Last week, Lelldorin (whom I'm sure you know) e-mailed me about a small tutorial he wrote over at BeSly on printing from Firefox, sort of. He uses an experimental FF add-on called "html2pdf" which allows the user to save the page (or according to him, parts of it) as PDF, which can later be printed without a problem.

It's a clever workaround so head over, follow his instructions and see if it works for you as well. Thanks lelldoring and I apologize for not publishing this sooner.
