how to get printer queue job from network printer?

Question

I have printer in my network to which I get by ip. I use OLEPRNLib library to get it status and it works ok.

I try to get job queue with this but it won't works:

 System.Management.ObjectQuery oq = new System.Management.ObjectQuery("SELECT * FROM Win32_PrintJob");
            ManagementObjectSearcher query1 = new ManagementObjectSearcher(oq);
            ManagementObjectCollection queryCollection1 = query1.Get();
            if (queryCollection1.Count == 0)
            {
                this.listBox1.Items.Add("Nie ma jobów");
            }
                foreach (ManagementObject prntJob in queryCollection1)
            {
              String jobName = prntJob.Properties["Name"].Value.ToString();
            }

How can I get that jobs queue from printer by ip adress?
