Information
By enabling Printer Sharing the computer is set up as a print server to accept print jobs from other computers. Dedicated print servers or direct IP printing should be used instead.
Rationale:
Disabling Printer Sharing mitigates the risk of attackers attempting to exploit the print server to gain access to the system.
Solution
Perform the following to disable Printer Sharing:
Graphical Method:
Open System Preferences
Select Sharing
Uncheck Printer Sharing
Terminal Method:
Run the following command to disable Printer Sharing:
$ sudo cupsctl --no-share-printers
