How do I get a printer friendly version of the subject document?
Adobe stopped providing printable versions of the user guide several versions ago. However, you can download the most recent PDF version from this link. It will obviously not contain any help with more recent features, but the basics will still be applicable.
You can access the current Online Manual from the Help menu. Also, if you have a specific question, the Search box on the Elements Home Screen can provide useful resources.
FYI, there are some books available that might be helpful. Just search Amazon for "photoshop elements 2023 book"
