Print job attributes are delivered to the print service via the print request attribute set supplied to DocPrintJob.print(). See e700 The Quintessential Printing Program Using a Printing Service to see how to set up a print job. 
    try {
        // Set up the attribute set
        PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
        if (portrait) {
            aset.add(OrientationRequested.PORTRAIT);
        } else {
            aset.add(OrientationRequested.LANDSCAPE);
        }
    
        // Print it
        job.print(doc, aset);
    } catch (PrintException e) {
