java打印功能(熟悉java打印的请帮个忙)

没做过，我手头有一个别人写的打印的源程序，给你参考一下吧
package print;/**
 * 一个单页打印程序具体用法如下：
 * new SinglePagePrint(this.WellCanvas).start();
*/
import java.awt.Component;
import java.awt.print.*;public class SinglePagePrint
        extends Thread {
    Component myComponent;
    public SinglePagePrint(Component component)
    {
        this.myComponent = component;
    }    public void run()
    {
        PrinterJob job = PrinterJob.getPrinterJob();
        Book book = new Book();
        PageFormat pf = job.pageDialog(job.defaultPage());
        SinglePrint pff = new SinglePrint(this.myComponent);
        book.append(pff, pf, 1);
        job.setPageable(book);
        if (job.printDialog()) {
            try {
                job.print();
            }
            catch (PrinterException e) {
                e.printStackTrace();
            }
        }
    }
}
