java - JPanel 字体与打印输出不匹配

Question

我想通过热敏打印机打印我的 jpanel。但是当我打印面板时，输出的字体与面板字体不匹配。面板有 JLabels 和图像。我已经发送了下面的代码。如果您能提供帮助，我将非常感激!

public static class Printer implements Printable {
    final Component comp;

    public Printer(Component comp) {
        this.comp = comp;
    }

    @Override
    public int print(Graphics g, PageFormat format, int page_index)
            throws PrinterException {
        if (page_index > 0) {
            return Printable.NO_SUCH_PAGE;
        }

        // get the bounds of the component
        Dimension dim = comp.getSize();
        double cHeight = dim.getHeight();
        double cWidth = dim.getWidth();

        // get the bounds of the printable area
        double pHeight = format.getImageableHeight();
        double pWidth = format.getImageableWidth();

        double pXStart = format.getImageableX();
        double pYStart = format.getImageableY();

        double xRatio = pWidth / cWidth;
        double yRatio = pHeight / cHeight;

        Graphics2D g2 = (Graphics2D) g;


        g2.translate(pXStart, pYStart);
        g2.scale(xRatio, yRatio);
        comp.paint(g2);

        return Printable.PAGE_EXISTS;
    }
}

您必须为所有子组件设置所需的字体。将字体设置为所有标签，因为它们不使用父级的字体。
