<H2>DESCRIPTION</H2>
|
|
|
|
The <B>cupsd-helper</B> programs perform long-running operations on behalf of the scheduler,
|
|
<B><A HREF="/cgi-bin/man/man2html?8+cupsd">cupsd</A></B>(8).
|
|
|
|
The <B>cups-deviced</B> helper program runs each CUPS
|
|
<B><A HREF="/cgi-bin/man/man2html?7+backend">backend</A></B>(7)
|
|
|
|
with no arguments in order to discover the available printers.
|
|
<P>
|
|
|
|
The <B>cups-driverd</B> helper program lists all available printer drivers, a subset of "matching" printer drivers, or a copy of a specific driver PPD file.
|
|
<P>
|
|
|
|
The <B>cups-exec</B> helper program runs backends, filters, and other programs. On macOS these programs are run in a secure sandbox.

|
<H2>FILES</H2>
|
|
|
|
The <B>cups-driverd</B> program looks for PPD and driver information files in the following directories:
|
|
<PRE>
|
|
|
|
<I>/Library/Printers</I>
|
|
<I>/opt/share/ppd</I>
|
|
<I>/System/Library/Printers</I>
|
|
<I>/usr/local/share/ppd</I>
|
|
<I>/usr/share/cups/drv</I>
|
|
<I>/usr/share/cups/model</I>
|
|
<I>/usr/share/ppd</I>
|
|
</PRE>
|
|
|
|
<P>
|
|
|
|
PPD files can be compressed using the
|
|
<B><A HREF="/cgi-bin/man/man2html?1+gzip">gzip</A></B>(1)
|
|
|
|
program or placed in compressed
|
|
<B><A HREF="/cgi-bin/man/man2html?1+tar">tar</A></B>(1)
|
|
|
|
archives to further reduce their size.
|
|
<P>
|
|
|
|
Driver information files must conform to the format defined in
|
|
<B><A HREF="/cgi-bin/man/man2html?5+ppdcfile">ppdcfile</A></B>(5).

|
|
|
<A NAME="lbAF"> </A>

<H2>NOTES</H2>
|
|
|
|
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
|
|
<B><A HREF="/cgi-bin/man/man2html?1+ippeveprinter">ippeveprinter</A></B>(1).
