WPF打印问题

当我选择Microsoft XPS文档写入打印机，我的输出是完美的，但是当我选择我的HP 1020打印机机，打印机输出空白副本...以下是代码....WPF打印问题

private void printButton_Click(object sender, RoutedEventArgs e) 
    { 
     PrintInvoice pi = new PrintInvoice(); 
     pi.DataContext = this.DataContext; 
     PrintDialog printDlg = new System.Windows.Controls.PrintDialog(); 
     if (printDlg.ShowDialog() == true) 
     { 
      pi.Margin = new Thickness(30); 

      //now print the visual to printer to fit on the one page. 
      printDlg.PrintVisual(pi, "First Fit to Page WPF Print"); 
     } 
    }

的伎俩，你试过简化PrintInvoice，看看他们是被导致与惠普打印机问题的任何元素？ – RQDQ 2011-01-25 14:17:00

PrintInvoice是一个页面，它在Microsoft XPS Document Writer中的输出是完美的。 – 2011-01-25 14:28:49

这可能是由许多不同的事情造成的。有迹象表明，你可以添加，当正确执行，可能cause the flying men to return with goods and knowledge.

首先，你应该扩展到打印页面几步（代码a2zdotnet）：

System.Printing.PrintCapabilities capabilities = 
    printDlg.PrintQueue.GetPrintCapabilities(printDlg.PrintTicket); 

//get scale of the print wrt to screen of WPF visual 
double scale = Math.Min(capabilities.PageImageableArea.ExtentWidth/this.ActualWidth, capabilities.PageImageableArea.ExtentHeight/
       this.ActualHeight); 

//Transform the Visual to scale 
this.LayoutTransform = new ScaleTransform(scale, scale); 

//get the size of the printer page 
Size sz = new Size(capabilities.PageImageableArea.ExtentWidth, capabilities.PageImageableArea.ExtentHeight); 

//update the layout of the visual to the printer page size. 
this.Measure(sz); 
this.Arrange(new Rect(new Point(capabilities.PageImageableArea.OriginWidth, capabilities.PageImageableArea.OriginHeight), sz)); 

    //now print the visual to printer to fit on the one page. 
    printDlg.PrintVisual(this, "Code ganked from http://www.a2zdotnet.com/View.aspx?id=66");

货物邪教代码是度量和安排步骤。通常，如果您打电话给Measure并通过new Size(Double.MaxValue, Double.MaxValue)这就是您所需要做的。

第二种仪式涉及碰撞分派器。

visual.DataContext = foo; 
Dispatcher.Invoke((Action)()=>{;}); // bamp 
// print here

试试看看是否有帮助。

这XAML确实在某些情况下

<ScrollViewer HorizontalScrollBarVisibility="Hidden" VerticalScrollBarVisibility="Hidden"> 
    <... Name="myPrintElement" /> 
</ScrollViewer >
