In Settings → Mobile Print (Illus. below) on your iOS device, you can set up the following:
Reset
All settings will be deleted with next app start.
Update configuration
The app will connect to TPNS (https://api.thinprint.com/tpns) with its next start. It will download Mobile Session Print server’s (new) connection settings. This is, for example, required after an update installation of Mobile Session Print.
