Our daily spreadsheet template contains 10 printable pages. Each
page contains 5 rows of header information and 25 rows for data entry.
(In other words, one page equals 30 rows). Users will typically
fill up anywhere between 0-6 pages per day.

Here's my problem:

Whenever a user presses 'Print' (or even Ctrl-P), Excel will automatically
print all 10 pages. This will often waste paper, because what if a user
only fills up 2 pages with data? That means the remaining 8 empty pages
get printed as well.

So, if a user presses 'Print' or Ctrl-P, how can I tell Excel to only print
the
pages that contain data?

Thanks!
