How to hide specific layer set using javascript, if even exist on PSD? I need to hide the group called Print preview, but is not always on PSD.

Try this: 

// 2022, use it at your own risk;
if (app.documents.length > 0) {
var thisName = "Print preview";
var theLayers = collectLayersByName(thisName);
for (var x = 0; x < theLayers.length; x++) {
    var idhide = stringIDToTypeID( "hide" );
    var desc22 = new ActionDescriptor();
    var list2 = new ActionList();
    var ref8 = new ActionReference();
    ref8.putIdentifier( stringIDToTypeID( "layer" ), theLayers[x][2] );
    list2.putReference( ref8 );
    desc22.putList( stringIDToTypeID( "null" ), list2 );
    executeAction( idhide, desc22, DialogModes.NO );
    }
};
////// collect layers with certain name //////
function collectLayersByName (aName) {
// get number of layers;
var ref = new ActionReference();
ref.putProperty(stringIDToTypeID('property'), stringIDToTypeID('numberOfLayers'));
ref.putEnumerated( charIDToTypeID("Dcmn"), charIDToTypeID("Ordn"), charIDToTypeID("Trgt") ); 
var applicationDesc = executeActionGet(ref);
var theNumber = applicationDesc.getInteger(stringIDToTypeID("numberOfLayers"));
// process the layers;
var theLayers = new Array;
for (var m = 0; m <= theNumber; m++) {
try {
var ref = new ActionReference();
ref.putIndex( charIDToTypeID( "Lyr " ), m);
var layerDesc = executeActionGet(ref);
var layerSet = typeIDToStringID(layerDesc.getEnumerationValue(stringIDToTypeID("layerSection")));
var isBackground = layerDesc.getBoolean(stringIDToTypeID("background"));
// if group collect values;
if (layerSet != "layerSectionEnd" /*&& layerSet != "layerSectionStart"*/ && isBackground != true) {
var theName = layerDesc.getString(stringIDToTypeID('name'));
var theID = layerDesc.getInteger(stringIDToTypeID('layerID'));
var theIndex = layerDesc.getInteger(stringIDToTypeID('itemIndex'));
if (theName == aName) {theLayers.push([theName, theIndex, theID])}
};
}
catch (e) {};
};
return theLayers
};

Try this one, the normal limitations apply with getByName:

 

// Code modified from a script from Chuck Uebele

#target photoshop

toggleGroupVisibility("Print preview");

function toggleGroupVisibility(groupName) {
    if (documents.length > 0) {
        try {
            var toggleGroup = activeDocument.layerSets.getByName(groupName);
            toggleGroup.visible = toggleGroup.visible === false;
        } catch (e) { }
    }
}

 

 

Or to simply hide:

 

// Code modified from a script from Chuck Uebele

#target photoshop

hideGroupVisibility("Print preview");

function hideGroupVisibility(groupName) {
    if (documents.length > 0) {
        try {
            var hideGroup = activeDocument.layerSets.getByName(groupName);
            hideGroup.visible = false;
        } catch (e) { }
    }
}

    try{
(r = new ActionReference()).putName(stringIDToTypeID('layer'), 'Print preview');
(d = new ActionDescriptor()).putReference(stringIDToTypeID('target'), r);
executeAction(stringIDToTypeID('hide'), d, DialogModes.NO);} catch (e) {}

     

     

    * @c.pfaffenbichler's answer is more correct as code checks the layer type before hiding it

     

    Surprisingly, but this way also works:

     

    try{
(r = new ActionReference()).putName(stringIDToTypeID('layerSection'), 'Print preview');
(d = new ActionDescriptor()).putReference(stringIDToTypeID('target'), r);
executeAction(stringIDToTypeID('hide'), d, DialogModes.NO);} catch (e) {}

     

    (though on one condition - the document should not have another layer named "Print preview" or it can be, but located above the group)
