After reading through this Q&A I spent awhile working with the javax.print library only to discover that it is not very consistent with printer option support. I.e. even if a printer has an option like stapling, the javax.printer library showed it as "stapling not supported".

So I then tried out PJL commands using a plain java socket and it worked great, in my tests it also printed faster than the javax.print library, it has a much smaller code footprint and best part is no libraries are needed at all:

private static void print(File document, String printerIpAddress)
{
    try (Socket socket = new Socket(printerIpAddress, 9100))
    {
        DataOutputStream out = new DataOutputStream(socket.getOutputStream());
        String title = document.getName();
        byte[] bytes = Files.readAllBytes(document.toPath());

        out.write(27);
        out.write("%-12345X@PJL\n".getBytes());
        out.write(("@PJL SET JOBNAME=" + title + "\n").getBytes());
        out.write("@PJL SET DUPLEX=ON\n".getBytes());
        out.write("@PJL SET STAPLEOPTION=ONE\n".getBytes());
        out.write("@PJL ENTER LANGUAGE=PDF\n".getBytes());
        out.write(bytes);
        out.write(27);
        out.write("%-12345X".getBytes());
        out.flush();
        out.close();
    }
    catch (Exception e)
    {
        System.out.println(e);
    }
}
