We recently added a sample on using ScriptX within a console application to print html content downloaded from arbitrary urls. The sample contains some interesting utility code of using callbacks from the PrintHtmlEx() method and also code for wrapping the use of Security Manager and ScriptX. Although a little overkill in a console application these wrappers are useful in services.
We are continuing to work on improving our documentation on using ScriptX in services/applications and also to provide more sample code.
