## CloseHandle 확인 필요.

The issue mentions zombie processes and CloseHandle, likely in a Windows/.NET context related to printer management. Look for process or handle management code in the codebase, particularly around printer spooler interactions. Check for resource cleanup in classes that use native handles or spawn processes. Running the application and monitoring for handle leaks with a tool like Process Explorer could show where handles are not being closed.
