Secure print is the best option to address the concern of printing confidential documents on a shared enterprise multifunction printer (MFP). Secure print requires users to enter a PIN or use an ID card at the printer to release their print jobs. This ensures that documents are only printed when the user is physically present to collect them, preventing sensitive information from being left unattended or viewed by unauthorized individuals. While a central printer server, audit logs, and Wi-Fi direct printing have their own benefits, they do not provide the same level of immediate security for confidential documents as secure print does. A central printer server centralizes management but does not prevent unauthorized viewing. Audit logs provide a record of activity but do not prevent the initial security breach. Wi-Fi direct printing allows for a direct connection to the printer but does not secure the document during printing.
