Problema al imprimir desde Java

http://java.sun.com/j2se/1.4.2/docs/...ntService.html

Código:

DocFlavor flavor = DocFlavor.INPUT_STREAM.POSTSCRIPT;
   PrintRequestAttributeSet aset = new HashPrintRequestHashAttributeSet();
   aset.add(MediaSizeName.ISO_A4);   
PrintService[] pservices =
                 PrintServiceLookup.lookupPrintServices(flavor, aset);
   if (pservices.length > 0) {
       DocPrintJob pj = pservices[0].createPrintJob();
       // InputStreamDoc is an implementation of the Doc interface //
       Doc doc = new InputStreamDoc("test.ps", flavor);
       try {
             pj.print(doc, aset);
        } catch (PrintException e) { 
        }
   }

La tercera linea parece que pone tamaño A4.
