To more clearly demonstrate the method for setting up a receipt provided by the embodiments of this application, we will first introduce the application scenarios of the method for setting up a receipt provided by the embodiments of this application. Before introducing the application scenarios of the method for setting up a receipt provided by the embodiments of this application, we will first briefly introduce the implementation background of the embodiments of this application. With the development of cloud printing technology, cloud printing technology can print using various types of cloud printers. A cloud printer is a printing device connected via the Internet, which allows users to print from any device that supports an Internet connection without a direct physical connection or a traditional local area network (LAN) connection. Ordinary printers, on the other hand, typically connect to a local server via a network cable, and then the local server connects to a remote server. The core concept of cloud printing technology is to process and manage print jobs through cloud servers, thereby enabling a print experience anytime, anywhere, and across devices. When printing an order receipt, the cloud printer needs to parse the instruction set corresponding to the content of the order receipt sent by the server into the cloud printer's memory, and then execute the printing operation. However, currently, due to various limitations, most cloud printers can only print text when printing order receipts. Furthermore, for color printing of receipts, traditional Bluetooth and USB printing are usually the primary methods, while cloud printers can only print black and white text, severely limiting the application of cloud printers.

[0096] Based on this, this application provides a method for setting up printed receipts. This method allows the user to obtain multiple receipt images set by the merchant and the display position information corresponding to each receipt image through the receipt image editing area in the receipt template setting interface. Then, the multiple receipt images are sent to the cloud to obtain image identification data corresponding to each image. This generates a printed receipt template containing the image identification data based on the display position information. Finally, the printed receipt template is sent to the cloud, enabling the cloud to obtain the multiple receipt images based on the image identification data and instruct the printing equipment set up in the merchant's store to print a receipt displaying the multiple receipt images based on the printed receipt template. In this method, the printed receipt template can be set by the merchant, and the merchant can upload multiple images to the printed receipt through the multiple receipt image editing area. This allows the printing equipment to print a receipt with multiple images and text mixed together, solving the problem that printing equipment can only print receipts containing text, thereby improving the printing efficiency of receipts.

[0097] Another embodiment of this application provides a method for setting up receipt printing. This method allows merchants to select receipt printing color data using a color selection component in the receipt template setting interface. The receipt template, including the merchant's selected color data, is then sent to a cloud-based printing device server. The server converts the colors of the receipt data to the merchant's chosen color. When a receipt needs to be printed based on the merchant's template, a printing instruction set is generated using the template and the printable instance data provided by the front end. This instruction set is then sent to the printing device located in the merchant's store, enabling the device to print a receipt with the merchant's selected color. This method allows merchants to set up the receipt template and select the color data using the color selection component, enabling the printing device to print color receipts. This solves the problem of printing devices only being able to print black and white receipts, thereby improving printing efficiency.

[0098] The following describes in detail the application scenarios of the receipt setting method provided in this application, with reference to Figures 1-7. Taking Merchant A's receipt setting process as an example, please refer to Figure 1. Figure 1 is a schematic diagram of the first scenario of the receipt setting method provided in this application. After Merchant A enters the printer settings interface, the printer settings interface will display various receipt template types, such as customer copy, merchant copy, and kitchen copy. Taking the customer copy receipt template as an example, the merchant can click the edit button corresponding to the customer copy to edit it. After clicking the edit button, the second page will appear, as shown in Figure 2. Figure 2 is a schematic diagram of the second scenario of the receipt setting method provided in this application. The second page displays a receipt color selection button. Through the color selection button, the user can set the presentation color of the receipt to black or orange. The display area of ​​the second page is used to display the specific content presented on the receipt. The second page also includes a module editing button and a module sorting button. By triggering the module editing button, you can enter the print receipt template settings interface, which includes multiple receipt image editing areas. By triggering the module sorting button, you can adjust the order of the multiple receipt image editing areas in the print receipt template settings interface.

