Each time I try to print a worksheet, Excel prints it out at about half size.

I have set the page setup to print 1 page tall and 1 page wide but that
doesn't have any effect.

I would like to avoid using zoom since I have about ten workbooks with
slightly different formatting in each and am worried that zoom would produce
inconsistency in printing across workbooks so a solution that avoids using
zoom would be greatly appreciated.

Any thoughts?

I am using Excel 2000 on XP SP2.
