let printData = document.getElementById("printDiv").innerHTML; //获得 div 里的所有 html 数据
window.document.body.innerHTML = printData; //把 html 里的数据 复制给 body 的 html 数据 ,相当于重置了 整个页面的 内容
window.print(); // 开始打印
let newWin=window.open('http://www.google.com', '', '');
let printData=document.getElementById("printDiv").innerHTML;
newWin.document.write(printData);
newWin.document.location.reload();
newWin.print();
链接: 【Vue】vue使用Print.js 打印选中区域的html.
补充(未测试):vue3+vite+print-js打印页面指定元素踩坑:宽度超过默认宽度导致打印不全、字体大小失效、自定义字体失效.
链接: vue中使用文件打印.
新建文件:print.js

使用:
<div ref="paper">
<div>
<p>这是一个封面</p>
</div>
<p style="page-break-after: always"></p><!-- 设置在这里分页 -->
<div>
<p>这是内容第一页</p>
</div>
</div>
import { Print } from '@/utils/Print.js';
const paper = ref();
function exportPDF() {
nextTick(() => {
Print(paper.value);
});
}
