I send out reports from MS Access in Snapshot format
through Outlook. Almost everyone in the department can
open them and print them with the results identical to the
report I saw in access. There are a few folks that pull
up the reports and their computer always defaults the
orientation of the reports to either portrait or
landscape. They must change it each time they print a
snapshot item. We have tried reinstalling the viewer and
looked for settings, but can't find any reason for this.

Why do most people see the report in whichever orientation
it was sent, but a handful must tell the viewer which to
use?

Thanks for the help!
