cupsd-helper(8) OpenPrinting cupsd-helper(8) NAME cupsd-helper - cupsd helper programs (deprecated) SYNOPSIS cups-deviced request-id limit user-id options cups-driverd cat ppd-name cups-driverd list request_id limit options cups-exec sandbox-profile [ -g group-id ] [ -n nice-value ] [ -u user-id ] /path/to/program argv0 ... argvN DESCRIPTION The cupsd-helper programs perform long-running operations on behalf of the scheduler, cupsd(8). The cups-deviced helper program runs each CUPS back- end(7) with no arguments in order to discover the available printers. The cups-driverd helper program lists all available printer drivers, a sub- set 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. 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 com- pressed 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).