[0099] After clicking the module edit button, you will enter the third page, as shown in Figure 3. Figure 3 is a schematic diagram of the third scenario of the receipt printing setting method provided in this application. The third page is the receipt printing setting interface, which displays multiple receipt image editing areas for merchants to set receipt images. These include areas for displaying receipt type, merchant brand logo, estimated order delivery time, customer information, product information, promotional information, and merchant operations. Through these multiple receipt image editing areas, you can obtain multiple receipt images set by the merchant and the display position information for each receipt image. Taking the display of the merchant brand logo as an example, by triggering the edit button corresponding to the merchant brand logo area, you will enter the logo area editing page, as shown in Figure 4. Figure 4 is a schematic diagram of the fourth scenario of the receipt printing setting method provided in this application. On the logo area editing page, you can upload a store logo image in the image display area. When uploading, you can also crop the size of the store logo image and set its display shape. For example, you can set the store logo image to a rectangle or a square for display. Similarly, in the merchant operation area, merchants can upload custom images or choose from several pre-defined templates in the image template market. The merchant image upload settings interface is shown in Figure 5, which illustrates the fifth scenario of the receipt printing settings method provided in this application. Merchants can choose to edit the merchant operation area using a combination of images and text, images only, or text only. After uploading multiple images in the receipt printing template settings interface, the front-end sends these images to the cloud image storage. The image storage or front-end generates image identification data for each image, which can be a hash value or other identifier. This image identification data is then written into the receipt printing template, generating a receipt printing template containing image identification data based on the display location information of multiple receipt images. This template is then sent to the cloud-based printing device server. When a receipt needs to be printed based on the template, the printing device server obtains the printable instance data from the front-end. This printable instance data includes customer information, such as the customer's name, address, and contact information. The printing device server retrieves multiple receipt images from the image storage terminal based on the image identification data. Then, the printing device server generates a printing instruction set based on the multiple receipt images, the printable instance data provided by the front end, and the print receipt template. The printing instruction set is then sent to the printing devices set up in the store operated by the merchant, so that the printing devices print receipts displaying multiple receipt images according to the printing instruction set.

[0100] The above is an overall scenario description of the receipt setting method provided in this application embodiment. The following, in conjunction with Figures 6 and 7, describes the process in this application where the merchant sets up a receipt template, and the front end sends the receipt template to the cloud-based printing device server so that the printing device server, based on the receipt template, instructs the printing device set up in the merchant's store to print a receipt displaying multiple receipt images. The front end 10-1, which sets up the receipt template, executes step S701: Displaying a receipt image editing area for the merchant to set receipt images in the receipt template setting interface; then, executing step S702: Obtaining the multiple receipt images set by the merchant and the display position information corresponding to each receipt image through the multiple receipt image editing areas. Next, step S703 is executed: the multiple receipt images are sent to the image storage terminal 10-2 in the cloud; step S704: image identification data corresponding to the multiple receipt images is obtained; step S705: a print receipt template containing image identification data based on the display location information is generated; then, step S706 is executed: the print receipt template set by the merchant is sent to the printing device server 10-3 in the cloud. Step S707: the front-end 10-1 of the print receipt template sends the instance data to be printed to the printing device server 10-2. Then, step S708 is executed: the printing device server 10-3 obtains multiple receipt images corresponding to the printing receipt template from the image storage terminal 10-2 in the cloud based on the image identification data of the multiple receipt images in the printing receipt template; then, step S709 is executed: when a receipt needs to be printed according to the printing receipt template, the printing device server 10-3 generates a printing instruction set based on the multiple receipt images, the printable instance data provided by the front end 10-1, and the printing receipt template; then, step S710 is executed: the printing device server 10-3 sends the printing instruction set to the printing device 10-4 set up in the store operated by the merchant. Finally, after receiving the printing instruction set, the printing device 10-4 executes step S711: prints the receipt displaying the multiple receipt images according to the printing instruction set.

[0101] The above is the overall implementation process of the receipt setting method provided in this application embodiment. This method obtains multiple receipt images set by the merchant and the display position information corresponding to each receipt image through the receipt image editing area in the receipt template setting interface. Then, it sends the multiple receipt images to the cloud to obtain image identification data corresponding to the multiple receipt images, thereby generating a receipt template containing image identification data based on the display position information. Finally, it sends the receipt template to the cloud, enabling the cloud to obtain the multiple receipt images according to the image identification data and, based on the receipt template, instruct the printing equipment set in the merchant's store to print a receipt displaying the multiple receipt images. In this method, the receipt template can be set by the merchant, and the merchant can upload multiple images to the receipt through the multiple receipt image editing area. This allows the printing equipment to print receipts with multiple images and text mixed together, solving the problem that printing equipment can only print receipts with text, thereby improving the printing efficiency of receipts.

