通过几天的学习,终于对打印有了初步的认识,并实现了打印功能,下面将详细介绍下如何使用DevExpress下的打印功能。

首先要实现打印功能必须添加一个引用:DevExpress.XtraPrint

实现打印需要用到的主要的类:

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

该类负责提供生成报表的一些方法,还提供了对页面进行设置和打印报表的一些函数,这个类的属性包含了访问其他管理报表的对象,如Document类、BrickGraphics类(在报表上进行画图的类)、XtraPageSettings类(提供对打印页面进行设置的操作)

2. public class PrintableComponentLink : Link

该类的功能是对实现DevExpress.XtraPrinting.IPrintable接口的所有控件进行打印,它提供了一些基本的生成和打印报表的功能。在生成报表以后可以通过PrintingSystem将报表打印出来。

通过以上这两个类就能完全实现各种控件的打印了,只要一个控件实现了DevExpress.XtraPrinting.IPrintable这个接口就能够对该控件进行打印,如GridControl,CharControl等等,下面给出具体的实现方法:

public class PrintSettingController
{
PrintingSystem ps = null;
string formName = null;
 
        PrintableComponentLink link = null;
 
        string _PrintHeader = null;
/// <summary>
/// 打印时的标题
/// </summary>
public string PrintHeader
{
set
{
_PrintHeader = value;
}
}
 
        string _PrintFooter = null;
/// <summary>
/// 打印时页脚
/// </summary>
public string PrintFooter
{
set
{
_PrintFooter = value;
}
}
 
        bool _landScape;
/// <summary>
/// 页面横纵向
/// </summary>
public bool LandScape
{
set { _landScape = value; }
}
 
        System.Drawing.Printing.PaperKind _paperKind;
/// <summary>
/// 纸型
/// </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 == nullreturn;
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>
/// 打印预览
/// </summary>
public void Preview()
{
try
{
if (DevExpress.XtraPrinting.PrintHelper.IsPrintingAvailable)
{
Cursor.Current = Cursors.AppStarting;
if (_PrintHeader != null)
{
PageHeaderFooter phf = link.PageHeaderFooter as PageHeaderFooter;
 
                        //设置页眉
phf.Header.Content.Clear();
phf.Header.Content.AddRange(new string[] { "", _PrintHeader, "" });
phf.Header.Font = new System.Drawing.Font("宋体", 14, System.Drawing.FontStyle.Bold);
phf.Header.LineAlignment = BrickAlignment.Center;
 
                        //设置页脚
phf.Footer.Content.Clear();
phf.Footer.Content.AddRange(new string[] { """", _PrintFooter });
phf.Footer.Font = new System.Drawing.Font("宋体", 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();
 
//汉化
DevExpress.XtraPrinting.Localization.PreviewLocalizer.Active = new Dxperience.LocalizationCHS.DxperienceXtraPrintingLocalizationCHS();
ps.PreviewFormEx.Show();
 
                }
else
{
Cursor.Current = Cursors.Default;
MessageBox.Show("打印机不可用 ""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;
 
                        //设置页眉
phf.Header.Content.Clear();
phf.Header.Content.AddRange(new string[] { "", _PrintHeader, "" });
phf.Header.Font = new System.Drawing.Font("宋体", 14, System.Drawing.FontStyle.Bold);
phf.Header.LineAlignment = BrickAlignment.Center;
 
                        //设置页脚
phf.Footer.Content.Clear();
phf.Footer.Content.AddRange(new string[] { """", _PrintFooter });
phf.Footer.Font = new System.Drawing.Font("宋体", 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();
//汉化
DevExpress.XtraPrinting.Localization.PreviewLocalizer.Active = new Dxperience.LocalizationCHS.DxperienceXtraPrintingLocalizationCHS();
ps.Print();
}
else
{
Cursor.Current = Cursors.Default;
MessageBox.Show("打印机不可用 ""提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
}
finally
{
}
}
 
        //获取页面设置信息
public void LoadPageSetting()
{
 
            System.Drawing.Printing.Margins margins = new System.Drawing.Printing.Margins(60, 60, 60, 60);
ps.PageSettings.Assign(margins, _paperKind, _landScape);
 
        }
}
客户端如何使用:实例化PrintSettingController,进行参数设置,包括页眉页脚横纵向纸型,当然所有这些设置信息也可以在PrintSettingControll类里进行设置了,我这里是需求的需要,所以加在了外面,PrintSystem.PageSettings属性是XtraPageSettings类型,XtraPageSettings类封装了所有的页面设置信息,你可以在LoadPageSetting()函数里面进行修改,来实现自己想要的功能,例如可以把设置信息保存成XML文件
PrintSettingController psc = new PrintSettingController(this.gridControl1);
//页眉
psc.PrintHeader = this.Text;
 
//页脚
psc.PrintFooter = this.dateTimePicker1.Text.ToString();
 
//横纵向
psc.LandScape = this.rbtnHorizon.Checked;
 
//纸型
psc.PaperKind = System.Drawing.Printing.PaperKind.A4;
//加载页面设置信息
psc.LoadPageSetting();
 
psc.Preview();
