Description

Technical Field

[0001] This disclosure relates to the field of printing control technology, and in particular to a printer adaptive adjustment method, apparatus, electronic device, and readable storage medium. Background Technology

[0002] In high-security, classified enterprises and institutions, document printing requires monitoring and approval. This approval process typically utilizes a virtual printer to convert the document to be printed into an intermediate document with a standardized format, which is then submitted to the reviewer for approval. After approval, the intermediate document is sent directly to the physical printer for printing. Because this printing process adds the step of format conversion and uploading for approval, it is not possible to directly call the operating system's built-in printing services, such as the Print Spooler service in Windows. Instead, the intermediate document is sent directly to the physical printer. When physical printers come in various sizes, their corresponding print ranges also differ. This can cause scaling, distortion, or stretching of the printed document compared to the electronic document, resulting in poor print quality. Summary of the Invention

Based on this disclosure, those skilled in the art will understand that one aspect described herein can be implemented independently of any other aspect, and two or more of these aspects can be combined in various ways. For example, any number of aspects set forth herein can be used to implement the device and / or practice the method. Additionally, this device and / or method can be implemented using structures and / or functionalities other than one or more of the aspects set forth herein.

[0056] It should also be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this disclosure. The drawings only show the components related to this disclosure and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0057] Furthermore, specific details are provided in the following description to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that the described aspects can be practiced without these specific details.

[0058] Please see Figure 1 This disclosure provides a printer adaptive adjustment method, including the following steps:

[0059] S100: Obtain the first document to be printed through the unified interface of the virtual printer, and convert the first document into a first intermediate file.

[0060] This embodiment of the disclosure uses a pre-created virtual printer to uniformly receive all document print requests. When a user initiates the printing process for a first document, the document print request and the corresponding first document are first sent through the unified interface of the virtual printer. To facilitate subsequent approval and printing processes, this step can convert the first document from its original format to a first format to obtain a first intermediate file. Original formats include, but are not limited to, .doc, .xml, .pdf, etc., while first formats include, but are not limited to, .bw, .ai, .dwg, etc. Preferably, the first format is a vector graphic format, particularly EMF format. Those skilled in the art understand that vector graphic format files have the characteristic that scaling does not affect clarity, ensuring that the clarity of the display is not affected when the document is scaled and printed. By converting the first document with its original format into a first intermediate file with the first format, the amount of data can be reduced, caching pressure lowered, and transmission speed improved while retaining all valid information in the first document.

[0061] S200: Determine the target printer information corresponding to the first document.

[0062] In this embodiment, the target printer information is determined by a remote server searching for user information contained in the document print request to identify the pre-stored target printer information corresponding to that user information. This embodiment can pre-store mapping relationships between different user information and different printer information in the remote server. User information can be a unique identifier related to the user, and printer information can be a unique identifier related to the physical printer. By setting the mapping relationship between users and physical printers, targeted printing can be achieved. This avoids situations where multiple users use the same printer to print documents, resulting in too many print jobs and long waiting times. Furthermore, it clearly identifies the printer corresponding to each user's printed documents, preventing the problem of incorrect or missed paper.

[0063] The remote server can return one or more candidate printer information to the client based on a preset mapping relationship, meaning the user can choose which printer to use. It can be understood that if the remote server returns exactly one candidate printer, that candidate printer is determined as the target printer. If the remote server returns two or more candidate printers, the user selects one of the two or more candidate printers as the target printer.

[0064] S300: Obtain the first printing parameters of the target printer and the second printing parameters of the virtual printer; wherein, the first printing parameters are used to characterize the physical printing range of the target printer, and the second printing parameters are used to characterize the virtual printing range of the virtual printer set based on the first intermediate file.

