Print
The Lexmark Print application uses ports 80 and 443 to communicate with the LPM server. For more information on opening these ports in your network, contact your system administrator.
Send print jobs to a Lexmark Print Management server or the Lexmark Cloud Services portal using the Lexmark Mobile Print application.
If you cannot do a direct print, then make sure that the printer is supported and ports 9100 and 631 are not blocked.
