Abstract

PROBLEM TO BE SOLVED: To provide an image forming device which meets wide variety of printing operations required by a user. SOLUTION: When a data inputting part 1 receives data, a command interpreting part 2 discriminates whether or not the data is a command definition data. When it is not a command definition data, the data is transmitted to a command executing part 4, an operation program corresponding to a command is retrieved from a command storing part 3 and printing processing is performed. When it is a command definition data, it is transmitted to a command defining part 6 and the command is converted into an execution format and stored in the part 3.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming apparatus for receiving data from an external device and performing a printing process.

[0002]

2. Description of the Related Art As shown in FIG. 3, a conventional image forming apparatus comprises a data input unit 11, a command interpretation unit 12, a command storage unit 13, a command execution unit 14, and a printing unit 15. The command interpreting unit 12 divides the data received from the external device into command data and image data, and the command executing unit 14 stores an operation program of the image forming apparatus based on the command data determined by the command interpreting unit 12 in the command storing unit 13. The image data to be printed is printed by the printing unit 15 by receiving and executing the image data.

[0003]

However, the conventional image forming apparatus cannot be operated with a command other than the command stored in the command storage unit 13, and sometimes fails to meet the user's wishes.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has a data input unit for receiving data from an external device, a command interpreting unit for determining command data in the data, and a plurality of data input units. A command storage unit that stores a command and an operation program corresponding to the command, a command execution unit that searches the command storage unit and executes the operation program based on the command data determined by the command interpretation unit; And a printing unit for performing a printing process based on data from the printing unit, wherein the command interpretation unit is configured to be able to determine command definition data including command data to be newly added and operation program information corresponding to the command data. If the command definition data is included in the data from the external device, the command It is obtained by the image forming apparatus to be stored in the command storage unit from the interpretation unit.

With such a configuration, even if a command is not stored in the command storage unit, the command and the corresponding operation program data are received from the external device and stored in the command storage unit before the printing operation. An operation corresponding to the command can be performed.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram showing an image forming apparatus, and includes a data input unit 1, a command interpretation unit 2, a command storage unit 3, a command execution unit 4, a printing unit 5, a command definition unit 6.
And

The data input section 1 is a section for receiving data transmitted from a host computer A which is an external device. The data includes image data that is data such as text or graphics to be printed, command data that is a command for the image forming apparatus, command data that is not stored in the command storage unit 3 and that is to be newly added, and an operation corresponding thereto. Command definition data including program information.

The command interpreting section 2 is a section for determining image data, command data, and command definition data in the data. The command interpreting section 2 transmits the image data and command data to the command executing section 4, and the command defining data is transmitted to the command defining section. Send to 6.

The command storage unit 3 stores a plurality of commands and operation programs corresponding to the commands in advance, and stores a new command from the command definition unit 6 and an operation program corresponding to the command. .

The command execution section 4 is a section that searches the command storage section 3 and executes an operation program based on the command data determined by the command interpretation section 2.

The printing section 5 is a section that performs printing processing based on an operation program of the command execution section 4 and image data.

The command definition section 6 is arranged between the command interpretation section 2 and the command storage section 3 and is provided between the command interpretation section 2 and the command storage section 3.
This is a part that converts the command definition data sent from the CMS into an executable program and sends it to the command storage unit 3. When a complete command and an operation program corresponding to the complete command are transmitted from the host computer A, the command definition section 6 can be omitted.

The operation according to the configuration of the present invention will be described with reference to FIG.

When data is received by the data input unit 1 (step 1), the command interpreting unit 2 determines whether the data is command definition data (step 2). If it is not the command definition data, the data is transferred to the command execution unit 4
To retrieve an operation program corresponding to the command from the command storage unit 3 (step 3), and perform a printing process (step 4). In the case of the command definition data, the command is transmitted to the command definition section 6, the command is converted into an execution format (step 5), and stored in the command storage section 3 (step 6).

[0015]

As described above, according to the image forming apparatus of the present invention, since the command definition data can be stored in the command storage section, the image forming apparatus can respond widely to the printing operation desired by the user. It can be.
