This time I will show you how to use JS to implement paging printing, and what are the precautions for using JS to implement paging printing. The following is a practical case, let’s take a look.

When calling

window.print(), the printing effect can be achieved, but when there is too much content, page printing is required.

There are several printing styles specified in the style

page-break-before and page-break-after CSS properties will not Modify the display of web pages on the screen. These two properties are used to control how the file is printed.

Each printing attribute can be set to 4 setting values: auto, always, left and right. Among them, Auto is the default value. Page breaks need to be set only when necessary.

If page-break-before is set to always, the printer will restart a new printing page when encountering a specific component.

If page-break-before is set to left, page break symbols will be inserted until the specified component appears on a left blank page.

If page-break-before is set to right, page break symbols will be inserted until the specified component appears on a blank page on the right.

The page-break-after attribute will add the page break symbol after the specified component, not before.

You will be able to see the setting of these properties in the following procedure,

<HTML>
　　<HEAD>
　　　　<TITLE>Listing 14-4</TITLE>
　　</HEAD>
　　<BODY>
　　　　<p>This is the first p.</p>
　　　　<p STYLE="page-break-before:always">This is the second p.</p>
