Force target printer in Java

Question

Is there a way to force the target printer in java, using HashPrintRequestAttributeSet ?

I don\'t want the user to be able to change the printer in the printdialog

Answer 1

I just solved this problem by running cmd command in Java

static void changeWindowsDefaultPrinter(String printerName) {
    String cmdLine  = String.format("RUNDLL32 PRINTUI.DLL,PrintUIEntry /y /n \"%s\"", printerName);
    ProcessBuilder builder = new ProcessBuilder("cmd.exe", "/c", cmdLine );
    builder.redirectErrorStream(true);
    Process p = null;
    try { p = builder.start(); }
    catch (IOException e) { e.printStackTrace(); }

    BufferedReader r = new BufferedReader(new InputStreamReader(p.getInputStream()));
    String line = new String();
    while (true) {
        try {
            line = r.readLine();
        } catch (IOException e) {
            e.printStackTrace();
        }
        if (line == null) { break; }
        System.out.println( "result  "  + line);
    }
}

And It's Wroked for Me :D
