请问，发票打印和报表打印有什么不同？需要注意什么？有什么实现办法吗？

Question

因为最近在作一个医院的收费系统，需要发票打印，而且是套打，请问如何实现？以前没有作过这种小票打印，请高手指点。因为以前只作过报表打印，可是那种感觉很容易实现，可是这种以固定模式打印却不知从何下手了。哪位朋友有源码的最好能贴一点上来，也让我见识一下，少走些弯路。谢谢。

发票类似于支票。

打印依靠PringDocument实现,至于纸张设置,由用户在第一次使用时指定(也可以中途更改),但程序必须保存用户的设定,否则每次启动程序时做一次设置太不方便,保存和读取设置的代码参考下面.
        private void SavePrintSetting()
        {
            RegistryKey hKey = Registry.CurrentUser.CreateSubKey(@"Software\xxxx公司\打印设置\3.0");
            RegistryKey subKey = hKey.CreateSubKey(this.GetType().GUID.ToString("B"));
            subKey.SetValue("PaperName", this.m_PrintDoc.DefaultPageSettings.PaperSize.PaperName);
            subKey.SetValue("PaperKind", this.m_PrintDoc.DefaultPageSettings.PaperSize.Kind);
            subKey.SetValue("PaperWidth", this.m_PrintDoc.DefaultPageSettings.PaperSize.Width);
            subKey.SetValue("PaperHeight", this.m_PrintDoc.DefaultPageSettings.PaperSize.Height);
            subKey.SetValue("PaperTop", this.m_PrintDoc.DefaultPageSettings.Margins.Top);
            subKey.SetValue("PaperBottom", this.m_PrintDoc.DefaultPageSettings.Margins.Bottom);
            subKey.SetValue("PaperLeft", this.m_PrintDoc.DefaultPageSettings.Margins.Left);
            subKey.SetValue("PaperRight", this.m_PrintDoc.DefaultPageSettings.Margins.Right);
            subKey.SetValue("PrinterName", this.m_PrintDoc.PrinterSettings.PrinterName);
            subKey.SetValue("Landscape", this.m_PrintDoc.DefaultPageSettings.Landscape ? 1 : 0, RegistryValueKind.DWord);
            subKey.Close();
        }
        private void LoadPrintSetting()
        {
            RegistryKey hKey = null;
            RegistryKey subKey = null;
            bool printResult = false, paperResult = false;
            try
            {
                hKey = Registry.CurrentUser.OpenSubKey(@"Software\xxxx公司\打印设置\3.0");
                subKey = hKey.OpenSubKey(this.GetType().GUID.ToString("B"));
                string pName = subKey.GetValue("PaperName").ToString();
                System.Drawing.Printing.PaperKind pKind = (System.Drawing.Printing.PaperKind)System.Enum.Parse(typeof(System.Drawing.Printing.PaperKind),subKey.GetValue("PaperKind").ToString());
                int pWidth = (int)subKey.GetValue("PaperWidth");
                int pHeight = (int)subKey.GetValue("PaperHeight");
                string printer = subKey.GetValue("PrinterName").ToString();
                int landscape = (int)subKey.GetValue("Landscape", 0);
                foreach (string p in PrinterSettings.InstalledPrinters)
                {
                    if (p == printer)
                    {
                        this.m_PrintDoc.PrinterSettings.PrinterName = printer;
                        printResult = true;
                        break;
                    }
                }
                this.m_PrintDoc.DefaultPageSettings.Landscape = (landscape == 1);
                foreach (PaperSize pSize in this.m_PrintDoc.PrinterSettings.PaperSizes)
                {
                    if ((pSize.PaperName == pName) && (pSize.Kind == pKind) && (pSize.Width == pWidth) && (pSize.Height == pHeight))
                    {
                        this.m_PrintDoc.DefaultPageSettings.PaperSize = pSize;
                        paperResult = true;
                        break;
                    }
                }
                this.m_PrintDoc.DefaultPageSettings.Margins.Top = (int)subKey.GetValue("PaperTop");
                this.m_PrintDoc.DefaultPageSettings.Margins.Bottom = (int)subKey.GetValue("PaperBottom");
                this.m_PrintDoc.DefaultPageSettings.Margins.Left = (int)subKey.GetValue("PaperLeft");
                this.m_PrintDoc.DefaultPageSettings.Margins.Right = (int)subKey.GetValue("PaperRight");            }
            catch (Exception)
            {
                printResult = false;
            }
            finally
            {
                if (subKey != null)
                    subKey.Close();
                if (hKey != null)
                    hKey.Close();
            }            if ((!printResult) || (!paperResult))
            {
                this.SavePrintSetting();
            }
        }
