<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> </listitem> </samba:parameter>