[0102] In another implementation scenario of the receipt setting method provided in this application, a print color selection component for merchants to select the print color of the receipt can also be displayed in the print receipt template setting interface. Merchants can select the print color data of the receipt through the print color selection component, and send the print receipt template including the print color data selected by the merchant to the printing device server in the cloud. The printing device server then converts the color of the receipt data to be printed in the receipt to the color selected by the merchant based on the print color data selected by the merchant. When it is necessary to print a receipt according to the print receipt template set by the merchant, a print instruction set is generated based on the print receipt template and the print instance data provided by the front end. The print instruction set is sent to the printing device set in the store operated by the merchant, so that the printing device prints a receipt with the print color of the receipt data as selected by the merchant according to the print instruction set. In this method, the receipt template can be set by the merchant, and the merchant can select the receipt printing color data through the printing color selection component, so that the printing device can print color receipts, solving the problem that the printing device can only print black and white receipts, thereby improving the printing efficiency of receipts.

[0103] Figures 1, 2, 3, 4, 5, 6, and 7 described above illustrate one application scenario of the receipt setting method of this application. The embodiments of this application do not specifically limit the application scenario of the receipt setting method. The above-described application scenario of the receipt setting method is merely one embodiment of the application scenario of the receipt setting method provided in this application. The purpose of providing this application scenario embodiment is to facilitate understanding of the receipt setting method provided in this application, and is not intended to limit the receipt setting method provided in this application. Other application scenarios of the receipt setting method in this application will not be described in detail.

[0104] First Embodiment

[0105] This embodiment provides a method for setting up receipt printing, which will be described below with reference to Figure 8. The applicable scenarios for this receipt printing setting method can be referred to the above scenario embodiments. For some examples of this embodiment, please refer to the above scenario embodiments.

[0106] Please refer to Figure 8, which is a flowchart of the method for setting up a printed receipt provided in the first embodiment of this application.

[0107] The method for setting up a printed receipt according to this application is applied to the front end for setting up a printed receipt template, and includes the following steps.

[0108] Step S801: In the receipt template settings interface, display the receipt image editing area for merchants to set receipt images.

[0109] This step displays the receipt image editing area for merchants to set receipt images in the receipt template settings interface. In this embodiment, taking order receipts printed by catering merchants as an example, merchants can customize the order receipts to be printed through the front-end of the receipt template settings. For example, merchants can upload multiple images through the receipt image editing area displayed in the receipt template settings interface, and can also enter text in the text editing area of ​​the receipt template and adjust the font size as needed. Specifically, displaying the receipt image editing area for merchants to set receipt images in the receipt template settings interface includes: displaying multiple receipt image upload entry components for merchants to upload multiple receipt images in the receipt template settings interface. Please refer to Figure 3. The multiple receipt image upload entry components displayed in the receipt template settings interface for merchants to upload multiple receipt images include: a merchant logo image upload entry component displayed in the merchant logo settings area for merchants to upload merchant logo images, and a merchant operation image upload entry component displayed in the merchant operation settings area for merchants to upload merchant operation images.

[0110] It should be noted that each receipt image upload component supports uploading only one image. For example, referring to Figure 4, the merchant logo image upload component in the merchant logo settings interface (the image display area in Figure 4 is also an image upload component) only supports uploading one merchant logo image. Referring to Figure 5, in the merchant operations display area, merchants can upload images through the merchant operations image upload component (the image upload area in Figure 5). Since the receipt template settings interface contains multiple receipt image editing areas, merchants can set multiple receipt images for display through multiple image upload components in these areas. In specific implementation, before displaying the receipt image editing area for merchants to set receipt images in the receipt template settings interface, the receipt template settings interface is first displayed on the front end. Specifically, the front end can respond to the detection of a trigger operation in the merchant center of a mini-program or official account, displaying the merchant center service list; and respond to the detection of a trigger operation for smart hardware in the merchant center service list, displaying the receipt template settings interface.

[0111] Step S802: Obtain multiple receipt images set by the merchant and the display position information corresponding to each receipt image through multiple receipt image editing areas.

