cupsd-helper - cupsd helper programs (deprecated)

# [SYNOPSIS](#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](#DESCRIPTION)

The **cupsd-helper** programs perform long-running operations on behalf of the scheduler, [**cupsd**(8)](/man/os/cups/cupsd.8). The **cups-deviced** helper program runs each CUPS [**backend**(7)](/man/os/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 macOS these programs are run in a secure sandbox.

# [FILES](#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)](/man/os/cups/gzip.1) program or placed in compressed [**tar**(1)](/man/os/cups/tar.1) archives to further reduce their size.

Driver information files must conform to the format defined in [**ppdcfile**(5)](/man/os/cups/ppdcfile.5).

# [NOTES](#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)](/man/os/cups/ippeveprinter.1).
