I don't use any printers now, but I have in the past. Systems Preferences / Printers & Scanners shows "No printers are available". However, /Library/Printers still contains over 200Mb of stuff.
How can I clean the contents of /Library/Printers and any other folders that contain printer stuff?
I suppose /Library/Printers protected by SIP and so
sudo rm will not work, nor is recommended.
I'm running El Captain 10.11.6 (15G21013).
