In Chrome, the headers are at 0.33" from the top, the footers are at 
.18" from the bottom, when the margins are moved to their placement on 
the screen.

WRT Firefox: I don't know if this information will help, but in the 
preferences file (aka about:config), print_print_margin_top and 
print_print_margin_bottom both show (as string) 0.5 for the value, but 
if this actually means 1/2" from both top and bottom, the headers and 
footers print closer than that to the top and bottom of the pages. The 
preferences print_print_unwriteable_margin_top and 
print_print_unwriteable_margin_bottom both show (as integer) 13 as the 
value. I'm not finding a setting anywhere to manually change the margins 
in Firefox.
