java windows下打印机操作

1、获取Windows所有打印机

public List list getPrints() {
  /*HashPrintRequestAttributeSet pras = new HashPrintRequestAttributeSet();
  DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE;
  // 查找所有的可用的打印服务
  PrintService[] printService = PrintServiceLookup.lookupPrintServices(
    flavor, pras);*/
  PrintService[] pss = PrinterJob.lookupPrintServices();
     PrintService ps = null;
  Listlist = new ArrayList();
  /*for (int i = 0; i < printService.length; i++) {
   // System.out.println(printService[i].getName());
   Hashtable ht = new Hashtable();
   ht.put("printName", printService[i].getName());
   list.add(ht);
  }*/
  for (int i = 0; i < pss.length; i++) {
        String sps = pss[i].toString();
        sps = sps.replace("Win32 Printer : ", "");
        Hashtable ht = new Hashtable();
        //logger.info("打印机："+sps);
        ht.put("printName", sps);
        list.add(ht);
  }
  return list;
 }

2、将jasper内容输入到指定的打印机

public static boolean directPrintByPrintName(final JasperPrint jasperPrint,
   String printName) {
  if (jasperPrint != null) {
   try {
    PrintService[] PSs = PrinterJob.lookupPrintServices(); // java.awt.*包.查找所有打印服务.
    PrintService ps = null;
    if (PSs != null && PSs.length > 1 && printName != null
      && !printName.equals("")) {
     for (int i = 0; i < PSs.length; i++) {
      String sps = PSs[i].toString();
      sps = sps.replace("Win32 Printer : ", ""); //$NON-NLS-1$ //$NON-NLS-2$

      // printName 我们系统设置的默认打印机名称.
      if (sps.equalsIgnoreCase(printName)) {
       ps = PSs[i];// 得到打印服务对象
       break;
      }
     }
    }
    // 设置打印参数,好多个参数
    if (ps != null) {
     long start = System.currentTimeMillis();
     //PrintRequestAttributeSet printRequestAttributeSet = new HashPrintRequestAttributeSet();
     // printRequestAttributeSet.add(MediaSizeName.ISO_A5);//
     // 处方模板是A5纸 第一个参数对象
     //MediaSize ms = new MediaSize(280,380.0f,Size2DSyntax.MM,MediaSizeName.ISO_A3);
     //printRequestAttributeSet.add(ms.getMediaSizeName());
     PrintServiceAttributeSet printServiceAttributeSet = new HashPrintServiceAttributeSet();
     printServiceAttributeSet.add(new PrinterName(ps.getName(),
       null)); // 第二个参数对象

     final JRPrintServiceExporter exporter = new JRPrintServiceExporter(); // 关键的对象,其它的对象都是为他服务的
     // 以下为设置参数
     exporter.setParameter(JRExporterParameter.JASPER_PRINT,
       jasperPrint);
     /*
      * exporter.setParameter(JRPrintServiceExporterParameter.
      * PRINT_REQUEST_ATTRIBUTE_SET, printRequestAttributeSet);
      */
     exporter.setParameter(
       JRPrintServiceExporterParameter.PRINT_SERVICE_ATTRIBUTE_SET,
       printServiceAttributeSet);
     exporter.setParameter(
       JRPrintServiceExporterParameter.DISPLAY_PAGE_DIALOG,
       Boolean.FALSE);
     exporter.setParameter(
       JRPrintServiceExporterParameter.DISPLAY_PRINT_DIALOG,
       Boolean.FALSE);
     // 关键的出场,在线程里导出报表.(打印)

     Thread thread = new Thread(new Runnable() {
      public void run() {
       try {
        exporter.exportReport(); // 就这么一句.exporter对象导出报表.
       } catch (Exception ex) {
        System.err.println(ex.getLocalizedMessage());
        logger.error(ContextUtil.getTrace(ex));
       }
      }
     });
     thread.start();

    } else { // //7.采用默认打印.
     Thread thread = new Thread(new Runnable() {
      public void run() {
       try {
        // jasperPrint
        // 对象就是JasperPrintManager生成的.参考上面的代码.
        JasperPrintManager.printReport(jasperPrint,
          false); // 这一句应该是默认打印.
       } catch (Exception ex) {
        logger.error(ContextUtil.getTrace(ex));
       }
      }
     });
     thread.start();
    }
   } catch (Exception ex) {
    logger.error(ContextUtil.getTrace(ex));
    return false;
   }

  }
  return true;
 }
