Night mode is an automatic setting which takes advantage of the new wide-angle camera that's in the iPhone 11 and 11 Pro models. It's equipped with a larger sensor that is able to let in more light, allowing for brighter photos when the light is low.

'Printopia' and 'FingerPrint' Bring AirPrint Functionality to Shared Printers
While several hacks to enable support for shared printers on AirPrint surfaced, a pair of commercial software releases are now providing a way for everyday users to enable the functionality on Mac OS X Leopard and Snow Leopard once iOS 4.2 finally debuts without the need to modify system files.
Printopia from Ecamm Network installs as a preference pane in System Preferences and allows users to easily select which local and networked printers should be shared to iOS 4.2 devices on the local network. Users can also send print jobs from iOS 4.2 devices directly to their Macs (including Dropbox folders for automatic syncing), allowing for easy export of PDF/JPEG files without the need for actual printing. Printopia is priced at $9.95 with a 7-day free trial available.
