@saggitarius You can make restricted printing of PDF files by using the Adobe Experience Manager - Forms Server (Document Security) feature. This feature allows you to create and apply security policies to PDF documents that control the access and usage rights of the recipients. You can set passwords, encryption, and permissions for printing, editing, copying, and more.
One of the ways to restrict the printing of PDF files is to use the Rights Management service, which lets you create dynamic policies that can be updated or revoked at any time. You can also use external authorization to implement custom logic for granting or denying permissions based on certain conditions. For example, you can limit the number of times a PDF file can be printed, or prevent it from being opened or printed after a certain date.
To use the Rights Management service, you need to connect to the Adobe Experience Manager - Forms Server (Document Security) and create a security policy that specifies the printing permission. You can then apply the policy to your PDF files and distribute them to the recipients. The recipients will need to authenticate themselves to open the PDF files and use the allowed features.
To use the external authorization, you need to create a Java class that implements the ExternalAuthorization interface and register it as an OSGi service. You also need to create a security policy that references the external authorization class. You can then apply the policy to your PDF files and distribute them to the recipients. The external authorization class will be invoked whenever a recipient tries to perform an action on the PDF file, and it will return a boolean value to allow or deny the action.
