To enable or disable the Print Selection Service menu item go to System Preferences (click on in upper left corner of screen and select System Preferences from the menu).
In the System Preferences window select "Keyboard".
Select "Services" in the left box and "Print Selection" will be underneath "Pictures" in the right box. Tick the checkbox to enable the service or untick the box to disable the service.
You can also supply a custom hotkey to activate the service. In the screenshot above the hot key is ctrl+shift+p.
Not all apps support Services. If there is an application that does not support Print Selection and you think it should please email us and let us know the name of the application as well as what version of Print Selection you are using.
