<h4 class="subsection">7.2.3 Fonts for Printing</h4>
<a name="index-Fonts-for-printing"></a>

<a name="index-fonttextsize"></a>
<a name="index-Font-size_002c-reducing"></a>
<a name="index-Reducing-font-size"></a>
<a name="index-Smaller-fonts"></a>
<p>Texinfo provides one command to change the size of the main body font
in the TeX output for a document: <code>@fonttextsize</code>.  It has no
effect in other output.  It takes a single argument on the remainder
of the line, which must be either &lsquo;<samp>10</samp>&rsquo; or &lsquo;<samp>11</samp>&rsquo;.  For
example:
</p>
<div class="example">
<pre class="example">@fonttextsize 10
</pre></div>

<a name="index-Printing-cost_002c-reducing"></a>
<p>The effect is to reduce the body font to a 10pt size (the
default is 11pt).  Fonts for other elements, such as sections
and chapters, are reduced accordingly.  This should only be used in
conjunction with <code>@smallbook</code> (see <a href="_0040smallbook.html#g_t_0040smallbook"><code>@smallbook</code></a>) or
similar, since 10pt fonts on standard paper (8.5x11 or A4) are
too small.  One reason to use this command is to save pages, and hence
printing cost, for physical books.
</p>
<p>Texinfo does not at present have commands to switch the font family
to use, or more general size-changing commands.
</p>
<p>Texinfo also provides a number of font commands that specify font
changes in the printed manual and (where possible) in the HTML output.
They have no effect in Info.  All the commands apply to a following
argument surrounded by braces.
</p>
<dl compact="compact">
<dt><code>@b</code></dt>
<dd><a name="index-b-_0028bold-font_0029"></a>
<a name="index-Bold-font"></a>
<p>selects <b>bold</b> face;
</p>
</dd>
<dt><code>@i</code></dt>
<dd><a name="index-i-_0028italic-font_0029"></a>
<a name="index-Italic-font"></a>
<p>selects an <i>italic</i> font;
</p>
</dd>
<dt><code>@r</code></dt>
<dd><a name="index-r-_0028roman-font_0029"></a>
<a name="index-Roman-font"></a>
<a name="index-Default-font"></a>
<p>selects a <span class="roman">roman</span> font, which is the usual font in which text is
printed.  It may or may not be seriffed.
</p>
</dd>
<dt><code>@sansserif</code></dt>
<dd><a name="index-sansserif-_0028sans-serif-font_0029"></a>
<a name="index-Sans-serif-font"></a>
<p>selects a <span class="sansserif">sans serif</span> font;
</p>
</dd>
<dt><code>@slanted</code></dt>
<dd><a name="index-slanted-_0028slanted-font_0029"></a>
<a name="index-Slanted-font"></a>
<a name="index-Oblique-font"></a>
<p>selects a <i>slanted</i> font;
</p>
</dd>
<dt><code>@t</code></dt>
<dd><a name="index-t-_0028typewriter-font_0029"></a>
<a name="index-Monospace-font"></a>
<a name="index-Fixed_002dwidth-font"></a>
<a name="index-Typewriter-font"></a>
<p>selects the <tt>fixed-width</tt>, typewriter-style font used by <code>@code</code>;
</p>
</dd>
</dl>

<p>(The commands with longer names were invented much later than the
others, at which time it did not seem desirable to use very short
names for such infrequently needed features.)
</p>
<a name="index-_003clineannotation_003e-Docbook-tag"></a>
<p>The <code>@r</code> command can be useful in example-like environments, to
write comments in the standard roman font instead of the fixed-width
font.  This looks better in printed output, and produces a
<code>&lt;lineannotation&gt;</code> tag in Docbook output.
</p>
<p>For example,
</p>
<div class="example">
<pre class="example">@lisp
(+ 2 2)    ; @r{Add two plus two.}
@end lisp
</pre></div>

<p>produces
</p>
<div class="lisp">
<pre class="lisp">(+ 2 2)    ; <span class="roman">Add two plus two.</span>
</pre></div>

<p>The <code>@t</code> command can occasionally be useful to produce output in
a typewriter font where that is supported (e.g., HTML and PDF), but no
distinction is needed in Info or plain text: <code>@t{foo}</code>
produces <tt>foo</tt>, cf. <code>@code{foo}</code> producing <code>foo</code>.
</p>
<p>In general, the other font commands are unlikely to be useful; they
exist primarily to make it possible to document the functionality of
specific font effects, such as in TeX and related packages.
