The cupsd-helper programs perform long-running operations on behalf of the scheduler, cupsd(8). The cups-deviced helper program runs each CUPS backend(7) with no arguments in order to discover the available printers.
The cups-driverd helper program lists all available printer drivers, a subset of "matching" printer drivers, or a copy of a specific driver PPD file.
The cups-exec helper program runs backends, filters, and other programs. On macOS these programs are run in a secure sandbox.
The cups-driverd program looks for PPD and driver information files in the following directories:
Driver information files must conform to the format defined in ppdcfile(5).
CUPS printer drivers, backends, and PPD files are deprecated and will no longer be supported in a future feature release of CUPS. Printers that do not support IPP can be supported using applications such as ippeveprinter(1).
