Hi KK,
You could just set the print area to contain only your data. (Select
your data range, File menu, Print Area, Set Print Area)
One possible reason for your problem is that there is a rogue entry in
a cell which is a long way away from your data. If the columns to the
right of your data are supposed to be blank, select hundreds of them,
then right click, Delete. This will get rid of unwanted data.
Dave.
