<p>Sequence of Operations:</p>
<ol type="1">
<li>
<p>If we are printing and the <tt class="LITERAL">fq</tt>
flag is set and the <tt class="LITERAL">sf</tt> (suppress
interfile FF) flag is set, then the <tt class=
"LITERAL">ff</tt> (form feed) string will be interpreted
and sent to the of_fd.</p>
</li>
<li>
<p>If we are printing, the <tt class="LITERAL">tr</tt>
(trailer) string will be interpreted and sent to the
of_fd.</p>
</li>
<li>
<p>If printing and the <tt class="LITERAL">la</tt> (local
printer accounting) flag is set or transferring a job and
the <tt class="LITERAL">ar</tt> (remote accounting) flag
is set, the <tt class="LITERAL">ae</tt> is examined and
accounting is done as described for the <i class=
"EMPHASIS"><a href="opendevice.htm#ACCOUNTSTART">as</a>
field.</i></p>
</li>
<li>
<p>If the <tt class="LITERAL">:of</tt> filter is present,
its <span class="ACRONYM">STDIN</span> is closed, and the
<b class="APPLICATION">lpd</b> server waits for it to
exit. The exit status is used as described above.</p>
</li>
<li>
<p>If the device is a socket or network connection, the
socket linger time is set to <tt class=
"LITERAL">socket_linger</tt> value if nonzero.</p>
</li>
<li>
<p>If the <tt class="LITERAL">half_shut</tt> flag is set,
then a <tt class="LITERAL">shutdown(fd,WR_DONE)</tt> will
be done on the connection. This tells the TCP/IP stack
that all data transmission has been completed. Errors or
other information can still be read from the connection.
If the <tt class="LITERAL">half_shut</tt> flag is clear,
then a <tt class="LITERAL">close(fd)</tt> will be done
and no errors or other information will be read.</p>
</li>
<li>
<p>If the <tt class="LITERAL">wait_for_eof</tt> option is
true (default) then a read is done on the connection
until an EOF is found. The device (io_fd) is then
closed.</p>
</li>
<li>
<p>The job is marked as completed in the spool queue.</p>
</li>
<li>
<p>If the <tt class="LITERAL">save_when_done</tt> flag is
clear and the <tt class="LITERAL">done_jobs</tt> and <tt
class="LITERAL">done_jobs_max_age</tt> values are zero
(0), the job is removed.</p>
</li>
<li>
<p>If the <tt class="LITERAL">done_jobs</tt> or <tt
class="LITERAL">done_jobs_max_age</tt> values are
nonzero, the spool queue is periodically checked and for
an excess number of jobs or jobs with old status. This
action is suppressed if either the <tt class=
"LITERAL">save_when_done</tt> or <tt class=
"LITERAL">save_on_error</tt> flag is set.</p>
</li>
