Visual c++ 根据打印机状态获取打印机详细信息
在Visual c++ 根据打印机状态获取打印机详细信息,visual-c++,Visual C++,在VC++中使用Windows Management Instrumentation(WMI),我们可以找到系统名称和其他属性等系统信息 GetComputerName示例: BOOL WINAPI GetComputerName( _Out_ LPTSTR lpBuffer, _Inout_ LPDWORD lpnSize ); 我的系统中连接了3台打印机1台热敏打印机和2台共享打印机 如何获取脱机打印机的相关信息? 如何根据打印机的状态对其进行分类/列出 谢谢另请参见 DWO
