ImageGear .NET v25.1 - Updated
Printing in WPF Environment
User Guide > How to Work with... > Common Operations > Printing > Printing in WPF Environment

ImageGear displays or prints an image in an ImGearPageView Class control, or in a System.Windows.Controls.Canvas element. In either case, you have a System.Windows.Media.Visual object that you can send to a printer or write into an XpsDocumentWriter. You can also put it into another Visual object, into a FixedDocument or FlowDocument and then print the parent object.

It is important to understand Specifying Scale Settings in ImageGear for displaying and printing images.
