Question

c# 打印panel内容模糊怎么办？代码如下：

//打印每页的panel
public void SettingReportPage(Control con, Graphics g, int y)
{
Bitmap bp = new Bitmap(con.Width, con.Height );
bp.SetResolution(3000, 3000); //分辨率

g.InterpolationMode = InterpolationMode.HighQualityBicubic;
g.SmoothingMode = SmoothingMode.HighQuality;
g.PixelOffsetMode = PixelOffsetMode.Half;
g.CompositingQuality = CompositingQuality.HighQuality;
g.TextRenderingHint = TextRenderingHint.ClearTypeGridFit;

Rectangle rect1;
rect1 = new Rectangle(0, 0, bp.Width, bp.Height);
con.DrawToBitmap(bp, rect1);
g.DrawImage(bp, (int)con.Location.X+9, y, bp.Width, bp.Height);
}

1.新建窗口Form1，在桐腔上面拖1个Panel，1个Button，1个printDocument，1个printDocument1
2.在Form1.cs中写入代码陪备：

private void printDocument1_PrintPage_1(object sender, PrintPageEventArgs e)
{
//局乱衫打印内容 为 局部的 this.panel1
Bitmap _NewBitmap = new Bitmap(panel.Width, panel.Height);
panel.DrawToBitmap(_NewBitmap, new Rectangle(0, 0
