在Java中強制目標打印機

Question

有沒有辦法在java中使用HashPrintRequestAttributeSet強制目標打印機？

我不希望用戶能夠更改打印機的PrintDialog類

感謝

Answer 1

只好艱難地算出來，但對於後人，這裏是我的一些 的代碼：

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); 
}

我的代碼來解決這個問題：

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();

我只是在Java中

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); 
    } 
} 

運行cmd命令解決了這個問題，它的Wroked對我來說：d
