从Windows窗体打印的工具

Question

因此，我需要从Windows窗体应用程序（c＃，.net 4）打印到激光打印机，并且我发现了超级“有趣”的PrintDocument类，现在有可用的代码，但它看起来像这样：

private void PrintCollate(vws.custom.production.IndiPackLabel ipl) 
    { 
     var pd = new PrintDocument(); 
     pd.DocumentName = "Collate"; 
     var printerSettings = new System.Drawing.Printing.PrinterSettings(); 
     printerSettings.PrinterName = "HP LaserJet 4100"; 
     pd.PrinterSettings = printerSettings; 
     pd.PrinterSettings.Copies = 1; 
     _currCollate = ipl; 
     pd.PrintPage += new PrintPageEventHandler(pd_PrintPage); 
     pd.Print(); 
     _currCollate = null; 
    } 

    private static vws.custom.production.IndiPackLabel _currCollate; 

    public void pd_PrintPage(Object sender, System.Drawing.Printing.PrintPageEventArgs e) 
    { 
     float linesPerPage = 0; 

     //int count = 0; 
     float leftMargin = 20; 
     float topMargin = 20; 

     float yPos = topMargin; 


     var printFontNormal = new System.Drawing.Font("consolas", 10); 
     var printFontNormalBold = new System.Drawing.Font("consolas", 10, FontStyle.Bold); 
     float stdFontHeight = printFontNormal.GetHeight(e.Graphics); 

     var printFontSmall = new System.Drawing.Font("consolas", 8); 
     float smallFontHeight = printFontSmall.GetHeight(e.Graphics); 

     linesPerPage = e.MarginBounds.Height/stdFontHeight; 

     e.Graphics.DrawString(("Order: " + _currCollate.OrderDescription).PadRight(91) + "ORD #:" + _currCollate.OrderNumber, printFontNormal, Brushes.Black, leftMargin, yPos); 
     yPos += stdFontHeight; 

     string customerInfo = (_currCollate.Customer.FirstName + " " + _currCollate.Customer.LastName).PadRight(90) + " BAG #" + _currCollate.BagNumber; 
     e.Graphics.DrawString(customerInfo, printFontNormal, Brushes.Black, leftMargin, yPos); 
     yPos += stdFontHeight; 
     yPos += stdFontHeight; 

     string header = "ITEMNO".PadRight(20) + "ITEM NAME".PadRight(70) + "QTY".PadRight(3); 
     e.Graphics.DrawString(header, printFontNormalBold, Brushes.Black, leftMargin, yPos); 

     int itemTotal = 0; 

     foreach (var item in _currCollate.OrderItems) 
     { 
      yPos += stdFontHeight; 
      string itemLine = item.ItemNo.PadRight(20) + (item.ItemName + " " + item.OptionNames).PadRight(70) + item.Qty.ToString().PadRight(3); 
      e.Graphics.DrawString(itemLine, printFontNormal, Brushes.Black, leftMargin, yPos); 

      if (item.Notes.Length > 0) 
      { 
       yPos += stdFontHeight; 
       string notesLine = string.Empty.PadRight(20) + item.Notes; 
       e.Graphics.DrawString(notesLine, printFontNormal, Brushes.Black, leftMargin, yPos); 
      } 

      itemTotal += item.Qty; 
     } 

     yPos += stdFontHeight; 
     string footer = "TOTAL ITEMS: ".PadRight(90) + itemTotal; 
     e.Graphics.DrawString(footer, printFontNormal, Brushes.Black, leftMargin, yPos); 

     e.Graphics.DrawRectangle(new Pen(Color.Black, 2), new Rectangle(20,600,700,500)); 
    } 

必须有更好的方法。特别是当我必须在6个月内改变这一点，并且必须重新计算出来。

我正在使用Neodynamic的热敏标签SDK（http://www.neodynamic.com/ND/ProductsPage.aspx?tabid=10 & prod = thermallabel）来打印Zebra打印机，并希望有类似的API用于创建激光打印机的打印文档。我还需要在此打印文档中添加条形码打印，因此，包含条形码功能的任何工具都会更有帮助。

有什么建议吗？

如果你需要你的窗口打印在屏幕上的exacly打印，我会建议使用DrawToBitmap方法。更多细节：How to get a screen capture of a .Net control programmatically。这种方法也适用于复合控件（例如整个表单）。

如果您需要更高级的打印功能，我建议您寻找.NET的一些“报告库”（可能是其中之一：Report Viewer/Crystal Reports/SQL Server Reporting Services）。虽然我不能给出任何详细的指导，因为我还没有使用过它们中的任何一个。
