Excel 2007 : Printing sheets with page numbers in footer

I am using Excel 2007 and Windows Xp Pro.
I am going crazy trying to figure out why my page numbers don't print on my color Epson R800. They do print on my black and white printer though.
The numbers show up in Preview mode but will not print. I even tryed an empty page - still won't print
I am competely lost in this and need the page numbers on the project that I am doing.
I tried to have the page numbers on the header and that seems to work, but no way can I get them to print on the footer.
Any help would be greatly appreciated
Thank you

If BW printer works and Color doesn't - it sounds like your printable area on that printer is smaller - try either changing the bottm margin and footer location to give more space on the page - or there might be a properties option in your print options for that specific printer (file-print-properties (next to the printer name)
