Part 2 of trying to print to postscript.

Current:

function mySnippet(){
    //<fragment>
    //Prints the active document using the specified printer preset.
    var myDocument = app.documents.item(0);
    myDocument.print(true, app.printerPresets.item("ps"));
	var printFile = "/Users/john/Desktop/PS_Hotfolder/In/" + myDocument.name;
	if(printFile.indexOf(".indd")!=-1){
		var myRegularExpression = /.indd/gi
		printFile = printFile.replace(myRegularExpression, ".ps");
	}
	//alert(printFile);

I have verified the preset is activated correctly. With the alert, it has returned the file name I am after.

Where I'm stuck: The next window where to save the postscript file fails for me. No postscript is created nor does it enter the name in the save dialogue for me.

Question: What is the code line to call upon the save dialogue so I may enter the save name?

Thanks in advance