[0112] This step is used to obtain multiple receipt images set by the merchant and the display position information corresponding to each receipt image through multiple receipt image editing areas. It should be noted that in the front-end receipt template settings interface, merchants can set multiple receipt images for display on the receipt through multiple image upload entry components in multiple receipt image editing areas. Since the receipt images are displayed in the receipt image editing areas, once the location of the receipt image editing area is determined, the display position of the receipt image in each corresponding receipt image editing area is also determined. In specific implementation, the display position information corresponding to each receipt image is obtained in the following way: In response to detecting a trigger operation on the receipt display position in the settings page, a receipt image editing area for editing the display position is displayed, wherein a display position includes at least one receipt image; In response to detecting an image editing operation on the editing area of ​​the receipt image, the receipt display position information where the image editing operation is located is obtained, the display position information includes the display position and the editing area position. It should be noted that in the settings page, after the front-end detects a trigger operation on the receipt display position, it will enter another page. This page displays the receipt image editing area for editing the display position. Furthermore, a display position can include one or more receipt images. After the front-end detects an image editing operation on the editing area of ​​the receipt image, it can obtain the receipt display position information where the image editing operation is located. This display position information includes not only the display position of the receipt image but also the location of the editing area used to edit the receipt image. Triggering the edit button at this editing area location will take you to the editing page (for example, the interface shown in Figure 4 or Figure 5). Referring to Figure 2, in the settings page, after the merchant triggers the "Module Sorting" button, they enter multiple receipt image editing areas (i.e., the interface corresponding to Figure 3). This interface can be used to set the position of each area (module) in the receipt image editing area on the receipt. Once the display position of a module on the receipt is determined, since the receipt image is set within a module, the display position information corresponding to each receipt image can be obtained based on the module's display position information.

[0113] In this embodiment, merchants can select and upload multiple images by triggering multiple image upload entry components. There are two ways for merchants to upload images: one is custom upload, where merchants can freely upload images that meet their needs. These images can be user-defined photos used to identify merchant characteristics, such as images used to identify promotional information. The other method is for merchants to select a fixed image template from the image template library and then edit based on that template. Therefore, the image can also be generated using an image template, such as one for inviting positive reviews, adding the store to favorites, displaying the merchant's phone number, or announcing member days. When selecting images through an image template, merchants can also edit the images and text on the template to better meet their usage needs.

[0114] Step S803: Send the multiple receipt images to the cloud.

[0115] This step involves the front-end sending multiple receipt images uploaded by the merchant to the cloud. Specifically, the cloud includes a printing device server and an image storage terminal. Sending the multiple receipt images to the cloud specifically means sending them to the image storage terminal.

[0116] Step S804: Obtain the image identification data corresponding to the multiple receipt images.

[0117] This step involves the front-end sending multiple receipt images uploaded by the merchant to the image storage terminal, and then obtaining image identification data corresponding to these receipt images. It should be noted that the image identification data can be generated either by the front-end receiving the multiple receipt images uploaded by the merchant and sending them to the cloud along with the image identification data, or by the image storage terminal receiving the multiple receipt images uploaded by the merchant and then generating image identification data corresponding to each receipt image based on these images. This image identification data can specifically be a hash value, an index, or other image data—any data that can identify the multiple receipt images set by the merchant. In this embodiment, the generation of image identification data at the image storage terminal is described as an example. Specifically, the hash value corresponding to the multiple receipt images returned by the image storage terminal is obtained. This hash value is used to identify the multiple receipt images in the image storage terminal.

[0118] Step S805: Generate a printable receipt template containing image identifier data based on the displayed location information.

[0119] This step is used to generate a print receipt template, which includes display position information for multiple receipt images and image identification data. Since the image identification data includes hash values, generating a print receipt template containing image identification data based on the display position information includes: generating a print receipt template containing hash values ​​based on the display position information.

[0120] Step S806: Send the printed receipt template to the cloud so that the cloud can obtain the multiple receipt images according to the image identification data, and print receipts displaying the multiple receipt images on the printing equipment set in the store operated by the merchant based on the printed receipt template.

[0121] This step involves the front end sending a printed receipt template to the cloud, enabling the cloud to instruct the printing equipment set up in the merchant's store to print receipts displaying the multiple receipt images based on the printed receipt template. Specifically, sending the printed receipt template to the cloud means sending it to the printing equipment server. When the cloud obtains the multiple receipt images based on the image identification data, it specifically obtains the multiple receipt images from the image storage terminal based on the hash values ​​of the multiple receipt images in the printed receipt template set by the merchant. Obtaining the multiple receipt images from the image storage terminal based on the hash values ​​of the multiple receipt images in the printed receipt template set by the merchant includes: sending an image retrieval request message to the image storage terminal requesting to obtain the image corresponding to the multiple receipt images, the image retrieval request message including the hash values ​​corresponding to the multiple receipt images; and obtaining the multiple receipt images returned by the image storage terminal.

