theme CSS overriding PrintFriendly's

I inserted the code inside a class I have on my site, like this:

<div class="my-class"><i class="fa fa-print"></i><?php if(function_exists('pf_show_link')){echo pf_show_link();} ?></div>

The “print” link does not catch my-class original CSS, and the text is not aligned to the icon but below it. How can I force the text to align right of the Fontawesome image?
