<samba:parameter name="lpq cache time"
context="G"
developer="1"
xmlns:samba="http://samba.org/common">
<listitem>
<para>This controls how long lpq info will be cached
for to prevent the <command moreinfo="none">lpq</command> command being called too
often. A separate cache is kept for each variation of the <command moreinfo="none">
lpq</command> command used by the system, so if you use different
<command moreinfo="none">lpq</command> commands for different users then they won't
share cache information.</para>
<para>The cache files are stored in <filename moreinfo="none">/tmp/lpq.xxxx</filename>
where xxxx is a hash of the <command moreinfo="none">lpq</command> command in use.</para>
<para>The default is 10 seconds, meaning that the cached results
of a previous identical <command moreinfo="none">lpq</command> command will be used
if the cached data is less than 10 seconds old. A large value may
be advisable if your <command moreinfo="none">lpq</command> command is very slow.</para>
<para>A value of 0 will disable caching completely.</para>
<para>See also the <link linkend="PRINTING"><parameter moreinfo="none">printing</parameter></link> parameter.</para>
<para>Default: <command moreinfo="none">lpq cache time = 10</command></para>
<para>Example: <command moreinfo="none">lpq cache time = 30</command></para>
