c# - 获取共享打印机的打印队列详细信息

Question

我正在尝试在共享打印机上打印文档；我需要获取打印队列详细信息。以下代码始终从“Microsoft XPS 文档”获取队列，因为作业数 = 0。但我的默认打印机配置为“HP LaserJet P1505n”

LocalPrintServer server = new LocalPrintServer()
PrintQueueCollection queueCollection = server.GetPrintQueues();
PrintQueue printQueue = null;
foreach (PrintQueue pq in queueCollection)
{
 Logger.LogInfo("PrintQueue1", "Printer1 Queue Name " + pq.FullName);
 printQueue = pq;
 numberOfJobs = printQueue.NumberOfJobs;
 Logger.LogInfo("numberOfJobs1"+ numberOfJobs);
}

如何从该特定共享打印机获取打印队列详细信息？我也尝试过

PrintServer server = new PrintServer(@"\\192.168.100.168\HP LaserJet P1505n");

但出现错误：

Win32 错误：文件名、目录名或卷标语法不正确

我在这里想念什么？

如何从该特定共享打印机获取打印队列详细信息？

尝试这样的事情：

// string.Empty or null for local printers
string printServerName = @"\\server";
string printQueueName= "printer";

PrintServer ps = string.IsNullOrEmpty(printServerName)
    // for local printers
    ? new PrintServer()
    // for shared printers
    : new PrintServer(printServerName);
PrintQueue pq = ps.GetPrintQueue(printQueueName);

Console.WriteLine(pq.FullName);
Console.WriteLine(pq.NumberOfJobs);
// output is printer uri (\\server\printer) and 0.

也可以使用服务器 IP 地址（如字符串）代替服务器名称。

string printServerName = @"\\192.168.1.111"; // for example

即
用于本地打印机 PDFCreator 集

string printServerName = null;
string printerName = "PDFCreator";

并且对于服务器 S 集上的共享打印机 P

string printServerName = @"\\S";
string printerName = "P";

MSDN 上的System.Printing.PrintServer类文档

试试这个：

var myServer = @"\\192.168.100.168";

使用此代码：

// Create a PrintServer
// "theServer" must be a print server to which the user has full print access.
// var myServer = @"\\theServer"
PrintServer myPrintServer = new PrintServer(myServer);

// List the print server's queues
PrintQueueCollection myPrintQueues = myPrintServer.GetPrintQueues();
String printQueueNames = "My Print Queues:\n\n";
foreach (PrintQueue pq in myPrintQueues)
{
    printQueueNames += "\t" + pq.Name + "\n";
}
Console.WriteLine(printQueueNames);
Console.WriteLine("\nPress Return to continue.");
Console.ReadLine();
