Printer-friendly version of message window

Hello!

First of all, i would like to thank the developers for this fantastic module. I use it on my site to display the results of an analysis after some batch runs. My question is about a feature integration which is connected to the Print module. (I'm not sure to which module i have to post this issue, i hope someone gives a hint.)

What i want to do is to somehow make the content of the message window to appear in a printer-friendly format (so the user can print it), or to save the content to pdf. So the question boils down to one sentence:
How can i integrate the Print module to the Better Messages window?
Every advise is welcome. Thank u in advance!
