That happened to me too.
• Turn the printer off/on.
• Disconnect then reconnect the USB connection while the printer is ON.
• Delete the HP LaserJet 6L from Device Manager, then rescan for hardware changes to have Windows re-identify and refresh the drivers.
• Delete the printer from Device Manager and try adding it and configuring it manually choosing the port it's on and other options.
