Abstract
A method and printing system for printing color image data in black and white using a color image forming apparatus is disclosed. The printing method according to the present invention includes determining whether the color image forming apparatus can normally perform color printing according to the state information of the color image forming apparatus; If it is determined that color printing cannot be normally performed, generating color data by converting color image data so that color image data is printed in black and white; And printing the generated print data by using the color image forming apparatus. According to the present invention, when a color image is to be printed, color printing cannot be normally performed, but when black and white printing can be normally performed, the color image can be replaced with black and white. Furthermore, according to the present invention, in this case, the time taken to transmit or process the print data can be shortened.
Description
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.
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.
