R – How to automatically print a form when a new item is posted to a list in SharePoint

You could customize the NewForm.aspx (e.g. via SharePoint Designer) for the initial submission case. Obviously, all of the required fields will need to be populated in some fashion.

The EditForm.aspx is the out-of-box page for updating existing list items. You may be able to customize this to meet your update an existing risk assessment case. From the post above it's not entirely clear to me whether this distinction between these pages is fully understood.

In both of these cases, you can add code-behind to the .aspx pages. However, it's usually best to start as simply as possible, keep it as simple as possible and only add complexity as necessary.

Hope this makes sense and helps. Good luck!
