How do I troubleshoot the Print Spooler service if it's causing the 'Printing in Queue' error?

Open the Services panel (search for 'Services' in Windows). Locate 'Print Spooler,' right-click it, and select 'Restart.' If it's not running, select 'Start.' Check the 'Startup type' property to ensure it's set to 'Automatic.' If problems persist, try clearing the Print Spooler folder (C:\Windows\System32\spool\PRINTERS) – you may need administrator privileges.
