I'm not sure if PHP is what I should be using for this, and I'm not even sure if the code will even be in use in the final version of the page, but:
Is it possible to create a printer-friendly version of a page via PHP? For example, at the bottom of most article-based sites, there's a link to a "Printer-Friendly Version" that removes backgrounds, non-essential images, what have you, and only leaves the content, easily printable.
Again, I'm not even certain if PHP is the right tool for this job, but I've just started coding in PHP and, frankly, I'm like a giddy child: I really enjoy this language! 🆒
