怎样把java输出流输出到打印机上呢？3

 

有两个需求，一个是把文件下载下来，这个好办；另一个是点击一个链接，直接把文件打印出来，当然中间要有打印机的选择过程。怎样才能把java输出流输出到打印机上呢？
问题补充：
这个不是我想要的。我是想把输出流连到打印机。就像在页面里右击--打印弹出打印对话框出来的效果一样。另外，javascript:window.print()只是打印所在页面。

或者你可以变通一下,将你的输出流,输出到一个jsp页面上,弄一个打印的按钮让用户去点,就可以解决了呀.没有必要 一定要用输出流来打印吧.

你要在jsp页面上点击一个链接实现java的打印不可行.

java调用打印机的范例:

import java.awt.print.PrinterJob;
import java.awt.print.Book;
import java.awt.print.Printable;
import java.awt.Graphics;
import java.awt.print.PageFormat;
import java.awt.print.PrinterException;
import javax.print.PrintService;
import javax.print.PrintServiceLookup;
import java.awt.Graphics2D;
import java.awt.Color;
import java.awt.Font;
import javax.print.attribute.HashAttributeSet;
import javax.print.attribute.standard.PrinterName;

public class MyPrintTest
    implements Printable
{
  public int print(Graphics graphics, PageFormat pageFormat, int pageIndex)
      throws PrinterException
  {
    Graphics2D g2 = (Graphics2D) graphics;
    g2.setPaint(Color.black);
    g2.translate(pageFormat.getImageableX(), pageFormat.getImageableY());
    Font font = new Font("宋体", Font.BOLD, 10);
    g2.setFont(font);
    g2.drawString("afasdfad",  10, 10);
    font = new Font("黑体", Font.ITALIC, 18);
    g2.setFont(font);
    g2.drawString("第二行:", 10, 40);
    return Printable.PAGE_EXISTS;
  }

  public static void main(String[] args)
  {
    MyPrintTest myprinttest = new MyPrintTest();
    myprinttest.print();
  }

  public void print()
  {
    PrinterJob printerJob = PrinterJob.getPrinterJob();
    Book book = new Book();
    book.append(new MyPrintTest(), printerJob.defaultPage());
    printerJob.setPageable(book);
    HashAttributeSet hs = new HashAttributeSet();
    String printerName="EPSON TM-U220 Receipt";
    hs.add(new PrinterName(printerName,null));
    PrintService[] pss = PrintServiceLookup.lookupPrintServices(null, hs);
    if(pss.length==0)
    {
      System.out.println("无法找到打印机:"+printerName);
      return ;
    }
    try
    {
      printerJob.setPrintService(pss[0]);
      printerJob.print();
    }
    catch (PrinterException ex)
    {
      System.out.println(ex.getMessage());
