c# 示例
using System.Management;
string query = string.Format("SELECT * from Win32_Printer WHERE Name =‘{0}‘ ", printerName);
ManagementObjectSearcher searcher = new ManagementObjectSearcher(query);
ManagementObjectCollection printerzs = searcher.Get();
foreach (ManagementBaseObject printer in printerzs)
{
string printername = printer.Properties["Name"].Value.ToString();
if (printername == printerName)
{
string workOffline = printer.Properties["WorkOffline"].Value.ToString().ToLower();
printerStruct.WorkOffline = workOffline.ToLower() == "true";
string jobCount = printer.Properties["JobCountSinceLastReset"].Value.ToString();
printerStruct.JobCount = Convert.ToInt32(jobCount);
Core.PrinterStatus ret = (Core.PrinterStatus)Convert.ToInt32(printer.Properties["PrinterStatus"].Value);
printerStruct.PrinterStatus = ret;
printerStruct.PrinterStatusString = ret.ToString();
}
