2 is a flowchart illustrating a method of printing color image data in black and white using a color image forming apparatus according to an embodiment of the present invention.

The present invention relates to a color image forming apparatus, and more particularly, to a method and system for printing color image data in black and white using a color image forming apparatus.

The electrophotographic color image forming apparatus has four types of toners of yellow, magenta, cyan, and black to print color images. Together, the color image is printed using appropriately. On the other hand, the color image forming apparatus prints using only black toner to print a black and white image. However, even in a color image forming apparatus, a color image may be printed or a black and white image may be printed according to a user's needs.

However, if the color image forming apparatus cannot print a color image normally, for example, the toners of yellow, magenta and cyan are not enough to print or there is a problem with the toner cartridge containing these toners or the color image forming apparatus. The black toner and the black toner cartridge may be normal even if they are not properly attached to the print cartridge, and the black and white image may be normally printed. Therefore, when it is conventionally determined that a color image is not normally printed, the user sets the print mode of the image forming apparatus to a black and white print mode in advance so that the color image data is replaced with black and white.

However, according to this conventional method, there is an inconvenience that the user must first determine whether the color image printing is normally performed and set the print mode of the color image forming apparatus. On the other hand, according to the conventional method, although eventually printing in black and white, the color image forming apparatus receives the print data of the color image from the host. In general, since the print data of a color image has a larger amount of data than the print data of a black and white image, the time taken to process or transmit the data is larger than the print data of a black and white image. Therefore, according to the conventional method, print data of a color image is spooled in a host and transmitted to a color image forming apparatus by wire or wirelessly, and the bitmap data is data of a format which is actually printable in the color image forming apparatus. Since it is converted, there is a problem that it takes a long time to transfer or process the print data.

An object of the present invention is to provide a method and a printing system that can be replaced by black and white printing in a more convenient state when color printing can not be normally performed, but black and white printing can be normally performed. . Furthermore, in this case, it is to provide a printing method and system that can shorten the time taken to transfer or process print data.

In order to solve the above technical problem, the method for printing color image data in black and white using the color image forming apparatus according to the present invention, (a) the color image forming apparatus is normally colored according to the state information of the color image forming apparatus; Determining whether printing can be performed; (b) if it is determined in step (a) that color printing cannot be normally performed, generating print data by converting the color image data so that the color image data is printed in black and white; And (c) printing the generated print data using the color image forming apparatus.

Preferably, the state information of the color image forming apparatus includes the remaining amount of toner for color printing or whether the toner cartridge for color printing is normally mounted.

Preferably, the step (b) converts the data values corresponding to yellow, magenta, and cyan among the color image data into null values, thereby converting the color image data to be printed in black and white. Convert.

Preferably, in the step (b), if it is determined that the color printing cannot be normally performed in the step (b1), the setting mode of the print mode indicating whether to print the color image data in black and white Determining; And (b2) when it is determined in step (b1) that the print mode is set to print the color image data in black and white, the color image data is converted to print the color image data in black and white to print data. Generating.

In order to solve the other technical problem, a printing system for printing color image data in black and white using the color image forming apparatus according to the present invention monitors the state of the color image forming apparatus and the color image forming apparatus normally performs color printing. A monitoring unit to determine whether it can be performed; A print data generation unit for generating print data by converting the color image data so that the color image data is printed in black and white when it is determined that the color image forming apparatus cannot normally perform color printing; And an output unit for outputting the generated print data to the color image forming apparatus.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description and the accompanying drawings, the substantially identical components are represented by the same reference numerals, and thus redundant description will be omitted. In addition, in the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a block diagram of a printing system for printing color image data in black and white using a color image forming apparatus according to an embodiment of the present invention.

The printing system according to the present embodiment includes a host 10 and a color image forming apparatus 20. The host 10 generates print data using the color image data and outputs the print data to the color image forming apparatus 20. Such a host 10 may be, for example, a personal computer (PC), a workstation, or the like. The color image forming apparatus 20 receives print data from the host 10 and prints the print data on the print paper. The color image forming apparatus 20 may be, for example, a color printer, a color multifunction printer, or the like.

The host 10 includes a monitoring unit 11, a print data generating unit 12, a spooler 13, and an input / output unit 14.

