我在Asp.net上做报告。当我打印报告时，背景颜色没有出现在firefox中的打印预览中。我想在Printer中打印背景颜色。请指导我的工作。我的代码如下。我想用编程来做这件事。
在页面设置中不启用背景颜色和图像

或有没有办法通过编程启用

我认为它是一个浏览器设置。您无法在CSS中执行任何操作。在Windows中 - File > Page Setup... > Print Background.
答案 1 :(得分：0)
Css Webkit Property Works正常"-webkit-print-color-adjust: exact;"
@media print {
element {
background-color: #1a4567 !important;
-webkit-print-color-adjust: exact;
}}
@media print {
.vendorListHeading th {
color: white !important;
}}
希望这个帮助!!

点击打印设置（Chrome）点击背景颜色并打印它肯定会有效。