[0065] The first printing parameters are related to the physical settings of the target printer, such as the physical printing area defined by the printhead position of the target printer, including a first width, a first height, a first left margin, and a first top margin. Here, the first width is the width of the physical printing area, the first height is the height of the physical printing area, the first left margin is the distance between the left edge of the physical printing area and the left edge of the paper, and the first top margin is the distance between the top edge of the physical printing area and the top edge of the paper. The second printing parameters are related to the virtual settings of the virtual printer, typically a default virtual printing area set based on historical experience, including a second width, a second height, a second left margin, and a second top margin. Here, the second width is the width of the virtual printing area, the second height is the height of the virtual printing area, the second left margin is the distance between the left edge of the virtual printing area and the left edge of the paper, and the second top margin is the distance between the top edge of the virtual printing area and the top edge of the paper.

[0066] S400: Adjust the second printing parameters according to the first printing parameters so that the virtual printing range and the physical printing range are matched.

[0067] Figure 2 This is a schematic flowchart illustrating the adjustment of the second printing parameters according to an embodiment of this disclosure. Figure 2 As shown, step S400 includes:

[0068] S410: Calculate the first aspect ratio of the target printer; the first aspect ratio is the ratio of the first width to the first height.

[0069] Assuming the first width is W1, the first height is H1, the first left margin is L1, and the first top margin is T1 in the first printing parameters, then the first aspect ratio R1 in this step is W1 / H1.

[0070] S420: Calculate the second aspect ratio of the virtual printer; the second aspect ratio is the ratio of the second width to the second height.

[0071] Assuming the second width is W2, the second height is H2, the second left margin is L2, and the second top margin is T2 in the second printing parameters, then the second aspect ratio R2 in this step is W2 / H2.

[0072] S430: Determine whether the second aspect ratio is the same as the first aspect ratio.

[0073] S440: Under the same conditions, adjust the second width, second height, second left margin and second top margin to the first width, first height, first left margin and first top margin respectively.

[0074] If R2 = R1, then let W2 = W1, H2 = H1, L2 = L1, and T2 = T1. Since the second aspect ratio is the same as the first aspect ratio in this step, we only need to adjust the second printing parameters to be exactly the same as the first printing parameters. Because the first intermediate file is in vector format, adjusting the scaling by modifying the second printing parameters will not affect the clarity of the printed first intermediate file.

[0075] S450: Adjustments are made according to the text or image content contained in the first intermediate file under different circumstances.

[0076] If R2≠R1, this embodiment can make adjustments based on the different content contained in the first intermediate file. A feature recognition model trained using artificial intelligence technology can be used to identify whether the first intermediate file contains text or graphics. This feature recognition model can be constructed from any existing form of artificial neural network. The coefficients of each neuron in the artificial neural network are trained using a large number of pre-labeled text or graphic features, and a final feature recognition model is obtained after sufficient iterative computation. The training process of this feature recognition model is prior art, and this embodiment will not elaborate on it further.

[0077] On the one hand, when the first intermediate file contains only text, slight changes to the aspect ratio of the text within a certain range will not affect the legibility of the text content. In this case, the first printing parameter can be directly replaced with the second printing parameter to achieve quick adjustment. On the other hand, when the first intermediate file contains only graphics, any change to the aspect ratio of the graphics may affect the accuracy of the graphics. Therefore, parameter adjustments need to be made while keeping the aspect ratio of the graphics unchanged to maximize the match between the second and first printing parameters. Specifically, this can include: adjusting the second width W2 to the first width W1, i.e., setting W2 = W1. Calculating the second updated height H2' of the virtual printing range based on the first width W1 and the second aspect ratio R2, where H2' = W1 / (W2 / H2). The above steps can ensure both the clarity and accuracy of the printed paper, regardless of whether the content is text or graphics.

[0078] S500: Print the first document using the target printer.

[0079] Through the above steps, this embodiment of the disclosure can adaptively set the virtual printing parameters of the virtual printer according to the physical printing parameters of the target printer, achieving consistency between the display effect of electronic documents and the display effect of paper documents. This embodiment of the disclosure is particularly suitable for application scenarios that require intermediate caching and review of print requests and cannot directly call the printing service built into the operating system, thereby enhancing the security level of electronic documents and preventing leaks caused by unauthorized printing.
