WinForm打印html字符串

思路

使用WebBrowser加载html内容，输出成Image进行打印。

代码

var print = new PrintDocument();
print.DefaultPageSettings.Margins = new Margins(0, 0, 0, 0);
print.DefaultPageSettings.Landscape = landscape;
print.PrintPage += (o, e) =>
{
    var img = new Bitmap(e.PageBounds.Width, e.PageBounds.Height);
    var br = new WebBrowser();
    br.ScrollBarsEnabled = false;
    br.Width = e.PageBounds.Width;
    br.Height = e.PageBounds.Height;
    br.DocumentText = content;
    br.Document.Write(content);
    br.DrawToBitmap(img, e.PageBounds);
    e.Graphics.DrawImage(img, e.PageBounds);
};
print.Print();
