如何利用Java技术高效实现批量打印功能

展开全部

下面是实现Java批量打印功能的具体工具类&＃xff0c;其中的Info类和UserClass为具体的快递面单中要打印的信息e68a8462616964757a686964616f31333363383935&＃xff0c;以参数的方式传递过来&＃xff0c;循环调用Java PrinterJob服务进行打印&＃xff1b;这里的快递尺寸已经调整好&＃xff0c;可以使用&＃xff0c;如需添加只要根据实际的面单进行调整&＃xff0c;也可以专门写一个接口类的形式来创建快递面单的尺寸&＃xff0c;本人没有尝试&＃xff1b;如遇问题欢迎留言&＃xff0c;共同探讨&＃xff01;
