Description

Image printing system and method of selecting printing language used to translate origianl document}

The present invention relates to an image printing system and a method for selecting a coding language for a printer of an original file to be printed. Specifically, the present invention relates to a method for selecting a printer language of an original file, selecting a printer language appropriately, and converting the image into print data. An image printing system and a method for selecting a coding language for a printer of an original file to be printed.

An image printing system has a computer and a printer connected via mutual cables or networks.

In such an image printing system, when a print target document file data stored in a computer is converted and coded into a printer language and transmitted to a printer, the printer translates the image and prints the corresponding image on the loaded paper.

When the printer in charge of printing is an electrophotographic method, an image is formed by spraying a toner or a liquid ink in a solid developing material onto a photosensitive medium on which an electrostatic latent image is formed by exposure, and then making contact with the photosensitive medium. By feeding and passing the paper loaded in the paper cassette between the rotating rollers, a desired image can be printed.

In such an image printing system, when the print instruction is issued, the printing target document file data stored in the computer is conventionally set to be coded into the print data by a language coder for the printer designated by the user and designated by default. there was. Since the coding of the original file data in the printer language is performed by one basic coder set as the default value, the user can use the image characteristics of the original file, for example, whether it is for words, graphics, or presentations. When you want to install and use various coders provided to be appropriately expressed in an appropriate print language, it is inconvenient to install or designate a basic coder every time a print instruction is made. In addition, users who do not have the ability to install and install various coders that can be optimally applied in print quality and print speed according to the type of original do not select appropriate coders according to the image characteristics of these various original files. Since the conversion to the language for the printer is performed by only one coder which is basically set, the coder cannot be selected appropriately according to the characteristics of the original file, and the print quality and print speed are not automatically optimized according to the type of the original file. There is a disadvantage.

The present invention has been devised to improve the above problems, and it is possible to automatically select the most suitable language for the printer according to the document characteristics of the document to be printed, an image printing system capable of obtaining high-speed, high-quality print quality, and its printing. An object of the present invention is to provide a method for selecting a coding language for a printer of a target document file.

Hereinafter, an image printing system and a method of selecting a coding language for a printer of a print target document file according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing an image printing system according to the present invention.

Referring to the drawings, in the image printing system, the user computer 10 and the printer 20 are interconnected by a cable or a communication interface 30 via a network.

The user computer 10 has a central processing unit (CPU) 11, a ROM 12, a RAM 13, a storage device 15 connected by the bus 14, and an input. The device 16 has a monitor 17 which is an output device. The input device 16 includes a keyboard and a mouse.

The memory device 15 is provided with a plurality of coders 15b and coding selectors 15a. Postscript, printer controll language (PCL), and graphic data intergace (GDI) are coders 15b provided by ADOBE, HP, and MS (microsoft), respectively. The parts that contribute to print speed have different language systems for printers. In addition, various coders 15b having improved printer language systems have been continuously released due to technology development for improving printing technology. The coding selector 15a analyzes the document characteristics of the original file to be printed, selects one of the coders 15b having different language systems as the print data conversion coder 15b, and selects the selected coder ( The print data conversion process and its sending by 15b) are controlled. The characteristics of the original file of the coding selector 15a and the selection process of the coding machine 15b are determined by extension and / or average document size size analysis per page. The method of selecting a coding language for a printer of a document to be printed will be described in detail together.

On the other hand, the printer 20 connected to the computer 10 by the communication interface 30 is provided with a printer controller 21, a printer engine 22, an input panel 23, and an auxiliary storage device 24. .

The printer controller 21 controls the print job of the printer engine 22 by translation of the print data received from the computer 10 through the communication interface 30 and the translated data.

In the case of the wet electrophotographic method, the printer engine 22 ejects an optical latent unit for forming an electrostatic latent image on a photosensitive medium, and develops an image by spraying an electrostatic latent image formed on the photosensitive medium by spraying toner or liquid ink in a solid state. A developing device and a transfer device for transferring an image formed on the photosensitive medium to a sheet of paper fed thereto.

The input panel 23 is provided outside the main body so that a plurality of input keys are provided to select various printing functions provided by the printer 20, and a key input signal is output to the printer controller 21.

The auxiliary memory 24 is provided with translators corresponding to the coders 15b.

This image printing system will be described with reference to Figs. 2 and 3, which show a flow chart of a method for selecting a coding language for a printer of a print target document file according to the present invention.

First, a process in which a user designates a document file of a created document or a document stored in the storage device 15 as a print target document, sets printing conditions therefor, and inputs a print confirmation key input signal through the input device 16. After the print instruction is finished (step 100), the extension name of the printed original file is read (step 200).

Then, it is judged whether the printer language coder 15b can be selected for the read extension name (step 300). At this time, in the selection process of the coder 15b based on the extension name, the extension group table belonging to each coder 15b is preset and prepared, and it is determined whether it belongs to the set extension table group. In general, each application program for creating a document is to use an extension name recommended for each type of document to be created. Examples of extensions belonging to the PostScript coder 15b family include .ps, .eps, and .pdf. In addition, extensions such as .tiff, .pcx, and .pct belonging to the graphic coder 15b series include .ppt as the extension of the presentation coder 15b series, and word coder. The extension names of the (15b) series include .txt, .doc, .rtf, .wri, .gul, and .hwp. Therefore, the extension names belonging to the group are written in the table table for each coder 15b, and it is first determined whether the extension name of the print target document file belongs to the extension group in the table table.

An example of this process is shown in FIG. 3. First, it is determined step by step whether it belongs to PostScript series, graphic series, presentation series, or word processor series from the extension of the original document file, and if it belongs to any one series, the coder set for each series ( 15b) is selected as the language coding target for the printer (400), and if it does not match any one of the extension groups listed in each series, the default coder 15b is selected (500). Here, in selecting the coder 15b when it does not match any of the extension groups listed in each series, one coder 15b may be set as a default value without any internal calculation process. Preferably, the selection process of the single coder 15b is performed by comparing the average document capacity size per page for the entire document of the original file with the set value (510).

Considering that a graphic document has a larger amount of information than a text document, for example, the comparison setting value is 5K bytes. If the average capacity per page of the document is larger than 5K bytes, the graphic coder 15b is selected. If it is smaller than that (520), a process for selecting a word processor (i.e., a character processing coder 15b) is performed (530).

After the selection process of any one of the coders 15b is completed, the print data is obtained through the coding operation of the print target document file by the selected designated coder 15b (600), and the print data is transmitted to the printer 20. do.

The naming of the coders by the graphic coder 15b, the character coder 15b, the presentation coder 15b, and the like through the explanation process, indicates that the document original characteristics are the same as the extension or page average capacity. After the analysis by the same method, the selection specification of the coder 15b that fits the classified original characteristics cannot be determined by the user on the basis of the judgment of the print quality and the print processing speed for each of the various selectable coders. Since it has randomness, the name that can be applied as a specific example is avoided in consideration of the fact that the selection criteria can be different for each user.

As described so far, according to the image printing system and the method of selecting a coding language for a printer of a document file to be printed according to the present invention, the printer language coders installed according to whether the document characteristics of the document file to be printed are for text or graphics, etc. By selecting an appropriate one of them automatically so that the coding process can be performed, high-speed, high-quality print quality can be obtained.
