1，打印设置与管理。
1.1，引入程序集：
System.Printing.dll，ReachFramework.dll
1.2，主要管理类介绍：
LocalPrintServer：本地打印服务器（应用程序正在其上运行的计算机）用于对其所拥有的众多打印队列进行管理。
PrintQueue：打印队列，封装了打印机管理及作业等功能。可以通过此获取封装的打印机名，打印机端口，打印机状态等信息，以及对打印机的控制（例如打印作业,中止打印作业，取消打印作业）。总之一个PrintQueue控制一个打印机。
PrintTicket:：页面打印效果设置，例如纵向，横向打印，双面打印，打印份数，纸张大小 等。
PrintSystemJobInfo：详细定义的打印作业，包含打印作业的文档名，作业名，状态，所有者，页数，大小，提交时间（格林时间）。
1.3，应用：
获取默认的打印队列（即默认的打印机）。
PrintQueue defaultPrintQueue = LocalPrintServer.GetDefaultPrintQueue()获取所有的打印队列。
LocalPrintServer printServer = new LocalPrintServer();
PrintQueueCollection queues= printServer.GetPrintQueues()；获取打印队列支持的所有纸张类型与大小。
queue.GetPrintCapabilities().PageMediaSizeCapability；对打印队列进行继续，暂停，取消操作。
private void queueStack_Click(object sender, RoutedEventArgs e)
{
if(e.Source is Button && queuesList.SelectedItem!=null)
{
Button btn = e.Source as Button;
PrintQueue queueTemp = queuesList.SelectedItem as PrintQueue;
// PrintQueue queue= printServer.GetPrintQueue(queueTemp.FullName);
//需要使用PrintQueue构造函数指明权限，否则报拒绝访问异常
PrintQueue queue = new PrintQueue(printServer, queueTemp.FullName,PrintSystemDesiredAccess.AdministratePrinter);
switch (btn.Content.ToString())
{
case "Pause Queue":
queue.Pause();
break;
case "Resume Queue":
queue.Resume();
break;
case "Purge Queue":
//移除所有作业
queue.Purge();
break;
case "Refresh Queue":
queue.Refresh();
break;
case "SettingDefaultPrinter":
string printerName = queue.FullName;
SetDefaultPrinter(printerName);
break;
default:
break;
}
GetPrintQueues();
}
}
获取打印队列的所有作业列表。
//如果抛出NullReferenceException ，就如下通过name重新获取队列后再获取作业列表
server.GetPrintQueue(name).GetPrintJobInfoCollection()对作业进行暂停，继续，取消，刷新等操作。
private void jobStack_Click(object sender, RoutedEventArgs e)
{
if (e.Source is Button && jobList.SelectedItem != null)
{
Button btn = e.Source as Button;
PrintSystemJobInfo jobInfo = jobList.SelectedItem as PrintSystemJobInfo;
switch (btn.Content.ToString())
{
case "Pause Job":
jobInfo.Pause();
break;
case "Resume Job":
jobInfo.Resume();
break;
case "Purge Job":
//移除所有作业
jobInfo.Cancel();
break;
case "Refresh Job":
jobInfo.Refresh();
break;
default:
break;
}
}
}设置默认打印机。
/// <summary>
/// 设置默认打印机

/// <returns>true为成功，false为失败</returns>
[DllImport("winspool.drv")]
public static extern bool SetDefaultPrinter(String Name); //调用win api将指定名称的打印机设置为默认打印机1.4，效果。
1.5，Demo链接。
https://download.csdn.net/download/lingxiao16888/89327105?spm=1001.2014.3001.5503
2，打印。
2.1，主要参与打印的类与属性
PrintDialog类：可进行打印作业的封装类。
PrintDialog.PrintQueue：完成本次打印作业的打印机（默认为PC的默认打印机）。
PrintDialog.PrintTicket：完成此次打印作业的纸张大小，打印方向等（默认为PC的默认打印机中的默认打印作业配置）信息。
PrintDialog.PrintableAreaWidth:打印区域的宽度，来源于PrintDialog.PrintTicket.PageMediaSize.Width。
PrintDialog.PrintableAreaHeight:打印区域的高度，来源于PrintDialog.PrintTicket.PageMediaSize.Height。
DocumentPaginator：文档分页器，将内容分割到多页，每页由一个DocumentPage对象表示。DocumentPage实际上是一个封装器，封装Visual对象并添加了一些辅助对象。DocumentPage只增加来了三个属性：Size：页面大小，ContentBox：添加外边距之后内容区域的尺寸，BleedBox：用于显示打印产品相关信息，公司等在纸张上并在页面边界之外。
