Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

In the related art, when a user prints through a printer and currently needs to print a document, a certain amount of ordinary a4 book paper needs to be placed in a paper box; when a photo needs to be printed, a certain amount of coated paper needs to be placed in the paper box; therefore, if the printed content is different, the required paper may also be different, so that the user needs to change the paper to select the most suitable paper, but when the printed content is changed, the paper needs to be replaced manually, and the operation is troublesome and not automatic enough.

Therefore, the problems to be solved by the present embodiment are: how to realize the automation of printing the selected paper.

Example one

Fig. 2 is a flowchart illustrating a paper selection method according to an exemplary embodiment, where, as shown in fig. 2, the paper selection method is used for a paper selection device applied in an apparatus having a printing function, the method may include the following steps 101 and 102:

in step 101, characteristic information of a document to be printed is acquired.

The characteristic information may be a characteristic of specific contents of the print file, for example, resolution, capacity, and the like. The file to be printed may be received by the printer from a connected computer or terminal, or may be read from a usb disk inserted into the printer, which is not limited in this embodiment.

In step 102, selecting a type to be printed from the types of the alternative paper according to the characteristic information; wherein the characteristic information includes: at least one of content, storage space, resolution, and extension.

The kind of paper may include plain paper, coated paper, specialty paper, photo paper, and the like. The specialty paper is a paper having a special function made of different fibers by a paper machine, and is modified or processed by using a synthetic fiber, a synthetic pulp, a mixed wood pulp, or other raw material alone or in combination with different materials to provide the paper with different functions and applications, such as paper for use in life, building materials, electric products, industrial filters, mechanical industries, agriculture, information, optics, cultural arts, and biochemical advanced technologies, and is generally called specialty paper as long as it is used for a special purpose. For example, copy paper, typewriting paper, glossy paper, newsprint, carbonless paper, and the like are specialty papers. The specialty paper of this embodiment may be of a kind preset in advance.

In the embodiment, there is a corresponding relationship between the feature information and the type, and different feature information corresponds to different types of paper.

In one embodiment, for content, step 102 may comprise:

identifying the content by an image processing technique; when the content is identified as an image, selecting photo paper as a kind to be printed; when the content is identified to comprise the text, determining the proportion of the text in the content; when the text proportion is larger than or equal to the preset proportion, selecting the common paper as the type to be printed; and when the text proportion is smaller than the preset proportion, selecting the coated paper as the type to be printed.

For example, it is first identified whether the content is an image or a combination of images and texts through image recognition, if the content is an image, photo paper is selected as the type to be printed, if the content is a combination of images and texts, the proportion of the text in the content is determined, if the proportion exceeds a preset proportion, the text is printed by using common paper, and if the proportion does not exceed the preset proportion, the text is printed by using other designated paper. For example, when the proportion of the text is more than or equal to a preset proportion (50%), namely the area occupied by the text is more than 50% of the whole content area, automatically selecting plain paper for printing; and when the text proportion is less than 50%, automatically selecting coated paper for printing. Since if no text is recognized, if it is a drawing, it is printed directly on the coated paper of the photograph, in the case of special requirements, it is printed using specialty paper. The 50% may be a preset ratio that is set in advance.

In this embodiment, the text content is usually printed by using plain paper, and the graphics in the content to be printed with a large amount of text are generally used for further printing text characters, so that, on the premise of saving printing paper and being convenient for a user to carry, the content to be printed with a high text proportion only needs to be printed by using plain paper, where the plain a4 paper is one of the plain papers.

In one embodiment, for resolution, step 102 may comprise:

illustratively, the higher the resolution, the better the printing paper is selected. When the resolution ratio is larger than or equal to a first preset rate, selecting paper of a type corresponding to the first resolution ratio, such as special paper, as the type to be printed; when the resolution ratio is greater than or equal to a second preset ratio and smaller than a first preset ratio, selecting paper of a type corresponding to the second resolution ratio, such as coated paper, as the type to be printed; and when the resolution is smaller than the second preset rate, selecting the common paper as the type to be printed.

