TrappingType

Question

I am trying to put together a script for printing among other things. I was browsing Jongware's "Illustrator CS6 Object Reference.chm" in the printing section and I came across "TrappingType".
I'm jumping to conclusions here; if I print via javascript I can have it do the trapping for me (I am already aware of the pathfinder fly-out menu trapping)? I searched the forum for "TrappingType" and I found nothing. Am I drawing the wrong conclusion from this information? Does anyone have an example script using this feature?
=)

TrappingType is the returned value of the .trapping property, it doesn't say, but I assume it's read-only since it's in the "inkInfo" (info) object in the "Ink" object.
from the reference
// Displays the current documents inks in a text frame
var docRef = documents.add();
var textRef = docRef.textFrames.add();
// assemble a string of the inks in this document
var sInks = "";
var iLength = activeDocument.inkList.length;
for(var i=0; i<iLength; i++) {
    sInks += docRef.inkList[i].name;
    sInks += "\r\t";
    sInks += "TrapType = " + docRef.inkList[i].inkInfo.trapping; // TrapType = TrappingType.NORMALTRAPPING
    sInks += "\r\t";
    sInks += "Frequency = " + docRef.inkList[i].inkInfo.frequency;
    sInks += "\r\t";
    sInks += "Density = " + docRef.inkList[i].inkInfo.density;
    sInks += "\r";
textRef.contents = sInks;
textRef.top = 600;
textRef.left = 200;
redraw();
your options for setting Trapping
select your group
app.executeMenuCommand ('Live Pathfinder Trap'); // unfortunately, it brings up the Dialog
or, record an action setting trapping via PathFinder flyout menu, then play your action via javascript, this way the dialog won't show up, but it will use previously used settings.
