It seems that someone has changed something so mozilla (4.5 - 3.0.6) comes up by default with the printing option "Ignore Scaling and Shrink to fit page width" on by default - always.
This means that any pdf you save with small type on it ends up with nothing there. (for example, airline tickets!) it's completely fucked up. Please fix it so this option is *not* on by default so you can actually save things as pdfs -Bob
