Forcing word to print single sided

I have a word document that has some forms at the end. My printer settings are to print duplex by default, but I need to force these forms to print single sided. I dont want to insert blank pages in the document to force this, as people who print single sided will be annoyed. I am also happy for the first part of the document (before the form) to stay duplex, but would accept if this could not happen.

I really want to start a new section in the document where the section information knows it should be printed single sided.

1. Is this possible to do
2. If so, then how.

Thanks
Andrew
