PURPOSE:To increase the type of a control code executing the function of the page printer. CONSTITUTION:A page printer 1 is provided with a reception part 2 receiving information from a host device 20, an edition part 4 with a function judging whether or not the received information from the reception part 2 is a control code and executes a function suited for the control code when it is a control code and converting it into data to be printed when it is not, a control part 3 controlling the printing operation, a control code program part 10 newly registering the control code so as to operate the page printer function on the supplied control code, and a control code storage part 11 storing the newly registered control code.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer device,
In particular, the invention relates to a control code programmable page printer device.

[0002]

2. Description of the Related Art A conventional page printer device operates with one type of control code unique to a page printer device developer.

Alternatively, in order to operate the control codes of many page printer device development companies with one page printer device, an emulation program that operates with the page printer control code of another company is developed and externally attached to the page printer device. It is supplied to users in the form.

[0004]

In the above-described conventional page printer apparatus, since the function corresponding to the control code is determined by each company, the device driver registered in the application program is the type of page printer apparatus. There is a drawback in that as the number increases, more must be added.

When a user who uses an application program adds a device driver, the structure of the device driver has not been clarified by the application program development company, and the device driver cannot be created and added. Has the drawback that the printer output function of the application program cannot be used until the application developer supplies the device driver.

Further, when a page printer development company creates a program for emulating another model, it takes a long development period. Therefore, it is not necessary to develop an emulation program for many models because of a request from a user who uses the application program. It has the drawback of not being able to respond.

SUMMARY OF THE INVENTION According to the present invention, a receiving unit for receiving information from a higher-level device, a judgment is made as to whether the information received by the receiving unit is a control code, and if it is a control code, a control In a page printer device equipped with an editing unit having a function of executing a function suitable for a code and converting into data to be printed if it is not a control code, and a control unit for controlling a printing operation of the page printer device, A control code program unit that receives information sent from the host device through the receiving unit and newly registers a control code to operate the page printer function with a given control code, and a newly registered control code. And a control code storage unit for storing

[0008]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention.

The page printer device 1 determines a receiving section 2 for receiving information from the higher-level device 20, and whether the information received by the receiving section 2 is a control code. It is sent from the editing unit 4 that has the function of executing the matched function and converting it into data to be printed if it is not a control code, the control unit 3 that controls the printing operation of the page printer device, and the host device 20. The information is received through the receiving unit 2, and the control code assigned to the function of the page printer is exchanged with the sent information in order to operate the function of the page printer, for example, the function of discharging the paper, with the sent information. Then, the control code program unit 10 to be registered and the control code storage unit 11 to store the exchanged control code are configured.

FIG. 2 shows the contents of the control code storage unit 11. The default control code table 30 shows the default values of the control codes corresponding to the page printer function, and the converted control code table 31 shows the control code values corresponding to the page printer function after the conversion of the control code. It represents.

Next, the operation of this embodiment will be described with reference to FIGS. 1 and 2.

The printer device 1 realizes the function by the control code of the default control code table 30 of FIG. 2 when the power is turned on, for example.

When two bytes of hexadecimal "1B, 0C" are sent from the host device 20 as a control code, the receiving unit 2
Receives the hexadecimal number "1B, 0C".

Next, the editing unit 4 refers to the control code table registered in the control code storage unit 11 for the information received by the receiving unit 2, and the 2-byte hexadecimal "1B, 0C" is ejected from the paper. The control unit 3 is notified that the function is determined and the paper is ejected.

Next, the control unit 3 discharges the paper according to the paper discharge notification from the editing unit 4.

While the above-described operation is repeated, when the control code switching is notified from the upper level device 20 such that the paper discharging function is operated by 2 bytes of hexadecimal number "1B, 00" of the control code The unit 2 receives 2 bytes of the hexadecimal number "1B, 00" simultaneously with the control code switching notification.

Next, the control code program unit 10 receives the control code switching notification received by the receiving unit 2 from the host device 20 and the 2 bytes of hexadecimal "1B, 00".
Receive from

Next, the control code program section 10 registers 2 bytes of hexadecimal "1B, 00" in the control code storage section 32 of FIG. 2 corresponding to the paper discharge function in the control code storage section 11. .

The result is the control code table 3 after conversion in FIG.
It is 1.

Next, the editing unit 4 converts the information received by the receiving unit 2 into the data to be printed while referring to the control code table registered in the control code storage unit 11.

At this time, since there are 2 bytes of hexadecimal "1B, 00" in the information received by the receiving unit 2, the editing unit 4 uses the paper ejecting function for the hexadecimal "1B, 00". When it is determined that the sheet is present, the control unit 3 is notified that the sheet is ejected.

Next, the control unit 3 discharges the paper in accordance with the paper discharge notification from the editing unit 4.

[0024]

As described above, according to the present invention, when the control code switching is notified from the host device, the new control code given from the host device is registered in the storage unit corresponding to the notified function. By doing so, it is possible to increase the number of control codes that execute the functions of the page printer from one type to many types.

Therefore, for example, if the control code corresponding to the function of the page printer of company A is registered in the page printer device of the present invention, the printer output function added to the application program is exclusive to the page printer of company A. Also, the page printer device of the present invention has an effect of enabling printer output by the application program.

Further, there is an effect that the user can perform printer output without waiting for the device driver suitable for the page printer to be supplied from the application program development company.
