Answer 1

试过了，但是默克大哥提供的代码没有涉及到我的问题。该代码结果是可以打印，但我希望是把纵向改为横向，这样才有利于输出表格，我用setOrientation（）方法设置LANDSCAPE参数后，横向打印实现了，但可打印区域似乎并没有改变，以至于A4幅面的纸横向时右侧总有一部分区域无法打印。也就是
g.drawString("aa6",640,251);
g.drawString("aa5",540,251);
g.drawString("aa4",455,251);
g.drawString("aa3",340,251);
g.drawString("aa0",70,251);
里面的aa5之后的信息无法打印。
我调过setImageableWidth（），但不能解决问题。

Answer 2

将Paper的属性设置为A4纸就可以了，一般都用的A4纸,这问题我门以前也遇到过.

Answer 3

哈哈，问题终于解决了。
关键不在于设ImageableArea（），而是设Graphics的Clip。只有改变了Graphics的Clip大小，才会影响打印范围。
