<p>Options used:</p>
<ul>
<li>
<p><tt class="LITERAL">:if</tt>, <tt class=
"LITERAL">cf</tt>, <tt class="LITERAL">df</tt>, <tt
class="LITERAL">gf</tt>, <tt class="LITERAL">nf</tt>, <tt
class="LITERAL">:of</tt>, <tt class="LITERAL">rf</tt>,
<tt class="LITERAL">tf</tt>, <tt class="LITERAL">vf</tt>,
<tt class="LITERAL">X</tt><tt class="LITERAL">f</tt>, <i
class="EMPHASIS">Filter programs</i></p>
</li>
</ul>
<br>
<br>
<p><b class="APPLICATION">LPRng</b> has inherited a set of
so-called `<i class="EMPHASIS">print formats</i>' from its
BSD ancestor. The format was used to specify the type of file
that was being printed. The <b class="APPLICATION">lpd</b>
server used the print format to select the filter for
processing the file. The de<i class="EMPHASIS">f</i>ault
format is <tt class="LITERAL">f</tt>.</p>
<p>The user can specify the format (i.e., the file type) by
giving the appropriate option to <b class=
"APPLICATION">lpr</b>:</p>
<ul>
<li>
<p><tt class="LITERAL">-b</tt> or <tt class=
"LITERAL">-l</tt>: Binary (literal) file. No processing
should be done. The <tt class="LITERAL">l</tt> format is
recorded as the file format.</p>
</li>
<li>
<p><tt class="LITERAL">-c</tt>: cifplot(1) output.</p>
</li>
<li>
<p><tt class="LITERAL">-d</tt>: TeX DVI file.</p>
</li>
<li>
<p><tt class="LITERAL">-g</tt>: Output from the plot(3X)
routines.</p>
</li>
<li>
<p><tt class="LITERAL">-n</tt> or <tt class=
"LITERAL">-t</tt>: (di)troff output.</p>
</li>
<li>
<p><tt class="LITERAL">-p</tt>: Text file that should be
pre-processed by the <tt class="LITERAL">pr</tt> command,
and then by the standard text filter.</p>
</li>
<li>
<p><tt class="LITERAL">-v</tt>: Benson Varian raster
image.</p>
</li>
</ul>
<br>
<br>
<p>Alternatively, one can also use <tt class=
"LITERAL">-Fx</tt>, where <tt class="LITERAL">x</tt> is the
format specifier. (E.g., <tt class="LITERAL">-Fc</tt> instead
of <tt class="LITERAL">-c</tt>.) This last form also allows
you to use other (non-standard) format specifiers.</p>
<p>The filter for format <tt class="LITERAL">X</tt> is the
value for the <tt class="LITERAL">Xf</tt> printcap option,
with some minor exceptions. The following <tt class=
"LITERAL">Xf</tt> options have a pre-defined meaning.</p>
<ul>
<li>
<p><tt class="LITERAL">:if</tt> The <tt class=
"LITERAL">f</tt> format filter, i.e. - for the default
<tt class="LITERAL">f</tt> format. All print jobs are
passed through this one, unless another format is
selected.</p>
</li>
<li>
<p><a name="CF"></a> <tt class="LITERAL">cf</tt> Cifplot
data filter (for <tt class="LITERAL">-c</tt> format).</p>
</li>
<li>
<p><a name="DF"></a> <tt class="LITERAL">df</tt> Filter
for DVI files (<tt class="LITERAL">-d</tt>).</p>
</li>
<li>

<p><a name="NF"></a> <tt class="LITERAL">nf</tt> Ditroff
data filter (<tt class="LITERAL">-n</tt>).</p>
</li>
<li>
<p><tt class="LITERAL">:of</tt> This filter is used for
processing the (optional) banner at the start and/or end
of the print job, and also for the interjob separators.
See <a href="ofdetails.htm">OF Filter</a> for
details.</p>
