How are you sending it? As an attachment? Or as email content? If the
latter, then a lot would depend on how the recipients choose to view email.
For example, I receive many emails containing formatting, but I never see
that formatting, because I choose to view all incoming email as plain text.
On the other hand, if you're attaching a Word document, then the recipient
should see what you see... with a few caveats. The most important aviate,
with respect to printing, is that the recipient probably doesn't have the
same printer you have. What might work fine for you, given your default
printer, might not work or look the same on your correspondent's printer.
Laser versus inkjet printer differences make a big difference, since the
non-printable area on the former often is larger than that on the former.
When I send something to someone else, and maintaining the same printed
version is important, I'll send it as a pdf. If that's not possible for some
reason, you could at the very least lie to your computer and set up the same
printer your recipient uses. Even that, however, is not guarantee, as you
might be using a different operating system and/or a different version of
the printer driver.