[0122] After obtaining multiple receipt images based on image identification data, the cloud-based printing server will print receipts displaying these multiple images using printing receipt templates set up in the merchant's store. Specifically, when a receipt needs to be printed according to the merchant's set printing receipt template, a printing instruction set is generated based on the multiple receipt images, the printable instance data provided by the front end, and the printing receipt template. This printing instruction set is then sent to the printing devices set up in the merchant's store, enabling the printing devices to print receipts displaying the multiple receipt images according to the printing instruction set. In practice, after the front-end detects the merchant's confirmation of uploaded image, it sends the uploaded image to the cloud image storage terminal for storage and sends the printed receipt template set by the merchant to the cloud printing device server for storage. The printing device server then retrieves multiple receipt images from the image storage terminal based on the image identifier data of the multiple receipt images in the merchant's printed receipt template. When a receipt needs to be printed according to the merchant's printed receipt template, a printing instruction set is generated based on the multiple receipt images, the printable instance data provided by the front-end, and the printed receipt template. Alternatively, the front-end can detect the merchant's confirmation of uploaded image only after detecting the confirmation of the merchant's printed receipt settings. In practice, the front-end also needs to obtain the printable instance data, specifically the order data sent by the order server. In practical applications, the printable instance data provided by the front-end can be obtained from the order data sent by the order server. This printable instance data can include the recipient's name, contact information, delivery address, and specific food items. The receipt template can have commonly used fields set in a fixed format, such as merchant address, order date, and font size. It's important to note that before the printing server generates the print instruction set, the front-end sends print instructions to the printing server. These instructions include the instance data to be printed. Specifically, when the printing server generates the print instruction set based on multiple receipt images, the instance data provided by the front-end, and the receipt template, it responds to the print instructions by generating the print instruction set. The printing server then sends the print instruction set to the printing device, causing the printing device to print a receipt displaying multiple receipt images, recipient information, and food details.

[0123] As one embodiment, on the cloud-based image storage terminal, the image identification data can be the image's hash value. The front-end can write the hash values ​​corresponding to multiple receipt images into the receipt template set by the merchant, serving as the image identification data for the multiple receipt images. Specifically, after the front-end sends multiple receipt images to the cloud-based image storage terminal, it receives the hash values ​​corresponding to the multiple receipt images returned by the image storage terminal. These hash values ​​are used to identify the multiple receipt images in the image storage terminal. The front-end writes these hash values ​​into the receipt template set by the merchant, serving as the image identification data for the multiple receipt images. When the front-end retrieves multiple receipt images from the image storage terminal based on the image identification data of the multiple receipt images in the receipt template set by the merchant, it specifically obtains the hash values ​​corresponding to the multiple receipt images from the receipt template set by the merchant and sends an image retrieval request message to the image storage terminal requesting the retrieval of the multiple receipt images. This image retrieval request message includes the hash values ​​corresponding to the multiple receipt images, thereby obtaining the multiple receipt images returned by the image storage terminal.

[0124] As one embodiment, on the cloud-based image storage terminal, the image identification data can be the image's hash value. The front-end can also set image indexes in the merchant's printed receipt template to identify multiple receipt images, serving as the image identification data for these multiple receipt images. In specific implementation, after the front-end sends multiple receipt images to the cloud-based image storage terminal, the front-end receives the hash values ​​corresponding to the multiple receipt images returned by the image storage terminal. These hash values ​​are used to identify the multiple receipt images in the image storage terminal. The front-end sets image indexes in the merchant's printed receipt template to identify the multiple receipt images, serving as the image identification data for these multiple receipt images. Simultaneously, the front-end establishes a correspondence between the image indexes and the corresponding hash values ​​for the multiple receipt images, and sends this correspondence to the printing device server. When the frontend retrieves multiple receipt images from the image storage based on the image identifier data of multiple receipt images in the receipt template set by the merchant, it specifically obtains the image index from the receipt template, and then obtains the hash value corresponding to each receipt image based on the correspondence between the image index and the hash value of the corresponding receipt image. Next, the frontend sends an image retrieval request message to the image storage, which includes the hash value of the corresponding receipt image, thereby obtaining the multiple receipt images returned by the image storage.

