DevExpress 如何打印

 在打印按钮事件中添加以下代码

 

if (DevExpress.XtraPrinting.PrintHelper.IsPrintingAvailable)
            {
                PrintingSystem ps = new PrintingSystem();
                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[] { "", 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), "" });
                link.CreateDocument();
                link.ShowPreview();
            }
            else
            {
                XtraMessageBox.Show("打印机不可用...", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
            }
