winform 小票打印

打印代码 ，中间是小票的格式 path自己定义一个路径，有些变量你可以根据需要设置
方法和打印事件外面声明

// 小票打印
 StreamWriter sw = new StreamWriter(path, true);
 strRiqi = DateTime.Now.ToString("yyyyMMdd");
 strShijian = DateTime.Now.ToString("HHmmss");

 sw.Write(" 冲正凭证\t\t");
 sw.WriteLine(" \t");
 sw.WriteLine(" \t");
 sw.Write("卡号 \t");
 sw.WriteLine(strKaID);
 sw.Write("卡类型 \t");
 sw.WriteLine(strKaLeixing);
 sw.Write("卡有效期 \t");
 sw.WriteLine(strKaYouxiaoqi);
 sw.Write("网点编号 \t");
 sw.WriteLine(strWangdianBianhao);
 sw.Write("冲正前金额 \t");
 sw.WriteLine(strChongzhiqianJine);
 sw.Write("冲正金额 \t");
 sw.WriteLine(strChongzhiJine);
 sw.Write("冲正后金额 \t");
 sw.WriteLine(strChongzhiHouJine);
 sw.Write("日期 \t");
 sw.WriteLine(strRiqi);
 sw.Write("时间 \t");
 sw.WriteLine(strShijian);
 sw.Write("操作员 \t");
 sw.WriteLine(ShareMemory.StrBianhao);
 sw.Write("客服电话 \t");
 sw.WriteLine(strKefuDianhua);
 sw.WriteLine(" ");
 sw.Write("XXXX科技有限公司");
 sw.Close();
