HP announced yesterday that new business printer models will ship with FTP and Telnet services disabled by default. The move is part of a bigger effort to secure all HP business printers, as part of the HP Secure MPS (Managed Print Services) program, which HP set in motion as a result of the growing number of hacked printer incidents.
