / F are bus-connected to the printer device. The controller 16 built into the device 1 is configured.

Next, the printer engine 5 is connected to the engine I / F 12, and the panel I / F 13 is connected.
The operation panel 2 is connected to the host I / F 1
The host computer 4 is connected to 4. A disk driver 17 such as a hard disk, which is an external storage device, is connected to the disk I / F 15.

Here, the operation panel 2 is provided with a HEX dump switch 2a for setting the operation mode of the printer device to the HEX dump mode.
When the EX dump switch 2a is turned on, the CP
A UEX dump mode program is selected from the operation programs in the program ROM 7 by the instruction of U6. Therefore, the HEX dump switch 2a, the CPU 6 and the program ROM 7 are configured to execute the HEX dump mode execution means.

In such a configuration, when data is sent from the host computer 4 to the printer device 1, the data is received by the host I / F 15 and stored in the RAM 9. Then, the data stored in the RAM 9 is converted into a predetermined format, the printer engine 5 is driven by the instruction of the CPU 6, and the printing based on the data is executed.

In the printer apparatus 1 of the present embodiment, when the printing executed in this way is inconvenient, the dump list can be printed out by the HEX dump function provided in the printer apparatus 1. To obtain the dump list, the HEX dump switch 2a on the operation panel 2 is turned on. As a result, the program R
A program in the HEX dump mode is selected from the operation programs in the OM 7, and the operation mode becomes the HEX dump mode. The flow of processing in such a HEX dump mode is shown in FIG.

First, the presence / absence of data reception is detected in step S1, and when the data is received, the data is stored in the RAM 9 in step S2. Then, in step S3, it is determined whether or not the data is command data requesting a response, and if it is determined that the data is not such command data, the data is converted into the HEX format in step S4. . Then, in step S5, the data is printed in the first HEX format. An example of the printing is illustrated in FIG. After printing, the data is cleared in step S6, and the HEX dump processing for that data ends.

On the other hand, when it is determined in step S3 that the data transmitted from the host computer 4 is command data requesting a response, it is determined in step S3-1 that the command data is not an ID response mode command. The command is executed in step S7 on condition that it has been done. That is, a response (data for returning a response) according to the command data is returned from the printer device 1 to the host computer 4. On the other hand, step S3-1
If the determination is the ID response mode command, in step S3-2, the ID response mode command is followed by reception of data (data that returns a response) transmitted from the host computer 4 to the printer device 1 sequentially or randomly. Waiting, and in step S3-3, a status corresponding to the data for returning the response (data for returning the response) is transmitted to the host computer 4.
When the processing in step S7 or step S3-3 ends, the process proceeds to step S8, and in step S8, it is determined whether to print the command data confirmed in step S3. Whether to print the command data is set in the emulation program held by the printer device 1. When it is determined in step S8 that the command data is to be printed, step S9
In step S10, the command data is converted into the HEX format, and in step S10, the command data is printed in the second HEX format. An example of the printing is illustrated in FIG. On the other hand, if it is determined in step S8 that the command data is not printed, the process proceeds to step S6, and data clear processing is performed.

When the command data is printed in the second HEX format in step 10, it is determined in step S11 that follows whether or not the response data is printed. The data to be returned here is the data returned from the printer device 1 to the host computer 4 in response to the command received in step 7, or the host computer 4 to the printer device 1 confirmed in step S3-2. Data sent to the host computer 4 from the printer apparatus 1 in step S3-3. Whether to print the data that returns such a response is set in the emulation program. Here, step S11
If it is determined to print the data that returns the response in,
The data returning the response in step S12 is converted to HEX format, and the data returning the response in step S13 is the third H
Printed in EX format. An example of the printing is illustrated in FIG.
On the other hand, if it is determined in step S11 that the response data is not printed, the process proceeds to step S6 and data clear processing is performed.

As described above, in this embodiment, the data received in the HEX dump mode is the data received in step S4, S9 or S.
At 12, it is converted to HEX format. Therefore, the data conversion means is executed by these steps S4, S9 or S12. Then, the data converted into the HEX format is printed in the HEX format in step S5, S10 or S13. That is, the printer engine 5 is driven, each data is printed, and the dump list is printed out. Therefore, these steps S5, S10 or S
By 13, the HEX dump means is executed.

In step S3, it is determined whether the data transmitted from the host computer 4 is a command requesting a response, and the data identification means in the HEX dump mode is executed. Then, if the received data is command data requesting a response, the command is executed in step S7 if the data is not an ID response mode command, and if the data is an ID response mode command, the host in step S3-3. The status is transmitted to the computer 4. Therefore,
By this step S7 or step S3-3, the HEX
The response means is executed in the dump mode. The command is thus executed in step S7, and step S3-
Since the status transmission is performed in 3, the inconvenience that the host computer 4 that has transmitted the command requesting the response to the printer device 1 in the HEX dump mode is stopped is prevented, and the printer device 1 and the host computer 4 are prevented. Data can be smoothly transmitted and received between and.

Next, when it is determined that the command data is not printed in step S8, the data is not converted into the HEX format and the printing is not executed, so that the HEX dump function is stopped for the command data. The command data is cleared as it is in step S6. Therefore, the HEX dump stop means is executed by this step 8. As a result of such processing being performed, when a certain data is HEX dumped, the inconvenience that command data is mixed in the HEX dump print of that data is avoided, and an easy-to-understand dump list is provided.

Further, as is clearer from the dump list of FIG. 4 exemplifying a normal HEX dump print example and the dump list of FIG. 5 exemplifying a HEX dump print example of command data, the dump list relating to command data is underwritten. Line 18 is added. This allows the HEX dump printing of command data to be based on other data.
It is distinguished from the dump printing to clarify the distinction between them, and an easy-to-understand dump list is provided. Therefore, step S for realizing the HEX dump of such command data
10, the command print distinguishing unit is executed.

Then, in step S12, the data for returning the response is converted into the HEX format, and the response data converting means is thereby executed. In step S13,
The data that returns the response is printed, and the response data H
The EX dump means is executed. In this way, a dump list is also obtained for the response data sent from the host computer 4 to the printer device 1 in the response mode, which is useful for investigating the cause when the response from the printer device 1 is inconvenient. . Moreover, the dump list of FIG. 4 exemplifying a normal HEX dump print example and the dump list of FIG. 5 exemplifying a HEX dump print example of command data and the dump list of FIG. 6 exemplifying a HEX dump print example of data returning a response As is clear from the comparison between and, the dump list regarding the data for which the response is returned is shaded. As a result, the HEX dump print of the data returning the response is distinguished from the HEX dump print based on the other data, the distinction is made clear, and an easy-to-understand dump list is provided. Therefore, the response data print distinguishing unit is executed in step S13 for realizing the HEX dump of the data that returns such a response.
