在页面上加入代码可根据需求自己调整
<style media="printContent"> @page { size: auto; /* auto is the initial value / margin: 3mm; / this affects the margin in the printer settings */ } html { background-color: #ffffff; margin: 0px; /* this affects the margin on the html before sending to printer */ } body { border: solid 1px rgba(255,255,255,0); /* margin: 10mm 15mm 10mm 15mm; margin you want for the content */ } </style>
