Abstract

PURPOSE:To enable document image data assigned for multiple colors to be processed as multicolor or monochrome document image data, by performing such an expansion control that multicolor document image data is forcibly expanded in monochrome into one of a plurality of page memories on the basis of monochrome expansion data inputted. CONSTITUTION:While referencing a start flag FG and a force register RT, a CPU 4 serving also as an expansion-controlling means forcibly expands, in monochrome, multicolor image data inputted through an input interface part 3 into either one of a first output page buffer 7a and a second output page buffer 7b. For example, when the force register RT is set to '1', the multicolor image data expanded into the first output page buffer 7a is outputted in black. On the other hand, when the forced register RT is set to '2', the multicolor image data expanded into the first output page buffer 7a is outputted in red. When the force register RT is set to '0', the multicolor image data expanded into the first and second output page buffers 7a, 7b are outputted in multiple colors, namely, in black and red.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printing device that processes an input document image for each color and outputs a multicolor document image.

[Conventional technology]

Conventionally, in this type of device, a document image with specified colors output from a host computer serving as a data source is developed into different page buffers for each specified color, and the colors are specified on the same side of the paper being fed. A desired multicolor image is obtained by forming a document image according to, for example, a known electrophotographic process.

(Problem to be Solved by the Invention) However, among the toners used as developing materials in printers used for multicolor images, there are cases where the toner specified for a color is consumed and there is no toner to replenish. Then,
Even if the data is output, the document image data specified by the color that has run out of toner is not visualized and becomes a blank page.

In addition, even if a request to output document image data with multiple colors specified in a single color occurs due to its output state, the data will be processed with multiple colors specified, resulting in a multicolor image. There was a point.

This invention was made in order to solve the above-mentioned problems, and the printer side forcibly ignores the color specification specified in document image data input with multicolor specification. It is an object of the present invention to provide a printing device that can process document image data specified in multiple colors as multicolor or monochrome document image data by developing it in a page buffer.

Means for Solving Problem C) The printing apparatus according to the present invention includes an instructing means for instructing and inputting monochrome development information for input multicolor document image data into an arbitrary page memory of each page memory; A development control means is provided for forcibly developing multicolor document image data into any one of a plurality of page memories in a single color based on monochrome development information inputted from the means.

If the judgment is No, as shown in FIG. 3(C), the multicolor image data (character data) developed on the second output page buffer 7b is developed in red to form a red image on the same sheet of paper. , if the judgment in step (11) is NO, as shown in FIG.
The character string pattern "ai" developed on the second output page buffer 7b is formed as a red image on the same sheet of paper.

Note that in the above embodiment, a case has been described in which multicolor image data inputted based on a designation from the panel 10 is expanded to either the designated first output page buffer 7a or second output page buffer 7b. It senses that the developer runs out of toner for the first output page buffer 7a or the second output page buffer 7b specified from the panel 10, and automatically develops it to an output page buffer opposite to the output page buffer specified for single color. If controlled, it is possible to shift to a safer side and obtain an image specified as a single color.
