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

    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.


      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.


    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

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

    2. Connect to the PaperCut NG/MF 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.
