DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an output device such as a printer.
About the command dump function in.

[0002]

2. Description of the Related Art Conventionally, a print recording device such as a printer receives data from a computer as a host device, identifies commands and character data, converts the data into print data, and transfers the print data to a print recording element. Print records.

[0003] In addition, print recording apparatuses have come to have various types of commands in order to respond to various requests.

By the way, in order to output data from the host device side, it is necessary to prepare a program called a driver for each printer, and a driver is required for each application program operating on the host device. Sometimes. When designing and developing this program, it is necessary to know whether each command is correctly sent to the printer.

Therefore, conventionally, a dump function for outputting a list of commands in a hexadecimal display format as shown in FIG. 3 was provided in order to know whether or not the above-mentioned commands were correctly sent. A print recording device is provided.

That is, this dump function checks the contents of this code by inputting specific print data to a printer and outputting a hexadecimal code table as shown in FIG. It is to determine whether it is functioning. In FIG. 3, a 16-digit hexadecimal code string displayed from the left to the center is print data including each command, parameter, and text data, and a character string displayed on the right is 1 character.
The print data of the hexadecimal code is displayed as characters based on the ASCII code. In this character display, all commands included in the print data are displayed as “.”.

[0007]

However, in the above-mentioned prior art, since each data is a hexadecimal code and a display format in which this is converted into a character string as it is, each display data corresponds to what. It is difficult to understand, and it is necessary to actually check each one through a printer manual or the like, which is a very complicated task.

Further, in the conventional display format, the data is divided into 16-digit codes, so that it is not easy to classify each data. For example, it is necessary to rewrite and compare commands transmitted to the printer, and the like. It took a lot of effort and time, and had a considerable effect on the cost of application programs with printer drivers.

An object of the present invention is to provide an output device having a dump function that can easily check a command.

2 and a print buffer 3-3 used for developing the pattern data read from the character generator (CG) ROM 12.

The host device 5 transmits various character codes and control codes to the printer 10 to instruct a printing operation. Data from the host device 5 is received by the data receiving unit 11 and stored in the RAM 3. Is done. The data from the host device 5 includes, as control data, commands specific to the print recording device, such as a designation command for normal characters and high-quality characters, and a print recording start command. The data receiving means 100 shown in FIG. 1 is mainly this part.

The CGROM 12 outputs character patterns corresponding to various character codes, and stores character patterns and information data.

The head controller 13 inputs print data under the control of the CPU 1 and transfers the print data to the head driver 1.
4 is output.

The head driver 14 drives the recording head 15 in accordance with the recording data and prints out on a recording medium such as recording paper.

The timer 16 sends a timing signal to the head controller 13 based on the time setting from the CPU 1 and the CP.
U1 to control the head controller 13 to determine the drive time of the recording head 15 and control the operation timing of the CPU 1.

The information input unit 20 is, for example, a keyboard for inputting a control signal to the printer 10 through the input port 21.
For example, designation of printing of high-quality characters and designation of a command dump print recording function can be performed.

The driving unit 23 outputs a signal C via the output port 22.
The PU 1 has a motor for driving a carriage (not shown) on which the recording head 15 is mounted and a transport unit (not shown) for transporting the recording paper.

FIG. 4 shows a state in which data is output using the command dump function of the present embodiment, and corresponds to the data of FIG. 3 described above.

FIG. 5 is a flowchart for explaining the command dump function of this embodiment.

That is, in this flowchart, when the command dump function is designated by the input unit 20 or a specific command described above, the code received from the host device 5 is analyzed and converted into a character string of the corresponding command. It is a representation of control. Here, only the first row in FIG. 4 will be particularly described.

First, it is determined in S2 whether or not the mode is the command dump mode. If the mode is not the command dump mode, the process shifts to processing for handling normal received data (S3).

If the mode is the command dump mode, the data receiving unit 11 extracts one code of the received data stored in the RAM 3 at S4, and the code is 20 _H (H represents a hexadecimal number) at S5. ) Is identified. If not less than 20 _H treats as received data S6, writing, etc. CGROM12 address the foregoing, the conversion data in the text buffer 3-2.

[0029] When an in S5 less than 20 _H is, S7
In, performs reception data is whether 1B _H decision, unless 1B _H, at S8, performs processing corresponding to each control command. For example, 3 shown in FIG.
The code on the line (0D _H shown in FIG. 3) corresponds to this, and is replaced here with a character string CR, printing is further started, and a paper feeding process is performed.

If it is 1B _H in S7, S
Go to step 9 and replace with the character string ESC and perform the above processing.
Write to text buffer. Then, in S10, further receives receive data from the RAM 3, the data in S11 it is determined whether 34 _H. Then, if not 34 _H performs processing corresponding to each command in S13. For example, the fifth line in FIG. 4 corresponds to this. Further, if the received code is a 34 _H, the process proceeds to S12, and it processes the received code, written in the text buffer 3-2. For example, 4 in the first row in FIG. 4 corresponds to this.

Next, in step S14, since a command (including parameters) is reached, printing is started, paper is fed, and the flow returns to step S4.

By repeating the processing from S4 to S14 in this manner, the command and the text data can be distinguished, and the command dump as shown in FIG. 4 can be performed.

FIG. 6 shows a state in which data is output using the command dump function according to the second embodiment of the present invention. FIG. 7 is a flow chart for explaining the command dump function of the second embodiment. is there.

First, FIG. 6 differs from FIG. 4 in that FIG. 4 simply converts a command sent from the host device 5 into a character string of the command, whereas FIG. It has a function of adding a character string representing a function.

Next, the flowchart of FIG. 7 differs from that of FIG. 5 in that S12-1 and S13-1 are added.
That is, after converting each command into a character string in S12 and S13, S12-1 and S13-1
Then, a character string for explaining the function of each command shown in FIG. 6 is written in the text buffer after the character string of each command.

FIG. 8 shows a third embodiment of the present invention, in which the number of transmissions and receptions of commands sent from the host device 5 is counted, and when printing is finally performed, the received commands are counted. This is an example of printing and recording the total list and the number of receptions.

In the above-described embodiment, printing is started at each command break, and the received data sent from the host device is sequentially printed and recorded. In this example, the number of times corresponding to each command is stored in the RAM 3. And finally, for example, pressing of a predetermined key by the operator or the host device 5
The command dump print recording command is transmitted from the server to start command dump printing, and the number of times each command is received is printed and recorded.

In the above-described embodiment, all the operations are performed on the print recording device. However, the program for the command dump function can be realized in another host device. In other words, the command was converted to a character string in the print recording device, but it was performed on another host device, and the converted character code was displayed on the print recording device and the display attached to the host device. It is possible to

FIG. 9 is a block diagram showing an example of the system in this case. Here, the host device 912 is a device different from the host device 910, and is used in combination with the peripheral keyboard 906 and the display 908. In this embodiment, a command unique to the printing / recording device 911 is identified from the data received from the printing data receiving unit, converted into the above-described character string, and output to the display 908 or the printing / recording device via output ports 907 and 909. The data is sent to 911 for display and printing.
