When you create the PDF,

• set an admin password
• set an EMPTY user password
• set printing document permission to false

If you do not create the PDFs or cannot edit them, then you cannot make the document view-only.

You can use the CFPDF tag to set print permissions. Create copies of all your document and batch process them (or cache them as needed).

<cfpdf action="protect" newOwnerPassword="IHaveCoolPasswords" source="cooldocument.pdf" 
    destination="protected_cooldocument.pdf" overwrite="yes" permissions="AllowScreenReaders">