The monitoring unit 10 monitors the state of the color image forming apparatus 20. To this end, the input / output unit 21 of the color image forming apparatus 10 to be described later the state information of the color image forming apparatus 20 according to the result of the state sensing unit 25 to detect the state of the printing unit 24 described later It is transmitted to the input and output unit 14 of the host 10 through, and this state information is transmitted to the monitoring unit (11). As the state information, for example, the toner for color printing, that is, the remaining amount of the toner corresponding to yellow, magenta, and cyan, or color included in the color image forming apparatus 20, or color. Whether the toner cartridge for printing, that is, the toner cartridge for yellow, magenta, and cyan, is properly installed, the remaining amount of toner for black, or whether the toner cartridge for black is properly installed, etc. This can be In addition, the state information may be printing paper presence or jam or not. In addition, the state information monitored by the monitoring unit 11 may be displayed through a user interface (not shown) provided in the host 10, and in this case, the user may display the color image forming apparatus ( The state of 20) can be grasped.

In addition, the monitoring unit 10 determines whether the color image forming apparatus 20 can normally perform color printing according to the state information received from the color image forming apparatus 20. For example, any of the toners corresponding to yellow, magenta, and cyan is less than the amount of the preset size, or any of the toner cartridges corresponding to yellow, magenta, and cyan is If at least one is not normally mounted, it may be determined that the color image forming apparatus 20 cannot normally perform color printing.

In addition, the monitoring unit 10 determines whether the color image forming apparatus 20 can normally perform black and white printing according to the state information received from the color image forming apparatus 20. For example, when the remaining amount of toner corresponding to black is less than the preset size, or when the toner cartridge corresponding to black is not installed normally, the color image forming apparatus 20 may perform black and white printing normally. It can be determined that the state can not be.

The print data generation unit 12 converts image data to be printed by the user, for example, color image data, into print data that is data in a format that can be recognized by the color image forming apparatus 20. In particular, the print data generation unit 12 may be set to operate according to the following two print modes. These two print modes are print modes for setting whether or not to print color image data in black and white if printing in black and white is possible if color printing cannot be performed for some reason.

One print mode is a print mode that causes the color image data to be printed in black and white when the color image forming apparatus 20 cannot normally perform color printing when a command for printing color image data is received. Monochrome alternative print mode. In another print mode, when the color image forming apparatus 20 cannot normally perform color printing, when a command to print color image data is received, a black and white substitute, which is a printing mode that does not perform printing, is performed. Print off mode. The print mode may be implemented to be set by a user through the host device 10 or may be set through a user interface (not shown) of the color image forming apparatus 20. In the latter case, according to the printing mode set in the color image forming apparatus 20, the setting information of the printing mode is transmitted to the print data generating unit 12 through the input / output units 24 and 14, and the print data generating unit 12 ), The print mode should be changed.

If the print data generation unit 12 is in a state where the color image forming apparatus 20 can normally perform color printing as a result of the determination of the monitoring unit 11, as is well known, the color image data is formed into color image data. The device 20 converts to print in color to generate print data.

However, when the monitoring unit 11 determines that the color image forming apparatus 20 cannot normally perform color printing, when the print mode is set to the monochrome alternative print cancel mode, the print data generation unit 12 does not operate, and the user interface (not shown) provided in the host 10 indicates that color printing is impossible so that the user can recognize that the color image forming apparatus 20 cannot perform color printing. Print a warning message.

In addition, when the monitoring unit 11 determines that the color image forming apparatus 20 cannot normally perform color printing and the print mode is set to the black and white alternative printing mode, the monitoring unit 10 As described above, it is determined whether the color image forming apparatus 20 can normally perform black and white printing, and if it is determined that the black and white printing cannot be normally performed, the print data generating unit 12 does not operate. In addition, the user interface (not shown) provided in the host 10 may display a warning message indicating that color and monochrome printing is impossible so that the user can recognize that the color image forming apparatus 20 cannot perform color and monochrome printing. Output However, if it is determined that black and white printing can be normally performed, the print data generating unit 12 converts the color image data to be printed so that the black and white printing can be performed in the color image forming apparatus 20 and prints the data. Create

Color print data is generally generated with data of four colors: yellow, magenta, cyan and black. The print data generation unit 12 nulls data corresponding to yellow, magenta, and cyan when generating the print data so that the color image data can be printed in black and white on the color image growth value 20. To be processed. That is, data values corresponding to yellow, magenta, and cyan are made '0'. By this process, data corresponding to yellow, magenta, and cyan are not developed in the color image forming apparatus 20, and therefore are not printed on the printing paper. However, since the data value corresponding to black is maintained as it is, the result printed in black and white by the color image forming apparatus 20 described later is obtained.

Then, the print data generation unit 12 transfers the print data generated as described above to the spooler 13.

