用于从Windows窗体打印的工具

Question

因此，我需要从windows表单应用程序(c#、.net 4)打印到激光打印机，我发现了超级“有趣”的PrintDocument类，现在有了可以工作的代码，但它看起来如下所示：

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));
    }

一定有更好的方法。尤其是当我必须在6个月内改变这一点，并不得不重新弄清楚这一点的时候。

我正在使用Neodynamic的热敏标签开发工具包(http://www.neodynamic.com/ND/ProductsPage.aspx?tabid=107&prod=thermallabel)来打印到Zebra打印机，并希望有一个类似的应用程序接口来为激光打印机创建打印文档。我还需要将条形码打印添加到此打印文档中，因此任何包含条形码功能的工具都会更有帮助。

有什么建议吗？

如果你想让你的windows窗体完全按照屏幕上的显示方式打印出来，我建议你使用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，我建议您寻找一些用于.NET的“报告库”(可能是其中之一：Report Viewer / Crystal Reports / SQL Server Reporting Services)。不过，我不能给出任何详细的指导，因为我自己还没有用过任何一个。
