How can I use the Event Viewer to diagnose the "deleting print queue error processing command"?

The Event Viewer can provide critical diagnostic information. Open Event Viewer (`eventvwr.msc`), navigate to 'Windows Logs' -> 'System' or 'Application', and specifically check 'Applications and Services Logs' -> 'Microsoft' -> 'Windows' -> 'PrintService' -> 'Operational'. Look for error or warning events logged around the time the issue occurred to pinpoint specific service failures or command execution problems related to the print spooler.
