<h4 class="subsection" id="Intermediate-Output-Examples-1">6.1.3 Intermediate Output Examples</h4>
<p>This section presents the intermediate output generated from the same
input for three different devices. The input is the sentence ‘<samp class="samp">hell
world</samp>’ fed into <code class="code">gtroff</code> on the command line.
</p>
<dl class="table">
<dt>High-resolution device <code class="code">ps</code></dt>
<dd>
<p>This is the standard output of <code class="code">gtroff</code> if no <samp class="option">-T</samp> option is
given.
</p>
<div class="example">
<div class="group"><pre class="example-preformatted">shell> echo "hell world" | groff -Z -T ps
x T ps

</pre><div class="group"><pre class="example-preformatted">x trailer

x stop
</pre></div></div>
<p>This output can be fed into <code class="code">grops</code> to get its representation as a
PostScript file.
</p>
</dd>
<dt>Low-resolution device <code class="code">latin1</code></dt>
<dd>
<p>This is similar to the high-resolution device except that the
positioning is done at a minor scale. Some comments (lines starting
with ‘<samp class="samp">#</samp>’) were added for clarification; they were not generated by
the formatter.
</p>
<div class="example">
<div class="group"><pre class="example-preformatted">shell> echo "hell world" | groff -Z -T latin1

document.

</dd>
<dt><abbr class="acronym">AT&T</abbr> <code class="code">troff</code> output</dt>
<dd><p>Since a computer monitor has a much lower resolution than modern
printers, the intermediate output for X11 devices can use the
jump-and-write command with its 2-digit displacements.
</p>
<div class="example">
<div class="group"><pre class="example-preformatted">shell> echo "hell world" | groff -Z -T X100

x stop
</pre></div></div>
<p>This output can be fed into <code class="code">xditview</code> or <code class="code">gxditview</code> for
displaying in X.
</p>
<p>Due to the obsolete jump-and-write command, the text clusters in the
<abbr class="acronym">AT&T</abbr> <code class="code">troff</code> output are almost unreadable.
