The printer driver folder was 0 MB, and the advice is fifteen years old
Deleting /Library/Printers was once worth gigabytes. Measured on current macOS it is empty, and the reason explains where drivers went.
Almost every Mac cleanup list tells you to empty /Library/Printers. It was excellent advice in about 2011, when a single manufacturer's driver bundle ran to several gigabytes and installed every model in the range. On current macOS it is close to pointless.
Where the drivers went
- AirPrint removed the need for a driver for most printers made in the last decade. The printer describes itself and macOS handles the rest.
- Drivers arrive per device. When a printer does need software, macOS fetches only that model's support through Software Update rather than installing a whole catalogue.
- Manufacturer suites are separate. The HP or Canon utilities people remember are applications, and they live in
/Applications, not in the printer folder.
Check yours in one line
du -sh /Library/Printers 2>/dev/null
ls -la /Library/Printers 2>/dev/null
# If anything is there, this is what it is
du -sh /Library/Printers/* 2>/dev/null | sort -h | tailWhen it is not empty
There are two cases worth knowing, and both come from history rather than from today's printers.
| What you find | Where it came from |
|---|---|
/Library/Printers/hp, Canon, Brother, EPSON | A manufacturer installer, usually years old |
| Gigabytes of it | A Mac migrated forward from an older machine |
An app in /Applications instead | The scanning or ink utility, which is a normal application |
A Mac that has been migrated from machine to machine carries this sort of thing for years, which is the argument in what not to migrate to a new Mac. If a folder there is genuinely large, removing the printer in System Settings and then deleting the manufacturer folder is safe, and the printer can be added again afterwards.
The wider point is worth more than the folder: advice about Mac storage ages badly, and a command that measures your machine beats an article that remembers someone else's. That is the whole of the Mac storage myths.
Common questions
Is it safe to delete printer drivers on a Mac?
Yes, and on current macOS there is usually nothing there. Measured on macOS 26.6.2, /Library/Printers was 0 MB. If a manufacturer folder is present, remove the printer in System Settings first, then delete the folder.
Why is my Mac printer folder empty?
Because most printers now use AirPrint, which needs no driver, and any model that does need one has its support fetched individually through Software Update rather than as a full catalogue.
Where do HP and Canon printer apps live on a Mac?
In /Applications, as ordinary applications. The scanning and ink utilities people remember are separate from the driver folder entirely.
Why do cleanup guides still say to delete printer drivers?
Because it was worth gigabytes over a decade ago and the advice was copied forward. Measuring the folder takes one command and settles it.