[0125] As one embodiment, on the cloud-based image storage terminal, the image identification data can be the image's hash value. The front-end can write the hash values ​​corresponding to multiple receipt images into the receipt template set by the merchant, serving as the image identification data for multiple receipt images. In practical applications, the image index used to identify multiple receipt images can also be set on the printing device server. Specifically, after the front-end sends multiple receipt images to the cloud-based image storage terminal, the front-end obtains the hash values ​​corresponding to the multiple receipt images returned by the image storage terminal. These hash values ​​are used to identify the multiple receipt images in the image storage terminal. The front-end writes the hash values ​​corresponding to the multiple receipt images into the receipt template set by the merchant, serving as the image identification data for multiple receipt images. The printing device server also sets up an image index to identify multiple receipt images. Simultaneously, the printing device server establishes a correspondence between the image index and the hash values ​​corresponding to the multiple receipt images, and replaces the hash values ​​corresponding to the multiple receipt images in the receipt template set by the merchant with the image index. When the front-end retrieves multiple receipt images from the image storage based on the image identifier data of multiple receipt images in the receipt template set by the merchant, the front-end specifically obtains the image index from the receipt template set by the merchant, obtains the hash value corresponding to the multiple receipt images according to the correspondence between the image index and the hash value corresponding to the multiple receipt images, and sends an image retrieval request message to the image storage to request the multiple receipt images. The image retrieval request message includes the hash value corresponding to the multiple receipt images, thereby obtaining the multiple receipt images returned by the image storage.

[0126] In this embodiment, the front-end also obtains the link addresses of the multiple receipt images returned by the image storage terminal according to the image acquisition request message. Obtaining the multiple receipt images returned by the image storage terminal includes: downloading the multiple receipt images from the image storage terminal according to the link addresses of the multiple receipt images. It should be noted that after the front-end sends an image acquisition request message to the image storage terminal to request multiple receipt images, the front-end obtains the link addresses of the multiple receipt images returned by the image storage terminal according to the image acquisition request message. Specifically, when obtaining the multiple receipt images returned by the image storage terminal, the front-end downloads the multiple receipt images from the image storage terminal according to the link addresses of the multiple receipt images. The link address of the image can specifically be the Uniform Resource Locator (URL) of the image.

[0127] In specific implementation, if the receipt image is a QR code image containing a QR code, the QR code in the QR code image is identified to obtain the string information corresponding to the QR code; the string information is sent to the cloud so that the QR code image can be generated based on the string information when needed. It should be noted that the source of the QR code image can be either the original uploaded image or a cropped image. After the string information is sent to the cloud, the QR code image can be generated based on the string information, either when the cloud-based printing device server needs to obtain the QR code image or when the printing device itself needs to obtain the QR code image.

[0128] In practical applications, the front-end also needs to detect whether the color schemes of the multiple receipt images uploaded by the merchant match the receipt printing color scheme selected by the merchant. If not, the front-end converts the colors of the uploaded receipt images according to the merchant's selected receipt printing color scheme, obtaining multiple color-converted receipt images, and displays these converted images on the front-end for the merchant to view. Specifically, when the front-end sends the multiple receipt images to the image storage terminal, it sends the color-converted receipt images directly to the image storage terminal. For example, if the merchant uploads images with colors including black, white, red, and orange, and the merchant selects black, white, and orange for receipt printing, the front-end will convert the uploaded image colors to black, white, and orange according to the merchant's selected receipt printing color scheme. As another example, if the merchant uploads a pure black image, but the merchant sets the receipt color to orange, the receipt will ultimately be converted to orange. It should be noted that the receipt printing color scheme selected by the merchant is a color scheme supported by the printing device.

[0129] In this embodiment, the front end also adjusts the color and size of the images. Specifically, it processes the colors of multiple receipt images uploaded by the merchant based on an image color processing strategy to obtain multiple receipt images with color processing that meet preset color requirements; and it adjusts the size of multiple receipt images uploaded by the merchant based on an image size processing strategy to obtain multiple receipt images with adjusted sizes within a preset image size range. It should be noted that when using a cloud printer to print order receipts, the memory occupied by the instruction set corresponding to the order receipt content generally does not exceed the storage capacity of the cloud printer's memory. When the instruction set corresponding to the order receipt content exceeds the storage capacity of the cloud printer's memory, the cloud printer may experience lag or crashes, resulting in order receipt printing failure. Therefore, to avoid generating excessively large instruction sets, images require color conversion, and the size of a single image must not exceed 12KB. Generally, the entire order receipt content, after being converted into a printing instruction set, should not occupy more than 60KB of memory. Of course, different printing devices have different memory requirements for the printing instruction set; it might be that the printing instruction set should not occupy more than 140KB of memory, or other requirements. In practice, the printing content of the order receipt should be adjusted according to the specific memory requirements of the printing device to ensure that the corresponding printing instruction set meets the printing requirements of the printing device. Similarly, the image size also needs to be adjusted. The image size requirements are: the aspect ratio of a cropped square image is 1:1, and the aspect ratio of a cropped rectangular image is 1.6:1.

