How do I fix printer spooler error?

To fix a printer spooler error, press Win + R, type services.msc, and hit Enter. Find Print Spooler, right-click it, and select Stop. Then go to C:\Windows\System32\spool\PRINTERS and delete all files. Return to Services and Start the Print Spooler. Restart your computer. This clears stalled print jobs and resets the spooler.
