NAME

cupsd-helper - cupsd helper programs (deprecated)

SYNOPSIS

cups-deviced reques-id limit use-id options
cups-driverd cat pp-name
cups-driverd list request_id limit options
cups-exec sandbo-profile [ -g grou-id ] [ -n nic-value ] [ -u use-id ] /path/to/program argv0 ... argvN

DESCRIPTION

The cupsd-helper programs perform lon-running operations on behalf of the scheduler, cupsd(8). The cup-deviced helper program runs each CUPS backend(7) with no arguments in order to discover the available printers.

The cup-driverd helper program lists all available printer drivers, a subset of "matching" printer drivers, or a copy of a specific driver PPD file.

The cup-exec helper program runs backends, filters, and other programs. On macOS these programs are run in a secure sandbox.

FILES

The cup-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).

NOTES

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).
