新建一个wpf应用程序，Xaml如下：
<Window x:Class="CreateBarCodeDemo.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid>
<StackPanel>
<Button Height="40" Width="80" Margin="20" Content="打印" Click="btnPrint_Click"/>
</StackPanel>
</Grid>
</Window>

项目引用BarcodeLib.dll(用来生成条码)。
两个窗体界面效果如下：
主窗体：
打印窗体：
主窗体的后置代码如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes; namespace CreateBarCodeDemo
{
/// <summary>
/// MainWindow.xaml 的交互逻辑
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
} private void btnPrint_Click(object sender, RoutedEventArgs e)
{
PrintWindow pw = new PrintWindow("路飞", "男", , "海贼", "橡胶果实", "船长", "500000000$");
pw.ShowDialog();
}
}
}
点击打印时，ShoW出打印窗体；
通过打印窗体的构造函数，传入要打印的信息；
打印窗体呈现完后，执行了Window_ContentRendered事件，进行打印标签；
打印方法里通过调用BarcodeLib.Barcode生成一个条码；
最后将整个打印窗体的布局打印出来。
打印窗体的后置代码如下：
using System;

private void CreateBarCode(string barCode)
{

string data = barCode;
if (data != null)

using (BarcodeLib.Barcode b = new BarcodeLib.Barcode())
{

} var stream = new MemoryStream();
image.Save(stream, System.Drawing.Imaging.ImageFormat.Png); stream.Seek(, SeekOrigin.Begin);
var bi = new System.Windows.Media.Imaging.BitmapImage();
bi.BeginInit();
bi.StreamSource = stream;
bi.EndInit(); imageSource = bi;
}
catch { }
}
this.Imageid.Source = imageSource;
} /// <summary>

private void Window_ContentRendered(object sender, EventArgs e)

//if (dialog.ShowDialog() == true)
{

using (DrawingContext dc = visual.RenderOpen())
{

dialog.PrintableAreaWidth * 0.90,
dialog.PrintableAreaHeight * 0.90);
dc.DrawRectangle(new VisualBrush(printArea), null, rect);
} dialog.PrintVisual(visual, null);
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
MessageBox.Show(ex.StackTrace);
}
this.Close();
}
}
}
打印的标签图片如下：
