Java print API send commands to printer

I have got some printers well installed on my computer (Windows 7) and well displayed on the control panel.

I would like to send some special commands like: cut command, or barcode printing commands (ESC/POS commands).

Is it possible to do that using Java Print API ? or does Java Print API perform only printing services ?

Thanks in advance.

Problem solved : Thanks to VGR.

here's a code to help anyone having same problem:

private PrintService printer = ...; // init this using PrintService.lookupPrintServices();

if(this.printer != null) {
        String commandToSend = "Some command\n";

        Doc myDoc = new SimpleDoc(commandToSend.getBytes(), DocFlavor.BYTE_ARRAY.AUTOSENSE, null);
        DocPrintJob job = this.printer.createPrintJob();

        try {
            job.print(myDoc, null);
        } catch (PrintException e) {
            e.printStackTrace();
        }
    }
