Java Applet可以使用打印机吗？

要进行打印，您将需要使用“
签名的小程序”，或者如果尝试打印未签名的小程序，系统将提示用户询问是否允许权限。

以下是一些使用JEditorPane打印HTML的示例代码：

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, 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;    }}

然后将其发送到打印机：

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