The spooler 13 temporarily stores the generated print data until the input / output unit 14 outputs the color image forming apparatus 20, and the input / output unit 14 stores the print data stored in the spooler 13 as a color image. Output to the forming apparatus 20.

The color image forming apparatus 20 includes an input / output unit 21, a data processing unit 22, a print control unit 23, a printing unit 24, and a state detecting unit 25.

The state detecting unit 25 detects a state of the printing unit 24 to be described later, and outputs state information according to the detected result to the host 10 through the input / output unit 21. Specifically, the state detecting unit 25 may include, for example, a toner for color printing, that is, a toner corresponding to yellow, magenta, and cyan included in the printing unit 20. The remaining amount, or the toner cartridge for color printing, that is, the toner cartridge for yellow, magenta, and cyan is normally loaded, or the remaining amount of toner for black, or the toner cartridge for black is correctly installed. Detect whether or not In addition, the presence or absence of printing paper and whether jams may be detected by the state detection unit 25.

The input / output unit 21 receives print data from the host 10 and transfers the print data to the data processing unit 22 described later. In addition, as described above, the state information of the color image forming apparatus 20, that is, the state information of the printing unit 24 is output to the host 10.

The data processor 21 converts the print data received from the input / output unit 22 into bitmap data, which is data in a format that can be printed by the print unit 24. If the print data generation unit 12 of the host 10 converts the color image data to print in color to generate the print data, the converted bitmap data has four colors of yellow, magenta, cyan, and black. Will contain the corresponding data. However, if the print data generation unit 12 of the host 10 is converted to print in color black and white, that is, if the data corresponding to yellow, magenta, and cyan are processed as null, the print data is generated. The yellow, magenta, and cyan data values of the prepared bitmap data are '0'.

The print control unit 23 receives the bitmap data from the data processing unit, and prints the print unit 24 so that the print unit 24 prints an image on printing paper based on the input bitmap data. In control, the printing unit 24 prints an image on printing paper under the control of the printing control unit 23. If the bitmap data having the data values of yellow, magenta, and cyan is '0' as described above, the printed sheet is printed in black and white. That is, as described above, the print data generation unit 12 processes the data corresponding to yellow, magenta, and cyan as null to generate print data, and the data processing unit 22 causes the generated print data to be bit. By converting the map data, black and white printing is performed through the printing unit 24 as a result.

According to the present invention described above, when the image forming apparatus 20 cannot normally perform color printing when printing a color image, but when black and white printing can normally be performed, the user grasps it in advance or color. There is no need to change the print mode of the image forming apparatus, and the color image can be replaced with black and white for more convenient printing. On the other hand, as described above, the print data generated by converting the color image data to be printed in black and white by the color image forming apparatus 20 is smaller in size than the print data of the general color image. Therefore, the time required for spooling the print data, transferring the color data to the color image forming apparatus 20, and converting the print data into the bitmap data is reduced. The time taken to transfer or process is reduced.

2 is a flowchart illustrating a method of printing color image data in black and white using a color image forming apparatus according to an embodiment of the present invention.

In step 220, the host 10 determines whether the color image forming apparatus 20 can normally perform color printing according to the state information of the color image forming apparatus 20 checked in step 215, and performs color printing normally. If yes, go to step 225; otherwise, go to step 230.

In operation 225, the host 10 generates print data such that the color image data may be printed in color by the color image forming apparatus 20.

In step 230, the host 10 determines whether the print mode is set to the black and white alternative printing mode, and if it is set to the black and white alternative printing mode, proceeds to step 240. If the printer is in the print releasing mode, proceed to step 235.

In operation 240, the host 10 determines whether the color image forming apparatus 20 can normally perform black-and-white printing, and if it is able to normally perform black-and-white printing, the host 10 proceeds to step 250, otherwise proceeds to step 245.

In operation 245, the host 10 displays a warning message indicating that color and monochrome printing is impossible so that the user may recognize that the color image forming apparatus 20 cannot perform both color and monochrome printing.

In operation 250, the host 10 converts color image data to be printed in black and white by the color image forming apparatus 20 to generate print data.

In operation 255, the host 10 outputs the print data generated in operation 225 or 250 to the color image forming apparatus 20.

In operation 260, the color image forming apparatus 20 receives the print data from the host 10, converts the print data into bitmap data, and prints an image on the print paper based on the converted bitmap data. If the print data is generated in step 225, the color image forming apparatus 20 prints the color image. If the print data is generated in step 250, the color image forming apparatus 20 prints the monochrome image.
