Problems solved by technology

[0005] Although some software provides some special functions, such as draft printing, or combined printing to save toner, but for normal printing, the above-mentioned waste of toner due to dark background is often seen
It's actually a big waste and doesn't display well

Embodiment 1

[0028] The sub-area is a point of a binary printer (such as a monochrome inkjet printer or a laser printer), which can only be in two states of on or off, the first output state is a printing state, and the second output state is a non- Print status. That is, the position (pixel) of each dot in the area to be output, either print dots or "no dots". The predetermined condition can be whether the ratio of X to M exceeds a threshold, such as 60%, 70%; the predetermined condition can be whether the ratio of Y to M is less than a threshold, such as 40%, 30%. %; the predetermined condition can also be whether the ratio of X to Y is greater than a threshold, for example, 100%.

[0029] According to the device for processing data to be output in Embodiment 1 of the present invention, firstly, the area to be output is obtained by the image acquisition module 102, and it is determined that the area to be output is composed of M points (for example, M=100). The output status acquisitio...

Embodiment 2

[0031] The sub-regions are units with the same area divided into the region to be output, the first output state is the first grayscale, and the second output state is the second grayscale. The first grayscale value is greater than the second grayscale. For example, if the first grayscale is 50% and the second grayscale is 25%, then the unit with the first grayscale will be printed with a darker color, and the unit with the second grayscale will be printed with a lighter color. The predetermined condition can be whether the ratio of X to M exceeds a threshold, such as 60%, 70%; the predetermined condition can be whether the ratio of Y to M is less than a threshold, such as 40%, 30%. %; the predetermined condition can also be whether the ratio of X to Y is greater than a threshold, for example, 100%.

[0032]According to the data processing device to be output according to Embodiment 2 of the present invention, the area to be output is first obtained by the image acquisition m...

Abstract

The invention provides device and method for processing data to be outputted. The method comprises the following steps of: acquiring a region to be outputted, wherein the region to be outputted comprises M subregions; acquiring X subregions with output states as first output states and Y subregions with output states as second output states from the M subregions; processing any two of the X, the Y and the M to obtain a condition value; and setting the output state of the X subregions with the first output states to be the second output state and setting the output state of the Y subregions with the second output states to be the first output state when the condition value meets a predetermined condition. The invention can effectively save the ink powder, prolong the service time of an inkbox and save the power consumption in long-term use.

Description

technical field [0001] The invention relates to the field of printing, in particular to a processing device and method for data to be output that can be applied to printing, copying, faxing, etc., using toner to display information on paper. Background technique [0002] When printing, I often encounter the following situations: Usually when making documents, I like to add some backgrounds to the documents, so that they will look good on the computer screen. Many backgrounds use dark colors. When printing, it is very Ink consumption, such as a PPT page with a dark background, the proportion of text information is very small, but the toner consumption is hundreds of times that of ordinary black and white documents. [0003] When sending a fax, we often encounter a similar situation. If the original fax has a dark background, the fax speed will be very slow. This is because each background color needs to be processed and transmitted. After sending out, the receiving party , i...
