Specifies whether to purge job history data automatically when it is no longer required for quotas.
The default is "No".
+<dt><a name="BrowseDNSSDSubTypes"></a><b>BrowseDNSSDSubTypes</b><i>_subtype[,...]</i>
+<dd style="margin-left: 5.0em">Specifies a list of Bonjour sub-types to advertise for each shared printer.
+For example, "BrowseDNSSDSubTypes _cups,_print" will tell network clients that both CUPS sharing and IPP Everywhere are supported.
+The default is "_cups" which is necessary for printer sharing to work between systems using CUPS.

<dd style="margin-left: 5.0em"><dt><b>BrowseLocalProtocols none</b>
<dd style="margin-left: 5.0em">Specifies the delay for updating of configuration and state files.
A value of 0 causes the update to happen as soon as possible, typically within a few milliseconds.
The default value is "30".
+<dt><a name="DNSSDHostName"></a><b>DNSSDHostName</b><i>hostname.example.com</i>
+<dd style="margin-left: 5.0em">Specifies the fully-qualified domain name for the server that is used for Bonjour sharing.
+The default is typically the server's ".local" hostname.
<dt><a name="ErrorPolicy"></a><b>ErrorPolicy abort-job</b>
<dd style="margin-left: 5.0em">Specifies that a failed print job should be aborted (discarded) unless otherwise specified for the printer.

-<dd style="margin-left: 5.0em">Sets encryption options.
+<dd style="margin-left: 5.0em">Sets encryption options (only in /etc/cups/client.conf).
By default, CUPS only supports encryption using TLS v1.0 or higher using known secure cipher suites.
-The <i>AllowDH</i> option enables cipher suites using plain Diffie-Hellman key negotiation.
-The <i>AllowRC4</i> option enables the 128-bit RC4 cipher suites, which are required for some older clients that do not implement newer ones.
+Security is reduced when <i>Allow</i> options are used.
+Security is enhanced when <i>Deny</i> options are used.
+The <i>AllowDH</i> option enables cipher suites using plain Diffie-Hellman key negotiation (not supported on systems using GNU TLS).
+The <i>AllowRC4</i> option enables the 128-bit RC4 cipher suites, which are required for some older clients.
The <i>AllowSSL3</i> option enables SSL v3.0, which is required for some older clients that do not support TLS v1.0.
The <i>DenyCBC</i> option disables all CBC cipher suites.
The <i>DenyTLS1.0</i> option disables TLS v1.0 support - this sets the minimum protocol version to TLS v1.1.
+The <i>MinTLS</i> options set the minimum TLS version to support.
+The <i>MaxTLS</i> options set the maximum TLS version to support.
+Not all operating systems support TLS 1.3 at this time.

The default is the empty string, which disables page logging.
The string "%p %u %j %T %P %C %{job-billing} %{job-originating-host-name} %{job-name} %{media} %{sides}" creates a page log with the standard items.
+Use "%{job-impressions-completed}" to insert the number of pages (sides) that were printed, or "%{job-media-sheets-completed}" to insert the number of sheets that were printed.
<dt><a name="RIPCache"></a><b>RIPCache </b><i>size</i>
<dd style="margin-left: 5.0em">Specifies the maximum amount of memory to use when converting documents into bitmaps for a printer.
The default is "128m".
