Question

我在印刷面板上遇到问题。在我的打印页面中，内容的两侧都有不需要的边距，内容区域太小而无法包含该面板中的所有文本。所以...我的结果页面是....... My Picture

我的代码在这里......

}

}

Answer 1

尝试设置p3的大小，以便在调用PageFormat方法时满足print的页面大小。

 Rectangle bounds = p3.getBounds();
 p3.setBounds(0, 0, (int)pf.getWidth(), (int)pf.getHeight());
 p3.printAll(g);
 p3.setBounds(bounds);
