Problem one is that Merge output tends to have one section for each record
in the data source, with the same page numbering per section. So for
example, if you say "print page 1" and the mail merge main document is only
one page long, you will get all the pages numbered 1, i.e. all the pages.

So you should probably merge to an output document then specify the pages
using p1s1-p1s10 notation in the print dialog (see Word Help for futher and
doubtless more accurate info.)
