最近，項目需要為商城做一個購物小票的打印功能，日常我們去超市買東西，結賬的時候收銀員都會打印一個小票，一般的商城也都需要這樣的一個小功能，本文給出的 demo 是在 58mm 的熱敏打印機下的例子，如果是其他紙張類型的打印機，調整紙張寬度即可。

package test;

import java.awt.*;

import java.awt.print.*;

/**

* 打印機測試類(58mm)

* 1、目標打印機必須設置為默認打印機

* 2、打印頁面的寬度和具體的打印機有關，一般為打印紙的寬度，需要配置成系統參數

* 3、一個漢字的寬度大概是12點

簡單說就是編寫一段Java程序，將輸出結果另存為“?*.xps? ”格式文件，由打印機輸出，非常簡單。希望對大家有所幫助。如有問題歡迎留言指出。感謝朋友們對本站的支持。
