Forza stampante target in Java

Question

C'è un modo per forzare la stampante di destinazione in java, utilizzando HashPrintRequestAttributeSet?

Non voglio che l'utente sia in grado di cambiare la stampante nelle PrintDialog

Grazie

Answer 1

dovuto capire questo nel modo più duro, ma anche per le generazioni future, ecco alcuni dei miei codice:

PrintService[] printServices; 
PrintService printService; 
PageFormat pageFormat; 

String printerName = "Your printer name in Devices and Printers"; 

PrintServiceAttributeSet printServiceAttributeSet = new HashPrintServiceAttributeSet(); 
printServiceAttributeSet.add(new PrinterName(printerName, null)); 
printServices = PrintServiceLookup.lookupPrintServices(null, printServiceAttributeSet); 

pageFormat = new PageFormat(); // If you want to adjust heigh and width etc. of your paper. 
pageFormat = printerjob.defaultPage(); 

PrinterJob printerjob = PrinterJob.getPrinterJob(); 

printerjob.setPrintable(new Server(), pageFormat); // Server was my class's name, you use yours. 

try { 
    printService = printServices[0]; 
    printerjob.setPrintService(printService); // Try setting the printer you want 
} catch (ArrayIndexOutOfBoundsException e) { 
    System.err.println("Error: No printer named '" + printerName + "', using default printer."); 
    pageFormat = printerjob.defaultPage(); // Set the default printer instead. 
} catch (PrinterException exception) { 
    System.err.println("Printing error: " + exception); 
} 

try { 
    printerjob.print(); // Actual print command 
} catch (PrinterException exception) { 
    System.err.println("Printing error: " + exception); 
} 

Answer 2

il mio codice per risolvere questo:

String printerNameDesired = "My Printer"; 

PrintService[] service = PrinterJob.lookupPrintServices(); // list of printers 

int count = service.length; 

for (int i = 0; i < count; i++) { 
    if (service[i].getName().equalsIgnoreCase(printerNameDesired)) { 
     docPrintJob = service[i].createPrintJob(); 
     i = count; 
    } 
} 
PrinterJob pjob = PrinterJob.getPrinterJob(); 
pjob.setPrintService(docPrintJob.getPrintService()); 
pjob.setJobName("job"); 
pjob.print();

Ho appena risolto questo problema eseguendo il comando cmd 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); 
    } 
}
