Vista fax - Margins do not fit page size.

Hi,

Using Vista Business and Excel 2003 (have tried excel 2007, no difference).

When trying to fax an Excel sheet (it's 10 cells wide by 10 down) I go to
print setup and change to "fit to 1 page wide/tall", change to the MS fax
device, then do a print preview.
I get an error message saying "Margins do not fit page size", then the
preview appears showing there are 100 pages to print/fax. (1 page per cell
I guess).

I can then manually adjust the margins to make it fit, but don't think I
should have to. (never had to in XP fax).

Has anyone else seen this and/or found a solution?

Thanks.
