Best way to print using wpf 4

Howdy, I need to be able to print wpf from my application. I'm just trying to print a transaction receipt.

I found that using

PrintDialog pDialog = new PrintDialog();

pDialog.PrintVisual (new receipt ("transaction name", "my store"), "documentTitle");

Does the trick differ. "Receipt () is a user control that displays transaction details.

How are you going to do this? Is this the right way? What should I do if I do not know the printer to be used? should I make usercontrol only as wide as a printer with a thermal printer?

Any suggestions would be great!

This is what I do to print a WPF control:

 System.Windows.Controls.PrintDialog printDlg = new System.Windows.Controls.PrintDialog(); if (printDlg.ShowDialog() == true) { System.Printing.PrintCapabilities capabilities = printDlg.PrintQueue.GetPrintCapabilities(printDlg.PrintTicket); double scale = Math.Min( capabilities.PageImageableArea.ExtentWidth / control.ActualWidth, capabilities.PageImageableArea.ExtentHeight / control.ActualHeight); control.LayoutTransform = new System.Windows.Media.ScaleTransform(scale, scale); Size sz = new Size(capabilities.PageImageableArea.ExtentWidth, capabilities.PageImageableArea.ExtentHeight); control.Measure(sz); control.Arrange(new Rect(new Point(capabilities.PageImageableArea.OriginWidth, capabilities.PageImageableArea.OriginHeight), sz)); printDlg.PrintVisual(control, "My App"); }

This seems to work well.

If you do not know the printer to be used and want to ask the user, does this mean that you want to show the print dialog? What about:

 pDialog.ShowDialog();
