While we do not officially support label printing from iPhones, we have found a workaround that can be used in most cases. We have heard your feedback around label printing from phones and are looking to implement this feature in the future.
Go to the Spriggy Schools website on your iPhone. Do not use the Spriggy Schools mobile app to print labels.
Click Print Labels
Select Recess, Lunch or Event
Click the blue Print button
You will now see a page with all of the labels on the screen.
Click the Share button
Select your AirPrint enabled printer
