NAME

6       cupsd-helper - cupsd helper programs (deprecated)

SYNOPSIS

9       cups-deviced request-id limit user-id options
10       cups-driverd cat ppd-name
11       cups-driverd list request_id limit options
12       cups-exec  sandbox-profile [ -g group-id ] [ -n nice-value ] [ -u user-
13       id ] /path/to/program argv0 ...  argvN
14

DESCRIPTION

16       The cupsd-helper programs perform long-running operations on behalf  of
17       the  scheduler,  cupsd(8).   The  cups-deviced helper program runs each
18       CUPS backend(7) with no arguments in order to  discover  the  available
19       printers.
20
21       The  cups-driverd helper program lists all available printer drivers, a
22       subset of "matching" printer drivers, or a copy of  a  specific  driver
23       PPD file.
24
25       The  cups-exec  helper  program  runs backends, filters, and other pro‐
26       grams. On macOS these programs are run in a secure sandbox.
27

FILES

29       The cups-driverd program looks for PPD and driver information files  in
30       the following directories:
31
32           /Library/Printers
33           /opt/share/ppd
34           /System/Library/Printers
35           /usr/local/share/ppd
36           /usr/share/cups/drv
37           /usr/share/cups/model
38           /usr/share/ppd
39
40       PPD files can be compressed using the gzip(1) program or placed in com‐
41       pressed tar(1) archives to further reduce their size.
42
43       Driver information files must conform to the format  defined  in  ppdc‐
44       file(5).
45

NOTES

47       CUPS  printer  drivers, backends, and PPD files are deprecated and will
48       no longer be supported in a future feature release of  CUPS.   Printers
49       that  do  not  support  IPP can be supported using applications such as
50       ippeveprinter(1).
