Enforce HTTPS communication

You can connect to PaperCut NG using either HTTP or HTTPS, however, you can enforce the use of HTTPS in one of the following ways:

To enforce HTTPS communication:

  1. Test the connection to PaperCut NG on port 443:

    1. In a browser, connect to https://<Application ServerAn Application Server is the primary server program responsible for providing the PaperCut user interface, storing data, and providing services to users. PaperCut uses the Application Server to manage user and account information, manage printers, calculate print costs, provide a web browser interface to administrators and end users, and much more. address>.

    2. Check that the URL does not include “:9192” at the end.

  2. Select Options > Advanced.

    The Advanced page is displayed.

  3. In the Security area:

    1. Select the Redirect to HTTPS/SSL if available check box.

    2. If you want to connect using HSTS, select the Use HTTP Strict Transport Security check box.

      Important:

      If you select this option, you must use port 443. For more information about changing the port, see Enable ports 80 (HTTP) and 443 (HTTPS).

  4. Click Apply.

  5. Restart the Application Server. (See Stop and start the Application Server).

  6. Perform a test print job to test all MFDs/printers to ensure they can still submit information to the Application Server.

    Note:

    If you cannot connect to the Application Server after enabling HSTS, it is likely due to either:

    • an invalid SSL certificate
    • the Application Server is running on a port other than 443

    You should roll back your changes:

    1. Log in to the server running the PaperCut NG Application Server.

    2. Connect to the PaperCut NG Application Server web interface using localhost, for example, http://localhost:9191. Non-secure HTTP connections are allowed when connecting from localhost.

    3. Clear the Redirect to HTTPS/SSL and Use HTTP Strict Transport Security check boxes.

    4. Restart the Application Server.
