Description

Technical Field

[0001] The present invention relates to the field of printing technology, and in particular to a printing method, device, electronic equipment and computer-readable storage medium. Background Art

[0002] As catering companies move towards the Internet, they actively use the various information tools brought by the Internet and mobile Internet era to better serve consumers and develop their business better and faster. Internet catering refers to the various tools and platforms created by Internet companies for the catering industry, with the same purpose of improving efficiency, improving services, reducing costs and increasing revenue for catering companies.

[0003] Since the catering enterprise system needs to access a variety of Internet software products, such as ordering systems, takeaway systems, payment systems, and invoicing systems, there are often multiple heterogeneous information systems running on different software platforms at the same time. The data sources of these systems are independent and closed to each other, making it difficult to communicate, share, and integrate data between systems, thus forming an "information island". The invoicing system needs to print out the receipts required by users, but the data sources of different software products in the current system are isolated and closed to each other, and cannot be printed directly. And the various Internet software products need to establish additional data sharing channels, resulting in high printing costs. Summary of the invention

[0004] The object of the present invention is to provide a printing method, device, electronic device and computer-readable storage medium to improve the problem of high printing cost in the prior art.

[0010] In some embodiments of the present invention, the step of parsing the target image file to obtain the image includes: converting the target image file into a portable document format file. Extracting the image from the portable document format file, the image is a bitmap image.

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments.

[0025] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0026] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0027] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0028] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0029] Please see Figure 1 , Figure 1 A flowchart of a printing method provided by an embodiment of the present invention, the printing method comprises the following steps:

[0030] Step S110: Acquire the data to be printed, and convert the data to be printed into a universal printing file.

[0031] Before the step of obtaining the data to be printed, a configuration file can be obtained first and the interface can be configured according to the configuration file, and then the data can be monitored through the interface to obtain the data to be printed from the data. After the configuration is performed according to the configuration file, a connection can be established between the module that can generate the data to be printed through different standard specification interfaces so that the data can be transmitted. Then the data is monitored, and when the data to be printed that meets the conditions is monitored, the data to be printed can be obtained.

[0032] For example, the interface of the printer implementing the method is connected to the interface of a terminal device that can generate data to be printed. After the connection is established, the interface is configured according to the configuration file so that the printer can monitor the data to be printed generated by the terminal device through the interface to achieve data sharing among various devices.

[0033] It can be understood that the connection between the printer and the terminal device can be through a connecting cable or a wireless connection, wherein the wireless connection method can be a wireless LAN connection, a mobile network connection, a wireless Bluetooth connection, etc. The specific connection method can be determined according to the actual application scenario.

[0034] After the data to be printed is acquired, a universal printing file can be generated according to the drawing command corresponding to the data to be printed. The universal printing file includes a printing instruction part and a document data part, wherein the printing instruction part includes a header part, a page information part, a printing style instruction part and a group printer related information part, and the group printer related information part includes an output method instruction part, a group printer driver setting information part, the number of member printers, multiple member printer initiator names, multiple member printer driver setting information parts, etc.

[0035] Step S120: converting the general printing file into an image file and storing it in the storage module.

[0036] The image file can be a language image file, that is, a PS file, which can contain data such as images, texts, or a combination of images and texts. Therefore, the general printing file can be converted into an image file for storage, ensuring that the storage module can completely store the printing data.

[0037] When converting a general print file into an image file and storing it in a storage module, the image file can be preprocessed and labels can be obtained based on the preprocessing. For example, information such as the terminal device number, gateway address, authorization permission level, etc. corresponding to the image file can be obtained. In addition, there are keywords of the content in the image file, etc.

[0038] Step S130: searching the target image file from the storage module and printing it.

[0039] In the above implementation process, the universal printing file is universal, so after obtaining the data to be printed and converting it into a universal printing file, the applicability of the printing method can be improved. The universal printing file is then converted into an image file that can contain different data contents for storage to ensure the integrity of the data to be printed. Finally, the target image file that the user needs to print can be found from the storage module for printing.

[0040] In some embodiments of the present invention, when searching for a target image file from a storage module and printing, the target image file may be first obtained and parsed to obtain an image. Then, the image size is identified and the image after size identification is segmented. Finally, the image content in the segmented image is identified, and the characters in the image content are parsed and stored in a print storage unit for printing.

[0041] In the above implementation process, after finding the target image file in the storage module, it is necessary to first parse the target image file to obtain the image therefrom, and then pre-process the image to facilitate subsequent accurate identification of the content to be printed from the image.

[0042] When parsing the target image file, the target image file can be first converted into a portable document format file, and then the image is extracted from the portable document format file, and the image is a bitmap image. Since the target image file is a PS file, and the PS file is a vector image file, converting it into a portable document format file facilitates the subsequent process of extracting the image.

[0043] Portable Document Format (PDF) files can guarantee accurate colors and accurate printing effects for printers no matter which printer is used. That is to say, PDF files will faithfully reproduce every character, color and image of the original. And PDF files are an electronic file format that has nothing to do with the operating system platform. That is to say, PDF files are universal whether in Windows operating system, Unix operating system, or Apple's Mac OS operating system. This feature makes it an ideal document format for electronic document distribution and digital information dissemination on the Internet. PDF files can publish and release multimedia integrated information, and can encapsulate text, fonts, formats, colors, and graphics and images independent of equipment and resolution in one file. It can also contain electronic information such as hypertext links, sounds and dynamic images, and supports special files. It has high integration and security reliability. Therefore, after converting the target image file into a PDF file, the PDF file can be image recognized and text can be recognized.

[0044] As one implementation method, if the target image file includes a plain text image, text extraction can be performed directly, and the extracted text can be matched with text rules. After the match is passed, subsequent printing or storage operations can be performed.

[0045] In some embodiments of the present invention, the storage module also includes a tag that uniquely corresponds to each image file. When searching for a target image file from the storage module, the user's print request can be first obtained, and then the tag corresponding to the print request can be searched from the storage module to obtain the image file corresponding to the tag as the target image file according to the found tag. The accuracy of the search can be guaranteed by storing the tags that uniquely correspond to the image files. In addition, since the target image file is searched in all image files by directly searching the tags, the search efficiency can be greatly improved.

[0046] Among them, when searching for the target image file from the storage module, the target image file may be an encrypted file. Therefore, after finding the encrypted target image file, a decryption request can be sent to the terminal device corresponding to the encrypted target image file, and after receiving the response information corresponding to the decryption request, the encrypted target image file is decrypted according to the response information to avoid highly confidential data to be printed in the terminal device from being accidentally disclosed, thereby ensuring the security of the data to be printed.
