关于医院精确套打发票的实现

      某同学医院收费系统的开发公司倒闭，现在用的半死不活，勉强可以凑合用，只是可以打印药品清单，没有提供发票格式打印。原来发票是一个古老的dos版本票据打印软件，现在要求增加一项公费医疗，要求打印公费医疗支付比例。所以让我帮他搞定这个问题

     现在软件是实现了他们要求打印的功能，我也受了很多折磨，查阅了很多资料，差点万念俱灰了。

    我把我碰到的问题一一列出，并给出我的方案，源码太简单就不贴出来了，需要人找我我会发给你们参考。高手就不要笑话俺们这些个低手了，俺们需要不断的学习的

    1.首要问题是针式打印机自定义纸张大小问题？

        /// 打印机纸张的真正自定义部分代码

       他们提供一个解决方案，调用api 实现自定义纸张大小的方法，这个是解决问题的关键，需要的去网上搜索他们的源码。

     2. 小写金额转换大写的转换问题?

 我用一个类实现    

 class Bigconvert
    {
        const string z0 = "零";
        const string z1 = "壹";
        const string z2 = "贰";
        const string z3 = "叁";
        const string z4 = "肆";
        const string z5 = "伍";
        const string z6 = "陆";
        const string z7 = "柒";
        const string z8 = "捌";
        const string z9 = "玖";
      //  const string z10 = "拾";

        private string wan;

        public string Wan
        {
            get { return wan; }
            set { wan = value; }
        }
        private string qian;
        public string Qian
        {
            get { return qian; }
            set { qian = value; }
        }
        private string bai;
        public string Bai
        {
            get { return bai; }
            set { bai = value; }
        }
        private string shi;
        public string Shi
        {
            get { return shi; }
            set { shi = value; }
        }
        private string yuan;
        public string Yuan
        {
            get { return yuan; }
            set { yuan = value; }
        }
        private string jiao;
        public string Jiao
        {
            get { return jiao; }
            set { jiao = value; }
        }
        private string fen;
        public string Fen
        {
            get { return fen; }
            set { fen = value; }
        }
        public static string z1daoyi(char   i)
        {
            switch (i)
            {
                case  '0':
                    return z0;
                  
                case ' ':
                    return z0;
                  
                case '1':
                    return z1;
                  
                case'2':
                    return z2;
                   
                case '3':
                    return z3;
                   
                case '4':
                    return z4;
                  
                case '5':
                    return z5;
                  
                case '6':
                    return z6;
                  
                case '7':
                    return z7;
                  
                case '8':
                    return z8;
                  
                case '9':
                    return z9;
                  
               default :
                   return "";
                   

              

            }
        }
        public static Bigconvert dx(string str)
        {
            Bigconvert dd = new Bigconvert();
            char[] je =shoujuprint.Convert8(str).ToCharArray();
            for (int i = 0; i <= 7; i++)
            {
                switch (i)
                {
                    case 0:
                        dd.Wan = Bigconvert.z1daoyi(je[i]);
                        break;
                    case 1:
                        dd.Qian = Bigconvert.z1daoyi(je[i]);
                        break;
                    case 2:
                        dd.Bai = Bigconvert.z1daoyi(je[i]);
                        break;
                    case 3:
                        dd.Shi = Bigconvert.z1daoyi(je[i]);
                        break;
                    case 4:
                        dd.Yuan = Bigconvert.z1daoyi(je[i]);
                        break;
                    case 5:
                        break;
                    case 6:
                        dd.Jiao = Bigconvert.z1daoyi(je[i]);
                        break;
                    case 7:
                        dd.Fen = Bigconvert.z1daoyi(je[i]);
                        break;
                   
                       

                }

            }
            return dd;

        }
    }

3.发票上项目金额小写右对齐问题？

我只是实现5位数字的不超过万位，

 class fpshuziyouduiqi

    {
        public static  string Convert8(string str)
        {
            if (str == "")
                return "";
            else
            {
                string i = "";
                i = string.Format("{0:00000.00}", Convert.ToDouble(str));
                return zh(i);
            }

        }
       private static string zh(string a)
        {
            string b = "";

            char[] d = a.ToCharArray();

            for (int i = 0; i <= 7; i++)
            {
                if (i == 4 && d[4] == '0')
                {
                    b = "    0";
                    b += d[5];
                    b += d[6];
                    b += d[7];
                    return b;
                }

                if (d[i] == '0')
                    b += " ";
                else
                {
                    for (int j = i; j <= 7; j++)
                    { b += d[j]; }
                    return b;
                }
            }
           return b;
        }

}

4，打印事件实现？

       
            其他都跟文本打印一样，不熟悉的看看帮助文档，主要是设置绘制的单位为毫米，就可以精确控制了打印输出了
           就是这个 g.PageUnit = GraphicsUnit.Millimeter;

以上为基本思路，有些网友说用水晶报表解决，水晶报表我还没有去研究，有了这个思路，基本上解决其他精确套打的比如支票，快递单据都应该可以解决了。

希望对这个问题困惑的朋友能够多个小提示。可以qq跟我交流106782465
