DESCRIPTION
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 OS X these programs are run in a secure sandbox.
FILES
The cups-driverd program looks for PPD and driver information files in the following directories:
/Library/Printers
/opt/share/ppd
/System/Library/Printers
/usr/local/share/ppd
/usr/share/cups/drv
/usr/share/cups/model
/usr/share/ppd
PPD files can be compressed using the gzip(1) program or placed in compressed tar(1) archives to further reduce their size.
Driver information files must conform to the format defined in ppdcfile(5).
