我在POS网站工作,当我打印销售数据收据时,我想用id在div末尾停止打印机,但没有发生,打印机继续打印。我使用了css属性“page break after:always”,但它不起作用。我的css类看起来像

    @media print {
     .paper-size {
       float: none !important;
       display: block !important;
       width: 76mm !important;
       page-break-after: always !important;
    }}
这是我的HTML部分

所以我想做的是,当打印机打印最后一个div时,带有“发票号”和“患者姓名”的打印机应该在该点停止,但不会发生。打印完有用的数据后,打印机打印出空白页,所以我通过关闭它来停止打印

和javascript部分

   static print(content:any) {
    let head:any = document.getElementsByTagName('head')[0];
    let htmlContent = '<html><head>'+head.innerHTML+'</head><body onload="window.print();window.close()">'+content.innerHTML+'</body></html>';

    let popupWin = window.open('', '_blank', 'top=0,left=0,height=100%,width=auto');
    popupWin.document.open();
    popupWin.document.write(htmlContent);
    popupWin.document.close();
}
静态打印(内容:任意){
让head:any=document.getElementsByTagName('head')[0];
让htmlContent=''+head.innerHTML+''+content.innerHTML+'';
让popupWin=window.open(“”,"u blank’,“top=0,left=0,height=100%,width=auto”);
popupWin.document.open();
popupWin.document.write(htmlContent);
popupWin.document.close();
}
