-    Unauthorized access to printers allows attackers to print, eavesdrop sensitive documents.
+    Unauthorized access to printers allows attackers to print, eavesdrop on sensitive documents, and potentially execute commands through PJL (Printer Job Language).
+  impact: |
+    Attackers can gain access to sensitive printed documents, manipulate print jobs, and potentially compromise printer security.
+  remediation: |
+    Implement proper network segmentation, disable unnecessary printer services, and ensure printers are not directly accessible from untrusted networks.
