我要进行账单小票的打印,
我已经自定义了打印页面的高度可是打印出来的还是A4纸的高度
PageFormat pf = new PageFormat();
pf.setOrientation(PageFormat.PORTRAIT);
Paper p = new Paper();
Y = 90.00 + (list.size() * 35);
p.setSize(140.00, Y);
System.out.println("print paper Height : " + p.getHeight());
p.setImageableArea(0, 10, 140, Y);
pf.setPaper(p);
控制太輸出的print paper Height : 1730.00 这已经超出了A4高度的一倍有余 为什么还是不行?求各位大虾帮帮忙呀!!!
