我正在使用此代码在纸上打印:
//Overriden from printable interface
public int print(Graphics g, PageFormat pageFormat, int pageIndex)
throws PrinterException {
if (pageIndex != 0) {
return Printable.NO_SUCH_PAGE;
}
Paper a4 = new Paper();
a4.setImageableArea(0, 0, a4.getWidth(), a4.getHeight());
pageFormat.setPaper(a4);
pageFormat.setOrientation(PageFormat.PORTRAIT);
Graphics2D g2d = (Graphics2D)g;
//g2d.translate(pageFormat.getImageableX(), pageFormat.getImageableY());
this.setDoubleBuffered(false);
panel.print(g2d);
JOptionPane.showMessageDialog(null, new ImageIcon(image));
this.setDoubleBuffered(true);
return Printable.PAGE_EXISTS;
}
我试图以编程方式减小边距的大小.无论我做什么,图像的两侧似乎总有一个大块缺失(除非我从打印对话框中删除边距 – 但正如我所说,我想以编程方式删除它们以使整个过程自动化).
最佳答案 例如,
US Letter尺寸的纸张尺寸为8½x11英寸.每英寸72点,即612 x 792.
在选择了该尺寸纸张的典型打印机上,PageFormat
对象报告以下区域.
System.out.println(pf.getImageableX() + " " + pf.getImageableY()
+ " " + pf.getImageableWidth() + " " + pf.getImageableHeight());
18.0 18.0 576.0 734.0 18.0 18.0 576.0 734.0
很少有消费者打印机是full-bleed,因此可打印区域小于纸张的物理尺寸.实际上,打印机无法将墨水放在无法打印的地方.
