<p><b class="APPLICATION">LPRng</b> was designed as a
replacement the BSD printing system. As such, it inherited
its command names and options from the latter. As you might
know, SystemV uses a totally different set of commands,
incompatible with the BSD ones.</p>
<p>The good news is that the <b class="APPLICATION">LPRng</b>
binaries include an emulation for the SystemV commands. (See
<a href="lpsimulation.htm">lp Simulation</a> for details.
Briefly, you create links to the appropriate programs, and
invoke them by the link names. <span class="emphasis"><i
class="EMPHASIS">Actually, these links are installed by
default in recent versions.</i></span></p>
<div class="INFORMALEXAMPLE">
<a name="AEN10947"></a>
<pre class="SCREEN">
ln -s lpr lp
ln -s lpq lpstat
ln -s lprm cancel
</pre>
</div>
<br>
<br>
<p>If you make these links, calling <var class=
"LITERAL">lp</var>, <var class="LITERAL">lpstat</var> and
<var class="LITERAL">cancel</var> will give you a (partial)
SVR4 emulation. They have their own man pages, which you
should read if you need the emulation.</p>
<p>Since it is a <span class="emphasis"><i class=
"EMPHASIS">partial</i></span> emulation, you shouldn't expect
everything to work. In particular, I would guess that any
script which relies on the output format of one of your
system binaries will break. Again, see <a href=
"lpsimulation.htm">lp Simulation</a> for more details or
additional suggestions.</p>
