  51 .SH DESCRIPTION
  52 The \fBcupsd\-helper\fR programs perform long-running operations on behalf of the scheduler,
  53 .BR cupsd (8).
  54 The \fBcups-deviced\fR helper program runs each CUPS
  55 .BR backend (7)
  56 with no arguments in order to discover the available printers.
  57 .LP
  58 The \fBcups-driverd\fR helper program lists all available printer drivers, a subset of "matching" printer drivers, or a copy of a specific driver PPD file.
  59 .LP
  60 The \fBcups-exec\fR helper program runs backends, filters, and other programs. On OS X these programs are run in a secure sandbox.
  61 .SH FILES
  62 The \fBcups-driverd\fR program looks for PPD and driver information files in the following directories:
  63 .nf
  64
  65     \fI/Library/Printers\fR
  66     \fI/opt/share/ppd\fR
  67     \fI/System/Library/Printers\fR
  68     \fI/usr/local/share/ppd\fR
  69     \fI/usr/share/cups/drv\fR
  70     \fI/usr/share/cups/model\fR
  71     \fI/usr/share/ppd\fR
  72 .fi
  73 .LP
  74 PPD files can be compressed using the
  75 .BR gzip (1)
  76 program or placed in compressed
  77 .BR tar (1)
  78 archives to further reduce their size.
  79 .LP
  80 Driver information files must conform to the format defined in
  81 .BR ppdcfile (5).
