Sorry to hear your emails are not printing at a readable size. Just to clarify: this is a problem printing emails you opened in Firefox, using an online email site? This is not a problem in a stand-alone email program like Thunderbird, Windows Live Mail, Office Outlook, etc. Two questions: (1) Is this problem limited to your email site? For example, if you call up Print Preview on this site, does Firefox also behave as though you have a very small paper size on this page? To call up Print Preview, you can use either: * "3-bar" menu button > Print * (menu bar) File > Print Preview Does it make any difference if you adjust the scaling on the Print Preview toolbar? By default, it will be set to Shrink to Fit, but you could experiment with 100% or another fixed size. Any improvement? (2) On the printout, does the message use the full height of the paper, or does the message use only the upper left a corner of the paper, as though Firefox thought your paper was about a quarter of its actual size?
