<p>A print job consists of a control file and one or more
data files. <a href="rfc1179.htm">RFC1179</a> specifies the
general format of these files and how they are to be
transfered between servers. <b class="APPLICATION">LPRng</b>
has extended the contents of the control files and the
transfer protocol to provide a more powerful set of features,
but has extensive provisions for backwards compatibility with
non-<b class="APPLICATION">LPRng</b> software. A sample
control file is shown below:</p>
<div class="INFORMALEXAMPLE">
<a name="AEN6467"></a>
<pre class="SCREEN">
Hh4.private
J/tmp/file1 /tmp/file2
CA
Lpapowell
Ppapowell
fdfA002230h4.private
N/tmp/file1
UdfA002230h4.private
fdfB002230h4.private
N/tmp/file2
UdfB002230h4.private
</pre>
</div>
<br>
<br>
<p>The first part of the control file contains general
information generated by the <b class="APPLICATION">lpr</b>
or other spooling program. The information lines start with
an uppercase letter or digit. Some other spooling systems
also start information lines with various punctuation marks
such as underscores (_) or periods (.).</p>
<p>Following this are a set of entries about each of the
various files to be printed. These lines start with a lower
case letter, followed by the print file name. The lower case
letter is the <i class="EMPHASIS">format</i> to be used to
process the file. See <a href="printingjob.htm">print file
formats</a> for more information about its use.</p>

<p>The entries marked with * are used only by <b class=
"APPLICATION">LPRng</b>. <tt class="LITERAL">N</tt> and <tt
class="LITERAL">U</tt> lines are associated with a print
file. The <tt class="LITERAL">N</tt> line is the original
name of the print file. By default, <b class=
"APPLICATION">LPRng</b> places this line <i class=
"EMPHASIS">before</i> the corresponding data file. You can
use the <tt class="LITERAL">nline_after_file</tt> option to
have <b class="APPLICATION">LPRng</b> place the N line after
the data file line. The <tt class="LITERAL">U</tt> line
originally was used to indicate that the named file was to be
unlinked after printing. This information is now ignored by
<b class="APPLICATION">LPRng</b>. These lines are always
grouped with a print file entry.</p>
<p>The names of control and data files follow a very strict
pattern. Control files have the format <tt class=
"LITERAL">cfX</tt><tt class=
"REPLACEABLE"><i>number</i></tt><i class="EMPHASIS">host</i>,
where X is an upper case letter, <i class=
"EMPHASIS">number</i> is (usually) a 3 digit number, and <i
class="EMPHASIS">host</i> is the host name. <a href=
"rfc1179.htm">RFC1179</a> restricted the total length of the
control file name to 32 characters; <b class=
"APPLICATION">LPRng</b> has a much looser limit.</p>
<p>Data file names must follow the same pattern as the
control file name, and have the format <tt class=
"LITERAL">dfX</tt><tt class=
"REPLACEABLE"><i>number</i></tt><i class="EMPHASIS">host</i>.
The X can be in the range A-Za-z, allowing at most 52 data
files for a job. The <i class="EMPHASIS">number</i> and <i
class="EMPHASIS">host</i> must be identical to the
corresponding control file.</p>
<p>By convention, <b class="APPLICATION">LPRng</b> uses the X
of the control file name to set a priority for the job. A job
with control file name <tt class="LITERAL">cfA...</tt> will
have <i class="EMPHASIS">lower</i> format than a job with
format <tt class="LITERAL">cfB...</tt>, and so forth. The <b
class="APPLICATION">lpr</b> program uses the first letter of
the class name or an explicit priority value to set the
letter value. If none of these are specified, then the <tt
class="LITERAL">default_priority</tt> value from the
configuration or printcap entry is used.</p>
<p>The job number is usually a 3 digit value. However, in
systems where a large number of jobs are spooled and need to
be kept for printing at scheduled times, this can lead to
problems. The <tt class="LITERAL">longnumber</tt> option will
use 6 digit job numbers. This must be used with care when
operating with non-<b class="APPLICATION">LPRng</b>
software.</p>
