Print and Save

If I have 2 opened documents, I want to print and then save, but I found if I put aDoc.close(SaveOptions.no);, it will not print the second file, how can I make it to print one document and close that document and then print second document ......

myTest();

alert("Finished");

function myTest(){

    for (i=0; i<app.documents.length; i++) {

  var aDoc = app.documents;

        if (aDoc.printPreferences.pageRange != ""){

            alert("a");

            aDoc.print(true);

         //   aDoc.close(SaveOptions.no);

                  }

      }

  }
