I have sometimes seen people manually copying PPD files as a means of installing printers do not rely on this! Some drivers require only a PPD but others may need support files as well. In that case, the original installer package from the manufacturer should handle re-installation of all relevant files. There is no standard way to remove these because each driver can include support files in different places, but there is no cause to delete them unless you are intending to reinstall the driver. (Technically, when you create a printer queue, a copy of the PPD is created for that printer, which will be deleted when deleting the queue.) The 'Reset printing system.' option will also not remove any drivers it will only delete all configured print queues and reset some CUPs configuration to defaults.ĭeleting a PPD file listed by lpinfo will effectively delete the driver, as it will no longer be loaded by the CUPS system, though as explained above there may be additional support files left behind. If you open the PPD in a text editor you should find a *FileVersion line that lists the driver version.ĭeleting a printer using the 'minus' button in System Preferences does not delete/uninstall the driver, it just deletes the queue that has been created for the printer in question. However, the PPD file is just plaintext (optionally compressed). There doesn't seem to be much consistency regarding version numbers I've seen some vendors include the version in the make-and-model string that's returned by lpinfo -m (Xerox, for example), but it's certainly not universal. As you can see, some drivers are internal to CUPS and do not even have a PPD file in /Library/Printers, so lpinfo -m is the only way to be certain of everything available to the printing system.

CUPS specifies that drivers can consist of an arbitrary number of files, but they must all be declared in a central PPD file. The only authoritative list of available print drivers on OS X is that returned by lpinfo -m (specifying the host is not necessary for the local machine). While drivers are typically found in /Library/Printers, the folder can contain support files and many other things which are not themselves print drivers, and in the real world there is no canonical location within the folder where the actual driver files are stored.

Since Mac OS 10.2, printing is handled by the CUPS system.
