如何将JasperPrint直接打印到打印机？

Question

我使用Java创建报告JasperReports。我想要做的是该用户能够直接打印，而无需打印对话框。
我创建了JasperPrint我知道打印机的名称和型号。

我也看过sample here，但无法弄清楚如何。
我使用Java 1.7和最新的JasperReports库。

有谁知道该怎么做？

public class PrintApp { 

    public static void print() { 
     JasperPrint jasperPrint = getJasperPrint(); 
      String printername = AllPrinter.getDepartmentPrinter("Admin"); 
      // where should i introduce my printer name to jasperreports? 
      JasperPrintManager.printReport(jasperPrint, false); 
    } 

    private static JasperPrint getJasperPrint() { 
      return JasperPrinterCreator.getJasperprint(); 
    } 
}

我解决了这个问题，如下，希望它可以帮助别人。

public class PrintApp { 

    public static void print() { 
      JasperPrint jasperPrint = getJasperPrint(); 
      String selectedPrinter = AllPrinter.getDepartmentPrinter("Admin"); 

      PrinterJob printerJob = PrinterJob.getPrinterJob(); 
      PrintService[] services = PrintServiceLookup.lookupPrintServices(null, null); 
      PrintService selectedService = null; 

      if(services.length != 0 || services != null) 
      { 
       for(PrintService service : services){ 
        String existingPrinter = service.getName().toLowerCase(); 
        if(existingPrinter.equals(selectedPrinter)) 
        { 
         selectedService = service; 
         break; 
        } 
       } 

       if(selectedService != null) 
       { 
        printerJob.setPrintService(selectedService); 
        boolean printSucceed = JasperPrintManager.printReport(mainPrint, false); 
       } 
    } 

    private static JasperPrint getJasperPrint() { 
      return JasperPrinterCreator.getJasperprint(); 
    } 
}
