[0055] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0056] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0057] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0058] First of all, it should be noted that the present application proposes a scanning method to solve the problem in the prior art that functions such as printing, copying and scanning are usually achieved by setting multiple physical buttons on the printer or multiple virtual buttons on the touch screen of the printer, which makes the operation process more complicated and the degree of intelligence is low, thereby reducing the user experience.

[0059] Embodiment 1

[0060] See also Figure 1 , which is a scanning method in a first embodiment of the present invention, and is applied to a printer. A control knob is communicatively connected to the printer, and the control knob includes a knob and a display screen. The scanning method specifically includes steps S101 to S105:

[0061] S101, when it is detected that the knob is rotated to a first preset angle, controlling the printer to enter a scanning state, and sending a scanning state identifier to the display screen;

[0062] It should be noted that the scanning method provided in this embodiment is specifically applied to a preset control knob and a printer, wherein the control knob is a knob with a physical structure. In specific implementation, the control knob can be directly electrically connected to the above-mentioned printer. In other cases, the control knob can also communicate and interact with the above-mentioned printer through remote technologies such as Bluetooth and wireless LAN, which are all within the protection scope of this embodiment.

[0063] Furthermore, the control knob includes a knob arranged on the side and a display screen arranged on the side of the knob away from the printer, wherein the display screen is a touch screen, and when in use, the knob can be rotated relative to the display screen. Correspondingly, a controller is arranged inside the printer or inside the control knob, and the controller is electrically connected to the knob, the display screen and the printer respectively.

[0064] Therefore, in this step, when it is detected that the knob is rotated to the first preset angle, it means that the user has enabled the control knob. Specifically, the first preset angle can be an angle constant or an angle threshold, both of which are within the protection scope of this embodiment.

[0065] At the same time, the controller will control the printer to enter the scanning state, and correspondingly display the scanning state mark on the above-mentioned display screen.

[0066] S102, obtaining a scanning instruction sent by a user terminal, and generating a corresponding scanning task and a corresponding task identifier according to the scanning instruction;

[0067] In a specific implementation, when the user activates the control knob and controls the printer to enter a scanning state, the user can click a scan button on the display screen or send a scan command through a user terminal to enable the printer to complete a corresponding scanning operation.

[0068] Specifically, when the user scans by clicking on the display screen, after the user places the scanned document, the user only needs to enter the corresponding number of scans on the display screen, and the printer will scan the scanned document with the entered number of scans.

[0069] When the user sends a scanning instruction through the user terminal, a corresponding scanning task and a task identifier corresponding to the scanning task will be generated according to the data parameters contained in the scanning instruction, and the printer will perform a corresponding scanning operation according to the scanning task.

[0070] S103, transmitting the scanning task to the scanning queue of the printer, and determining the identification type of the task identification;

[0071] In a specific implementation, the controller adds the scanning task to the scanning queue of the above-mentioned printer, and determines the identification type of the above-mentioned task identification, determines the status of the scanning task according to the identification type, and further determines the position of the scanning task in the scanning queue.

[0072] S104, if the identification type of the task identification is a common type, controlling the printer to perform scanning processing according to the scanning queue;

[0073] In specific implementation, when the identification type of the task identification is a common type, it means that the corresponding scanning task is a regular scanning task. There is no need to adjust the position of the scanning task in the scanning queue, and the printer can be controlled to perform scanning operations according to the normal scanning queue.

[0074] S105: If the identification type of the task identification is an expedited type, the scanning task is adjusted to the first position of the scanning queue to control the printer to scan and process the scanning task preferentially.

[0075] In specific implementation, when the identification type of the task identifier is an expedited type, it means that the corresponding scanning task needs to be processed urgently, so the position of the scanning task in the scanning queue is adjusted to the first place in the queue, and the printer is controlled to scan and process the scanning task first.

[0076] It should be noted that the above implementation process is only to illustrate the feasibility of the present application, but this does not mean that the scanning method of the present application has only the above-mentioned implementation process. On the contrary, as long as the scanning method of the present application can be implemented, it can be included in the feasible implementation plan of the present application.

[0077] In summary, the scanning method in the above-mentioned embodiment of the present invention detects the rotation angle of the knob in real time, and when the knob is rotated to a first preset angle, controls the printer to enter a scanning state, and sends a scanning state identifier to a display screen for display. Furthermore, the scanning instruction sent by the user terminal is obtained in real time, and a corresponding scanning task and task identifier are generated according to the scanning instruction, and the processing order of the scanning task is determined according to the identification type of the task identifier, so that the user can realize the scanning function by rotating the knob. At the same time, the printer can also determine the order of scanning processing according to the task identifier, eliminating additional virtual buttons and physical buttons, thereby improving the intelligence of the scanning operation and correspondingly improving the user experience.

[0092] Specifically, when the user scans by clicking on the display screen, after the user places the scanned document, the user only needs to enter the corresponding number of scans on the display screen, and the printer will scan the scanned document with the entered number of scans.

[0093] When the user sends a scanning instruction through the user terminal, a corresponding scanning task and a task identifier corresponding to the scanning task will be generated according to the data parameters contained in the scanning instruction, and the printer will perform a corresponding scanning operation according to the scanning task.

[0096] S206, if the identification type of the task identification is a common type, controlling the printer to perform scanning processing according to the scanning queue;

[0097] In specific implementation, when the identification type of the task identification is a common type, it means that the corresponding scanning task is a regular scanning task. There is no need to adjust the position of the scanning task in the scanning queue, and the printer can be controlled to perform scanning operations according to the normal scanning queue.

[0098] S207, if the identification type of the task identification is an expedited type, adjusting the scanning task to the first position of the scanning queue, so as to control the printer to scan and process the scanning task preferentially;

[0099] In specific implementation, when the identification type of the task identifier is an expedited type, it means that the corresponding scanning task needs to be processed urgently, so the position of the scanning task in the scanning queue is adjusted to the first place in the queue, and the printer is controlled to scan and process the scanning task first.

[0103] In specific implementation, when the printer completes the scanning process of the above scanning task, it detects whether there is a scanning task with a task mark of the expedited type in the scanning queue, and automatically decides whether to expedite the process or enter the normal processing sequence according to the situation.

[0104] S210, if there is no scanning task with the task identification of the expedited type in the scanning queue, controlling the printer to perform scanning processing according to the scanning queue;

[0105] In specific implementation, when there is no scanning task with the task identification of the expedited type in the scanning queue, it means that there is no need to change the arrangement order of the scanning queue, and the printer can perform scanning processing according to the scanning queue.
