Script: print to PostScript

Hello


I need help to complete a script.
I must regularly convert. Have to. Ps
I would like to make a batch on a folder.

I tried recording an action script illustrator but always select the default print.

I find this script on the forum
But I still have the same problem it selects the default printer, how to force it to use the PostScript printer

Thank you

var docs = app.documents;

var docCount = docs.length;

// if there are opened documents, print them, otherwise ask for a folder to batch print

if (docCount>0) {

    alert(docCount);

    printOpenDocs(docs);

}

else {

var folder = Folder.selectDialog("Select Source Folder..."); // select folder

printFolder(folder);

}

// Prints and closes each open document

function printOpenDocs(docs) {

            for (j=docCount-1; j>=0; j--) {

                var jdoc = docs;

                jdoc.print(options);

                jdoc.close(SaveOptions.

            }
}

function printFolder(folder) {
    if (folder==null) {
            alert("Good Bye");
    }

    else {
        var files = folder.getFiles ("*.ai"); // get files
        var fileCount = files.length; // count them

        if (fileCount>0) {
            for (i=0; i<fileCount; i++) {
                var idoc = app.open(files);
                idoc.print();
                idoc.close();
            }
        }
        else {
            alert("There are no Illustrator files in this folder.");
        }
    }
}
