How to control All print jobs on a PrintServer using PrintServer class and PrintQueue class

I'm new to C# and I have been assigned to control print jobs (pause, authenticate, resume ) on a print server that has almost 50 IP printers connected to it.

Now, I can pause and access details of print jobs of a particular printer on my development PC using printServer class at run time, like:

PrintServer myprintServer = new PrintServer();

foreach (var job in myprintServer.GetPrintQueue("printerA").GetPrintJobInfoCollection()) 

job.pause();

While my program is running and print job comes for lets say printerB or printerC they dont get controlled. I would have to run separate loops for all which is not possible.

Is there any way to control and pause all print jobs whether they come for printerA, b, c etc which are received on a print server and check for authentication. Either I havent found needed methods in System.Printing namespace or task cant be achieved.

GetPrintQueues should return a collection of all print queues on a printer:

PrintServer myprintServer = new PrintServer();

foreach (var queue in myprintServer.GetPrintQueues)
    foreach (var job in queue.GetPrintJobInfoCollection()) 
        job.pause();

Note that there's an overload that takes a list of valid print queue types

Or use SelectMany from Linq:

    foreach (var job in queue.GetPrintQueues.SelectMany(q => GetPrintJobInfoCollection()) 
        job.pause();
