Registering an iOS device
After the ThinPrint Session Print app has been installed, the mobile device needs to be registered on the ThinPrint Notification Service (TPNS).
This requires a user account with a mail address from the same mail domain that was used to register the Mobile Session Print server on the TPNS (see Registering Mobile Session Print server on TPNS).
- If not already exists, set up an Exchange e-mail account for the relevant user – preferably on the mobile device.

Mail app: E-mail account set up (example)
- Next, start the ThinPrint Session Print app. Confirm the message “Mobile Print Would like to Send You Push Notifications” with OK.
- Enter the user’s e-mail address in the Session Print app (left arrow in following Illus.) and confirm with Send (right arrow).

Session Print app: Enter the e-mail address and confirm with Send (example)
Then the TPNS registers the device for the respective user and sends her or him a confirmation e-mail.
Note: For the first registration of an iOS device, please refer to the section Modifying the Certificate Store of the Mobile Session Print server below.
Go to the Mail app. Open this e-mail, and tap on the Confirm button in the body of the text to confirm the registration.

Mail app: Confirm the mail from TPNS by tapping on Confirm
- A message will appear in the web browser. It shows the successful registration on TPNS.

Web browser: message confirming successful registration
- To finish the registration, switch back to the Session Print app and tap on Continue when e-mail confirmed (arrow in following Illus.) and then on Get started now.

As mentioned above, you can also personalize multiple devices or Session Print apps with the same e-mail address.
Modifying the Certificate Store of the Mobile Session Print server
The very first time you try to register an iOS device, you get the following error message in the Session Print app:
- After this first – unsuccessful – attempt to register an iOS device, you still need to copy the CA certificate for signing device certificates to Trusted Root Certification Authorities in the Certificate Store.
- Finally, restart the Mobile Session Print Server IIS and the Session Print app.
