This runs in the Acrobat app - there is no separate API for this task.
'Printing Allowed: None' completely stops any printing of your PDF. No one can print it at all. 'Low (150 dpi)' allows printing, but only at a low quality. This means the printed version will not look as sharp or clear as the original. Choose 'None' for maximum security against physical copies, and 'Low' if you need some printing but want to discourage high-quality reproduction.
Your PDF remains locked because the permission settings are protected by an owner password. This password is required to make any changes to the security settings. It ensures that only authorized people can alter who can print, edit, or copy the document, keeping your restrictions secure.
To allow form filling but prevent other changes, you should set 'Changes Allowed' to permit form filling. This specific setting will let users interact with form fields, enter text, and select options without being able to insert, delete, or rotate pages. Always test your settings to ensure only the intended actions are possible.
'Restrict Permissions' is a feature that lets you control what actions other people can take with your PDF document. This includes limiting printing, editing, and copying. It's important for document security because it helps protect sensitive information from being misused or changed without authorization. By setting an owner password, you ensure that only you or trusted individuals can modify these restrictions, maintaining the integrity and confidentiality of your content.
