Hi @성진임19409707 ,
Adobe Experience Manager (AEM) Document Security provides robust control over PDF document permissions, including printing. Let's address your questions related to the security features in AEM:
1. Changing Printing Settings After a Certain Period
Question: Can the printing settings be changed to 'Allowed' after a certain period?
Answer: Yes, the printing settings can be changed to 'Allowed' after a certain period. This can be achieved through the configuration of document policies within AEM Document Security. Administrators can define policies that apply specific permissions to documents, including time-based changes. For example, an administrator could set a policy where printing is not allowed initially but becomes allowed after a specified period. This requires setting up an appropriate policy within AEM's Rights Management feature.
2. Offline Lease and Printing Settings
Question: Does the 'Offline Lease 1 day' setting allow the printing settings to change from 'Not Allowed' to 'Allowed'?
Answer: The 'Offline Lease' setting in AEM Document Security specifies the duration a document can be accessed offline without needing to reconnect to the server for reauthorization. This setting itself does not directly change the printing permissions. However, it can be part of a broader policy where permissions, including printing, might change upon reauthorization. For example, after the offline lease period expires and the document is reauthorized, a new policy could potentially change the printing permission to 'Allowed' if configured by the administrator.
3. Situations Leading to Printing Becoming Allowed
Question: In what situations could a PDF file that was not allowed to be printed become printable? (Changes in security settings by an AEM administrator, user error, etc.)
Answer: Several scenarios could lead to a PDF file that initially had printing disabled becoming printable:
- Policy Updates by an Administrator: An AEM administrator could modify the document security policy to allow printing. This change would apply to all documents governed by that policy.
- Policy Expiration or Change: If a document was protected under a policy with a time-based restriction, once the restriction period ends, the document could automatically adopt new permissions that allow printing.
- Reauthorization After Offline Lease: As mentioned earlier, after an offline lease expires and the document reconnects for reauthorization, it might receive updated permissions based on current policy configurations.
- User Error: Although less likely, if permissions are manually overridden by an administrator or due to a misconfiguration, printing might inadvertently become allowed.
- Document Versioning: If a new version of the document is released with different security settings, this new version could have different permissions, including allowing printing.
- Policy Synchronization Issues: In some cases, synchronization issues between the document security policy server and the client application might temporarily result in different permissions being applied.
AEM Document Security offers granular control over document permissions, including time-based permission changes and reauthorization mechanisms. While the 'Offline Lease' setting itself does not change printing permissions directly, it plays a role in the broader context of reauthorization and policy enforcement. Changes in security settings by an AEM administrator or specific policy configurations are the primary means by which a document's printing permissions might change.
