最近，项目需要为商城做一个购物小票的打印功能，日常我们去超市买东西，结账的时候收银员都会打印一个小票，一般的商城也都需要这样的一个小功能，本文给出的 demo 是在 58mm 的热敏打印机下的例子，如果是其他纸张类型的打印机，调整纸张宽度即可。

package test;

import java.awt.*;

import java.awt.print.*;

/**

* 打印机测试类(58mm)

* 1、目标打印机必须设置为默认打印机

* 2、打印页面的宽度和具体的打印机有关，一般为打印纸的宽度，需要配置成系统参数

* 3、一个汉字的宽度大概是12点

总结

简单说就是编写一段Java程序，将输出结果另存为“ *.xps  ”格式文件，由打印机输出，非常简单。希望对大家有所帮助。如有问题欢迎留言指出。感谢朋友们对本站的支持。
