            if (ph.IsPrintingAvailable)
            {
                ph.PageSettings = set_print_page;

                PrintableComponentLink link = new PrintableComponentLink(ps);
                link.Component = gc;
                link.Landscape = true;
                PageHeaderFooter phf = link.PageHeaderFooter as PageHeaderFooter;
                phf.Header.Content.Clear();
                phf.Header.Content.AddRange(new string[] { "", drv["线路名"].ToString() + "站点信息表", "" });
                phf.Header.Font = new System.Drawing.Font("宋体", 16, System.Drawing.FontStyle.Regular);
                phf.Header.LineAlignment = BrickAlignment.Center;
                phf.Footer.Content.Clear();
                phf.Footer.Content.AddRange(new string[] { "", String.Format("打印时间: {0:g}", DateTime.Now), "" });