Illustratively, the higher the resolution of the document content to be printed, the better the paper print is selected. When the resolution is greater than or equal to 500dpi, the corresponding type is specialty paper; when the resolution is less than 500dpi, or less than or equal to 300dpi, the corresponding type is coated paper; when the resolution belongs to the first section and is less than 300dpi, the corresponding type is the common paper. Here, 500 is a first preset rate set in advance, and 300 is a second preset rate set in advance.

In the embodiment, the resolution of the image is generally higher than that of the text, so that the resolution is used as a standard for dividing the image and the text, and the selection process is simplified; and if the resolution of the image is too low, the effect on any paper is almost the same.

In one embodiment, for a storage space, step 102 may comprise:

when the storage space is larger than or equal to the first preset capacity, selecting special paper as a type to be printed; when the storage space is larger than or equal to the second preset capacity and smaller than the first preset capacity, selecting a paper type corresponding to the first capacity, such as coated paper, as a type to be printed; and when the storage space is smaller than the second preset capacity, selecting a paper type corresponding to the second capacity, such as plain paper, as the type to be printed.

Illustratively, the larger the document to be printed, the better the paper print is selected. When the capacity is less than 5M, plain paper printing is automatically selected. When the volume is greater than or equal to 5M and less than 50M, the coated paper is automatically selected for printing; when the volume is greater than or equal to 50M, the special paper printing is automatically selected. 50M is a preset first preset capacity, and 5M is a preset second preset capacity.

In this embodiment, the volume of the image is generally much larger than the volume of the text, so that the volume is used as a standard for dividing the image and the text, and the selection process is simplified.

In one embodiment, for an extension, step 102 may comprise:

when the extension belongs to one of preset image extension sets, selecting a paper type such as photographic paper corresponding to the image set as a type to be printed; when the extension belongs to one of the preset text extension sets, the paper type such as plain paper corresponding to the text set is selected as the kind to be printed.

For example, the extension names of the print documents are different, and the print modes are different. For example, when the file to be printed is a text document, the extension is.doc,. txt, etc., the printing paper is automatically selected to be ordinary A4 paper; the file to be printed is a graphic file, when the extension names are jpg and pnp, the copperplate paper is automatically selected for printing, the file to be printed is a designated file, and when the corresponding extension name is preset, the special paper is automatically selected for printing.

In the embodiment, text content or content mainly comprising text is stored in the text document, and graphic content is stored in the graphic document, so that the text document is more portable and saves cost by printing with plain paper, and the graphic printed by the graphic document with coated paper is clearer and more attractive, so that the variety of the printed paper is fully utilized.

In one embodiment, after step 101, the method further comprises:

Here, when it is judged that the print content is a text document, the printing accuracy is automatically set to normal; when the printing content is an image and the capacity of the printing file and the resolution of the content exceed certain numerical values, the printing precision is automatically adjusted to be high.

In this embodiment, the type of paper can be selected, and then the paper selection device needs to add a paper box with a sorting function, that is, the paper box needs to be partitioned, different paper is placed in each region, and the position of each paper needs to be informed to the device in advance, so as to obtain a proper paper from the corresponding position in the printing process.

Taking a printer as an example, as shown in fig. 3, the paper cassette may be provided in multiple layers, each layer being set with one kind of paper as required, and which layer is set with which kind of paper is set in advance.

When at least two kinds of feature information are acquired simultaneously, at least two kinds of paper can be determined, and a kind with a lower priority is selected. Here, the worse the paper, the higher the priority, i.e., plain paper has a higher priority than coated paper than specialty paper.

For example, if the resolution of the content 100dbi with the text ratio of 40% is acquired, the type corresponding to the text ratio is coated paper, and the resolution is normal a4 paper, then the coated paper has a lower priority than the normal paper, and the normal paper is selected as the printed paper. Here, the priority of the kind of paper is arranged in accordance with the price of the paper, and the higher the priority, the lower the price of the kind of paper.

In this embodiment, the type of paper determined by the single feature information is one-sided, and by integrating at least two types of feature information, the most suitable type of paper can be selected, and the printing cost can be reduced by selecting paper with a high priority.

In step 203, the printing accuracy of printing the file to be printed is determined according to the resolution.

Here, the higher the resolution, the higher the printing accuracy.

In the embodiment, the resolution ratio can be set not only for paper, but also for printing precision, so that the operation of a user is further reduced, and the user experience is optimized.
