如何利用ireport实现打印条码标签

Answer 1

利用ireport实现打印条码标签
上个星期做了一个用ireport打印条码标签的需求，其实有打印条码有很多专门的软件，例如ZebraDesigner，但是ireport可以和java结合起来，使用起来比较方便，现简要叙述一下过程：
　　1、打开ireport，新建一个文档，用鼠标点击图标拖拽到文档里，这里不累述ireport的使用方法，ireport的使用说明书可以到网上下载。
　　2、双击，打开它的属性框，选择图片栏，在图片表达式里输入条码转换的方法，可以查阅如下代码：
　　3、注意图片表达式类选择java.awt.Image
