As much as I like Perl, if you are using Perl to repurpose your data for a printer, then your underlying design is broken. Though Perl can easily do this and there are plenty of suggestions here, you shouldn't have to do this in the first place.

Have a look at the EXCELLENT A List Apart web site, where they show you how to build a very complex visual display simply, and that prints without any complex reparsing.

Properly written XHTML with modern CSS, provides aural cues too. So unless you have legacy HTML, then I would not use Perl to repurpose content.
