Java Applet可以使用打印机吗？

Java Applet能够轻松打印文本/ HTML到标准的打印机驱动程序(所有常见的平台Win / Mac / Linux)？

需要签名吗？

解决方法

以下是使用JEditorPane打印HTML的一些示例代码：

public class HTMLPrinter implements Printable{
    private final JEditorPane printPane;

    public HTMLPrinter(JEditorPane editorPane){
        printPane = editorPane;
    }

    public int print(Graphics graphics,PageFormat pageFormat,int pageIndex){
        if (pageIndex >= 1) return Printable.NO_SUCH_PAGE;

        Graphics2D g2d = (Graphics2D)graphics;
        g2d.setClip(0,(int)pageFormat.getImageableWidth(),(int)pageFormat.getImageableHeight());
        g2d.translate((int)pageFormat.getImageableX(),(int)pageFormat.getImageableY());

        RepaintManager rm = RepaintManager.currentManager(printPane);
        boolean doubleBuffer = rm.isDoubleBufferingEnabled();
        rm.setDoubleBufferingEnabled(false);

        printPane.setSize((int)pageFormat.getImageableWidth(),1);
        printPane.print(g2d);

        rm.setDoubleBufferingEnabled(doubleBuffer);

        return Printable.PAGE_EXISTS;
    }
}

然后发送到打印机：

HTMLPrinter target = new HTMLPrinter(editorPane);
PrinterJob printJob = PrinterJob.getPrinterJob();
printJob.setPrintable(target);
try{
    printJob.printDialog();
    printJob.print();
}catch(Exception e){
    e.printStackTrace();
}
