通過幾天的學習，終于對打印有了初步的認識，并實現了打印功能，下面將詳細介紹下如何使用DevExpress下的打印功能。

首先要實現打印功能必須添加一個引用：DevExpress.XtraPrint

實現打印需要用到的主要的類：

1. public class PrintingSystem : Component, ISupportInitialize,IPrintingSystem,IAccessible,IExporter,IPrintingSystemContext

該類負責提供生成報表的一些方法，還提供了對頁面進行設置和打印報表的一些函數，這個類的屬性包含了訪問其他管理報表的對象，如Document類、BrickGraphics類（在報表上進行畫圖的類）、XtraPageSettings類（提供對打印頁面進行設置的操作）

2. public class PrintableComponentLink : Link

該類的功能是對實現DevExpress.XtraPrinting.IPrintable接口的所有控件進行打印，它提供了一些基本的生成和打印報表的功能。在生成報表以后可以通過PrintingSystem將報表打印出來。

通過以上這兩個類就能完全實現各種控件的打印了，只要一個控件實現了DevExpress.XtraPrinting.IPrintable這個接口就能夠對該控件進行打印，如GridControl,CharControl等等，下面給出具體的實現方法：

public class PrintSettingController
{
PrintingSystem ps = null;
string formName = null;

        PrintableComponentLink link = null;

        string _PrintHeader = null;
/// <summary>
/// 打印時的標題
/// </summary>
public string PrintHeader
{
set
{
_PrintHeader = value;
}
}

        string _PrintFooter = null;
/// <summary>
/// 打印時頁腳
/// </summary>
public string PrintFooter
{
set
{
_PrintFooter = value;
}
}

        bool _landScape;
/// <summary>
/// 頁面橫縱向
/// </summary>
public bool LandScape
{
set { _landScape = value; }
}

        System.Drawing.Printing.PaperKind _paperKind;
/// <summary>
/// 紙型
/// </summary>
public System.Drawing.Printing.PaperKind PaperKind
{
set { _paperKind = value; }
}

        /// <summary>
/// 打印控制器
/// </summary>
/// <param name="control">要打印的部件</param>
public PrintSettingController(IPrintable control)
{
if (control == null) return;
Control c = (Control)control;
formName = c.FindForm().GetType().FullName + "." + c.Name;
ps = new DevExpress.XtraPrinting.PrintingSystem();
link = new DevExpress.XtraPrinting.PrintableComponentLink(ps);
ps.Links.Add(link);
link.Component = control;
}

        /// <summary>
/// 打印預覽
/// </summary>
public void Preview()
{
try
{
if (DevExpress.XtraPrinting.PrintHelper.IsPrintingAvailable)
{
Cursor.Current = Cursors.AppStarting;
if (_PrintHeader != null)
{
PageHeaderFooter phf = link.PageHeaderFooter as PageHeaderFooter;

                        //設置頁眉
phf.Header.Content.Clear();
phf.Header.Content.AddRange(new string[] { "", _PrintHeader, "" });
phf.Header.Font = new System.Drawing.Font("宋體", 14, System.Drawing.FontStyle.Bold);
phf.Header.LineAlignment = BrickAlignment.Center;

                        //設置頁腳
phf.Footer.Content.Clear();
phf.Footer.Content.AddRange(new string[] { "", "", _PrintFooter });
phf.Footer.Font = new System.Drawing.Font("宋體", 9, System.Drawing.FontStyle.Regular);
phf.Footer.LineAlignment = BrickAlignment.Center;

                    }
link.PaperKind = ps.PageSettings.PaperKind ;
link.Margins = ps.PageSettings.Margins;
link.Landscape = ps.PageSettings.Landscape;
link.CreateDocument();

//漢化
DevExpress.XtraPrinting.Localization.PreviewLocalizer.Active = new Dxperience.LocalizationCHS.DxperienceXtraPrintingLocalizationCHS();
ps.PreviewFormEx.Show();

                }
else
{
Cursor.Current = Cursors.Default;
MessageBox.Show("打印機不可用 ", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
}
finally
{
Cursor.Current = Cursors.Default;
}
}

        /// <summary>
/// 打印
/// </summary>
public void Print()
{
try
{
if (DevExpress.XtraPrinting.PrintHelper.IsPrintingAvailable)
{
if (_PrintHeader != null)
{
PageHeaderFooter phf = link.PageHeaderFooter as PageHeaderFooter;

                        //設置頁眉
phf.Header.Content.Clear();
phf.Header.Content.AddRange(new string[] { "", _PrintHeader, "" });
phf.Header.Font = new System.Drawing.Font("宋體", 14, System.Drawing.FontStyle.Bold);
phf.Header.LineAlignment = BrickAlignment.Center;

                        //設置頁腳
phf.Footer.Content.Clear();
phf.Footer.Content.AddRange(new string[] { "", "", _PrintFooter });
phf.Footer.Font = new System.Drawing.Font("宋體", 9, System.Drawing.FontStyle.Regular);
phf.Footer.LineAlignment = BrickAlignment.Center;

                    }
link.PaperKind = ps.PageSettings.PaperKind;
link.Margins = ps.PageSettings.Margins;
link.Landscape = ps.PageSettings.Landscape;
link.CreateDocument();
link.CreateDocument();
//漢化
DevExpress.XtraPrinting.Localization.PreviewLocalizer.Active = new Dxperience.LocalizationCHS.DxperienceXtraPrintingLocalizationCHS();
ps.Print();
}
else
{
Cursor.Current = Cursors.Default;
MessageBox.Show("打印機不可用 ", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
}
finally
{
}
}

        //獲取頁面設置信息
public void LoadPageSetting()
{

            System.Drawing.Printing.Margins margins = new System.Drawing.Printing.Margins(60, 60, 60, 60);
ps.PageSettings.Assign(margins, _paperKind, _landScape);

        }
}

客戶端如何使用：實例化PrintSettingController，進行參數設置，包括頁眉頁腳橫縱向紙型，當然所有這些設置信息也可以在PrintSettingControll類里進行設置了，我這里是需求的需要，所以加在了外面，PrintSystem.PageSettings屬性是XtraPageSettings類型，XtraPageSettings類封裝了所有的頁面設置信息，你可以在LoadPageSetting()函數里面進行修改，來實現自己想要的功能，例如可以把設置信息保存成XML文件

PrintSettingController psc = new PrintSettingController(this.gridControl1);
//頁眉
psc.PrintHeader = this.Text;

//頁腳
psc.PrintFooter = this.dateTimePicker1.Text.ToString();

//橫縱向
psc.LandScape = this.rbtnHorizon.Checked;

//紙型
psc.PaperKind = System.Drawing.Printing.PaperKind.A4;
//加載頁面設置信息
psc.LoadPageSetting();

psc.Preview();
