Abstract

The present invention prints the print data in accordance with a predetermined control signal input to the engine unit; The command interpreting means detects the type of file by analyzing file information contained in the file transmitted from the outside; The image converting means interprets the image size and resolution of the image file and the color information for each dot based on the file information to convert the image file into printable data according to the file information; The control means determines whether the file is an image file by file information of the file interpreted by the command interpreting means, and if the file is the image file, controls the image converting means so that the image file is converted into print data and output from the engine unit. There is a characteristic. Therefore, when the computer transmits an image file, the printer itself interprets the header information contained in the image file, converts the image file into print data, and then prints the image file, thereby not executing the application of the computer. It is possible to provide an convenience to the user by enabling the printing of the image file even in the state.

Description

Apparatus for printing image file of printer}

The present invention relates to an image file printing apparatus of a printer, and more particularly, to an image file printing apparatus of a printer which converts an image file transmitted from the outside into print data in the printer and prints the same.

Generally, a printer is an office device connected to a computer and outputs printed matter on printing paper. The printer receives a document or image file created or edited on the computer and converts it into a printing language suitable for the printing conditions set up. It is a device that outputs to paper using colored dye such as toner.

To print an image file (BMP, TIFF, JPG, etc.) using such a printer, the printer does not have a command interpreting function for interpreting the image file. To print an image file, run an application program on a computer and print the image file. The image file to be printed or printed is connected with an application program and then printed as shown in FIG. 1.

However, according to such a conventional printer, the following problem occurs.

When the user prints the image file, I have to run the application of the computer every time, but the image file is printed, so I felt inconvenient when printing the image file.

Accordingly, an object of the present invention is to solve such a problem, and an object of the present invention is to transmit an image file from a computer, and the printer itself interprets a header included in the image file to convert the image file into print data and then convert the image file. By printing, an image file can be printed even without executing an application program of a computer, thereby providing convenience to a user.

A feature of the present invention for achieving this object is that the engine unit prints print data in accordance with a predetermined control signal input; The command interpreting means detects the type of file by analyzing file information contained in the file transmitted from the outside; The image converting means interprets the image size and resolution of the image file and the color information for each dot based on the file information to convert the image file into printable data according to the file information; The control means determines whether the file is an image file by file information of the file interpreted by the command interpreting means, and if the file is the image file, controls the image converting means so that the image file is converted into print data and output from the engine unit. Is in point.

Here, the file information is a header in which information about the file is recorded.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a block diagram schematically showing a printer to which the present invention is applied.

As shown in FIG. 2, the central processing unit 100 receives a printer command or a file from a computer PC and transmits the same through the interface unit 500 to interpret the final print data. After converting to a temporary storage in the memory 200, and outputs the image data stored in the memory 200 to the engine unit 300 to print on the print paper. In particular, when the image file is transmitted from the computer, the command interpreting apparatus 600 and the image converting apparatus 700 are controlled so that the transmitted image file is converted into print data and output from the engine unit 300.

The memory 200 temporarily stores image data under the control of the CPU 100, and stores a program required for the system.

The engine unit 300 is configured to print image data temporarily stored in the memory 200 under the control of the central processing unit 100.

A display device (not shown) provided in an operation panel (OPE) 400 displays the state of the printer under the control of the central processing unit 100, and various function keys provided in the operation panel 400 ( When a function key) is operated, various states such as initializing the printer are adjusted.

The interface unit 500 is configured to receive various data transmitted from the computer PC.

The command handler 600 analyzes the header included in the externally transmitted file and determines whether the transmitted file is an image file.

If the file transmitted from the outside is an image file, the image builder 700 interprets the size and resolution of the image and color information for each dot by the header for the image and converts the image data into printable data. Let's do it.

3 is an operation flowchart for explaining the operation of the image file printing apparatus of the printer according to the present invention.

Sending an image file directly to the printer (for example, in DOS state) without printing the image file without the user running or linking an application on the computer (e.g. Paint). To print an image file, enter COPY 1.BMP PRN and send 1.BMP image file) (S10). The printer command interpreter 600 analyzes the header of the image file transmitted from the computer and transmits the file. It is determined whether or not the image file is an image file (S20).

Thus, when the externally transmitted file is determined to be an image file (S30), the image conversion apparatus 700 may print after analyzing the size and resolution of the image and color information for each dot by the header for the corresponding image. Convert to print data (S40).

Then, the central processing unit 100 detects that the image file is converted to the print data is completed in the image conversion apparatus 700 (S50), when the conversion is completed in the image conversion apparatus 700, the engine unit 300 The print data converted by the control is output (S60).

In operation 30 (S30), if the print data is not the image file, the print data transmitted through the general printing process is printed (S31).

Therefore, when the image file is sent to the printer, the image file is converted into print data for printing, and then directly printed, so that the image file can be printed directly from the printer without executing or connecting an application program of the computer.

As described above, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the claims below and equivalents thereof.

As described above, according to the present invention, the following advantages occur.

When an image file is sent from the computer, the printer itself interprets the header contained within the image file, converts the image file into print data, and then prints the image file so that the image file can be printed without running an application on the computer. To provide convenience to the user.
