Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions of the present invention with reference to the specific embodiments of the present specification and the accompanying drawings. It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments in the specification without making any creative effort belong to the protection scope of the specification.
The technical solutions provided by the embodiments are described in detail below with reference to the accompanying drawings.
Fig. 1 is a control process of a printer according to an embodiment of the present invention, which may specifically include one or more of the following steps:
and S100, determining a target document from the queue of the documents to be printed.
The printer control process of the present invention may be executed by a control system of the printer. In this embodiment, the printer may be connected to several terminals, as shown in fig. 2. Documents to be printed are received from a number of terminals. In general, a printer can print only files to be printed one by one, and documents to be printed, for which printing has not yet been started, are arranged in a queue to wait for printing.
In a preferred embodiment, this step is triggered to be executed when the printing of the document currently printed by the printer is finished.
Further, in a preferred embodiment, the number of the documents to be printed may be determined first, and if the number exceeds a number threshold (a preset value is positively correlated with the printing speed of the printer), the first document to be printed in the queue may be used as the target document determined in this step. If there are multiple documents to be printed in the queue, it indicates that there are documents that have been waiting long, and should not have documents waiting too long to continue waiting.
Further, in a preferred embodiment, if the number does not exceed the number threshold, it is determined that a document containing a graphic in the documents to be printed is taken as a first type document, and a document containing no graphic is taken as a second type document. The target document is preferentially determined from the first type of documents.
S102, reading the document content in the target document; wherein the document content comprises characters and/or graphics.
In the present embodiment, the positions other than the blank position in the page of the document are positions corresponding to the document contents. The area ratio may be a ratio of the area of the non-blank locations to the area of the page.
And S104, determining the area proportion of the document content in the page of the target document.
In a preferred embodiment, a preset second imaging model is used to generate an image representing the printed target document. And determining the area proportion occupied by the non-blank area in the image in the page of the target document. Specifically, the second imaging model has a function of calculating a ratio of the number of pixels corresponding to the document content in the image to the number of all pixels in the page of the target document.
Specifically, the process of determining the area ratio is as follows: and determining the proportion of the area occupied by the non-blank area in the image in the page of the target document as the intermediate proportion. It is determined whether the target document contains graphics. If so, taking the product of the intermediate proportion and the third weight as the area proportion; wherein the third weight is inversely related to an amount of remaining toner in the printer cartridge, and the third weight is greater than 1. If not, the intermediate proportion is taken as the area proportion.
The process of determining whether there is a graphic in the page may be determining a distribution of points in the page corresponding to the document content according to the second imaging model. And clustering the pixel points corresponding to the document content to obtain a plurality of clusters. For each cluster, the area of the cluster is determined. The target number is determined based on the area of the cluster. The target number is positively correlated with the area of the cluster. And if the number of the designated pixel points in the cluster is greater than the target number, determining that the cluster corresponds to the graph. The appointed pixel is a pixel which is adjacent to the periphery of the adjacent pixel and corresponds to the document content.
It can be seen that, in this embodiment, if a certain page has a character with a large font, so that the stroke of the font is thick, the character is also recognized as a graphic instead of a character. It can be seen that, in the embodiment, from the actual printing effect of the file content, what the to-be-printed content is specifically distinguished, rather than distinguishing the to-be-printed content based on the inherent attribute of the file content.
S106, judging whether the area ratio is larger than a first threshold value, if so, executing a step S108; if not, go to step S122.
The first threshold in this embodiment may be a preset value. Whether the area ratio is greater than the first threshold indicates that printing the page will consume more toner.
S108: determining the total consumption amount of toner consumed under the condition that all documents to be printed are printed; and, a consumption first component of toner consumed in the case of printing the target document is determined.
In a preferred embodiment, the process of determining the total consumption amount is to generate images representing all printed documents as reference images by using a preset first imaging model;
from the history data, the amount of toner consumed to historically print the history document having the greatest similarity to the reference image is determined as the total consumption amount.
When the document to be printed has a plurality of pages, a reference image corresponding to each page is generated for each page, and then the toner amount consumed by the history document with the maximum similarity is determined for each reference page from the history data. The sum of the consumed toner amounts obtained for the respective reference images is taken as the total consumed amount of the document to be printed.
In a preferred embodiment, the first component of toner consumption consumed in the case of determining the printing target document may also be obtained based on historical data by using a first imaging model, and the process is similar to the process of determining the total consumption amount, and is not described herein again.
S110, determining a second threshold value according to the total consumption; the second threshold value is positively correlated with the total consumption and negatively correlated with the total number of pages contained in all the documents to be printed.
In a preferred embodiment, the ratio of the total consumed amount to the total number of pages may be used as the second threshold.
S112, judging whether the first component is larger than a second threshold value, if so, executing a step S114; if not, go to step S124.
S114: the target document is divided into a specified number of areas along the paper ejection direction at the time of printing.
In a preferred embodiment, the specified number may be a preset value. The regions are rectangular regions arranged in sequence along the paper discharge direction, and the sizes of the regions are the same. Wherein the specified number is inversely related to a paper feed step size of the printer.
S116, determining a consumption second component of the toner consumed when printing the area for each area; the second component of consumption is calculated by the following formula: qi=r1 i*r2 i+qi
In the formula, QiIs a second component of the consumption of the ith region; r is1 iIs a first weight, r in the case of a figure contained in a region1 iGreater than 1, r in the case of no graphics contained in the region1 iEqual to 1; r is2 iThe second weight is positively correlated with the time of the target document staying in the queue of the documents to be printed; q. q.siIs the amount of toner consumed in the case of printing the target document, predicted from the area ratio, qiIs positively correlated with the area ratio.
Since the second component calculated in this step is used for sorting, the area ratio can be directly used as q as long as the size of the second component of each region is distinguishedi。
The regions are sorted according to the consumed second component S118.
In a preferred embodiment, the regions may be sorted directly from large to small according to the second component and then printed in the sorted sequence.
In a preferred embodiment, the regions are sorted according to the second component from large to small to obtain a first sequence; determining a first page of a next file to be printed from a queue of the documents to be printed as a reference page; and according to the page content, determining an area with similarity greater than a third threshold value with the reference page from each area, and placing the area at the last position of the first sequence to obtain a second sequence. Thereafter, printing is performed in a second sequence.
And S120, printing the target document according to the sorted areas.
Illustratively, if a document is divided into: region 1, region 2, and region 3. The sorted regions are: region 2, region 3, region 1. The printer control system first feeds the paper to the location of area 2 and then prints area 2 and area 3. After that, the printer control system retracts the paper to the position of area 1, printing area 1. Finally, the printed paper is sent out of the printer.
S122, when the area ratio is not larger than a first threshold value, placing the target document at the last position in the queue of the documents to be printed to obtain the reordered queue of the documents to be printed; and determining a new target document from the reordered document queue to be printed.
And S124, printing the target document.

Another aspect of the present embodiment also provides a computer-readable storage medium storing a computer program, which is operable to execute an implementation process of the method for controlling a printer provided in fig. 1.
Another aspect of the present embodiment also proposes an electronic device as shown in fig. 4. On the hardware level, the electronic device may include a processor, an internal bus, a network interface, a memory, and a non-volatile memory, and may also include hardware required for other services. The processor reads the corresponding computer program from the nonvolatile memory into the memory and then runs the computer program to realize the process controlled by any one of the printers.
Of course, besides the software implementation, the present specification does not exclude other implementations, such as a logic device or a combination of software and hardware, and the like, that is, the execution subject of the following processing flow is not limited to each logic unit, and may also be a hardware or a logic device.
In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
