Question

在我的应用程序（win10，WPF）上，我使用户可以打印报告。
但是
当本地计算机上有尚未配置的打印机时，这是不可能的。
（当然，打印机是在网络上激活的，并且通过使用settings -> add printer & sccaners可以找到并安装）

我已经在网上搜索了几天，寻找一种方法来实现：
1.
使用ManagementObjectSearcher("SELECT * from Win32_Printer")
但只安装了 localy 打印选项

2。

尝试了以下代码-但我不知道服务器或打印机的名称
（我可能知道用户在其中运行我的应用的网络名称-但它可以是任何类型的打印机...）

using (ManagementClass win32Printer = new ManagementClass("Win32_Printer"))
{
    using (ManagementBaseObject inputParam = win32Printer.GetMethodParameters("AddPrinterConnection"))
    {
        // Replace <server_name> and <printer_name> with the actual server and
        // printer names.
        inputParam.SetPropertyValue("Name", "\\\\<server_name>\\<printer_name>");

        using (ManagementBaseObject result =
            (ManagementBaseObject)win32Printer.InvokeMethod("AddPrinterConnection", inputParam, null))
        {
            uint errorCode = (uint)result.Properties["returnValue"].Value;

            switch (errorCode)
            {
                case 0:
                    Console.Out.WriteLine("Successfully connected printer.");
                    break;
                case 5:
                    Console.Out.WriteLine("Access Denied.");
                    break;
                case 123:
                    Console.Out.WriteLine("The filename, directory name, or volume label syntax is incorrect.");
                    break;
                case 1801:
                    Console.Out.WriteLine("Invalid Printer Name.");
                    break;
                case 1930:
                    Console.Out.WriteLine("Incompatible Printer Driver.");
                    break;
                case 3019:
                    Console.Out.WriteLine("The specified printer driver was not found on the system and needs to be downloaded.");
                    break;
            }
        }
    }
}

（从Windows add printers & scanners安装打印机驱动器后，我获得了打印机的 mac地址，即使卸载后我也可以获得它的 IP -地址（建议here）

以上都不对我有帮助...

因此，我正在寻找以编程方式安装新打印机的任何可能方式，例如：

使用“添加新打印机”选项启动PrintDialog
使用windows settings屏幕打开printers & scanners窗口
发现：Process.Start("ms-settings:printers");
使用以上任何数据安装新打印机
以其他任何方式执行....... :)

另一件事-@SajithSageer在上述评论（based on this link）中建议：

我删除了我的2台网络打印机中的1台，1台HP和1台Cannon，它们都在我的WiFi网络上找到并从那里安装，结果是：
1.它们都不是“共享的”-它们始终是“本地的”
2.连接大炮时-它也出现在“ EnableBidi”上
3. EnumeratedPrintQueueTypes = 512不存在-但是会给出结果:)

下面是代码：

for (int i = 0; i < 20; i++) { EnumeratedPrintQueueTypes[] enumerationFlags = { (EnumeratedPrintQueueTypes)Math.Pow(2,i)}; LocalPrintServer printServer = new LocalPrintServer(); //Use the enumerationFlags to filter out unwanted print queues PrintQueueCollection printQueuesOnLocalServer = printServer.GetPrintQueues(enumerationFlags); Console.WriteLine("These are your shared, local print queues:\t {0}\n---------------------------\n", enumerationFlags[0]); foreach (PrintQueue printer in printQueuesOnLocalServer) { Console.WriteLine("\t" + printer.Name ); } Console.WriteLine(); }

结果如下：

如何在同一WiFi网络上查找和安装打印机？
