print_run_command() uses lp_print_command() which internally performs basic substition by calling talloc_sub_basic(). As a result. any of the variables in the "basic set", including "%J" are already substituted. To prevent the unwanted subtitution, we declare all affected configuration options as const, which disabled the basic substition. As a result print_run_command() can run manual substitution on all characters, including %J, in the variadic argument list *before* calling lp_string() to run basic substition which we had disabled before with the const.

<para>This parameter specifies the command to be
|
|
executed on the server host in order to delete a print job.</para>
|
|
|
|
<para>This command should be a program or script which takes
|
|
a printer name and job number, and deletes the print job.</para>
|
|
|
|
<para>If a <parameter moreinfo="none">%p</parameter> is given then the printer name
|
|
is put in its place. A <parameter moreinfo="none">%j</parameter> is replaced with
|
|
the job number (an integer).</para>
|
|
|
|
<para>Note that it is good practice to include the absolute
|
|
path in the <parameter moreinfo="none">lprm command</parameter> as the PATH may not be

available to the server.</para>

Examples of use are:

|
<programlisting>
|
|
lprm command = /usr/bin/lprm -P%p %j

or
|
|
|
|
lprm command = /usr/bin/cancel %p-%j