[0130] The above is the overall process of the receipt setting method provided in this application embodiment. This method obtains multiple receipt images set by the merchant and the display position information corresponding to each receipt image through the receipt image editing area in the receipt template setting interface. Then, it sends the multiple receipt images to the cloud to obtain image identification data corresponding to the multiple receipt images, thereby generating a receipt template containing image identification data based on the display position information. Finally, it sends the receipt template to the cloud, enabling the cloud to obtain the multiple receipt images according to the image identification data and, based on the receipt template, instruct the printing equipment set in the merchant's store to print a receipt displaying the multiple receipt images. In this method, the receipt template can be set by the merchant, and the merchant can upload multiple images to the receipt through the multiple receipt image editing area. This allows the printing equipment to print receipts with multiple images and text mixed together, solving the problem that printing equipment can only print receipts with text, thereby improving the printing efficiency of receipts.

[0131] Second Embodiment

[0132] Corresponding to the first embodiment, the second embodiment of this application provides a receipt printing method applied to a cloud-based printing device server. The parts in the second embodiment that are the same as those in the first embodiment will not be described again; please refer to the relevant parts of the first embodiment for details.

[0133] Please refer to Figure 9, which is a flowchart of the receipt printing method provided in the second embodiment of this application.

[0134] The receipt printing method of this application embodiment is applied to a cloud-based printing device server and includes the following steps: Step S901: Obtain a receipt template set by the merchant. The receipt template includes image identification data corresponding to multiple receipt images and display position information corresponding to each receipt image. Step S902: Based on the image identification data of the multiple receipt images in the receipt template, obtain multiple receipt images corresponding to the receipt template from a cloud-based image storage terminal. The multiple receipt images are provided to the image storage terminal by the front-end that sets the receipt template. Step S903: When it is necessary to print a receipt according to the receipt template, print a receipt displaying the multiple receipt images on the printing device set in the store operated by the merchant, according to the instructions of the receipt template.

[0135] In specific implementation, the printing equipment set up in the store operated by the merchant, according to the printed receipt template, prints a receipt displaying the multiple receipt images. This includes: generating a printing instruction set based on the multiple receipt images, the printable instance data provided by the front end, and the printed receipt template; sending the printing instruction set to the printing equipment set up in the store operated by the merchant, so that the printing equipment prints a receipt displaying the multiple receipt images according to the printing instruction set. It should be noted that when the printing equipment server receives a print task sent by the front end, it determines the print template based on the merchant identification information of the merchant to which the front end belongs. Specifically, in response to the receipt printing instruction sent by the front end, it obtains the merchant identification information of the merchant to which the front end belongs; based on the merchant identification information, it obtains the printed receipt template and multiple receipt images corresponding to the merchant identification information.

[0136] In this embodiment, the printing device can specifically be a cloud printer, and the printing device server can specifically be the server corresponding to the cloud printer. After obtaining the print receipt template set by the merchant, multiple receipt images, and the print instance data provided by the front end, the printing device server needs to first convert the print receipt data into an instruction set that the cloud printer can recognize, and then send the instruction set to the cloud printer. After receiving the instruction set sent by the server, the cloud printer can cache it and recognize the print characters in the instruction set, thereby printing the print data. The instruction set can specifically be the ESC instruction set, which is a simplified version of the ESC print control command. Currently, most order receipt printing uses the ESC instruction set. A significant feature of the ESC instruction set is that a large portion of its instructions are a string of codes starting with the ESC control character. Therefore, after obtaining the print receipt, the print receipt data needs to be converted into the corresponding instruction set. There is a correspondence between the print receipt data and the corresponding instruction set. Based on this correspondence, a print instruction set corresponding to the print receipt data can be generated.

