Referring to FIG. 1 , FIG. 1 is a schematic flowchart of a method for printing a receipt based on a webpage according to an embodiment of the present application. As shown in Figure 1, the method includes the following steps:

Step 101: Based on a preset static printing template, adjust the layout of the web page to be printed, and squeeze the header area and the footer area of the web page to be printed out of the text printing area.

In this embodiment of the present application, a static printing template may be preconfigured, and the static printing template generally corresponds to printing paper of a specific size (eg, A4 paper). When configuring the static print template, you can configure the static print template according to the layout and style of the business receipt to be printed, such as setting the display position of the title, field, etc. in the static print template, and configuring the When printing a template statically, ensure that the template content does not exceed the size of the corresponding printing paper. In the embodiment of the present application, the main function of the configured static printing template is to remove the page area and the footer area in the web page, and to ensure that the display format of the retained body content is normal.

In this embodiment of the present application, when printing the web page to be printed, the layout of the web page to be printed may be adjusted based on the above-mentioned pre-configured static printing template, and the header area and the footer area of the web page to be printed may be extruded. The text printing area, that is, the page area and the footer area in the web page to be printed are not reflected in the actually printed page.

During specific implementation, the to-be-printed web page may be elongated based on the page area width and the footer area width indicated by the static printing template, so as to squeeze the page area and footer area of the to-be-printed web page out of the text printing area .

Exemplarily, when the static printing template is preconfigured, the width of the page area to be extruded and the width of the footer area may be configured. Correspondingly, when adjusting the layout of the to-be-printed web page based on the static printing template, the to-be-printed web page can be elongated in the vertical direction by the sum of the page area width and the footer area width, so that the page in the to-be-printed web page can be extended. The area and footer area extrude the body print area that would be printed.

It should be noted that, in this embodiment of the present application, when a new printing demand exists, a corresponding static printing template may be configured for the new printing demand, so as to print out a service that meets the printing demand through the configured static printing template receipt.

Step 102: Based on a preset page margin, adjust the text content retained in the text printing area.

After the header area and the footer area in the web page to be printed are extruded from the text printing area, the text content retained in the text printing area can be adjusted to restore the display size of the text content.

During specific implementation, the text content retained in the text printing area may be retracted based on a preset page margin to ensure that the display size of the proof content is normal. In this embodiment of the present application, in order to extrude the header area and footer area in the web page to be printed out of the actual printed text printing area, the web page to be printed is vertically elongated based on the width of the header area and the footer area. , and with the longitudinal extension of the web page to be printed, the text content retained in the web page to be printed will also be elongated in the longitudinal direction, in order to ensure that the text content retained in the text printing area can be printed in a normal size In this embodiment of the present application, a vertical page margin can be set, and the page margin can be equal to the width and value of the header area and the page footer area, and further, the text printing area can be retracted and adjusted based on the page margin, thereby The text content retained in the text printing area can be displayed and printed in normal size.

Step 103: Configure a print function, and print the text content retained in the text print area based on the print function.

Printing requirements for business receipts. Configure the browser object model, which can support printing the text printing area of the web page to be printed through browser printing. The browser printing method can be compatible with different browsers and various printers, which improves the flexibility of printer customization, and can Reduce dependence on hardware devices.

Specifically, when printing the text content retained in the text printing area based on the print function, the text content retained in the text printing area can be paginated based on the paging algorithm, to obtain at least two pages of content to be printed; then, through the browser object model, respectively perform printing processing for at least two pages of the content to be printed, and obtain the corresponding business receipt

Exemplarily, since the paging algorithm configured when the printing function is configured will indicate the number of printed lines on a single page, when paging processing is performed on the text content retained in the text printing area based on the paging algorithm, the number of printed lines on a single page can be paired based on the paging algorithm. The text content is processed by paging. For example, if the single-page printing function indicated by the paging algorithm is 10 lines, and the text content retained in the text printing area includes 23 lines of content, the first line to the tenth line can be used as the required printing. The content of the first page, the eleventh line to the twentieth line is the content of the second page to be printed, and the twenty-first to the twenty-third line is the content of the third page to be printed. In this way, through the above-mentioned paging processing, it is ensured that the printed content meets the printing requirements of the business receipt.

Furthermore, through the configured browser object model, the printing component can be rendered, the page can be updated, and the printing function can be called to print the content to be printed on each page that is paginated, so as to print out the header area and footer area, which is in line with the business receipt printing.
