推荐答案

您可以使用ObjectQuery和System.Management来检索网络上的打印机，就像这样

You can use an ObjectQuery using System.Management to retrieve printers on the network, like this

// Use the ObjectQuery to get the list of configured printers
            System.Management.ObjectQuery query =
                new System.Management.ObjectQuery("SELECT * FROM Win32_Printer");
 
            System.Management.ManagementObjectSearcher searcher =
                new System.Management.ManagementObjectSearcher(oquery);
 
            System.Management.ManagementObjectCollection collection = searcher.Get();
 
            foreach (ManagementObject mo in collection)
            {
                System.Management.PropertyDataCollection pdc = mo.Properties;
                foreach (System.Management.PropertyData pd in pdc)
                {
                    if ((bool)mo["Network"])
                    {
                        cmbPrinters.Items.Add(mo[pd.Name]);
                    }
                }
            }
