How do I export glossary items (a collection) for printing?

If you publish a Project as a document you can include the Project's glossaries, including settings for including Collection and Global glossary terms. You can see these settings if you choose Custom on the Profile drop down list.

And while you're on the custom settings, you could also de-select all of the other options listed to reduce the amount of content being published to your document besides the glossary. You'll probably still need to do some editing, but this will help reduce that work.

You can then provide this doc (maybe convert it to PDF) as a Resource for the Project so learners can download a copy.