XpsDocument:用于保存 XPS 文档内容的 System.IO.Packaging.Package。
XpsDocumentWriter:提供用于写入 XPS 文档或打印队列的方法,PrintDialog的打印工作便是通过封装了PrintQueue的XpsDocumentWriter类完成。
2.2，打印可视元素。
<Canvas Background="AliceBlue" x:Name="canvas01">
<Path Panel.ZIndex="1" Stroke="Red" StrokeThickness="2" Fill="SkyBlue" Grid.RowSpan="2" Grid.ColumnSpan="2">
<Path.Data>

<CombinedGeometry.Geometry2>
<EllipseGeometry Center="110,70" RadiusX="50" RadiusY="40"></EllipseGeometry>
</CombinedGeometry.Geometry2>
</CombinedGeometry>
</Path.Data>
</Path>
<TextBlock Panel.ZIndex="0" FontSize="22" FontWeight="Bold" Canvas.Top="50">春风不度玉门关</TextBlock>
</Canvas> private void btnPrint_Click(object sender, RoutedEventArgs e)
{
PrintDialog pd = new PrintDialog();
pd.CurrentPageEnabled = true;
pd.SelectedPagesEnabled = true;
pd.UserPageRangeEnabled = true;
if ( pd.ShowDialog()== true)
{
//PrintableAreaWidth,PrintableAreaHeight大小由PrintDialog.PrintTicket提供
//重新布局Grid大小为PrintableAreaWidth,PrintableAreaHeight,其实在这里就是重新设置Canvas的大小
canvas01.Measure(new Size(pd.PrintableAreaWidth, pd.PrintableAreaHeight));
canvas01.Arrange(new Rect(0, 0, pd.PrintableAreaWidth, pd.PrintableAreaHeight));
pd.PrintVisual(canvas01, "可是元素打印");
}
}注明：PrintDialog. PrintVisual()只考虑指定的元素和其子元素，而不考虑其父元素的细节，所以可以对指定元素的父元素采取隐藏的操作，而不影响打印效果。
效果：
2.2，打印文档。

荷塘月色
<Run FontSize="12" FontWeight="Normal" xml:space="preserve"> 朱自清</Run>
</Paragraph>
<Paragraph TextIndent="32">
这几天心里颇不宁静。今晚在院子里坐着乘凉，忽然想起日日走过的荷塘，在这满月的光里，总该另有一番样子吧。月亮渐渐地升高了，墙外马路上孩子们的欢笑，已经听不见了；妻在屋里拍着闰儿⑴，迷迷糊糊地哼着眠歌。我悄悄地披了大衫，带上门出去。
</Paragraph>
<Paragraph>
沿着荷塘，是一条曲折的小煤屑路。这是一条幽僻的路；白天也少人走，夜晚更加寂寞。荷塘四面，长着许多树，蓊蓊郁郁⑵的。路的一旁，是些杨柳，和一些不知道名字的树。没有月光的晚上，这路上阴森森的，有些怕人。今晚却很好，虽然月光也还是淡淡的。
</Paragraph>
<Paragraph>
路上只我一个人，背着手踱⑶着。这一片天地好像是我的；我也像超出了平常的自己，到了另一个世界里。我爱热闹，也爱冷静；爱群居，也爱独处。像今晚上，一个人在这苍茫的月下，什么都可以想，什么都可以不想，便觉是个自由的人。白天里一定要做的事，一定要说的话，现在都可不理。这是独处的妙处，我且受用这无边的荷香月色好了。
</Paragraph>
<Paragraph>
曲曲折折的荷塘上面，弥望⑷的是田田⑸的叶子。叶子出水很高，像亭亭的舞女的裙。层层的叶子中间，零星地点缀着些白花，有袅娜⑹地开着的，有羞涩地打着朵儿的；正如一粒粒的明珠，又如碧天里的星星，又如刚出浴的美人。微风过处，送来缕缕清香，仿佛远处高楼上渺茫的歌声似的。这时候叶子与花也有一丝的颤动，像闪电般，霎时传过荷塘的那边去了。叶子本是肩并肩密密地挨着，这便宛然有了一道凝碧的波痕。叶子底下是脉脉⑺的流水，遮住了，不能见一些颜色；而叶子却更见风致⑻了。
</Paragraph>
<Paragraph>
月光如流水一般，静静地泻在这一片叶子和花上。薄薄的青雾浮起在荷塘里。叶子和花仿佛在牛乳中洗过一样；又像笼着轻纱的梦。虽然是满月，天上却有一层淡淡的云，所以不能朗照；但我以为这恰是到了好处——酣眠固不可少，小睡也别有风味的。月光是隔了树照过来的，高处丛生的灌木，落下参差的斑驳的黑影，峭楞楞如鬼一般；弯弯的杨柳的稀疏的倩影，却又像是画在荷叶上。塘中的月色并不均匀；但光与影有着和谐的旋律，如梵婀玲⑼上奏着的名曲。
</Paragraph>
<Paragraph>
荷塘的四面，远远近近，高高低低都是树，而杨柳最多。这些树将一片荷塘重重围住；只在小路一旁，漏着几段空隙，像是特为月光留下的。树色一例是阴阴的，乍看像一团烟雾；但杨柳的丰姿⑽，便在烟雾里也辨得出。树梢上隐隐约约的是一带远山，只有些大意罢了。树缝里也漏着一两点路灯光，没精打采的，是渴睡⑾人的眼。这时候最热闹的，要数树上的蝉声与水里的蛙声；但热闹是它们的，我什么也没有。
</Paragraph>
<Paragraph>
忽然想起采莲的事情来了。采莲是江南的旧俗，似乎很早就有，而六朝时为盛；从诗歌里可以约略知道。采莲的是少年的女子，她们是荡着小船，唱着艳歌去的。采莲人不用说很多，还有看采莲的人。那是一个热闹的季节，也是一个风流的季节。梁元帝《采莲赋》里说得好：
</Paragraph>
<Paragraph>
于是妖童媛女⑿，荡舟心许；鷁首⒀徐回，兼传羽杯⒁；棹⒂将移而藻挂，船欲动而萍开。尔其纤腰束素⒃，迁延顾步⒄；夏始春余，叶嫩花初，恐沾裳而浅笑，畏倾船而敛裾⒅。
</Paragraph>
<Paragraph>
可见当时嬉游的光景了。这真是有趣的事，可惜我们现在早已无福消受了。
</Paragraph>
<Paragraph>
于是又记起，《西洲曲》里的句子：
</Paragraph>
<Paragraph>
采莲南塘秋，莲花过人头；低头弄莲子，莲子清如水。
