<p>I'll summarize the options. Two solutions are offered in <a href="https://meta.stackexchange.com/q/128703/259867">Can I print a single answer?</a>: </p>

<ol>
<li>Userscript <a href="https://stackapps.com/questions/3307/print-this-post">Print this Post</a> by Manishearth which suppresses everything on the page except the selected posts. </li>
<li><a href="http://www.stackprinter.com/" rel="nofollow noreferrer">StackPrinter</a>, which prints all posts on the page (optionally, suppressing comments). </li>
</ol>

<p>One more solution (mine) is <a href="https://dl.dropboxusercontent.com/u/29863189/mse/savetex.html" rel="nofollow noreferrer">Save Q&amp;A as LaTeX</a>, which converts both the question and its answers to LaTeX. One can delete the question and unwanted answers before printing, although the question is useful for context. </p>

<p>For illustration, I used <a href="https://stats.stackexchange.com/questions/137544/dummy-variables-to-control-clustered-sample">Dummy variables to control for clustering</a> and copy-pasted LaTeX output into <a href="https://www.overleaf.com/" rel="nofollow noreferrer">Overleaf</a>, obtaining <a href="https://dl.dropboxusercontent.com/u/29863189/mse/dummy-variables-control.pdf" rel="nofollow noreferrer">this PDF</a>. </p>