[0137] In practice, the printing device server can generate and send printing instruction sets to the printing device in various ways. The first method is for the printing device server to generate and send printing instruction sets based on the actual service scenario. As one example, after receiving multiple receipt images from the printing device server, the printing device converts these images into a printing device image index. Specifically, the printing device server obtains multiple receipt images corresponding to the printed receipt template from the image storage end and sends these images to the printing device. The printing device then stores these images, marks them with an index (as the printing device image index), and sends it to the printing device server. The printing device server receives the image index used to identify the multiple receipt images in the printing device. When generating the printing instruction set based on the multiple receipt images, the printable instance data provided by the front end, and the printable receipt template, the printing device server specifically generates the printing instruction set based on the printing device image index, the printable instance data provided by the front end, and the printable receipt template. When a printing device prints according to a print instruction set, it first parses the print instruction set and replaces the print device image index with the image originally stored by the printing device that corresponds to the print device image index. As one embodiment, after the printing device server obtains multiple receipt images, it converts these images into a print device image index and then sends it to the printing device. Specifically, after obtaining multiple receipt images corresponding to the print receipt template from the image storage terminal, the printing device server sets an image index on the printing device to identify the multiple receipt images, and sends the multiple receipt images and the print device image index to the printing device. When the printing device server generates a print instruction set based on the multiple receipt images, the printable instance data provided by the front end, and the print receipt template, it specifically generates the print instruction set based on the print device image index, the printable instance data provided by the front end, and the print receipt template. When the printing device prints according to the print instruction set, it first parses the print instruction set, obtains the image corresponding to the print device image index from the printing device server, and replaces the print device image index with this image.

[0138] The second method involves the printing server sending multiple cached receipt images to the printing device. The reason for caching the images first is that when an order receipt contains both images and text, the corresponding print instruction set for the images can become too large, easily causing printing failures or slowdowns. Therefore, the printing server first sends the images to the printing device for storage and indexing. As one implementation, the printing device sets an image print instruction set index. Specifically, after the printing server obtains multiple receipt images corresponding to the receipt template from the image storage, it generates an image print instruction set based on these images and sends the image print instruction set to the printing device. Upon receiving the image print instruction set, the printing device marks the image print instruction set with an index, which serves as the image print instruction set index, and then sends it to the printing server. The printing device server receives the image printing instruction set index sent by the printing device. When generating a printing instruction set based on multiple receipt images, printable instance data provided by the front end, and the printable receipt template, specifically, it generates a text printing instruction set based on the printable instance data and printable receipt template, establishing a correspondence between the image printing instruction set index and the text printing instruction set. When sending the printing instruction set to the printing device located in the merchant's store, specifically, it sends the text printing instruction set to the printing device and also sends the correspondence between the image printing instruction set index and the text printing instruction set to the printing device. As one embodiment, the printing device server sets the image printing instruction set index by obtaining multiple receipt images corresponding to the printable receipt template from the image storage terminal and generating an image printing instruction set based on these multiple receipt images. In this embodiment, the printing device server sets an image printing instruction set index for the image printing instruction set and sends the image printing instruction set and the image printing instruction set index to the printing device. When generating a print instruction set based on multiple receipt images, printable instance data provided by the front end, and printable receipt templates, specifically, a text print instruction set is generated based on the printable instance data and printable receipt templates provided by the front end, establishing a correspondence between image print instruction set indexes and text print instruction sets. When sending the print instruction set to the printing equipment set up in the merchant's store, specifically, the text print instruction set is sent to the printing equipment, along with the correspondence between the image print instruction set indexes and the text print instruction sets.

[0139] In the second method of generating print instruction sets, after obtaining the image print instruction set index, the printing device can know which image print instruction set corresponds to the print instruction set sent by the printing device server, and then the printing device prints the receipt according to the image print instruction set and the print instruction set.

[0140] The third method involves real-time encoding and issuing print command sets while the receipt is previewed on the front end. In practice, if the printing device server receives the preview print command from the front end, it generates an image print command set based on multiple receipt images, a receipt text print command set based on the receipt template, and obtains the print command set from both the image and text sets. This print command set is then sent to the printing device, which prints the receipt according to the command set. It should be noted that the printing device server generates the print command set by calling the Napos SDK.

It should be noted that after the front-end receives multiple receipt images uploaded by the merchant, it needs to determine whether the color of the image corresponds to the color type of the receipt printing color data selected by the merchant. If it does, the image can be sent directly to the cloud image storage. If not, the image color needs to be converted according to the color type of the receipt printing color data selected by the merchant.

[0155] This application provides a method for setting up receipt printing. This method allows merchants to select receipt printing color data using a color selection component in the receipt template settings interface. The receipt template, including the merchant's selected color data, is then sent to a cloud-based printing device server. The server converts the colors of the receipt data to the merchant's chosen color. When a receipt needs to be printed based on the merchant's template, a printing instruction set is generated using the template and the printable instance data provided by the front end. This instruction set is then sent to the printing device located in the merchant's store, enabling the device to print a receipt with the merchant's selected color. This method allows merchants to set up the receipt template and select the color data using the color selection component, enabling the printing device to print color receipts. This solves the problem of printing devices only being able to print black and white receipts, thus improving printing efficiency.
