set default paper size in firefox?

[Matt Price <matt.price@utoronto.ca>]

Hi,

the default paper size seems to be set to "A4" in my version of
firefox (0.9.3).  Anyone know how to change that setting?  I often
forget to reset the print option and end up with slightly-wrong page
lengths...  

I have tried messing with "prefs.js" but haven'th ad any luck.  
e.g. I have this in my prefs.js, which I wouldh ave thought would
work:  

user_pref("print.printer_PostScript/default.print_command", "lpr -o number-up=1 ${MOZ_PRINTER_NAME:+'-P'}${MOZ_PRINTER_NAME}"); 
user_pref("print.printer_PostScript/default.print_edge_bottom", 4); 
user_pref("print.printer_PostScript/default.print_edge_left", 4); 
user_pref("print.printer_PostScript/default.print_edge_right", 4); 
user_pref("print.printer_PostScript/default.print_edge_top", 4); 
user_pref("print.printer_PostScript/default.print_in_color", false); 
user_pref("print.printer_PostScript/default.print_paper_height", " 10.98"); 
user_pref("print.printer_PostScript/default.print_paper_name", "Letter"); 
user_pref("print.printer_PostScript/default.print_paper_size_type", 1); 
user_pref("print.printer_PostScript/default.print_paper_size_unit", 0); 
user_pref("print.printer_PostScript/default.print_paper_width", "  8.46"); 
user_pref("print.printer_gimp@:64.print_command", "lpr ${MOZ_PRINTER_NAME:+'-P'}${MOZ_PRINTER_NAME}"); 
user_pref("print.printer_gimp@:64.print_edge_bottom", 4); 
user_pref("print.printer_gimp@:64.print_edge_left", 4); 
user_pref("print.printer_gimp@:64.print_edge_right", 4); 
user_pref("print.printer_gimp@:64.print_edge_top", 4); 
user_pref("print.printer_gimp@:64.print_in_color", true); 
user_pref("print.printer_gimp@:64.print_paper_height", "279.00"); 
user_pref("print.printer_gimp@:64.print_paper_name", "na-letter"); 
user_pref("print.printer_gimp@:64.print_paper_size_type", 1); 
user_pref("print.printer_gimp@:64.print_paper_size_unit", 1); 
user_pref("print.printer_gimp@:64.print_paper_width", "215.00"); 


anyway, appreciate the help.
