Hi,

My Requirement is to get the Network Printer status from my ASP.NET Application and based on that I need to update the database details for the next process.

In my case, For Network Printer It is always return Empty.I don't think that i am going on the correct way. Anyone please tell me the correct way to achieve this.

Any help would be greatly appreciated.

What I have tried:

My Code is like this

C#

private string GetPrintJobStatus()
        {
            ObjectQuery wmiQuery = null;
            ManagementObjectSearcher objManagementobjectSearcher = null;
            ManagementObjectCollection objManagementObjectCollection = null;

            string Name = ""; // wmi print job is combination of "printerName , job number"
            string[] namesplit = null;
            string l_printerName = "";
            string l_jobNumber = "";
            string l_jobStatus = "";
            string l_status = "";

            string l_ReturnStatus = "";
            try
            {
                wmiQuery = new ObjectQuery("Select * from Win32_PrintJob");
                objManagementobjectSearcher = new ManagementObjectSearcher(wmiQuery);
                objManagementObjectCollection = objManagementobjectSearcher.Get();
                foreach (ManagementObject printJob in objManagementObjectCollection)
                {
                    Name = Convert.ToString(printJob["Name"]);
                    namesplit = Name.Split(',');
                    l_printerName = namesplit[0];
                    l_jobNumber = namesplit[1];
                    if (Convert.ToString(Session["printername"]) != "")
                    {
                        if (l_printerName == Convert.ToString(Session["printername"]))
                        {
                            l_status = Convert.ToString(printJob["Status"]);

                            if (l_status.ToUpper().Equals("OK"))
                            {
                                l_jobStatus = Convert.ToString(printJob["JobStatus"]);

                                switch (l_jobStatus)

Why don't you use a print server and then let it handle this for you? You can then ping the server to know the status.

Tq..PrintServer class in system.printing namespace are not support to use within windows service or ASP.NET Applications.

The account your code runs under by default is very restrictive and has no access to the network so you'll struggle doing these kinds of things. You'll need to run your code under an account that has the desired access you need, google for how to change the account your code runs under, it depends on the version of IIS you are using.

Tq..You are speaking about impersonation.See I can able to print from my application to the network printer by means of impersonation. but my problem is that , I can't get the status from network printer.based on the status only i need to mark printed status in my database. How can I proceed?
