我如何打印我的面板，从 (locationx,locationy) 到 (panel.getWidth(),panel.getHeight())？

我有这个链接，我可以使用这个示例来打印我的面板：打印示例我用它来打印我的面板：

PrintUtilities.printComponent(this);

“this”是面板。但打印后，纸上的面板并不满。仅（大约）宽度的 70% 和高度的 60%。（抱歉我的英语，我是匈牙利语）面板尺寸为：850x1160。这是 A4 纸的示例尺寸：595x842 -> 70dpi=A4。请帮助我，如何将我的面板完全打印到 A4 纸上。谢谢你！

double factorX = pf.getImageableWidth() / component.getWidth();
double factorY = pf.getImageableHeight() / component.getHeight();
double factor = Math.min( factorX, factorY );
g2.scale(factor,factor);

谢谢大家的回答！

double factorX = pf.getImageableWidth() / component.getWidth();
double factorY = pf.getImageableHeight() / component.getHeight();
double factor = Math.min( factorX, factorY );
