Has anyone got some pointers to formatting documents so
that they look the same when created on a W98 machine and
opened on an XP machine.

We have Office 2000 STD SP3 on all machines and a doc
created on a 98 machine will open on a XP machine with
the text pushed down the page slightly. Not a problem
with a short single page document, but when there is a
few pages, and text is close to the bottom of the page, a
2 page document opened on a XP machine can turn to 3-4
pages.
Same printers are installed on the machines (granted
different drivers).
There are a variety of docs, some have tables, some
headers/footers etc. All these documents are merged in
some way. ie they have links that grab data from our CRM
database. Sometimes we also see extra header/footer lines
after the merge.

Thanks for any advice/links/pointers in advance.
