Hi Roh,
The RadPrintDocument can only be used with RadControls implementing the IPrintable interface. This is also the type of the AssociatedObject property. If you want to use it with a standard picture box, you will need to inherit it and implement the interface similarly as demonstrated here: https://docs.telerik.com/devtools/winforms/telerik-presentation-framework/printing-support/how-to/create-prinatble-panel.
Please also check my code snippet below:
I hope this will help.