</Paragraph>
<Paragraph>
今晚若有采莲人，这儿的莲花也算得“过人头”了；只不见一些流水的影子，是不行的。这令我到底惦着江南了。——这样想着，猛一抬头，不觉已是自己的门前；轻轻地推门进去，什么声息也没有，妻已睡熟好久了。
</Paragraph>

2.5，打印到文件。
使用XPSDocumentWrite将内容打印到Xps文件。
private void btnPrintFile_Click(object sender, RoutedEventArgs e)
{
SaveFileDialog sfd = new SaveFileDialog();
sfd.Filter = "xps文件|*.xps";
if (sfd.ShowDialog() == true)
{
FlowDocument fd = fsv01.Document;
fd.ColumnWidth = LocalPrintServer.GetDefaultPrintQueue().DefaultPrintTicket.PageMediaSize.Width.Value;
XpsDocument document = new XpsDocument(sfd.FileName, System.IO.FileAccess.ReadWrite);
XpsDocumentWriter writer = XpsDocument.CreateXpsDocumentWriter(document);
writer.Write((fd as IDocumentPaginatorSource).DocumentPaginator);
document.Close();
}
}2.6，使用XpsDocumentWrite打印。
private void btnPrint2_Click(object sender, RoutedEventArgs e)
{
FlowDocument fd = fsv01.Document;
fd.ColumnWidth = LocalPrintServer.GetDefaultPrintQueue().DefaultPrintTicket.PageMediaSize.Width.Value;
//从打印队列上获取xpsDocumentWriter
XpsDocumentWriter writer = PrintQueue.CreateXpsDocumentWriter(LocalPrintServer.GetDefaultPrintQueue());
writer.WritingCompleted += Writer_WritingCompleted;
writer.WriteAsync((fd as IDocumentPaginatorSource).DocumentPaginator);
}
private void Writer_WritingCompleted(object sender, System.Windows.Documents.Serialization.WritingCompletedEventArgs e)
{
MessageBox.Show("保存完成");
}事实上PrintDialog的打印工作也是委托给XpsDocumentWrite完成。
3，打印预览。
使用固定文档容器（DocumentViewer）展现文档预览效果。
<Window x:Class="文档打印.PreView"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:文档打印"
mc:Ignorable="d"
Title="PreView" Height="500" Width="500" WindowState="Maximized">
<Grid>
<DocumentViewer x:Name="viewer"></DocumentViewer>
</Grid>
</Window> private void btnPrePrint_Click(object sender, RoutedEventArgs e)
{
if (System.IO.Directory.Exists("temp"))
{
if(System.IO.Directory.GetFileSystemEntries("temp").Length > 0)
{
System.IO.Directory.Delete("temp", true);
}
}
if (!System.IO.Directory.Exists("temp"))
{
System.IO.Directory.CreateDirectory("temp");
}
string tempFilePath = string.Format("temp/{0}.xps", Guid.NewGuid());
XpsDocument document = new XpsDocument(tempFilePath, System.IO.FileAccess.ReadWrite);
XpsDocumentWriter writer = XpsDocument.CreateXpsDocumentWriter(document);
FlowDocument fd = fsv01.Document;
fsv01.Document = null;
fd.ColumnWidth = LocalPrintServer.GetDefaultPrintQueue().DefaultPrintTicket.PageMediaSize.Width.Value;
DocumentPaginator paginator = (fd as IDocumentPaginatorSource).DocumentPaginator;
writer.WritingCompleted += Writer_WritingCompleted;
writer.Write(paginator);
PreView win = new PreView(document.GetFixedDocumentSequence());
win.ShowDialog();
document.Close();
fsv01.Document = fd;
//删除临时文档
System.IO.File.Delete(tempFilePath);
}注明： DocumentViewer.Document:类型为IDocumentPaginatorSource，虽然FlowDocument实现IDocumentPaginatorSource，但是DocumentViewer 仅支持 FixedDocument 或 FixedDocumentSequence 文档，所以这里必须通过XpsDocument将流文档转为固定文档。
效果：
