Font size is super big under printable area on a ticket in IE7

This was brought it my attention that when you print out a ticket from jira in IE7 that the font is all of a sudden huge. I checked Firefox and it seems to be okay.

Source code for IE7 is :

margin: 0px;
font-size: 12px;
font-family: Arial, Sans-Serif, sans-serif;
color:black;

Source code for Firefox is:

margin: 0px;
font-size: 12px;
font-family: Arial, Sans-Serif, sans-serif;
color:black;

Do you guys know why this font would be so large on IE7 but ok on Firefox?
