Hi ....,
Basically could try fit page to width, ikf you fail with other measures
File, Page Setup, Page
[x] Fit to 1 page(s) wide by [leave blank] tall
The two dimensions are independent of one another use either or both
as needed.
Other tricks:
You can change page margins the easiest from Print Preview.
You have a choice of Landscape or Portrait (File, Page Setup, Page)
Reduce the fontsize for a really large name if it only happens in a cell or two.
Reduce the fontsize for an entire column(s)
Turn on "warp text" (format, cells, alignment, wrap text) and reduce width
of a column. You will end up with some cells having more than one line.
If you can't fit on a page you should know about file, Page Setup, Sheet
Rows to repeat at top i.e. $1:$1 or $1:$2
Columns to repeat at left i.e. $A:$A.
