how do I change the default font size when printing from email on my new inspiron 530?

I have just upgraded from a dell dimension 4600 desktop to a new inspiron 530, and am still using my old but wonderful and highly reliable HP laserjet 3330 printer. When I now print from a word document, the font size is just what it is on screen, 12 point. But when I print from the body of an email, it is suddenly reduced to tiny mice type (don't know what size it is, but it's VERY little). Also when I go to print, the Fax icon is highlighted rather than the printer icon and it wants to fax rather than print - can I set this somehow to choose printer as a default all the time unless I manually change it to fax, which I hardly ever do from my computer? Does this make sense to anyone?
