1、WPF 打印操做之PrintDocument，WPF获取打印机列表，WPF指定打印机html
PrintDocumentapi
定义一个可重用的对象，当从Windows Forms应用程序进行打印时，该对象将输出发送到打印机this
一般，您将建立PrintDocument类的实例，设置诸如DocumentName和PrinterSettings之类的属性，而后调用Print方法来启动打印过程。经过使用PrintPageEventArgs的Graphics Graphics属性，在您指定要打印输出的地方处理PrintPage事件。url

2、wpf获取系统可用打印机列表code
//获取打印机列表 StringCollection strList = PrinterSettings.InstalledPrinters;
使用打印机名称，指定特定的打印机进行打印。orm
PrintDocument pd = new PrintDocument(); pd.PrinterSettings.PrinterName = "Canon TS3100 series (副本 1)";
3、打印示例htm
Font printFont = null; StreamReader streamToPrint = null; private void Button_Click_1(object sender, RoutedEventArgs e) { try { streamToPrint = new StreamReader ("G:\\桌面\\新建文本文档.txt"); try { printFont = new Font("Arial", 10); PrintDocument pd = new PrintDocument(); pd.PrinterSettings.PrinterName = "Canon TS3100 series (副本 1)"; pd.PrintPage += new PrintPageEventHandler (this.pd_PrintPage); pd.Print(); } finally { streamToPrint.Close(); } } catch (Exception ex) { MessageBox.Show(ex.Message); } } // The PrintPage event is raised for each page to be printed. private void pd_PrintPage(object sender, PrintPageEventArgs ev) { float linesPerPage = 0; float yPos = 0; int count = 0; float leftMargin = ev.MarginBounds.Left; float topMargin = ev.MarginBounds.Top; string line = null; // Calculate the number of lines per page. linesPerPage = ev.MarginBounds.Height / printFont.GetHeight(ev.Graphics); // Print each line of the file. while (count < linesPerPage && ((line = streamToPrint.ReadLine()) != null)) { yPos = topMargin + (count * printFont.GetHeight(ev.Graphics)); ev.Graphics.DrawString(line, printFont, System.Drawing.Brushes.Black, leftMargin, yPos, new StringFormat()); count++; } // If more lines exist, print another page. if (line != null) ev.HasMorePages = true; else ev.HasMorePages = false; }
