您几乎无法控制浏览器的打印方法.您最多可以建议，但是如果浏览器的打印设置有不打印背景图像"，那么您必须重写页面以将背景图像变成恰好位于其他内容后面的浮动前景"图像.

You have very little control over a browser's printing methods. At most you can SUGGEST, but if the browser's print settings have "don't print background images", there's nothing you can do without rewriting your page to turn the background images into floating "foreground" images that happen to be behind other content.
