Hello Wilson Y,
I am following up to check if you have successfully cleared the "ghost" instance of HQ-COPY02 from your Settings menu. As previously analyzed, this discrepancy between the modern Settings app and the legacy Print Management console confirms that the printer object exists only as a stale registry pointer within the Client Side Rendering Print Provider cache, rather than as a functional queue in the Spooler service. Executing the removal via PowerShell or manually deleting the corrupted keys under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Print\Providers while the Spooler is stopped remains the definitive fix for this specific synchronization error.
If the issue has been successfully resolved, please consider accepting the answer as it helps other people sharing the same question benefit too. Thank you!
