}
为什么上面和程序什么也打印不出来，
预览时，有两页，单击预览对话框左上角的打印，只打印一张空白纸出来，明明预览看到有内容啊，这是什么么？
帮帮我修改一下，可以多给分哈

public void Print()
        {
            this.printdoc = new System.Drawing.Printing.PrintDocument();
            this.printdoc.PrintPage += new System.Drawing.Printing.PrintPageEventHandler(printdoc_PrintPage);
            this.printdoc.Print();
        }
private void printdoc_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
  printFont = new Font("Trebuchet MS", 7);
                string date =datetime.now.ToString("yyMM");
                DrawString(e, date, GetPoint(0.55m + (0.8m - frm.GetFontWidth(printFont, date)) / 2 - decX, d - decY));

}
 private void DrawString(System.Drawing.Printing.PrintPageEventArgs e, string s, Point point)
        {
            e.Graphics.DrawString(s, printFont, brush, GetRect(point));
        }

这个是没有打印预览窗体的打印,你试试

楼主这样写法有点不对劲
建议将 PrintDocument、PrintDialog等打印对象的初始化放到构造函数中去。
