如何使用 c# 设置打印机设置？

Question

编辑 我试图重构我不再需要展示的代码。我认为这只是打印机设置类的一个限制，它没有公开可以通过使用对话框来选择的功能。看来我应该能够配置一个printerSettings对象并将其分配给一个PrintDocument，然后打印那个PrintDocument ...？？？我是不是在这里思考？

再次编辑 我认为所有的二传手都坐在'printerSettings.DefaultPageSettings'。这将允许我修改打印机设置。我还没有证明，以后会证明的

PrintDocument pd = new PrintDocument();
pd.DocumentName = "test.doc";

PrinterSettings printerSettings = new PrinterSettings();
printerSettings.?? <- I want to set the printer setting here e.g. DL, A4, etc
pd.PrinterSettings = printerSettings;
pd.Print();

我在 c# 中生成了 word 邮件合并文档（支票、信件、文档），但所有这些都需要不同的打印机设置（支票 = 自定义设置，字母 = DL Env，文档 = A4）

我保存了这些设置，并且可以在加载打印机首选项对话框时访问它们，但我希望能够将其构建到代码中，而不是手动更改打印机设置。我环顾四周，似乎打印机设置类应该是它，但我似乎无法让它工作。

我正在尝试做的示例伪代码

//create the mail merge
IList<Letter> letters = MailMerge.Create(enum.letters)
Printer.Print(letters) //<-- in here I am trying set the printing preferences to DL Env


//create the mail merge
IList<Document> docs = MailMerge.Create(enum.documents)
Printer.Print(docs) //<-- in here I am trying set the printing preferences to A4

任何帮助表示赞赏。

谢谢

您或许可以使用 WMI。我唯一的 WMI 经验是一些用于 WMI 的 C# 代码来检索一些打印机属性，我没有尝试设置任何打印机属性，但我认为它应该是可能的。也许这些 MSDN 链接和代码可以帮助您入门。

WMI Tasks: Printers and Printing 显示 VB 脚本中的命令。 How To: Retrieve Collections of Managed Objects 展示了如何使用 SelectQuery 和枚举。 How To: Execute a Method 展示了如何执行一个方法:-)。

编辑：我刚刚注意到这个StackOverflow article: How do I programatically change printer settings ...，它似乎使用 WMI 来更改一些打印机设置。

我的检索代码如下所示：

    //using System.Management;

    private void GetPrinterProperties(object sender, EventArgs e)
    {
        // SelectQuery from:
        //    http://msdn.microsoft.com/en-us/library/ms257359.aspx
        // Build a query for enumeration of instances
        var query = new SelectQuery("Win32_Printer");
        // instantiate an object searcher
        var searcher = new ManagementObjectSearcher(query); 
        // retrieve the collection of objects and loop through it
        foreach (ManagementObject lPrinterObject in searcher.Get())
        {
            string lProps = GetWmiPrinterProperties(lPrinterObject);
            // some logging, tracing or breakpoint here...
        }
    }

    // log PrinterProperties for test-purposes
    private string GetWmiPrinterProperties(ManagementObject printerObject)
    {
        // Win32_Printer properties from:
        //    http://msdn.microsoft.com/en-us/library/aa394363%28v=VS.85%29.aspx
        return String.Join(",", new string[] {
                GetWmiPropertyString(printerObject, "Caption"),
                GetWmiPropertyString(printerObject, "Name"),
                GetWmiPropertyString(printerObject, "DeviceID"),
                GetWmiPropertyString(printerObject, "PNPDeviceID"),
                GetWmiPropertyString(printerObject, "DriverName"),
                GetWmiPropertyString(printerObject, "Portname"),
                GetWmiPropertyString(printerObject, "CurrentPaperType"),
                GetWmiPropertyString(printerObject, "PrinterState"),
                GetWmiPropertyString(printerObject, "PrinterStatus"),
                GetWmiPropertyString(printerObject, "Location"),
                GetWmiPropertyString(printerObject, "Description"),
                GetWmiPropertyString(printerObject, "Comment"),
            });
    }

    private string GetWmiPropertyString(ManagementObject mgmtObject, string propertyName)
    {
        if (mgmtObject[propertyName] == null)
        {
            return "<no "+ propertyName + ">";
        }
        else
        {
            return mgmtObject[propertyName].ToString();
        }
    }
}

    private void startPrintingButton_Click(object sender, EventArgs e)
    {
        OpenFileDialog ofd = new OpenFileDialog();
        if (DialogResult.OK == ofd.ShowDialog(this))
        {
            PrintDocument pdoc = new PrintDocument();

            pdoc.DefaultPageSettings.PrinterSettings.PrinterName = "ZDesigner GK420d";
            pdoc.DefaultPageSettings.Landscape = true;
            pdoc.DefaultPageSettings.PaperSize.Height = 140;
            pdoc.DefaultPageSettings.PaperSize.Width = 104;

            Print(pdoc.PrinterSettings.PrinterName, ofd.FileName);
        }
    }

    private void Print(string printerName, string fileName)
    {
        try
        {
            ProcessStartInfo gsProcessInfo;
            Process gsProcess;

            gsProcessInfo = new ProcessStartInfo();
            gsProcessInfo.Verb = "PrintTo";
            gsProcessInfo.WindowStyle = ProcessWindowStyle.Hidden;
            gsProcessInfo.FileName = fileName;
            gsProcessInfo.Arguments = "\"" + printerName + "\"";
            gsProcess = Process.Start(gsProcessInfo);
            if (gsProcess.HasExited == false)
            {
                gsProcess.Kill();
            }
            gsProcess.EnableRaisingEvents = true;

            gsProcess.Close();
        }
        catch (Exception)
        {
        }
    }
