Replace Seesion.Output by another console writer

[crumble]

Hello,
I'm executing a JScript in EA by using ScriptController from outside the application. Goal is to call a Enterprise Architect script from a C# application by previously getting the script directly from t_script database table and call it afterwards.
Usually the EA JScript user calls Session.Output to print logs to console. This can't be used from outside.
I tried to replace it by simply calling print instead, but this is not working. A COMException is called with "Object expected" as message.
Does anybody knows a way to redirect messages by replacing Session.Output by something else?
The change is done dynamically without modifying the original script content.
