Can I remove old printer drivers to save space on my Mac?
Short answer: Yes — remove unused printers in System Settings → Printers & Scanners, then delete the maker's folder in /Library/Printers or run its uninstaller. macOS re-downloads drivers when needed.
Yes. First remove printers you no longer use in System Settings → Printers & Scanners (select the printer and click the minus button). Then, if a manufacturer installed a large driver package, look in the Printers folder of the top-level Library for that maker's folder and delete it (administrator password needed), or run the maker's own uninstaller.
macOS downloads drivers again automatically if you add a printer later, so this is low-risk. Printer drivers are rarely huge, though — check what uses the most space first.
